Ext_json_Struts_Json_ext之间的转换

来源：互联网发布：linux怎么复制目录编辑：程序博客网时间：2024/05/21 22:37

网络牛人写的我进行处理一下：

strusts.xml 配置

<package name="ext_json_struts2_json_ext" extends="json-default">
                  //这里一定要继承json-default否则下面的type为非法
       <interceptors>
           <interceptor-stackname="myDefaultStack">
               <interceptor-ref name="json"/>
               <interceptor-ref name="defaultStack"/>
            </interceptor-stack>
      </interceptors>
      <default-interceptor-refname="myDefaultStack"/>

       <actionname="updateTaskUser" class="adminDefaultViewAction" method="updateTaskUser">
           <result type="json">   // 这里要就行返回对象指定
               <param name="root">optionResult</param>//这里是返回
           </result>
       </action>
   </package>

jsp页面的js

Ext.define('Candidates', {
          extend:'Ext.data.Model',
          fields: [
                    {name: 'key',    type: 'string'},
                   {name: 'name', type: 'string'}
         ]
});
//定义数据模型

var data = {
    users: [
        {
            key:'jack1',
            name:'jack1'
        },
        {
            key: 'jack2,
            name:'jack2'
        }
    ]
};

//创建数据源

var candidatesStore = Ext.create('Ext.data.Store', {
    autoLoad: true,
    model: 'Candidates',
    data : data,
    proxy: {
        type: 'memory',
        reader: {
            type:'json',
            root:'users'
        }
    }
});

//这里是数据源和数据模型通过代理转化成一个库

var length = candidatesStore.getCount( );//得到该库的长度以便在js中转成json对象

var jsonCandidates= [];//json是一个数组类型所以定义一个数组

for(var j=0;j< length;j++){
   jsonCandidates.push({
       key:candidatesStore.getAt(j).get('key'),
       name:candidatesStore.getAt(j).get('name'),
   });
}//转换成json对象

Ext.Ajax.request({
url : '<%=rootPath%>/updateTaskUser.action',
method:'post',

jsonData:{

username: 'jack',//username ,指明bean中的字段

processInstanceUUID: 'test',//processUUID,指明bean中的字段

changeCandidates :jsonCandidates //要进行提交的json

} ,

   success : function(response, options) {
   //     popWindow.close();//返回进行关闭
   }
}

javabean
public class Candidates {
   private String name;
   private String key;
   public String getKey() {
       return key;
   }
   public void setKey(String key) {
       this.key = key;
   }

   public String getName() {
       return name;
   }
   public void setName(String name) {
       this.name = name;
   }
}

Action
public class TestAction extends ActionSupport {
   List<Candidates> changeCandidates;
   String username ;
   String processInstanceUUID;

   public String getUsername() {
       return username;
   }

   public void setUsername(String username) {
       this.username = username;
   }

   public List<Candidates> getChangeCandidates() {
       return changeCandidates;
   }

   public void setChangeCandidates(List<Candidates>changeCandidates) {
       this.changeCandidates = changeCandidates;
   }
   public String getProcessInstanceUUID() {
       return processInstanceUUID;
   }

   public void setProcessInstanceUUID(StringprocessInstanceUUID) {
       this.processInstanceUUID =processInstanceUUID;
   }

//进行action方法处理
   public String updateTaskUser() {
       optionResult =xxxService.xxxxx(changeCandidates,username, processInstanceUUID);
       return SUCCESS;
   }
}
