SpringBoot basic web development demo method

1. Import Lombok dependencies in pom.xml in the created springboot project

<dependency>
  <groupid>org.projectlombok</groupid>
  <artifactid>lombok</artifactid>
  <version>1.18.6</version>
</dependency>

2. Install the Lombok plug-in

3. Create a package of the entity class at the same level as the main startup class, create the entity class in the package, and use Lombok on the entity class

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. Create a control layer package at the same level as the main startup class, and create a controller class

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;
  }
}
