无法使用 codehaus.mojo jaxb2-maven-plugin 创建 java 类

Question

我有一个基于 Spring 的 Web 应用程序，我试图在其中使用 SOAP 服务。我为此使用 jaxb2-maven-plugin(org.codehaus.mojo)。但是，我看到了一个空的 jaxb2 文件夹，该文件夹在 target 下，我没有看到其中的任何 java 类。我已将 wsdl 正确放置在资源文件夹本身之下。

下面是在 pom.xml 中创建的插件配置

它说在日志中解析和编译模式，但我没有看到在日志中创建了任何 java 类，我看到一个空的 jaxb2 文件夹和另一个空的生成源文件夹被创建。请参考下图：

Answer 1

jaxb2-maven-plugin 将默认创建类到target/generated-sources/jaxb。如果您仍然没有将类放入目标文件夹，那么如果您使用的是 Eclipse，则可以将此文件夹添加到您的项目构建路径中：右键单击项目并选择“构建路径 > 使用源文件夹。

然后你需要运行mvn clean install 它将清理或删除目标文件夹并重新生成所有内容。

Answer 2

试试 codehaus 2.2 版。请记住，您需要稍微更改您的 xml，因为 1.x 和 2.x 之间存在差异。

话虽如此，我想告诉您我遇到了类似的问题。但这可能是由其他原因引起的。我正在使用 IntelliJ，它在 /target/generated-sources/ 下生成空的 jaxb 文件夹。
