前提:已搭建好环境

1.建立Controller

1 package com.ice.controller; 2  3 import com.ice.model.Person; 4 import org.springframework.stereotype.Controller; 5 import org.springframework.web.bind.annotation.RequestMapping; 6 import org.springframework.web.bind.annotation.ResponseBody; 7  8 @RequestMapping("/person") 9 @Controller10 public class PersonController {11     @RequestMapping("/get")12     @ResponseBody13     public Person get(){14         Person person=new Person();15         person.setAge(18);16         person.setName("ice");17         return person;18     }19 }

访问后报错,如下

Type Exception Report

Message No converter found for return value of type: class com.ice.model.Person

Description The server encountered an unexpected condition that prevented it from fulfilling the request.

Exception

    org.springframework.http.converter.HttpMessageNotWritableException: No converter found for return value of type: class com.ice.model.Person

    org.springframework.web.servlet.mvc.method.annotation.AbstractMessageConverterMethodProcessor.writeWithMessageConverters(AbstractMessageConverterMethodProcessor.java:226)

2.解决方法

引入依赖

             
                 
      
       com.alibaba
                  
      
       fastjson
                  
      
       1.2.47
              
     

修改spring-configure.xml

1 
     
       2         
      
        3             
        4             
        5             
       
         6                 
        
          7                     
         
           8                         
          
           text/html;charset=UTF-8
           9                         
          
           application/json;charset=UTF-8
          10                     
         11                 
        12             
       13         
      14     
     

 

3.重新运行ok

{"age":18,"name":"ice"}
