Spring MVC + JPA开发中遇到对象延迟加载,session关闭的情况解决方法

Spring MVC + JPA开发中遇到对象延迟加载,session关闭的情况解决方法如下:

xml 代码

<bean name="openEntityManagerInViewInterceptor"
    class="org.springframework.orm.jpa.support.OpenEntityManagerInViewInterceptor">
    <property name="entityManagerFactory">
        <ref bean="entityManagerFactory" />
    property>
bean>

<bean id="viewResolver"
    class="org.springframework.web.servlet.view.InternalResourceViewResolver">
    <property name="prefix" value="/WEB-INF/jsp/" />
    <property name="suffix" value=".jsp" />
bean>

<bean id="simpleUrlHandlerMapping"
    class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
    <property name="interceptors">
        <list>
            <ref bean="openEntityManagerInViewInterceptor" />
        list>
    property>
    <property name="mappings">
        <props>
            <prop key="hello.html">helloControllerprop>
            <prop key="login.html">loginActionprop>
            <prop key="userManager.html">userControllerprop>
            <prop key="userList.html">userListControllerprop>
        props>
    property>
bean>

 

这种方法和hibernate的OpenSessionInViewInterceptor是一样的
