04、使用Lombok简化开发

4.1、Lombok

简化JavaBean开发

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

===============================简化JavaBean开发===================================
@NoArgsConstructor //无参构造方法
@AllArgsConstructor //有参构造方法
@Data //省略set get方法
@ToString //toString
@EqualsAndHashCode //重写equals
//将该组件放入容器中
//@Component
//@ConfigurationProperties(prefix = "student")
public class Student {
    private String stuName;
    private String stuNumber;
}
==================测试===================
@RestController
public class HelloController {
    @Autowired
    private Car car;
//    @Autowired
//    private Student student;
//
//    @RequestMapping("/student")
//    private Student getStudent(){
//        return student;
//    }
    @RequestMapping("/student2")
    private Student getStudent() {
        Student student = new Student();
        student.setStuName("hezzz")
        ;student.setStuNumber("1111");
        return student;
    }
}
