@JSON(serialize=false)是注解排除不需要加载的属性,找到它的get方法,解决no-session问题.

在hibernate使用

<filter>
<filter-name>OpenSession</filter-name>
<filter-class>org.springframework.orm.hibernate3.support.OpenSessionInViewFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>OpenSession</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

在Spring data jpa使用

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