我正在尝试从XSD文件生成包含toString，equals和hashCode方法的Java类。我得到了串工作，但我无法弄清楚如何让CXF插件生成equals和hashCode方法。
这是我的XSD文件：
<?xml version="1.0" encoding="utf-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" targetNamespace="http://www.example.com/messagedefinitions"
xmlns="http://www.example.com/messagedefinitions">

<xs:complexType>
<xs:sequence>
<xs:element name="status" type="Status"/>
<xs:element name="id" type="Identifier"/>
</xs:sequence>
</xs:complexType>
</xs:element>
<xs:simpleType name="Status">
<xs:restriction base="xs:string">
<xs:maxLength value="4"/>
</xs:restriction>
</xs:simpleType>
<xs:simpleType name="Identifier">
<xs:restriction base="xs:int"/>
</xs:simpleType>

如果我取消注释Xequals的注释掉的行，我会收到此错误：
[错误]无法在项目xsd-demo上执行目标org.apache.cxf：cxf-xjc-plugin：2.6.1：xsdtojava（generate-sources）：无法下载扩展工件：请求的下载不存在。找不到工件org.apache.cxf.xjcplugins：cxf-xjc-Xequals：jar：2.6.1 in central（http://repo1.maven.org/maven2）
很好，我意识到工件不存在，但我不知道如何配置CXF插件来生成equals和hashCode方法。你知道我如何配置CXF插件来生成equals和hashCode方法吗？提前感谢您的帮助。

我无法从cxf-xjc-plugin中获取XML模式文件中的equals和hashCode方法。我放弃了cxf-xjc-plugin，转而使用maven-jaxb2-plugin。这是我使用的插件配置：

阅读此HOWTO之后，我就这样开始工作了：

<!-- The generated equals and hashCode methods require some runtime libraries. -->
<dependency>
<groupId>org.jvnet.jaxb2_commons</groupId>
<artifactId>jaxb2-basics-runtime</artifactId>
</dependency>
</dependencies>
不幸的是，对我来说，使用jvnet jaxws-maven-plugin不是一个选项，因为我们的WSDL文件是由第三方提供给我们的，并且它们存在问题（例如soap:body内的wsdl:fault元素导致标准插件窒息的元素。
答案 2 :(得分：0)
你肯定来不及......但是......
我设法使用org.jvnet.jaxb2_commons生成哈希码，并使用插件cxf-xjc-plugin（如问题所示）等于：jaxb2-basics：0.7.0
你需要org.jvnet.jaxb2_commons：jaxb2-basics：0.7.0来生成方法（equals，hashcode）和org.jvnet.jaxb2_commons：jaxb2-basics-runtime：0.7.0用于编译依赖
使用antrun很难看但我需要它来为我的剧集生成一个目录 build-helper-maven-plugin的使用是将生成的目录添加到eclipse中的classpath 我使用绑定文件（必要时更改）
