首先最简单的来说：
引入struts2-json-plugin jar包
<package name="myjson" extends="json-default"> <action name="getJson" class="userAction" method="getJson"> <result type="json"> <param name="root">jsonResult</param> </result> </action> </package>
action 中的方法：
public String getJson(){
jsonResult = new HashMap<String, Object>();
User user = new User();
user.setName("username");
user.setId(110);
user.setPassword("password");
jsonResult.put("user", user);
return SUCCESS;
}
页面：
<script type="text/javascript">
function getJson(){
$.getJSON("getJson.action", function(json){
alert(json.user);
});
}
</script>
实现的大概功能很简单：输入关键字查询，结果关键字红色显示，批量删除，分页，等等，前台通过ajax获取json数据，然后显示。可以每页显示25，50,75条数据，可以直接跳转到指定页。。。
页面通过jquery的 post方法，设置返回值类型为json，struts2里面，在struts.xml中引入json-default,即可引入result的type为json的类型，这样返回给前台的数据就是json格式，里面封装了action里面可以通过get方法获取到的属性，如果不希望某属性被添加到json里面，可以通过@JSON(serialize=false)在它的get方法上注解一下就好了。。。
首先是 web.xml：
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.4"
xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
<listener>
<listener-class>

</listener-class>
</listener>
<filter>

<filter-mapping>
<filter-name>struts2Filter</filter-name>
<url-pattern>/*</url-pattern>
<dispatcher>REQUEST</dispatcher>
<dispatcher>FORWARD</dispatcher>
</filter-mapping>
</web-app>
web.xml里面没有什么东东，只有一个启动spring的监听器和struts2的filter
接下来是applicationcontext.xml：
<?xml version="1.0" encoding="UTF-8"?>

都是很简单的东东，自己做测试的东东嘛。。。就图个简单
下面是struts.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN"
"http://struts.apache.org/dtds/struts-2.1.dtd">
<struts>
<!-- 开发阶段设置 -->
<constant name="struts.devMode" value="true" />
<constant name="struts.serve.static.browserCache " value="false" />

<package name="" extends="json-default">
<action name="testAction" class="action.MyAction" method="method1">
<result>/page/MyJsp.jsp</result>
</action>
<action name="getJson" class="action.MyAction" method="getJson">
<result type="json"></result>
</action>
<action name="deleteRecord" class="action.MyAction" method="deleteRecord">
<result type="chain">getJson</result>
</action>
</package>
</struts>
这里面注意是
<package name="" extends="json-default"> <!-- 这里继承的json-default包 -->
<action name="getJson" class="action.MyAction" method="getJson"> <result type="json"></result> <!-- 这里是json的结果类型 --> </action>
所以需要额外引入 struts2-json-plugin-2.3.12.jar 这个jar包。。。
下面是我的action类：

}

//如果要查询的页数大于总页数，则将查询页数改为总页数
if(queryCondition.getPageNum()>queryCondition.getTotalNum()){
queryCondition.setPageNum(queryCondition.getTotalNum());
}
users = userService.getUsersByUsernameOrRealname(queryCondition.getName(),queryCondition.getPageNum(),queryCondition.getSize(),
