Argument(s) are different! Wanted:-优快云博客

本文介绍了解决使用Mockito时遇到的错误，重点在于如何正确重写equals()和hashCode()方法来确保对象比较的一致性。通过使用Apache Commons Lang3库简化了这一过程。

概述：

用Mocktio时报错，很郁闷

、

看看明明是相等的，呵呵，你以为相等就相等，不用人的思维去思考电脑，对象相不相等取决于equals() 和 hashCode()

如果你不重新这个两个方法，创建两个相同值的对象，其实也是不相等的。

现在去重写这个两个方法

package com.jack.data;

import org.apache.commons.lang3.builder.EqualsBuilder;
import org.apache.commons.lang3.builder.HashCodeBuilder;

public class Spitter {

	private long l;
	private String firstName;
	private String lastName;
	private String username;
	private String password;
	
	public Spitter() {
		super();
		// TODO Auto-generated constructor stub
	}
	public Spitter(String firstName, String lastName, String username, String password) {
		this.firstName = firstName;
		this.lastName = lastName;
		this.username = username;
		this.password = password;
	}
	public Spitter(long l, String firstName, String lastName, String username, String password) {
		this.l = l;
		this.firstName = firstName;
		this.lastName = lastName;
		this.username = username;
		this.password = password;
	}
	public String getFirstName() {
		return firstName;
	}
	public String getLastName() {
		return lastName;
	}
	public String getUsername() {
		return username;
	}
	public String getPassword() {
		return password;
	}
	public void setFirstName(String firstName) {
		this.firstName = firstName;
	}
	public void setLastName(String lastName) {
		this.lastName = lastName;
	}
	public void setUsername(String username) {
		this.username = username;
	}
	public void setPassword(String password) {
		this.password = password;
	}
	public long getL() {
		return l;
	}
	public void setL(long l) {
		this.l = l;
	}
	
	@Override
	public boolean equals(Object obj) {
		
		return EqualsBuilder.reflectionEquals(this, obj, "firstName", "lastName");
	}
	@Override
	public int hashCode() {
		
		return HashCodeBuilder.reflectionHashCode(this, "firstName", "lastName");
	}
	@Override
	public String toString() {
		return "Spitter [l=" + l + ", firstName=" + firstName + ", lastName=" + lastName + ", username=" + username
				+ ", password=" + password + "]";
	}
	
	
	
}

总结：采用Apache的lang3进行重写这里两个方法，如果你不想自己写出现意想不到的情况，就引用jar包lang3
