Spring2.5 + Hibernate3.2 集成实例(CTO)

首先需要准备SPRING和HIBERNATE 相应的JAR包,在ECLIPSE 中新建一个WEB工程,将解压的SPRING中的 /dist/modules 下的JAR和HIBERNATE 中的 hibernate3.jar 和 /lib/ 目录下的包全部拷入到工程的LIB目录,这时我们就可以真正开始编写SPRING+HIBERNATE应用了,首先我们建立一个SPRING的控制器,代码清单如下:

package com.spring25.action;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;

import com.spring25.service.ILoginService;

/* 描述该bean为springMVC控制器，将由spring容器来创建和管理 */
@Controller
public class LoginController {

/* 自动装载 */
@Autowired
private ILoginService loginService;

/* 将该控制器的login方法与login.do 的请求进行关联,真正实现控制功能的是 @RequestMapping 注解 */
/*
* springMVC 控制请求处理的方式有如下几种:
* 1、直接在class头加 @RequestMapping("login.do"),能后在请求处理的方法头上加@RequestMapping,表明该请求由该控制器的该方法处理
* 2、在方法头上加 @RequestMapping("login.do"),当该请求到达时将会调用这个方法处理
* 3、通过参数：该控制处理的请求地址只有一个,但又想通过参数来调用不同的方法,这个时候就可以在类的头上加@RequestMapping("users.do")
*    处理方法头上加@RequestMapping(params="method=login"),这是一个分流规则,其中 method=login就是请求中带的参数
* 4、根据特殊的表单提交方法进行处理,如: @RequestMapping(params="method=login",method=RequestMethod.POST)
*    这样只能当提交方法是 POST 时 login 方法才会处理该请求
* */
@RequestMapping("/login.do")
public String login(String userName,String password,ModelMap model){
boolean succeed = this.getLoginService().login(userName,password);
model.addAttribute("userName", userName);
/* 返回一个String,该名称应为逻辑视图的名称 */
if(succeed){
return "error";
}
return "success";
}
}

HIBERNATE 持久类

package com.spring25.hibernate;

import java.io.Serializable;
import java.util.Date;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.Table;

@SuppressWarnings("serial")
@Entity
@Table(name="users")  //持久类与表的映射
public class Users implements Serializable{

private Integer uid;

private String userName;

private String password;

private Date birthday;

public Users(){

}

@Id
@GeneratedValue
public Integer getUid() {
return uid;
}

public void setUid(Integer uid) {
this.uid = uid;
}

@Column(name="username",nullable=true,length=20)
public String getUserName() {
return userName;
}

public void setUserName(String userName) {
this.userName = userName;
}

public void setPassword(String password) {
this.password= password;
}

@Column(name="password",nullable=true,length=20)
public String getPassword() {
return password;
}

@Column(name="birthday")
public Date getBirthday() {
return birthday;
}

public void setBirthday(Date birthday) {
this.birthday = birthday;
}
}

接下来建立一个业务类

package com.spring25.service.impl;

import com.spring25.dao.ILoginDao;
import com.spring25.service.ILoginService;

public class LoginService implements ILoginService {

private ILoginDao loginDao;

public ILoginDao getLoginDao() {
return loginDao;
}

public void setLoginDao(ILoginDao loginDao) {
this.loginDao = loginDao;
}

public boolean login(String userName,String password) {
return this.getLoginDao().login(userName,password);
}

}

数据处理层代码

package com.spring25.dao.impl;

import org.hibernate.Query;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;

import com.spring25.dao.ILoginDao;

public class LoginDaoImpl extends HibernateDaoSupport implements ILoginDao{

public boolean login(String userName,String password) {
Query query = this.getSession(true).createQuery("from Users where userName=:userName and password=:password");
query.setParameter("userName", userName);
query.setparameter("password",password);
if(query.list().size() > 0){
return true;
}
return false;
}

}

接下来我们需要添加SPRING配置文件,其中applicationContext.xml为业务层配置,spring25annmvc-servlet.xml 声明SPRING MVC 相应配置

spring25annmvc-servlet.xml 内容如下：

<?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: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-2.5.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd"> 
<!--
在web.xml 中配置了 spring25annmvc 的模块,根据spring的规范,需要在 spring25annmvc-servlet.xml 定义springMVC的具体配置
-->
<!-- 对 action 包中的所有 Controller 类进行扫描,以完成自动装载功能 -->
<context:component-scan base-package="com.spring25.action"></context:component-scan>
<!-- 启动springMVC的注解驱动 -->
<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"></bean>

<!-- 模型视图的解析 -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver" p:suffix=".jsp"></bean>

</beans>

applicationContext.xml 配置如下：

<?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:p="http://www.springframework.org/schema/p"

<!-- JDBC 数据源 -->
<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="com.microsoft.jdbc.sqlserver.SQLServerDriver"></property>
<property name="url" value="jdbc:microsoft:sqlserver://192.168.0.180:1433;databaseName=pubs"></property>
<property name="username" value="holpe"></property>
<property name="password" value="holpe20080801"></property>
</bean>

<bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
<property name="dataSource" ref="dataSource"></property>
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">
org.hibernate.dialect.SQLServerDialect
</prop>
<prop key="hibernate.show_sql">false</prop>
</props>
</property>

<property name="annotatedClasses">
<list>
<value>com.spring25.hibernate.Users</value>
</list>
</property>
</bean>
<!-- hibernate 模板,用来代替 sessionFactory -->
<bean id="hibernateTemplate" class="org.springframework.orm.hibernate3.HibernateTemplate">
<property name="sessionFactory" ref="sessionFactory"/>
<property name="cacheQueries" value="true"/>
</bean>

<bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
<property name="dataSource" ref="dataSource"/>
<property name="sessionFactory" ref="sessionFactory"/>
</bean>
<!--  声明式事务管理 -->
<aop:config>
<aop:pointcut id="servicePointcut" expression="execution(* com.spring25.service.*.*(..))"/>
<aop:advisor advice-ref="txAdvice" pointcut-ref="servicePointcut"/>
</aop:config>
<!--事务控制-->
<tx:advice id="txAdvice" transaction-manager="transactionManager">
<tx:attributes>
<tx:method name="login*" read-only="true"/>
</tx:attributes>
</tx:advice>

<bean id="loginDao" class="com.spring25.dao.impl.LoginDaoImpl">
<property name="hibernateTemplate" ref="hibernateTemplate"/>
</bean>

<bean id="loginService" class="com.spring25.service.impl.LoginService">
<property name="loginDao" ref="loginDao"/>
</bean>
</beans>

最后配置web.xml 和建立相应 jsp 文件

web.xml 代码如下:

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"> 
<!-- spring 相关配置 -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/applicationContext.xml</param-value>
</context-param>
<!-- spring 启动监听器 -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

<!-- 处理请求的 servlet,它将加载 WEB-INF/spring25annmvc-servlet.xml下的配置文件,以启动springMVC模块 -->
<servlet>
<servlet-name>spring25annmvc</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>2</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>spring25annmvc</servlet-name>
<url-pattern>*.do</url-pattern>
</servlet-mapping>

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

login.jsp

好了，以上就是整个编写的过程,是不是很简单呢！ 经过运行后完全正确
