1. Lombok

• 简化JavaBean开发
• idea中搜索安装lombok插件
• 同时导入lombok依赖 ```xml

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

①@Data可以自动为bean类创建get、set和toString方法<br />②@NoArgsConstructor可以自动为bean类创建无参构造器<br />③@AllArgsConstructor可以自动为bean类创建全参构造器
```java
===============================简化JavaBean开发===================================
@NoArgsConstructor
//@AllArgsConstructor
@Data
@EqualsAndHashCode
public class User {

    private String name;
    private Integer age;

    private Pet pet;

    public User(String name,Integer age){
        this.name = name;
        this.age = age;
    }


}



================================简化日志开发===================================
@Slf4j
@RestController
public class HelloController {
    @RequestMapping("/hello")
    public String handle01(@RequestParam("name") String name){

        log.info("请求进来了....");

        return "Hello, Spring Boot 2!"+"你好："+name;
    }
}
