SpringMVC和Hibernate整合

hibernate由spring管理，配置文件如下：

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: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-3.0.xsd 
           http://www.springframework.org/schema/aop  
           http://www.springframework.org/schema/aop/spring-aop-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/context   
           http://www.springframework.org/schema/context/spring-context-3.0.xsd"> 
        <!-- 配置扫瞄注解service,controller --> 
        <context:annotation-config/> 
        <context:component-scan base-package="扫瞄的包名" scoped-proxy="targetClass"> 
    <!--         <context:exclude-filter type="annotation" expression="cn.bonoon.controllers.*"/> --> 
        </context:component-scan> 
     
        <!-- 配置数据库连接 --> 
        <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"> 
            <property name="driverClassName" value="com.mysql.jdbc.Driver"/> 
            <property name="url" value="jdbc:mysql://localhost:3306/数据库名?useUnicode=true&characterEncoding=utf8"/> 
            <property name="username" value="root"/> 
            <property name="password" value=""/> 
        </bean> 
        <!-- 配置hibernate相关信息 --> 
        <bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean"> 
            <property name="dataSource" ref="dataSource"/> 
            <property name="hibernateProperties"> 
                <props> 
                    <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> 
             
                <!-- 以下列表写入实体类 --> 
            <property name="annotatedClasses"> 
                <list>中间写入hibernate注解的实体</list> 
            </property> 
        </bean> 
        <bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager"> 
            <property name="sessionFactory" ref="sessionFactory"/> 
        </bean> 
        <!-- 使用annotation定义事务 --> 
        <tx:annotation-driven transaction-manager="transactionManager" /> 
    </beans> 

有了applicationContext再在web.xml在配置一下便可同时使用spring和hibernate了，但是要使用spring mvc ，还得在web里做一点手脚，具体如下：


    <?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" version="2.5"> 
    <!-- 上下文配置文件 --> 
      <context-param> 
        <description>spring config</description> 
        <param-name>contextConfigLocation</param-name> 
        <param-value>/WEB-INF/applicationContext.xml</param-value> 
      </context-param> 
      <listener> 
        <description>spring listerner</description> 
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> 
      </listener> 
       
    <!--   配置spring mvc的相关内容，此处的servlet-name任意，但必须有<your servlet-name>-servlet.xml与之对应 --> 
      <servlet> 
        <servlet-name>springmvc</servlet-name> 
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> 
        <load-on-startup>2</load-on-startup> 
      </servlet> 
      <servlet-mapping> 
        <servlet-name>springmvc</servlet-name> 
    <!--     配置对应以.do结尾的请求 --> 
        <url-pattern>*.do</url-pattern>   
      </servlet-mapping> 
     
     
    <!-- 配置过滤器，同时把所有的请求都转为utf-8编码 --> 
        <filter> 
            <filter-name>Spring character encoding filter</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> 
        </filter> 
        <filter-mapping> 
            <filter-name>Spring character encoding filter</filter-name> 
            <url-pattern>/*</url-pattern> 
        </filter-mapping> 
       
    <!--     配置找不到页面时返回的页面 --> 
      <error-page>  
          <error-code>404</error-code>  
          <location>/error/404.html</location>  
      </error-page>  
       
    <!--   配置项目主页 --> 
      <session-config> 
        <session-timeout>30</session-timeout> 
      </session-config> 
      <welcome-file-list> 
        <welcome-file>login.jsp</welcome-file> 
      </welcome-file-list> 
    </web-app> 


如上面配置文件的注释所说，由于配置了spring mvc ，还得有相关的文件，以上面的配置对应的文件名为:

springmvc-servlet.xml
[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: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"> 
     
     
        <!-- 对定义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="cn.bonoon" /> 
     
        <!-- 启动spring mvc的注解功能，完成请求和注解POJO的映射 --> 
        <bean 
            class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"> 
    <!--         配置信息转换，将用@responsebody注解的返回值转换为json返回前台，编码为utf-8--> 
            <property name="messageConverters"> 
                <list> 
                    <bean 
                        class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter"> 
                        <property name="supportedMediaTypes"> 
                            <list> 
                                <value>application/json;charset=UTF-8</value> 
                            </list> 
                        </property> 
                    </bean> 
                </list> 
            </property> 
        </bean> 
     
     
    <!-- 上传文件时需要用到的分解器，默认将编码转为utf-8 --> 
        <bean id="multipartResolver"   
            class="org.springframework.web.multipart.commons.CommonsMultipartResolver">   
            <property name="defaultEncoding"> 
                <value>UTF-8</value> 
            </property> 
        </bean>   
     
        <!-- 对模型视图名称的解析，即在模型视图名称添加前后缀 --> 
        <bean 
            class="org.springframework.web.servlet.view.InternalResourceViewResolver" 
            p:prefix="" p:suffix=".jsp" /> 
     
     
    </beans> 



按照本文所提到的配置文件配置的话，三个文件全部都放在web-inf里面，其中springmvc-servlet.xml里面配置的信息转换用到了两个外加的包

jackson-core-asl-1.4.2.jar

jackson-mapper-asl-1.4.2.jar
