spring2.5+hibernate基于xml配置的实例

spring+hibernate有基于标签的，有基于xml配置的。现在一般来说都用基于标签的，xml的已经不流行了，但好不容易看到这里，还是记录下来，万一以后需要呢

1、web.xml 

<?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"> <servlet>        <servlet-name>dispatcherServlet</servlet-name>        <!-- 这个是固定的，引入spring处理包 -->        <servlet-class>            org.springframework.web.servlet.DispatcherServlet         </servlet-class>        <!-- 这个是配置文件，可以写成一个，也可以分开写，这个是基于xml开发的 -->        <init-param>            <param-name>contextConfigLocation</param-name>            <param-value>/WEB-INF/hib-config.xml,/WEB-INF/web-config.xml,/WEB-INF/service-config.xml,/WEB-INF/dao-config.xml</param-value>        </init-param>        <load-on-startup>1</load-on-startup>    </servlet>    <!-- 这个是提交的时候，要用.do -->    <servlet-mapping>        <servlet-name>dispatcherServlet</servlet-name>        <url-pattern>*.do</url-pattern>    </servlet-mapping></web-app>

2、hib-config.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:aop="http://www.springframework.org/schema/aop"xmlns:tx="http://www.springframework.org/schema/tx"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.xsdhttp://www.springframework.org/schema/txhttp://www.springframework.org/schema/tx/spring-tx-2.5.xsdhttp://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.5.xsd  http://www.springframework.org/schema/context      http://www.springframework.org/schema/context/spring-context-2.5.xsd"><!-- 扫描包 --><context:component-scan  base-package="com.sxt"/>   <!-- 支持aop注解 --><aop:aspectj-autoproxy /><!-- 配置mysql数据库连接 --><bean id="dataSource"              class="org.apache.commons.dbcp.BasicDataSource">              <property name="driverClassName"                  value="com.mysql.jdbc.Driver">              </property>              <property name="url" value="jdbc:mysql://localhost:3306/myhib"></property>              <property name="username" value="root"></property>              <property name="password" value="123456"></property>    </bean>     <bean id="sessionFactory"         class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">             <property name="dataSource">                 <ref bean="dataSource" />             </property>           <property name="hibernateProperties">                 <props>                 <!-- key的名字前面都要加hibernate. -->                   <prop key="hibernate.dialect">                         org.hibernate.dialect.MySQLDialect                     </prop>                     <prop key="hibernate.show_sql">true</prop>                   <prop key="hibernate.hbm2ddl.auto">update</prop>               </props>           </property>           <!-- 实体类配置 --><property name="packagesToScan"><value>com.sxt.po</value></property>   </bean>  <bean id="hibernateTemplate" class="org.springframework.orm.hibernate3.HibernateTemplate" ><property name="sessionFactory" ref="sessionFactory"></property></bean><!--配置一个JdbcTemplate实例-->  <bean id="jdbcTemplate"  class="org.springframework.jdbc.core.JdbcTemplate">        <property name="dataSource" ref="dataSource"/>   </bean>  <!-- 配置事务管理 --><bean id="txManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager" ><property name="sessionFactory" ref="sessionFactory"></property></bean><tx:annotation-driven transaction-manager="txManager" /><aop:config> <!-- 实现类配置，这里没有写实现类 --><aop:pointcut expression="execution(public * com.sxt.service.impl.*.*(..))" id="businessService"/> <aop:advisor advice-ref="txAdvice" pointcut-ref="businessService" /> </aop:config> <tx:advice id="txAdvice" transaction-manager="txManager" > <tx:attributes> <tx:method name="find*"  read-only="true" propagation="NOT_SUPPORTED"  /> <!-- get开头的方法不需要在事务中运行 。 有些情况是没有必要使用事务的，比如获取数据。开启事务本身对性能是有一定的影响的--> <tx:method name="*"/>    <!-- 其他方法在实务中运行 --> </tx:attributes> </tx:advice> </beans>

3、dao-config.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" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd"><!-- 数据访问层配置 --><bean id="userDao" class="com.sxt.dao.UserDao">  <property name="hibernateTemplate" ref="hibernateTemplate"></property></bean></beans>

4、service-config.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" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">    <!-- 业务逻辑层service配置 --><bean id="userService" class="com.sxt.service.UserService"><property name="userDao" ref="userDao"></property></bean></beans>

