Extjs + servlet + ext.ajax.request整合（亲测可用）

1.js代码

Ext.onReady(function(){
   
     Ext.Ajax.request({
     
         url:"AjaxServlet.do?name=里杂谈",
         //url:"AjaxServlet.do",
         method:"get",
         //params:{name:"xxx"},
         
         success:function(res,config){
             alert(config.url);
             alert(config.method);
             
             alert(res.responseText);
             //var json = res.responseText;
             var json = Ext.util.JSON.decode(res.responseText);
             
             alert("xx");
             Ext.MessageBox.alert("提示",json.author);
         },
         failure:function(){
             Ext.MessageBox.alert("result","请求失败")
             
         }
     });

 }) 
2.servlet
 
System.out.println("+++++");
         response.setContentType("text/html,charset=utf-8");
         PrintWriter out = response.getWriter();
         String name1 = request.getParameter("name");
         String name = "'"+name1+"'";
         System.out.println(name);
         Date date = new Date();
         //String time = date.toString();
         //String json = "{authon:" + name + ",time:" + time + "}";
         String json = "{author:"+name+"}";//转换成json。格式{name:"name"},而不是{name:name}
         
         out.println(json);
         
         System.out.println(json);
         out.flush();
         out.close();
