基础生成

  @Getter@Setter@EqualsAndHashCode(of = {"name","sex","age"})  @ToString(of = {"name","sex","age"})private static class Student01{private String name;private int age;private Byte sex;}

构造函数

   @NoArgsConstructor(access = AccessLevel.PRIVATE)       //无参构造函数 access设置权限@AllArgsConstructor                //全参构造函数private static class Student02{private String name;private int age;}

建造者

    @Data //@Getter @Setter @RequiredArgsConstructor @ToString @EqualsAndHashCode@Value@Accessors(chain = true, fluent = true)@Builderprivate static class Student03{private String name;private int age;@Singular("addHobby")private List<String> hobby;public static void main(String[] args) {Student03 student03=Student03.builder().name("hello").age(10).addHobby("hobby1").addHobby("hobby2").build();System.out.println(student03);}}

     @SneakyThrows    //异常处理@Synchronized    //加锁处理  public void shitHappens(){//   自动关闭资源@Cleanup FileOutputStream instream=new FileOutputStream(in);//   instream.close();Thread.sleep(1000);}
