一、配置pom.xml文檔html

 1 <?xml version="1.0" encoding="UTF-8"?>

二、書寫測試代碼pojo（實體類）java

 1 package com.easytest;
 2 
 3 import com.alibaba.fastjson.annotation.JSONField;
 4 
 5 import java.util.Date;
 6 
 7 /**
 8  * Created by liuya on 2018-01-17.
 9  */
10 public class UserPoJo
11 {
12     private int userId;
13     private String userName;
14     @JSONField(format="yyyy-MM-dd HH:mm:ss")
15     private Date createTime;
16 
17     public Date getCreateTime() {
18         return createTime;
19     }
20 
21     public void setCreateTime(Date createTime) {
22         this.createTime = createTime;
23     }
24 
25     public int getUserId() {
26         return userId;
27     }
28 
29     public void setUserId(int userId) {
30         this.userId = userId;
31     }
32 
33     public String getUserName() {
34         return userName;
35     }
36 
37     public void setUserName(String userName) {
38         this.userName = userName;
39     }
40 
41     @Override
42     public String toString() {
43         return "UserPoJo{" +
44                 "userId=" + userId +
45                 ", userName='" + userName + '\'' +
46                 ", createTime=" + createTime +
47                 '}';
48     }
49 }

三、書寫測試服務器web

 1 package com.easytest;
 2 
 3 import com.alibaba.fastjson.serializer.SerializerFeature;
 4 import com.alibaba.fastjson.support.config.FastJsonConfig;
 5 import com.alibaba.fastjson.support.spring.FastJsonHttpMessageConverter;
 6 import org.springframework.boot.SpringApplication;
 7 import org.springframework.boot.autoconfigure.SpringBootApplication;
 8 import org.springframework.http.MediaType;
 9 import org.springframework.http.converter.HttpMessageConverter;
10 import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
11 
12 import java.util.ArrayList;
13 import java.util.List;
14 
15 @SpringBootApplication
16 public class RebushuApplication extends WebMvcConfigurerAdapter {
17 
18     /**
19      //     * 在這裏咱們使用 @Bean注入 fastJsonHttpMessageConvert
20      //     * @return
21      //     */
22     @Override
23     public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {
24 
25         // 一、須要先定義一個 convert 轉換消息的對象;
26         FastJsonHttpMessageConverter fastConverter = new FastJsonHttpMessageConverter();
27 
28         //二、添加fastJson 的配置信息，好比：是否要格式化返回的json數據;
29         FastJsonConfig fastJsonConfig = new FastJsonConfig();
30         fastJsonConfig.setSerializerFeatures(SerializerFeature.PrettyFormat);
31 
32         //處理中文亂碼
33         List<MediaType> fastMediaTypes = new ArrayList<>();
34         fastMediaTypes.add(MediaType.APPLICATION_JSON_UTF8);
35         fastConverter.setSupportedMediaTypes(fastMediaTypes);
36 
37         //三、在convert中添加配置信息.
38         fastConverter.setFastJsonConfig(fastJsonConfig);
39 
40         HttpMessageConverter<?> converter = fastConverter;
41         converters.add(fastConverter);
42     }
43 
44     public static void main(String[] args) {
45         SpringApplication.run(RebushuApplication.class, args);
46     }
47 }

四、書寫controller代碼spring

 1 package com.easytest;
 2 
 3 import org.springframework.web.bind.annotation.RequestMapping;
 4 import org.springframework.web.bind.annotation.RestController;
 5 
 6 import java.util.Date;
 7 
 8 /**
 9  * Created by liuya on 2018-01-16.
10  *
11  *  測試用的一個helloworld例子
12  */
13 
14 
15 @RestController
16 public class ControllerJson {
17 
18     @RequestMapping("user2")
19     public UserPoJo hello(){
20         //實體類賦值
21         UserPoJo userPoJo  = new UserPoJo();
22         userPoJo.setUserId(111);
23         userPoJo.setUserName("王小二");
24         userPoJo.setCreateTime(new Date());
25         //返回實體類
26         return userPoJo;
27     }
28 }
