Maven搭建SpringMVC+Hibernate项目详解

2015-06-07 00:25 671 查看

原文:http://blog.csdn.net/fengshizty/article/details/43635305http://blog.csdn.net/fengshizty/article/details/43635305

1、设计数据库：设计好表结构，最好符合3NF，采用Hibernate tools将设计好的表自动生成对应的实体entity。

1、创建Maven项目，按需映入Maven包依赖。

2、搭建Spring：配置Spring对控件层Bean的注入。

3、搭建Hibernate：配置数据源，配置SessionFactory，配置事务，以及二级缓存ehcache的配置。

4、测试Spring+Hibernate的框架搭建，写单元测试JUnit，测试事务配置等。

5、映入SpringMVC：配置SpringMVC配置信息。

6、配置web.xml容器

7、测试三个框架的整合：Maven编译打包部署服务器，测试。

1、数据库设计

设计一个权限、角色、用户的表。自然如果一个用户可以有多个角色，一个角色多个用户所拥有；一个角色拥有多个权限，一个权限对应多个角色。所以按照数据库表结构设计，符合3NF的话我们需要5张表进行存在。表的具体信息就不列出了（可以下在源码，里面还有数据库），表关系如下：

这里面ID才用到是java的UUID（36位）

2、创建Maven项目，编写pom.xml文件

创建一个Maven的webapp项目，编写pom.xml文件，引入所需的包依赖，我这里就将所需的全部的映入了。

pom.xml文件内容如下:

3、引入Spring配置

编写配置文件，配置文件放在src/main/resources资源目录下（下同）。

项目所需的配置信息config.properties

[plain] view
plaincopy

#application configs

#jdbc c3p0 config

jdbc.driver = com.mysql.jdbc.Driver

jdbc.url = jdbc:mysql://localhost:3306/work?useUnicode=true&characterEncoding=utf-8

jdbc.username = root

jdbc.password = 12345

#hibernate config

hibernate.dialect = org.hibernate.dialect.MySQLDialect

hibernate.show_sql = true

hibernate.format_sql = false

hibernate.hbm2ddl.auto = update

hibernate.cache.use_second_level_cache = true

hibernate.cache.use_query_cache = true

hibernate.cache.region.factory_class = org.hibernate.cache.ehcache.EhCacheRegionFactory

hibernate.cache.provider_configuration_file_resource_path = ehcache.xml

3.1、spring配置

spring.xml的配置文件如下：

[html] view
plaincopy

3.2、引入日志文件配置Log4j

log4j.properties的配置文件如下：

[plain] view
plaincopy

### set log levels ###

log4j.rootLogger = INFO , C , D , E

### console ###

log4j.appender.C = org.apache.log4j.ConsoleAppender

log4j.appender.C.Target = System.out

log4j.appender.C.layout = org.apache.log4j.PatternLayout

log4j.appender.C.layout.ConversionPattern = [springmvc_hibernate_demo][%p] [%-d{yyyy-MM-dd HH:mm:ss}] %C.%M(%L) | %m%n

### log file ###

log4j.appender.D = org.apache.log4j.DailyRollingFileAppender

log4j.appender.D.File = ../logs/springmvc_hibernate_demo.log

log4j.appender.D.Append = true

log4j.appender.D.Threshold = INFO

log4j.appender.D.layout = org.apache.log4j.PatternLayout

log4j.appender.D.layout.ConversionPattern = [springmvc_hibernate_demo][%p] [%-d{yyyy-MM-dd HH:mm:ss}] %C.%M(%L) | %m%n

### exception ###

log4j.appender.E = org.apache.log4j.DailyRollingFileAppender

log4j.appender.E.File = ../logs/springmvc_hibernate_demo_error.log

log4j.appender.E.Append = true

log4j.appender.E.Threshold = ERROR

log4j.appender.E.layout = org.apache.log4j.PatternLayout

log4j.appender.E.layout.ConversionPattern = [sspringmvc_hibernate_demo][%p] [%-d{yyyy-MM-dd HH:mm:ss}] %C.%M(%L) | %m%n

4、Hibernate配置

Hibernate的配置主要包括：配置数据源c3p0，配置SessionFactory，配置事务管理器，配置事务管理，其spring-hibernate.xml文件如下：

