方法一：
1.在pom.xml文件下添加依賴包
<dependency> <groupId>com.alibaba</groupId> <artifactId>fastjson</artifactId> <version>1.2.15</version> </dependency>
2.修改啟動文件
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.修改實體類
package myshop.entity;
import java.util.Date;
import com.alibaba.fastjson.annotation.JSONField;
/**
* 用戶類
*
*/
public class User {
private int id;
private String username;
private String password;
@JSONField(format = "yyyy-MM-dd HH-mm")
private Date createTime;
/**
* 如果不希望返回remark信息
* serialize是否序列化
*/
@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.修改控制器
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 {
/**
* 建立請求映射
*
*/
@RequestMapping("/hello")
public String hello() {
return "hello";
}
/**
* SpringBoot默認的解析框架Jackson
*
*/
@RequestMapping("/getUser")
public User gerUser()
{
User user = new User();
user.setId(1);
user.setUsername("天恒");
user.setPassword("123456");
user.setCreateTime(new Date());
//此信息不會被返回
user.setRemark("這是備注信息！");
return user;
}
}
5.啟動項目，在瀏覽器輸入地址：http://localhost:8080/getUser
方法二：除了啟動類，其余代碼都和方法一一樣
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);
}
}
