問題產生的原因

如何解決

<filter>
        <filter-name>openSessionInView</filter
 
-name>
        <filter class>org.springframework.orm.hibernate4.support.OpenSessionInViewFilter.class</filter-class>
    </filter>
    <filter-mapping>
        <filter-name>openSessionInView</filter-name>
        <url-pattern>/8*</url-pattern>
    </filter
 
-mapping>

如果使用的是Spring data 整合JPA的方法進行開發

    <filter>
        <filter-name>openSessionInView</filter-name>
        <filter-class>org.springframework.orm.jpa.support.OpenEntityManagerInViewFilter</filter-class>
    </filter>
    <filter-mapping
 
>
        <filter-name>openSessionInView</filter-name>
        <url-pattern>/*</url-pattern>
