Xml 使用jaxb2 maven插件版本2.2生成Equals和HashCode

我们使用jaxb2 maven插件（版本2.2），并为每个JAXBO对象生成equal和hashCode方法。 我们已经读取了binding.xjb文件来配置任何东西

有没有办法生成这种方法

如果我尝试添加参数-Xequals-XhashCode，我会得到以下异常：unbekanner参数-Xequals-XhashCode

配置：

<configuration> <arguments>-Xequals -XhashCode</arguments> </configuration>

-Xequals-XhashCode

---

谢谢大家!

您可以使用插件生成

hashCode

和

equals

：

我个人更喜欢生成“战略性”方法的

-Xequals

和

-XhashCode

。“策略”在某种意义上，这些方法使用传递的策略进行相等或哈希代码计算：

public boolean equals(Object object) {
    final EqualsStrategy2 strategy = JAXBEqualsStrategy.INSTANCE2;
    return equals(null, null, object, strategy);
}

public boolean equals(ObjectLocator thisLocator, ObjectLocator thatLocator, Object object, EqualsStrategy2 strategy) {
    if ((object == null)||(this.getClass()!= object.getClass())) {
        return false;
    }
    if (this == object) {
        return true;
    }
    final PurchaseOrderType that = ((PurchaseOrderType) object);
    {
        USAddress lhsShipTo;
        lhsShipTo = this.getShipTo();
        USAddress rhsShipTo;
        rhsShipTo = that.getShipTo();
        if (!strategy.equals(LocatorUtils.property(thisLocator, "shipTo", lhsShipTo), LocatorUtils.property(thatLocator, "shipTo", rhsShipTo), lhsShipTo, rhsShipTo, (this.shipTo!= null), (that.shipTo!= null))) {
            return false;
        }
    }
    // ...
    return true;
}

public int hashCode() {
    final HashCodeStrategy2 strategy = JAXBHashCodeStrategy.INSTANCE2;
    return this.hashCode(null, strategy);
}

public int hashCode(ObjectLocator locator, HashCodeStrategy2 strategy) {
    int currentHashCode = 1;
    {
        USAddress theShipTo;
        theShipTo = this.getShipTo();
        currentHashCode = strategy.hashCode(LocatorUtils.property(locator, "shipTo", theShipTo), currentHashCode, theShipTo, (this.shipTo!= null));
    }
    // ...
    return currentHashCode;
}

策略方法非常酷，因为您可以自定义相等/哈希代码计算-例如，结构完全不同的日志。这是以运行时依赖性为代价的

免责声明：我是该问题的作者。

此问题解决方案的可能副本是使用参数：-Xequals-XhashCode如果我尝试此操作，我会得到以下异常：unbekanner参数-Xequals-XhashCode我认为这两个问题之间的区别在于版本。可能在这个问题中，重复的解决方案是使用参数：-Xequals-XhashCode如果我尝试这个，我会得到以下异常：unbekanner参数-Xequals-XhashCode我认为这两个问题的区别在于版本。小更新：在版本1.11.1中，参数被重命名为

-Xequals-XhashCode

@petronius没有版本1.11.1-它是错误发布的。官方版本是0.11.1。@petronius也没有重命名参数。我不明白，maven repo 1.11.1确实存在：（以及1.11.1-错误发布）。为了使它工作，我必须编写

-Xequals

和

-XhashCode

，因为使用

-XsimpleEquals

我得到了错误：
