Maven搭建Spring+Struts2+Hibernate项目详解
前言

         这篇主要采用Maven搭建Spring+Struts2+Hibernate的整合项目，复习一下SSH框架，虽然spring提供自己的MVC框架，但是Spring也提供和其他框架的无缝整合，采用组件形式对个框架进行管理，项目实例是按照真实企业里面的开发搭建，也是web的最后一片了。数据库使用mysql，连接池使用的是Druid数据源（这些都无关紧要，可以随时的替换），下面就将详细的介绍一下Maven搭建Spring，Struts2，和hibernation的步奏。

1创建maven的webapp项目，pom.xml配置中引入所需依赖包

引入所需的依赖包，pom.xml内容如下：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

</plugin>
</plugins>

</build>
</project>

以上就是ssh所需的所有依赖包。

 

2引入Spring

         最优先引入的是Spring框架，他是管理其他框架的容器，spring中需要配置的是自动扫描的dao，和service层的注解，然后将其注入为bean，管理。

         配置文件在src/main/java目录下，创建spring的配置文件spring.xml

<?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: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"> <!-- 加载配置文件 -->

<context:property-placeholder location="classpath:config.properties"/>
<!-- 扫描service自动注入为bean -->
<context:component-scan base-package="org.andy.shop.service.impl,org.andy.shop.dao.impl" />

</beans>

2.1、引入日志Log4j配置

   log4j.properties配置内容如下：

### 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 = [spring_struts2_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/spring_struts2_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 = [spring_struts2_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/spring_struts2_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 = [spring_struts2_Hibernate_demo][%p] [%-d{yyyy-MM-dd HH:mm:ss}] %C.%M(%L) | %m%n

2.2、项目配置文件

   添加项目的配置文件config.properties，有spring管理

#application configs

#jdbc druid config
validationQuery = SELECT 1
jdbc.url = jdbc:mysql://localhost:3306/shop?useUnicode=true&characterEncoding=utf-8
jdbc.username = root
jdbc.password = root

#hibernate config
hibernate.dialect = org.hibernate.dialect.MySQLDialect
hibernate.show_sql = true
hibernate.format_sql = false
hibernate.hbm2ddl.auto = update

3、引入Hibernation

   Hibernation的配置主要有如下内容：数据源，SessionFactory，事务等的配置。

   spring-hibernate.xml配置如下（配置文件名可以随便起）

<?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=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.1.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.1.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.1.xsd">

<!-- 配置数据源 使用的是Druid数据源 -->
<bean name="dataSource" class="com.alibaba.druid.pool.DruidDataSource"
init-method="init" destroy-method="close">
<property name="url" value="${jdbc.url}" />
<property name="username" value="${jdbc.username}" />
<property name="password" value="${jdbc.password}" />

<!-- 初始化连接大小 -->
<property name="initialSize" value="0" />
<!-- 连接池最大使用连接数量 -->
<property name="maxActive" value="20" />

<!-- 连接池最小空闲 -->
<property name="minIdle" value="0" />
<!-- 获取连接最大等待时间 -->
<property name="maxWait" value="60000" />
<property name="poolPreparedStatements" value="true" />
<property name="maxPoolPreparedStatementPerConnectionSize"
value="33" />
<!-- 用来检测有效sql -->
<property name="validationQuery" value="${validationQuery}" />
<property name="testOnBorrow" value="false" />
<property name="testOnReturn" value="false" />
<property name="testWhileIdle" value="true" />
<!-- 配置间隔多久才进行一次检测，检测需要关闭的空闲连接，单位是毫秒 -->
<property name="timeBetweenEvictionRunsMillis" value="60000" />
<!-- 配置一个连接在池中最小生存的时间，单位是毫秒 -->
<property name="minEvictableIdleTimeMillis" value="25200000" />
<!-- 打开removeAbandoned功能 -->
<property name="removeAbandoned" value="true" />
<!-- 1800秒，也就是30分钟 -->
<property name="removeAbandonedTimeout" value="1800" />
<!-- 关闭abanded连接时输出错误日志 -->
<property name="logAbandoned" value="true" />
<!-- 监控数据库 -->
<property name="filters" value="mergeStat" />
</bean>