[html] view
plaincopy

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:tx="http://www.springframework.org/schema/tx"

xmlns:aop="http://www.springframework.org/schema/aop"

xsi:schemaLocation="

</props>

</property>



<property name="packagesToScan" value="org.andy.work.entity" />

</bean>



<bean id="transactionManager"

class="org.springframework.orm.hibernate4.HibernateTransactionManager">

<property name="sessionFactory" ref="sessionFactory" />

</bean>



<tx:advice id="transactionAdvice" transaction-manager="transactionManager">



<tx:attributes>

<tx:method name="find*" propagation="SUPPORTS" read-only="true" />

<tx:method name="select*" propagation="SUPPORTS" read-only="true" />

<tx:method name="load*" propagation="SUPPORTS" read-only="true" />



<tx:method name="*" />

</tx:attributes>

</tx:advice>



<aop:config>



<aop:pointcut id="transactionPointcut"

expression="execution(* org.andy.work.service..*Impl.*(..))" />



<aop:advisor pointcut-ref="transactionPointcut"

advice-ref="transactionAdvice" />

</aop:config>

</beans>

上面配置了二级缓存，ehcache，相关的具体信息查看上一篇Hibernate二级缓存以及ehcache的搭建配置，下面是二级缓存的配置。

4.1、ehcache.xml的配置

[html] view
plaincopy

<?xml version="1.0" encoding="UTF-8"?>

<ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="../config/ehcache.xsd">

<diskStore path="D:/ehcache" />



<defaultCache

maxElementsInMemory="1000"

eternal="false"

timeToIdleSeconds="120"

timeToLiveSeconds="120"

maxElementsOnDisk="1000000"

overflowToDisk="true"

memoryStoreEvictionPolicy="LRU">

</defaultCache>



<cache

name="org.andy.work.entity.AcctUser"

maxElementsInMemory="2"

memoryStoreEvictionPolicy="LRU"

eternal="true"

diskPersistent="false"

overflowToDisk="false"

maxElementsOnDisk="1000000" />

</ehcache>

上面Hibernate二级缓存ehcache存放磁盘是D:/ehcache

5、生成业务entity实体

设计好数据表后，Hibernate的实体有工具Hibernate tools自动生成，Eclipse需要安装Hibernate tools插件（我在线安装过几次都不成功，推荐使用links离线安装，附录将介绍），所以不需要手工的书写，下面就贴一个用户信息的实体，AcctUser.java

[java] view
plaincopy

package org.andy.work.entity;

// Generated 2015-2-3 10:43:00 by Hibernate Tools 4.0.0

import java.util.Date;

import java.util.HashSet;

import java.util.Set;

import javax.persistence.Column;

import javax.persistence.Entity;

import javax.persistence.FetchType;

import javax.persistence.Id;

import javax.persistence.JoinColumn;

import javax.persistence.JoinTable;

import javax.persistence.ManyToMany;

import javax.persistence.Table;

import javax.persistence.Temporal;

import javax.persistence.TemporalType;

import org.hibernate.annotations.Cache;

import org.hibernate.annotations.CacheConcurrencyStrategy;

import com.fasterxml.jackson.annotation.JsonIgnoreProperties;

/**

* AcctUser generated by hbm2java

*/

@Entity

@Table(name = "acct_user", catalog = "work")

@Cache(usage = CacheConcurrencyStrategy.READ_WRITE)

public class AcctUser implements java.io.Serializable {

/**

*

*/

private static final long serialVersionUID = 6980093847795726310L;

private String id;

private String nickName;

private String telephone;

private Date registerTime;

private Set<AcctRole> acctRoles = new HashSet<AcctRole>(0);

public AcctUser() {

}

public AcctUser(String id, String nickName) {

this.id = id;

this.nickName = nickName;

}

public AcctUser(String id, String nickName, String telephone,

Date registerTime, Set<AcctRole> acctRoles) {

this.id = id;

this.nickName = nickName;

this.telephone = telephone;

this.registerTime = registerTime;

this.acctRoles = acctRoles;

}

@Id

@Column(name = "id", unique = true, nullable = false, length = 36)

public String getId() {

return this.id;

}

public void setId(String id) {

this.id = id;

}

@Column(name = "nick_name", nullable = false)

public String getNickName() {

return this.nickName;

