下面是后台Action的一部分代码

@Autowired

    private UserService userService;

    public String getAllUser(){

        jsonMap = new HashMap<String, Object>();

        jsonMap.put("postStatus",);//代表没有异常，成功生成数据

      //  jsonMap.put("message","恭喜!数据成功生成（给前端工程师看）");

        List<User> userList = userService.getAllUser();

        jsonMap.put("userList",userList);

        return "jsonOK";

    }

Struts配置

<struts>

    <constant name="struts.objectFactory" value="spring"></constant>

    <package name="myPackage" extends="struts-default,json-default">

        <action name="userAction_*" class="userAction" method="{1}">

            <result type="json" name="jsonOK">

                <param name="root">jsonMap</param>

            </result>

            <allowed-methods>getAllUser</allowed-methods>

        </action>

    </package>

</struts>
