Spring 4 + hibernate 5 + Structs2

struts2-json-plugin版本问题导致org.apache.struts2.json.JSONResult找不到。

之前是2.8的版本。

        <dependency>            <groupId>org.apache.struts</groupId>            <artifactId>struts2-json-plugin</artifactId>            <version>2.3.20.3</version>        </dependency>

Structs前台显示不了json数据

在 StrutsPrepareAndExecuteFilter 前加入

<filter>        <filter-name>openSessionInViewFilter</filter-name>        <filter-class>org.springframework.orm.hibernate5.support.OpenSessionInViewFilter</filter-class>    </filter>    <filter-mapping>        <filter-name>openSessionInViewFilter</filter-name>        <url-pattern>/*</url-pattern>    </filter-mapping>

具体解释：http://blog.csdn.net/a19881029/article/details/7916702

ssh maven 有两个 javassist包
