</project>

2.实体类User

package org.javaboy.json.bean;

//import com.fasterxml.jackson.annotation.JsonFormat;

import java.util.Date;

public class User {
    private Integer id;
    private String name;
    private String address;

    private Date birthday;

    public Integer getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getAddress() {
        return address;
    }

    public void setAddress(String address) {
        this.address = address;
    }

    public Date getBirthday() {
        return birthday;
    }

    public void setBirthday(Date birthday) {
        this.birthday = birthday;
    }

    @Override
    public String toString() {
        return "User{" +
                "id=" + id +
                ", name='" + name + '\'' +
                ", address='" + address + '\'' +
                ", birthday=" + birthday +
                '}';
    }
}

3.控制类：UserContoller

package org.javaboy.json.controller;

import org.javaboy.json.bean.User;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.bind.annotation.RestController;

import java.util.ArrayList;
import java.util.Date;
import java.util.List;

//@Controller
@RestController
public class UserContoller {

//    @ResponseBody
    @GetMapping("/user")
    public List<User> getAllUsr(){
        List<User> users = new ArrayList<>();
        for (int i = 0; i < 10; i++) {
            User user = new User();
            user.setAddress("www.javaboy.org>>" + i);
            user.setName("javaboy>>" + i);
            user.setId(i);
            user.setBirthday(new Date());
            users.add(user);
        }
        return users;
    }
}

4.配置类：WebMvcConfig

package org.javaboy.json.config;


import com.alibaba.fastjson.support.config.FastJsonConfig;
import com.alibaba.fastjson.support.spring.FastJsonHttpMessageConverter;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.http.converter.json.GsonHttpMessageConverter;

import java.text.SimpleDateFormat;

@Configuration
public class WebMvcConfig {
    @Bean
    FastJsonHttpMessageConverter fastJsonHttpMessageConverter() {
        FastJsonHttpMessageConverter converter = new FastJsonHttpMessageConverter();
        FastJsonConfig config = new FastJsonConfig();
        config.setDateFormat("yyyy-MM-dd");
        converter.setFastJsonConfig(config);
        return converter;
    }
}

5.启动工程
访问：http://localhost:8080/user
