java.lang.AssertionError和这两个实体是否相同？这是什么原因造成的？

使用

Assert.AssertEquals（）

方法测试DAO时，我遇到以下错误：

java.lang.AssertionError: expected: com.develop.test.data.entity.Rpoint<com.develop.test.data.entity.Rpoint@7668e5b5> but was: com.develop.test.data.entity.Rpoint<com.develop.test.data.entity.Rpoint@7668e5b5>

我一直在使用debug，两个实体都有相同的数据。这可能是由实体中的equals/HashCode实现引起的吗

编辑：添加了等于和哈希代码：

@Override
public boolean equals(Object instance) {
    if (instance == null)
        return false;

    if (!(instance instanceof Rpoint))
        return false;

    Rpoint o = (Rpoint) instance;
    return new EqualsBuilder().append(this.getId(), o.getId()).
            append(this.getCategory(), o.getCategory()).
            append(this.getDescription(), o.getDescription()).
            append(this.getPoints(), o.getPoints()).
            append(this.getActive(), o.getActive()).
            isEquals();
}

@Override
public int hashCode() {
    return new HashCodeBuilder(23, 25).append(this.getId()).
            append(this.getCategory()).
            append(this.getDescription()).
            append(this.getPoints()).
            append(this.getActive()).
            toHashCode();
}

是的，如果

equals

实现得不好，即使使用相同的引用，它也会返回false，这肯定会导致失败。请注意，这不仅仅是对象内的数据相同的情况，而且诊断结果表明两侧都是相同的对象：

expected [...].Rpoint<com.develop.test.data.entity.Rpoint@7668e5b5>
but was: [...].Rpoint<com.develop.test.data.entity.Rpoint@7668e5b5>

应为[…].Rpoint
但是是：[……]Rpoint

7668e5b5实际上不应该被视为对象标识，但它在这里非常具有启发性

请显示您正在使用的

equals

方法。

Rpoint的equals/hashCode是什么样子的？我想我在类别equals

中发现了错误，如果（！（类别实例instanceof category））返回false已设置为其他实体。我修复了这个，现在它工作了。我讨厌复制/粘贴的人：(
expected [...].Rpoint<com.develop.test.data.entity.Rpoint@7668e5b5>
but was: [...].Rpoint<com.develop.test.data.entity.Rpoint@7668e5b5>
