如何使用jaxb2-maven-plugin 2.x从WSDL生成Java类?

Question

我正在尝试使用插件jaxb2-maven-plugin从wsdl创建Java类。

在 1.5 版本中，来自 WSDL 的 Generate classes with jaxb2-maven-plugin 的代码有效：

<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>jaxb2-maven-plugin</artifactId>
<version>1.5</version>
<executions>
<execution>
<id>xjc</id>
<goals><goal>xjc</goal></goals>
</execution>
</executions>
<configuration>
<!-- Package to store the generated file -->
<packageName>com.example.demo.wsdl</packageName>
<!-- Treat the input as WSDL -->
<wsdl>true</wsdl>
<!-- Input is not XML schema -->
<xmlschema>false</xmlschema>
<!-- The WSDL file that you saved earlier -->
<schemaFiles>horarios.wsdl</schemaFiles>
<!-- The location of the WSDL file -->
<schemaDirectory>${project.basedir}/src/main/resources</schemaDirectory>
<!-- The output directory to store the generated Java files -->
<outputDirectory>${project.basedir}/src/main/java</outputDirectory>
<!-- Don't clear output directory on each run -->
<clearOutputDir>false</clearOutputDir>
</configuration>
</plugin>

但是当使用插件版本 2.3.1 时，我收到此错误：

Failed to execute goal org.codehaus.mojo:jaxb2-maven-plugin:2.3.1:xjc (xjc) on project demo: MojoExecutionException: NoSchemasException -> [Help 1]

有人知道如何将WSDL文件与这个新的插件版本一起使用吗？

Answer 1

我已经找到了解决方案。

当 jaxb2-maven-plugin 版本为>= 2.0 时，您必须使用以下配置：

<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>jaxb2-maven-plugin</artifactId>
<version>2.3.1</version>
<executions>
<execution>
<id>xjc</id>
<goals>
<goal>xjc</goal>
</goals>
</execution>
</executions>
<configuration>
<packageName>com.example.demo.wsdl</packageName>
<sourceType>wsdl</sourceType>
<sources>
<source>src/main/resources/horarios.wsdl</source>
</sources>
<outputDirectory>target/generated-sources/</outputDirectory>
<clearOutputDir>false</clearOutputDir>
</configuration>
</plugin>

区别不仅在于语法。该版本不会在项目(src/main/java(中创建类，而是在您用outputDirectory编写的目录和packageName包中创建。

当您使用生成的类时，它是透明的，就像它在同一项目中一样。

如果要从 XSD 开始：

<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>jaxb2-maven-plugin</artifactId>
<version>2.3.1</version>
<executions>
<execution>
<id>xjc</id>
<goals>
<goal>xjc</goal>
</goals>
</execution>
</executions>
<configuration>
<xjbSources>
<xjbSource>src/main/resources/global.xjb</xjbSource>
</xjbSources>
<sources>
<source>src/main/resources/Ventas.xsd</source>
</sources>
<outputDirectory>${basedir}/src/main/java</outputDirectory>
<clearOutputDir>false</clearOutputDir>
</configuration>
</plugin>