<!-- 配置hibernate的SessionFactory -->
<bean id="sessionFactory"
class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
<!-- 注入数据源 相关信息看源码 -->
<property name="dataSource" ref="dataSource" />
<!-- hibernate配置信息 -->
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">${hibernate.dialect}</prop>
<prop key="hibernate.show_sql">${hibernate.show_sql}</prop>
<prop key="hibernate.format_sql">${hibernate.format_sql}</prop>
<prop key="hibernate.hbm2ddl.auto">${hibernate.hbm2ddl.auto}</prop>
</props>
</property>
<!-- 扫描hibernate注解配置的entity -->
<property name="packagesToScan" value="org.andy.shop.entity" />
</bean>

<!-- 配置事务管理器 -->
<bean id="transactionManager"
class="org.springframework.orm.hibernate4.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory" />
</bean>

<!-- 配置事务增强处理Bean，指定事务管理器 -->
<tx:advice id="transactionAdvice" transaction-manager="transactionManager">
<!-- 配置详细事务处理语义 -->
<tx:attributes>
<tx:method name="insert*" propagation="REQUIRED" />
<tx:method name="update*" propagation="REQUIRED" />
<tx:method name="delete*" propagation="REQUIRED" />

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

<!-- 其他采用默认事务方式 -->
<tx:method name="*" />

</tx:attributes>
</tx:advice>

<!-- Spring aop事务管理 -->
<aop:config>
<!-- 配置切入点 -->
<aop:pointcut id="transactionPointcut"
expression="execution(* org.andy.shop.service.impl.*Impl.*(..))" />
<!-- 指定在txAdvice切入点应用txAdvice事务增强处理 -->
<aop:advisor pointcut-ref="transactionPointcut"
advice-ref="transactionAdvice" />
</aop:config>

</beans>

注意：Hibernation4使用的是SessionFactory而不是HibernationTemplate

 

9、引入Struts2

  配置Struts框架的配置文件，Struts2不同于前面的框架，其配置文件名必须为struts.xml，内容如下：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN" "http://struts.apache.org/dtds/struts-2.3.dtd">
<struts>
<!-- 指定由spring负责action对象的创建 -->
<constant name="struts.objectFactory" value="spring" />
<!-- 所有匹配*.action的请求都由struts2处理 -->
<constant name="struts.action.extension" value="action" />
<!-- 是否启用开发模式 -->
<constant name="struts.devMode" value="true" />
<!-- struts配置文件改动后，是否重新加载 -->
<constant name="struts.configuration.xml.reload" value="true" />
<!-- 设置浏览器是否缓存静态内容 -->
<constant name="struts.serve.static.browserCache" value="false" />
<!-- 请求参数的编码方式 -->
<constant name="struts.i18n.encoding" value="utf-8" />
<!-- 每次HTTP请求系统都重新加载资源文件，有助于开发 -->
<constant name="struts.i18n.reload" value="true" />
<!-- 文件上传最大值 -->
<constant name="struts.multipart.maxSize" value="104857600" />
<!-- 让struts2支持动态方法调用 -->
<constant name="struts.enable.DynamicMethodInvocation" value="true" />
<!-- Action名称中是否还是用斜线 -->
<constant name="struts.enable.SlashesInActionNames" value="false" />
<!-- 允许标签中使用表达式语法 -->
<constant name="struts.tag.altSyntax" value="true" />
<!-- 对于WebLogic,Orion,OC4J此属性应该设置成true -->
<constant name="struts.dispatcher.parametersWorkaround" value="false" />

<!-- 用于CRUD Action的parent package -->
<!-- <package name="crud-default" extends="convention-default">
基于paramsPrepareParamsStack, 增加store interceptor保证actionMessage在redirect后不会丢失
<interceptors>
<interceptor-stack name="crudStack">
<interceptor-ref name="store">
<param name="operationMode">AUTOMATIC</param>
</interceptor-ref>
<interceptor-ref name="paramsPrepareParamsStack" />
</interceptor-stack>
</interceptors>
<default-interceptor-ref name="crudStack" />
</package> -->
<!-- 使用Convention插件,实现约定大于配置的零配置文件风格. 特殊的Result路径在Action类中使用@Result设定. -->
<include file="struts/struts_disk.xml" />
</struts>

