### 1.1、Lombok ###

简化JavaBean开发

<dependency>
                <groupId>org.projectlombok</groupId>
                <artifactId>lombok</artifactId>
            </dependency>
    
    
    idea中搜索安装lombok插件

===============================简化JavaBean开发===================================
    @NoArgsConstructor
    //@AllArgsConstructor
    @Data
    @ToString
    @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;
        }
    }

### 1.2、dev-tools ###

<dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-devtools</artifactId>
                <optional>true</optional>
            </dependency>
