Spring3.0MVC和Hibernate基于annotation引文的整合

Spring3.0MVC和Hibernate基于annotation注解的整合
springmvc和hibernate的annotation集合:
首先web.xml

<?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>hibernateAspringmvc</display-name>  <context-param><param-name>contextConfigLocation</param-name><param-value>classpath*:applicationContext*.xml</param-value></context-param><listener><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener><servlet><!-- this is 'spring' name for your spring-servlet.xml --><servlet-name>spring</servlet-name><servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class><load-on-startup>1</load-on-startup></servlet><servlet-mapping><servlet-name>spring</servlet-name><url-pattern>*.xl</url-pattern></servlet-mapping>  <welcome-file-list>    <welcome-file>index.html</welcome-file>    <welcome-file>index.htm</welcome-file>    <welcome-file>index.jsp</welcome-file>    <welcome-file>default.html</welcome-file>    <welcome-file>default.htm</welcome-file>    <welcome-file>default.jsp</welcome-file>  </welcome-file-list></web-app>

然后是applicationContext.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"xmlns:tx="http://www.springframework.org/schema/tx" xmlns:jdbc="http://www.springframework.org/schema/jdbc"xmlns:p="http://www.springframework.org/schema/p"xsi:schemaLocation="http://www.springframework.org/schema/beans         http://www.springframework.org/schema/beans/spring-beans-3.0.xsd         http://www.springframework.org/schema/context         http://www.springframework.org/schema/context/spring-context-3.0.xsd         http://www.springframework.org/schema/tx         http://www.springframework.org/schema/tx/spring-tx-3.0.xsd         http://www.springframework.org/schema/jdbc         http://www.springframework.org/schema/jdbc/spring-jdbc-3.0.xsd"default-autowire="byName" default-lazy-init="true"><!-- this pack must include xxx-servlet.xml's pack. --><context:component-scan base-package="org.xlaohe1" /><bean id="dataSource"value="com.mysql.jdbc.Driver" /><property name="url" value="jdbc:mysql://localhost:3306/test" /><property name="username" value="root" /><property name="password" value="root" /></bean><bean id="sessionFactory"ref="dataSource" />          <!-- 这几句在spring hibernate的注解整合中可以不需要 因为下面的2就是扫描指定路劲下的实体进行映射 -->                <!-- 1======================= --><property name="namingStrategy"><bean /></property><property name="annotatedClasses"><!-- the must have. before this is mapping,now is entity --><list><value>org.xlaohe1.model.User</value></list></property>                <!-- 1======================= --><property name="hibernateProperties"><props><prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop><prop key="hibernate.show_sql">false</prop><prop key="hibernate.cache.provider_class">org.hibernate.cache.EhCacheProvider</prop><prop key="hibernate.cache.use_query_cache">false</prop><prop key="hibernate.jdbc.batch_size">50</prop><prop key="hibernate.cache.use_second_level_cache">false</prop></props></property>                <!-- 2======================= -->                <!-- 自动扫描指定位置下的实体文件进行映射 --><property name="packagesToScan" value="org.xlaohe1.model" />                 <!-- 2======================= --></bean><bean id="transactionManager"ref="sessionFactory" /></bean><tx:annotation-driven transaction-manager="transactionManager" /></beans>  

spring-serlvet.xml

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p"xmlns:mvc="http://www.springframework.org/schema/mvc" 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-3.0.xsd        http://www.springframework.org/schema/context        http://www.springframework.org/schema/context/spring-context.xsd        http://www.springframework.org/schema/mvc        http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">    <!-- 对web包中的所有类进行扫描，以完成Bean创建和自动依赖注入的功能 -->      <context:component-scan base-package="org.xlaohe1.web"/>        <!--启动Spring MVC的注解功能，完成请求和注解POJO的映射      <bean           p:prefix="/WEB-INF/jsp/" p:suffix=".jsp"/>-->                    <bean id="viewResolver" value="org.springframework.web.servlet.view.JstlView"/>              <property name="prefix" value="/WEB-INF/jsp/"/>              <property name="suffix" value=".jsp"/>          </bean>            </beans>  

entity:

userdaoimpl

这个不能写错，
你的dao和service的注解要写对
最后你的controoler的Autowired是接口的不是实现
主要你的Autowired地方看看 <context:component-scan base-package="org.xlaohe1.web"/>

可否把你的lib包用到的jar 贴出来啊？ 配置，代码真的一样。 估计和包有关系吧。
