1.在项目中加入struts2-dojo-plugin-2.1.8.jar

2.在jsp页面中加入<%@ taglib prefix="sx" uri="/struts-dojo-tags"%>

在<head><sx:head /></head>

<sx:tree rootNode="root" nodeIdProperty="id" nodeTitleProperty="name" childCollectionProperty="childrens"
  showRootGrid="true" showGrid="true" id="nodeId">
  </sx:tree>

3.在web.xml中的strus2配置如下：

<filter>
  <filter-name>struts2</filter-name>
  <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
</filter>

<filter-mapping>
  <filter-name>struts2</filter-name>
  <url-pattern>/*</url-pattern>
</filter-mapping>
<filter-mapping>
若配置如下：

<filter>
  <filter-name>struts2</filter-name>
  <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
</filter>

<filter-mapping>
  <filter-name>struts2</filter-name>
  <url-pattern>*.jsp</url-pattern>
</filter-mapping>
<filter-mapping>
  <filter-name>struts2</filter-name>
  <url-pattern>*.action</url-pattern>
</filter-mapping>

则不能过滤js文件了，会报错，可以加

<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>*.js</url-pattern>
</filter-mapping>

或者直接写成如下

filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
