SpringBoot 는 Fastjson 을 사용 하여 JSon 데 이 터 를 분석 하 는 방법

방법 1:
1.pom.xml 파일 에 의존 팩 추가

<dependency>
　　<groupId>com.alibaba</groupId>
　　<artifactId>fastjson</artifactId>
　　<version>1.2.15</version>
</dependency>

2.시작 파일 수정

package myshop;

import java.util.List;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.http.converter.HttpMessageConverter;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;

import com.alibaba.fastjson.serializer.SerializerFeature;
import com.alibaba.fastjson.support.config.FastJsonConfig;
import com.alibaba.fastjson.support.spring.FastJsonHttpMessageConverter;

@SpringBootApplication
public class App extends WebMvcConfigurerAdapter{
  @Override
  public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {
    // TODO Auto-generated method stub
    super.configureMessageConverters(converters);
    
    FastJsonHttpMessageConverter fastConverter = new FastJsonHttpMessageConverter();
    FastJsonConfig fastConfig = new FastJsonConfig();
    fastConfig.setSerializerFeatures(SerializerFeature.PrettyFormat);
    fastConverter.setFastJsonConfig(fastConfig);
    converters.add(fastConverter);
  }
  
  public static void main(String[] args) {
    // TODO Auto-generated method stub
    SpringApplication.run(App.class, args);
  }

}

3.실체 클래스 수정

package myshop.entity;

import java.util.Date;

import com.alibaba.fastjson.annotation.JSONField;

/**
 *    
 *
 */
public class User {
  private int id;
  private String username;
  private String password;
  @JSONField(format = "yyyy-MM-dd HH-mm")
  private Date createTime;
  /**
   *        remark  
   * serialize     
   */
  @JSONField(serialize = false)
  private String remark;
  public int getId() {
    return id;
  }
  public void setId(int id) {
    this.id = id;
  }
  public String getUsername() {
    return username;
  }
  public void setUsername(String username) {
    this.username = username;
  }
  public String getPassword() {
    return password;
  }
  public void setPassword(String password) {
    this.password = password;
  }
  public Date getCreateTime() {
    return createTime;
  }
  public void setCreateTime(Date createTime) {
    this.createTime = createTime;
  }
  public String getRemark() {
    return remark;
  }
  public void setRemark(String remark) {
    this.remark = remark;
  }
}

4.컨트롤 러 수정

package myshop.controller;

import java.util.Date;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import myshop.entity.User;

/**
 * @RestController = @Controller + @RequestBody
 *
 */
@RestController
public class HelloController {
  
  /**
   *       
   *
   */
  @RequestMapping("/hello")
  public String hello() {
    return "hello";
  }
  
  /**
   * SpringBoot       Jackson
   *
   */
  @RequestMapping("/getUser")
  public User gerUser()
  {
    User user = new User();
    user.setId(1);
    user.setUsername("  ");
    user.setPassword("123456");
    user.setCreateTime(new Date());
    //        
    user.setRemark("      ！");
    return user;
  }
}

5.프로젝트 시작,브 라 우 저 에 주소 입력:http://localhost:8080/getUser

방법 2:시작 클래스 를 제외 한 나머지 코드 는 모두 방법 과 같 습 니 다.

package myshop;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.web.HttpMessageConverters;
import org.springframework.context.annotation.Bean;
import org.springframework.http.converter.HttpMessageConverter;

import com.alibaba.fastjson.serializer.SerializerFeature;
import com.alibaba.fastjson.support.config.FastJsonConfig;
import com.alibaba.fastjson.support.spring.FastJsonHttpMessageConverter;

@SpringBootApplication
public class App {

  @Bean
  public HttpMessageConverters fastJsonHttpMessageConverter()
  {
    FastJsonHttpMessageConverter fastConverter = new FastJsonHttpMessageConverter();
    FastJsonConfig fastConfig = new FastJsonConfig();
    fastConfig.setSerializerFeatures(SerializerFeature.PrettyFormat);
    fastConverter.setFastJsonConfig(fastConfig);
    
    HttpMessageConverter<?> converts = fastConverter;
    return new HttpMessageConverters(converts);
  }
  
  public static void main(String[] args) {
    // TODO Auto-generated method stub
    SpringApplication.run(App.class, args);
  }

}