}

public void setNickName(String nickName) {

this.nickName = nickName;

}

@Column(name = "telephone")

public String getTelephone() {

return this.telephone;

}

public void setTelephone(String telephone) {

this.telephone = telephone;

}

@Temporal(TemporalType.TIMESTAMP)

@Column(name = "register_time", length = 19)

public Date getRegisterTime() {

return this.registerTime;

}

public void setRegisterTime(Date registerTime) {

this.registerTime = registerTime;

}

@JsonIgnoreProperties(value={"acctUsers", "acctAuthorities"})

@ManyToMany(fetch = FetchType.LAZY)

@Cache(usage = CacheConcurrencyStrategy.READ_WRITE)

@JoinTable(name = "acct_user_role", catalog = "work", joinColumns = { @JoinColumn(name = "user_id", nullable = false, updatable = false) }, inverseJoinColumns = { @JoinColumn(name = "role_id", nullable = false, updatable = false) })

public Set<AcctRole> getAcctRoles() {

return this.acctRoles;

}

public void setAcctRoles(Set<AcctRole> acctRoles) {

this.acctRoles = acctRoles;

}

}

上面有几个需要注意的：

上面大多数都是Hibernate tools自动生成的，但是有几个需要手动添加：

1、如果这个实体使用二级缓存的话，需要添加@cache注解；

2、如果该实体里面还有集合元素（set， map，list），如果实体要采用二级缓存，那么这些集合元素必须也添加@cache注解。

3、@JsonIgnoreProperties注解是为了防止SpringMVC在json返回时产生循环输出使用，如果不配置的话就会出现json死循环（还有多对多，一对多的属性时）。

4、@JsonIgnore这个是在转换成json是忽略该属性，而@JsonIgnoreProperties(value={"acctUsers", "acctAuthorities"})则是忽略acctRoles里面的acctUsers和acctAuthorites属性。

6、创建Dao层

6.1Dao接口

Dao层和Service层我们肯定采用的是面相接口编程的思想，所以，我们先定义一个通用的Dao接口，GenericDao.java

[java] view
plaincopy

package org.andy.work.dao;

import java.io.Serializable;

import java.util.List;

/**

* 创建时间：2015-2-6 下午2:26:42

*

* @author andy

* @version 2.2

*

* Dao通用接口

*/

interface GenericDao<T, PK extends Serializable> {

T load(PK id);

T get(PK id);

List<T> findAll();

void persist(T entity);

PK save(T entity);

void saveOrUpdate(T entity);

void delete(PK id);

void flush();

}

在定义具体的UserDao.java接口

[java] view
plaincopy

package org.andy.work.dao;

import org.andy.work.entity.AcctUser;

/**

* 创建时间：2015-2-6 下午2:43:50

*

* @author andy

* @version 2.2

*

* 用户Dao接口

*/

public interface UserDao extends GenericDao<AcctUser, String> {

}

6.2、Dao层实现类

我们需要将Dao层的实现类注入为bean，所以需要添加@Repository注解，UserDaoImpl如下：

[java] view
plaincopy

package org.andy.work.dao.impl;

import java.util.List;

import org.andy.work.dao.UserDao;

import org.andy.work.entity.AcctUser;

import org.hibernate.Session;

import org.hibernate.SessionFactory;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.stereotype.Repository;

/**

* 创建时间：2015-2-6 下午2:45:14

*

* @author andy

* @version 2.2

*/

@Repository("userDao")

public class UserDaoImpl implements UserDao {

@Autowired

private SessionFactory sessionFactory;

private Session getCurrentSession() {

return this.sessionFactory.getCurrentSession();

}

@Override

public AcctUser load(String id) {

return (AcctUser) this.getCurrentSession().load(AcctUser.class, id);

}

@Override

public AcctUser get(String id) {

return (AcctUser) this.getCurrentSession().get(AcctUser.class, id);

}

@SuppressWarnings("unchecked")

@Override

public List<AcctUser> findAll() {

List<AcctUser> acctUsers = this.getCurrentSession().createQuery("from AcctUser").setCacheable(true).list();

return acctUsers;

}

@Override

public void persist(AcctUser entity) {

this.getCurrentSession().persist(entity);

