hibernate中实现判断属性值是否相同
附截图
public class User {
private int id;private String username;
private String password;
private int age;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
@Override
public boolean equals(Object otherObject) {
// 判断内存地址是否相同
if (this == otherObject) {
return true;
} else {
// 判断是否为User对象
if (!(otherObject instanceof User))
return false;
}
User user = (User) otherObject;
// 判断各个属性值是否相同
if (id == user.id && username.equals(user.username) && password.equals(user.password) && age == user.age) {
return true;
}
return false;
}
@Override
public int hashCode() {
int result;
result = username.hashCode() + password.hashCode();
result = 29 * age + result;
return result;
}
}
}
