java JAXB 生成错误的类

JAXB generates faulty classes

提问by Siegfried Storr

after generating some classes from a xsd file, the classes are faulty. a @xmlElementRef is used with required="false" and that attribute is not allowed. My .xsd I'm using:

从 xsd 文件生成一些类后，这些类有问题。@xmlElementRef 与 required="false" 一起使用，该属性是不允许的。我正在使用的 .xsd：

How can i get XmlElement instead of XmlElementRef? What do i have to change in the xsd? The xsd is an extract from a wsdl and i want to use the resulting classes to call a webservice.

我怎样才能得到 XmlElement 而不是 XmlElementRef？我必须在 xsd 中更改什么？xsd 是 wsdl 的摘录，我想使用生成的类来调用 web 服务。

OK, some mor infos here, can't answer my own question...

好的，这里有一些更多信息，无法回答我自己的问题...

I'm working with STS and Java6. in my build.xml is coded

我正在使用 STS 和 Java6。在我的 build.xml 中被编码

<!-- JAXB-->
<taskdef name="xjc" classname="com.sun.tools.xjc.XJCTask">
    <classpath>

    </classpath>
</taskdef>

        <schema dir="conf/webapp/WEB-INF/schema" includes="*.xsd" />
        <binding dir="resources" includes="*.xjb" />
    </xjc>
</target>

My binding.xjb looks like

我的 binding.xjb 看起来像

<jxb:bindings version="1.0"

    <jxb:bindings node="/s:schema/s:element[@name='AccountStatus']">
        <jxb:class name="AccountStatusRequest"/>
    </jxb:bindings>
</jxb:bindings>

in the src dir are 2 .xsd that should be compiled. One of them compiled without errors, the other not. Both where extracted from wsdl files.

在 src 目录中有 2 个 .xsd 应该被编译。其中一个编译没有错误，另一个没有。两者都是从 wsdl 文件中提取的。

Your JAXB (JSR-222)implementation is not generating faulty classes. The requiredproperty was added to the @XmlElementRefannotation in JAXB 2.2.

您的JAXB (JSR-222)实现没有生成错误的类。该required属性已添加到@XmlElementRefJAXB 2.2 中的注释中。

• http://docs.oracle.com/javase/7/docs/api/javax/xml/bind/annotation/XmlElementRef.html#required()

• http://docs.oracle.com/javase/7/docs/api/javax/xml/bind/annotation/XmlElementRef.html#required()

Most likely you have generated you JAXB classes in Java SE 7 (which includes JAXB 2.2) and are trying to run then in Java SE 6 (which includes JAXB 2.1). Using a JAXB 2.2 implementation you can create JAXB 2.1 (or JAXB 2.0) compatible code using the -targetflag.

很可能您已经在 J​​ava SE 7（包括 JAXB 2.2）中生成了 JAXB 类，然后尝试在 Java SE 6（包括 JAXB 2.1）中运行。使用 JAXB 2.2 实现，您可以使用该-target标志创建 JAXB 2.1（或 JAXB 2.0）兼容代码。

xjc -target 2.1 schema.xsd

I think its nothing to change in xsd. Try creating one binding file as below, say simple-binding.xjb.

我认为在 xsd 中没有什么可改变的。尝试创建一个如下的绑定文件，比如 simple-binding.xjb。

<jaxb:bindings version="2.1" 
xmlns:jaxb="http://java.sun.com/xml/ns/jaxb" 
xmlns:xjc="http://java.sun.com/xml/ns/jaxb/xjc" 
xmlns:xs="http://www.w3.org/2001/XMLSchema"> 
   <jaxb:globalBindings generateElementProperty="false"/> 
</jaxb:bindings> 

Then use this command when generating java class from xsd. I guess you are wsimportthat comes along with jdk for generating sources.

然后在从 xsd 生成 java 类时使用此命令。我猜你是wsimport用 jdk 来生成源代码的。

wsimport -b simple-binding.xjb

So you will not get the tag XmlElementRef

所以你不会得到标签 XmlElementRef

In my project the same problem occurred because one of the fields of a type defined in a XSD file was duplicated. Therefore JAXB was unable to generate a proper java class because you cannot have two fields with the same name in a java class. As a workaround JAXB gave me the same weird output as in the original post.

在我的项目中，出现了同样的问题，因为 XSD 文件中定义的某个类型的字段被重复。因此 JAXB 无法生成正确的 java 类，因为在 java 类中不能有两个同名的字段。作为一种解决方法，JAXB 给了我与原始帖子中相同的奇怪输出。

I know this thread is quite old, but someone searching for a solution to a similar problem might find this helpful.

我知道这个线程已经很老了，但是寻找类似问题的解决方案的人可能会发现这很有帮助。

If you are using the maven-jaxb2-pluginto run XJC, you may run into this same problem. I fixed it by adding a <specVersion>of 2.1to my pom.xml. As follows:

如果您使用maven-jaxb2-plugin来运行 XJC，您可能会遇到同样的问题。我加入了固定它<specVersion>的2.1到我pom.xml。如下：

<plugin>
  <groupId>org.jvnet.jaxb2.maven2</groupId>
  <artifactId>maven-jaxb2-plugin</artifactId>
  <executions>
    <execution>
      ...
      <configuration>
        ...
        <specVersion>2.1</specVersion>
        ...
      </configuration>
    </execution>
  </executions>
</plugin>
