SpringBoot 基本web开发demo

1.在创建的springboot项目中的pom.xml中导入Lombok的依赖

<dependency>
    <groupId>org.projectlombok</groupId>
    <artifactId>lombok</artifactId>
    <version>1.18.6</version>
</dependency>

2.安装Lombok插件

3.在主启动类的同级创建实体类的包，在包中创建实体类，并在实体类上使用Lombok

package com.hxy.bean;

import com.fasterxml.jackson.annotation.JsonFormat;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;

import java.util.Date;

@Data //替代了getter、setter和toString方法
@AllArgsConstructor //创建所有参数的有参构造函数
@NoArgsConstructor //创建无参构造函数
public class Car {
    private Integer id;
    private String name;
    private double price;

    @JsonFormat(pattern = "yyyy-MM-dd HH:mm:ss", timezone = "GMT+8")
    private Date createDate;
}

4.在在主启动类的同级创建控制层的包，并创建controller类

package com.hxy.controller;

import com.offcn.po.Car;
import org.springframework.cache.CacheManager;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.bind.annotation.RestController;

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

@RestController //替代了@ResponseBody和@Controller注解
@RequestMapping("/car")
public class CarController {

    @RequestMapping("/findone")
    public Car findOneCar(){
       Car car = new Car(1, "toyo", 1999.99F,new Date(),"13567890001");
        return car;
    }
}
