java - 如何使用maven jaxb实现serialized生成类

Question

我希望所有 xjc 生成的类都实现可序列化接口(interface)。阅读 post 的解决方案后我实现了它，但是 jaxb2-maven-plugin 抛出以下错误:

[ERROR] file: mapping.xsd [17,34] org.xml.sax.SAXParseException; systemId: file:mapping.xsd; lineNumber: 17; columnNumber: 34; src-annotation: elements can only contain and elements, but 'globalBindings' was found. at com.sun.org.apache.xerces.internal.util.ErrorHandlerWrapper.createSAXParseException(ErrorHandlerWrapper.java:203) at com.sun.org.apache.xerces.internal.util.ErrorHandlerWrapper.error(ErrorHandlerWrapper.java:134) at

我的 xsd 示例:

<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
           xmlns:jaxb="http://java.sun.com/xml/ns/jaxb"
           xmlns:xjc="http://java.sun.com/xml/ns/jaxb/xjc"
           jaxb:extensionBindingPrefixes="xjc"
           attributeFormDefault="unqualified"
           elementFormDefault="qualified">
    <xs:element name="MappingFile" type="MappingFileType">
        <xs:annotation>
            <jaxb:globalBindings>
                <xjc:serializable uid="43538530765l"/>
            </jaxb:globalBindings>
        </xs:annotation>

Maven 插件:

<plugin>
                <groupId>org.codehaus.mojo</groupId>
                <artifactId>jaxb2-maven-plugin</artifactId>
                <version>2.3</version>
                <configuration>
                    <sources>
                        <source>xxxx/yyy/mapping.xsd</source>
                    </sources>
                    <packageName>xx.yy.zz.jaxp</packageName>

                </configuration>
            </plugin>

我需要使用任何依赖项来避免此异常吗？请提出建议。

您的绑定(bind)文件应如下所示:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<jaxb:bindings
        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"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:schemaLocation="http://java.sun.com/xml/ns/jaxb http://java.sun.com/xml/ns/jaxb/bindingschema_2_0.xsd"
        version="2.1">

    <jaxb:globalBindings>
        <xjc:serializable uid="1" />
    </jaxb:globalBindings>
</jaxb:bindings>

此外，触摸特定目录中的绑定(bind)文件并在 Maven 插件特定配置中引用它。示例:

<configuration>
    <sources>
      <source>src/main/xjb/xsd</source>
    </sources>
  <packageName>xx.yy.zz.jaxp</packageName>
    <xjbSources>
        <xjbSource>src/main/xjb/jaxb-bindings.xjb</xjbSource>
    </xjbSources>
</configuration>