5、web-confg.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" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd"><!-- Controller方法调用规则定义 -->    <bean id="paraMethodResolver"        class="org.springframework.web.servlet.mvc.multiaction.ParameterMethodNameResolver">        <property name="paramName" value="action"/>        <property name="defaultMethodName" value="list"/>    </bean>     <!-- 页面View层基本信息设定 -->    <bean id="viewResolver"          class="org.springframework.web.servlet.view.InternalResourceViewResolver">        <property name="viewClass"            value="org.springframework.web.servlet.view.JstlView"/>        <!--<property name="prefix" value="/myjsp/"/>-->        <property name="suffix" value=".jsp"/>    </bean><!-- servlet映射列表,所有控制层Controller的servlet在这里定义-->    <bean id="urlMapping"          class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">        <property name="mappings">            <props>                <prop key="user.do">userController</prop>  <!-- 控制器配置 -->            </props>        </property>    </bean><!-- 控制器配置指向具体的类 --><bean id="userController" class="com.sxt.action.UserController"><property name="userService" ref="userService"></property></bean></beans>

6、UserController.java

package com.sxt.action;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import org.springframework.web.servlet.ModelAndView;import org.springframework.web.servlet.mvc.Controller;import com.sxt.service.UserService;public class UserController implements Controller {private UserService userService;public ModelAndView handleRequest(HttpServletRequest req,HttpServletResponse resp) throws Exception {System.out.println("HelloController.handleRequest()");//返回给页面的数据req.setAttribute("a", "aaaa");userService.add(req.getParameter("uname")); return new ModelAndView("index");}public UserService getUserService() {return userService;}public void setUserService(UserService userService) {this.userService = userService;}}

7、UserDao.java

package com.sxt.dao;import javax.annotation.Resource;import org.springframework.orm.hibernate3.HibernateTemplate;import org.springframework.stereotype.Component;import com.sxt.po.User;public class UserDao {private HibernateTemplate hibernateTemplate;public void add(User u){System.out.println("UserDao.add()");hibernateTemplate.save(u);}public HibernateTemplate getHibernateTemplate() {return hibernateTemplate;}public void setHibernateTemplate(HibernateTemplate hibernateTemplate) {this.hibernateTemplate = hibernateTemplate;}}

8、User.java

package com.sxt.po;import javax.persistence.Entity;import javax.persistence.GeneratedValue;import javax.persistence.GenerationType;import javax.persistence.Id;@Entitypublic class User {@Id@GeneratedValue(strategy=GenerationType.AUTO)private int id;private String uname;public int getId() {return id;}public void setId(int id) {this.id = id;}public String getUname() {return uname;}public void setUname(String uname) {this.uname = uname;}}

9、UserService.java

package com.sxt.service;import javax.annotation.Resource;import org.springframework.stereotype.Component;import com.sxt.dao.UserDao;import com.sxt.po.User;public class UserService {private UserDao userDao;public void add(String uname){System.out.println("UserService.add()");User u = new User();u.setUname(uname);userDao.add(u);}public UserDao getUserDao() {return userDao;}public void setUserDao(UserDao userDao) {this.userDao = userDao;}}

10、index.jsp

<%@ page language="java" import="java.util.*" pageEncoding="gbk"%><%String path = request.getContextPath();String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";%><!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"><html>  <head>    <base href="<%=basePath%>">        <title>My JSP 'index.jsp' starting page</title><meta http-equiv="pragma" content="no-cache"><meta http-equiv="cache-control" content="no-cache"><meta http-equiv="expires" content="0">    <meta http-equiv="keywords" content="keyword1,keyword2,keyword3"><meta http-equiv="description" content="This is my page"><!--<link rel="stylesheet" type="text/css" href="styles.css">-->  </head>    <body><h1>${requestScope.a}</h1>  </body></html>

11、reg.jsp

<%@ page language="java" import="java.util.*" pageEncoding="gbk"%><%String path = request.getContextPath();String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";%><!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"><html>  <head>    <base href="<%=basePath%>">        <title>My JSP 'reg.jsp' starting page</title>    <meta http-equiv="pragma" content="no-cache"><meta http-equiv="cache-control" content="no-cache"><meta http-equiv="expires" content="0">    <meta http-equiv="keywords" content="keyword1,keyword2,keyword3"><meta http-equiv="description" content="This is my page">  </head>    <body><form action=user.do>用户名：<input type=text name=uname /><br/><input type=hidden name=method value="reg"/><input type=submit value= 注册   /></form>  </body></html>

需要用到的jar包

数据库是mysql数据库，表名如下：

CREATE TABLE `user` (
  `id` bigint(11) NOT NULL AUTO_INCREMENT COMMENT '主键',
  `uname` varchar(24) DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1;

注意下面两个错误

org.hibernate.HibernateException: The database returned no natively generated identity value
数据库返回的没有本地生成的标识值的错误。

alter table t_news change  id id  int not null  auto_increment;

java.sql.SQLException: Field 'id' doesn't have a default value

ID的自增长没有加上去，加上就OK了