}

@Override

public String save(AcctUser entity) {

return (String) this.getCurrentSession().save(entity);

}

@Override

public void saveOrUpdate(AcctUser entity) {

this.getCurrentSession().saveOrUpdate(entity);

}

@Override

public void delete(String id) {

AcctUser entity = this.load(id);

this.getCurrentSession().delete(entity);

}

@Override

public void flush() {

this.getCurrentSession().flush();

}

}

7、创建Service层

7.1、Service层接口

[java] view
plaincopy

package org.andy.work.service;

import java.util.List;

import org.andy.work.entity.AcctUser;

/**

* 创建时间：2015-2-6 下午3:18:57

*

* @author andy

* @version 2.2

* userService接口

*/

public interface UserService {

AcctUser load(String id);

AcctUser get(String id);

List<AcctUser> findAll();

void persist(AcctUser entity);

String save(AcctUser entity);

void saveOrUpdate(AcctUser entity);

void delete(String id);

void flush();

}

7.2、service层实现类

UserServiceImpl就需要注入上面定义的Dao层bean。

[java] view
plaincopy

package org.andy.work.service.impl;

import java.util.List;

import org.andy.work.dao.UserDao;

import org.andy.work.entity.AcctUser;

import org.andy.work.service.UserService;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.stereotype.Service;

/**

* 创建时间：2015-2-6 下午3:24:16

*

* @author andy

* @version 2.2 UserService 的实现

*/

@Service("userService")

public class UserServiceImpl implements UserService {

@Autowired

private UserDao userDao;

@Override

public AcctUser load(String id) {

return userDao.load(id);

}

@Override

public AcctUser get(String id) {

return userDao.get(id);

}

@Override

public List<AcctUser> findAll() {

return userDao.findAll();

}

@Override

public void persist(AcctUser entity) {

userDao.persist(entity);

}

@Override

public String save(AcctUser entity) {

return userDao.save(entity);

}

@Override

public void saveOrUpdate(AcctUser entity) {

userDao.saveOrUpdate(entity);

}

@Override

public void delete(String id) {

userDao.delete(id);

}

@Override

public void flush() {

userDao.flush();

}

}

8、测试Spring和Hibernate的整合

我们可以在src/test/java编写测试类，测试上面的配置，如果测试成功已经基本大功告成。

[java] view
plaincopy

package org.andy.work.service;

import java.util.Date;

import java.util.List;

import java.util.UUID;

import org.andy.work.entity.AcctUser;

import org.apache.log4j.Logger;

import org.junit.Test;

import org.junit.runner.RunWith;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.test.context.ContextConfiguration;

import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

import com.alibaba.fastjson.JSON;

/**

* 创建时间：2015-2-6 下午3:31:07

*

* @author andy

* @version 2.2

*/

@RunWith(SpringJUnit4ClassRunner.class)

@ContextConfiguration(locations = { "classpath:spring.xml",

"classpath:spring-hibernate.xml" })

public class TestUserService {

private static final Logger LOGGER = Logger

.getLogger(TestUserService.class);

@Autowired

private UserService userService;

@Test

public void save() {

AcctUser acctUser = new AcctUser();

acctUser.setId(UUID.randomUUID().toString());

acctUser.setNickName("andy");

acctUser.setRegisterTime(new Date());

acctUser.setTelephone("13022221111");

String id = userService.save(acctUser);

LOGGER.info(JSON.toJSONString(id));

}

}

9、引入SpringMVC

添加spring-mvc.xml文件

[html] view
plaincopy

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"

xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xmlns:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context"

xsi:schemaLocation="http://www.springframework.org/schema/beans

http://www.springframework.org/schema/beans/spring-beans-4.1.xsd

http://www.springframework.org/schema/context

http://www.springframework.org/schema/context/spring-context-4.1.xsd

http://www.springframework.org/schema/mvc

http://www.springframework.org/schema/mvc/spring-mvc-4.1.xsd">



<context:component-scan base-package="org.andy.work.controller" />



<mvc:annotation-driven>



<mvc:message-converters register-defaults="true">

<bean

class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">

<property name="supportedMediaTypes">

<list>

<value>text/html;charset=UTF-8</value>

<value>application/json;charset=UTF-8</value>

</list>

</property>

</bean>

</mvc:message-converters>

</mvc:annotation-driven>



<bean

class="org.springframework.web.servlet.view.InternalResourceViewResolver">

<property name="viewClass"

