java 判断 Object 对象类型 java判断对象类型是否一致

Java中如何判断两个对象的属性是否一致(方法1)

需求:前端编辑对象后,将对象传给后端.后端需要判断是否修改了某一个属性.比如前端传过来的对象只修改了description属性,那么我就不算他修改.后端不做更新或做其他处理.
1.依赖

<dependency>
            <groupId>com.github.colincatsu</groupId>
            <artifactId>fast-object-diff</artifactId>
            <version>1.1</version>
    </dependency>

2.实体类

// User类
@Data
@AllArgsConstructor
@NoArgsConstructor
public class User {
    @DiffLog(name = "id")
    private int id;
    @DiffLog(name = "name")
    private String name;
    @DiffLog(name = "age")
    private int age;
    @DiffLog(name = "students")
    private List<Student> students;
}

// Student类
@Data
@AllArgsConstructor
@NoArgsConstructor
public class Student {
    @DiffLogKey(name = "files id")
    @DiffLog(name = "other")
    private int id;
    @DiffLog(name = "other")
    private String username;
    @DiffLog(name = "other")
    private String password;
}

// 测试类
@SpringBootTest
@RunWith(SpringRunner.class)
public class FastObjectDiffTest {

    @Test
    public void test1() throws Exception {

        Student student = new Student(1,"天数","123456");
        List<Student> students = new ArrayList<>();
        students.add(student);

        Student student2 = new Student(1,"天数","666666");
        List<Student> students2 = new ArrayList<>();
        students2.add(student2);

        User user1 = new User(1,"zhangsan",1,students);
        User user2 = new User(2,"lisi",2,students2);
        
        List<DiffWapper> diffWappers = AbstractObjectDiff.generateDiff(user1, user2);
        System.out.println(diffWappers.size());
    }
}
