xml配置

java代码

访问action返回数据报错

No result defined for action com.test.action.UserManageAction and result input

单独访问acion名，得到

{"allUserInfo":"success","rows":[{"userAccount":"a","userAnswer":null,"userIsadmin":null,"userName":null,"userPasswd":null,"userQuestion":null},{"userAccount":"aa","userAnswer":null,"userIsadmin":null,"userName":null,"userPasswd":null,"userQuestion":null},{"userAccount":"admin","userAnswer":"北京","userIsadmin":"Y","userName":"管理员","userPasswd":"admin","userQuestion":"00"},{"userAccount":"b","userAnswer":null,"userIsadmin":null,"userName":null,"userPasswd":null,"userQuestion":null},{"userAccount":"bb","userAnswer":null,"userIsadmin":null,"userName":null,"userPasswd":null,"userQuestion":null},{"userAccount":"bbb","userAnswer":null,"userIsadmin":null,"userName":null,"userPasswd":null,"userQuestion":null},{"userAccount":"c","userAnswer":null,"userIsadmin":null,"userName":null,"userPasswd":null,"userQuestion":null},{"userAccount":"cc","userAnswer":null,"userIsadmin":null,"userName":null,"userPasswd":null,"userQuestion":null},{"userAccount":"ccc","userAnswer":null,"userIsadmin":null,"userName":null,"userPasswd":null,"userQuestion":null},{"userAccount":"d","userAnswer":null,"userIsadmin":null,"userName":null,"userPasswd":null,"userQuestion":null},{"userAccount":"dd","userAnswer":null,"userIsadmin":null,"userName":null,"userPasswd":null,"userQuestion":null},{"userAccount":"ddd","userAnswer":null,"userIsadmin":null,"userName":null,"userPasswd":null,"userQuestion":null},{"userAccount":"f","userAnswer":null,"userIsadmin":null,"userName":null,"userPasswd":null,"userQuestion":null},}],"total":15}

数据正常

将数据保存在json格式文件中访问，可以成功，但为什么这样就不能访问了。报错原因很明显了，没有配置input结果，

其实我们已经很清楚，返回的数据是正确的，但在后台，由于类型不匹配或者本身将结果集看错字符串，无法解析，所以报错。

当我们明确知道结果的时候可以将配置文件修改如下：

也就是说，无论能否解析，我们都要获取得到的数据信息并返回给前台。这样前台得到数据就可以通过easyui的规则解析到datagrid中，正常显示。