上面配置的比较详细，可以按照实际项目，做一下筛检。

其中struts/struts_disk.xml是对具体的action类的配置，当然也可以使用Convention使用注解来实现action的配置，这里使用xml配置如下：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
"http://struts.apache.org/dtds/struts-2.3.dtd">
<struts>
<package name="disk"  extends="json-default">
<action name="disk_powerOn" class="com.supre.manage.action.DiskAction" method="powerOn">
<result type="json"></result>
</action>
<action name="disk_test" class="com.supre.manage.action.DiskAction" method="test">
<result >/success.jsp</result>
</action>
</package>
</struts>

对应的action类中如下：

package com.supre.manage.action;

import java.util.List;
import java.util.Map;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Scope;
import org.springframework.stereotype.Controller;

import com.opensymphony.xwork2.ActionSupport;
import com.supre.manage.entity.Disk;
import com.supre.manage.entity.Drive;
import com.supre.manage.service.DiskService;
import com.supre.manage.service.DriveService;
@Controller(value="diskAction")
@Scope("prototype")
public class DiskAction extends ActionSupport {

private String state;
private Disk disk;
private DriveService driveServic;
private DiskService diskService;
private List<Disk> disks;
private List<Drive> drives;

public String test(){
System.out.println(state);
System.out.println(disk.getDiskName());
System.out.println(disks.size());
return SUCCESS;
}

public String powerOn() {
System.out.println("-----");
Map<String , Drive> oldList = driveServic.listLocalDrive();
String cmd = diskService.spliceCmd("0",disk);
System.out.println(cmd);
//SerialRxtxUtil.displayCustomerScreen(null,DataUtil.hexStringToBytes(cmd));
Map<String, Object> map;
try {
map = driveServic.listChangeDrives(oldList);
drives = (List<Drive>) map.get("data");
state = (String) map.get("state");
} catch (InterruptedException e) {
e.printStackTrace();
}
return SUCCESS;
}

public Disk getDisk() {
return disk;
}

public void setDisk(Disk disk) {
this.disk = disk;
}

public void setDiskService(DiskService diskService) {
this.diskService = diskService;
}

public List<Disk> getDisks() {
return disks;
}

public void setDisks(List<Disk> disks) {
this.disks = disks;
}

public List<Drive> getDrives() {
return drives;
}

public void setDrives(List<Drive> drives) {
this.drives = drives;
}

public void setDriveServic(DriveService driveServic) {
this.driveServic = driveServic;
}
public String getState() {
return state;
}
public void setState(String state) {
this.state = state;
}
}

其中相关的自定义的类为笔者项目中使用到的类，这里主要用于记录格式，测试者可以将该类的中内容移除，用自己项目中的service类

10、配置web容器web.xml

   web.xml是web项目的核心，里面配置了容器启动是的加载文件，以及监听器，过滤器等内容，所以需要我们配置对个框架的启动，加载。其内容如下：

<?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>manage</display-name>

<!-- spring 和  Hibernate的配置文件 -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
classpath:spring.xml
classpath:hibernate-spring.xml
</param-value>
</context-param>

<!-- 编码设置 -->
<filter>
<filter-name>encodingFilter</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>utf-8</param-value>
</init-param>
<init-param>
<param-name>forceEncoding</param-name>
<param-value>true</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>encodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

<!-- 监听servletContext，启动contextConfigLocation中的spring配置信息 -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

<!-- openSessionInView配置 作用是延迟session关闭到view层 -->
<filter>
<filter-name>openSessionInViewFilter</filter-name>
<filter-class>org.springframework.orm.hibernate4.support.OpenSessionInViewFilter</filter-class>
<init-param>
<param-name>singleSession</param-name>
<param-value>true</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>openSessionInViewFilter</filter-name>
<url-pattern>*.action</url-pattern>
</filter-mapping>

<!-- 监听servletContext，启动contextConfigLocation中的spring配置信息 -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

<!-- Struts2 filter -->

<filter>
<filter-name>struts2</filter-name>
<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>*.action</url-pattern>
</filter-mapping>

<!-- 配置session超时时间，单位分钟 -->
<session-config>
<session-timeout>30</session-timeout>
</session-config>

<welcome-file-list>
<welcome-file>/index.jsp</welcome-file>
</welcome-file-list>
</web-app>

11 前端jsp代码如下：

<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
<form action="disk_test.action" method="post">
<input type="text" name="state" value="testpath"/>
名称：<input type="text" name="disk.diskName"/>
List：<input type="text" name="disks[0].diskName" />
<input type="submit" value="提交" />
</form>
</body>
</html>