value="org.springframework.web.servlet.view.JstlView" />

<property name="prefix" value="/WEB-INF/views" />

<property name="suffix" value=".jsp" />

</bean>

</beans>

上面配置了包扫描Controller，将@Controller注入为spring的bean。以及springmvc的json处理，和视图层的配置。

10、配置web.xml容器

web容器是web项目的大脑，所以web容器，首先需要引入spring，让spring管理各个框架，并将其注入为bean。然后配置控制层的filter信息。并且配置了springmvc拦截的url为以.hmls结尾的请求。

web.xml文件如下：

[html] view
plaincopy

<?xml version="1.0" encoding="UTF-8"?>

<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"

xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"

id="WebApp_ID" version="2.5">

<display-name>springmvc_demo</display-name>

11、创建控制层Controller

控制层UserController

[java] view
plaincopy

package org.andy.work.controller;

import java.util.List;

import org.andy.work.entity.AcctUser;

import org.andy.work.service.UserService;

import org.apache.log4j.Logger;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.stereotype.Controller;

import org.springframework.ui.ModelMap;

import org.springframework.web.bind.annotation.PathVariable;

import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.web.bind.annotation.ResponseBody;

/**

* 创建时间：2015-2-7 上午11:49:00

* @author andy

* @version 2.2

* 描述：用户Controller

*/

@Controller

@RequestMapping("/user")

public class UserController {

private static final Logger LOGGER = Logger.getLogger(UserController.class);

@Autowired

private UserService userService;

@RequestMapping("/showInfo/{userId}")

public String showUserInfo(ModelMap modelMap, @PathVariable String userId){

LOGGER.info("查询用户：" + userId);

AcctUser userInfo = userService.load(userId);

modelMap.addAttribute("userInfo", userInfo);

return "/user/showInfo";

}

@RequestMapping("/showInfos")

public @ResponseBody List<AcctUser> showUserInfos(){

LOGGER.info("查询用户全部用户");

List<AcctUser> userInfos = userService.findAll();

return userInfos;

}

}

12、创建视图层

在src/main/webapp/WEB-INF/views下创建user/showInfo.jsp

[html] view
plaincopy

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>

<%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>

<%@taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt"%>

<%

String path = request.getContextPath();

String basePath = request.getScheme() + "://"

+ request.getServerName() + ":" + request.getServerPort()

+ path + "/";

%>

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<html>

<head>

<base href="<%=basePath%>" />

<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

<script type="text/javascript" src="js/jquery-1.9.1.min.js"></script>

<title>userInfo</title>

</head>

<body>

用户信息昵称： ${userInfo.nickName} 用户id：${userInfo.id} 用户电话:${userInfo.telephone } 注册时间：

<fmt:formatDate value="${userInfo.registerTime }" pattern="yyyy-MM-dd HH:mm:ss" />

角色：[

<c:forEach items="${ userInfo.acctRoles}" var="role">

${role.name } 权限[

<c:forEach items="${ role.acctAuthorities}" var="authority">

${authority.name }

</c:forEach> ]

</c:forEach>

]

<br /> ajax显示全部用户信息：

<div id="show_all_user"></div>

</body>

<script type="text/javascript">

$.ajax({

type : "get",

url : "user/showInfos.htmls",

dataType : "json",

success : function(data) {

$(data).each(

function(i, user) {

var p = "<p>昵称:" + user.nickName + " 电话:"

+ user.telephone + " 注册时间:"

+ user.registerTime + " id:" + user.id +

"</p>";

$("#show_all_user").append(p);

});

},

async : true

});

</script>

</html>

13、部署服务器测试

使用Maven打包部署：clean compile package

部署到tomcat，测试

主要测试上面的 http://localhost:8080/springmvc_hibernate_demo/user/showInfo/6e5afb1d-50e1-45fe-b6fe-b9e399415387.htmls
和http://localhost:8080/springmvc_hibernate_demo/user/showInfos.htmls （json数据返回）

上面视图层就包含了这两条url请求的测试：

ok，到此Spring+SpringMVC+Hibernate搭建完毕。
