web-services - java.lang.NoClassDefFoundError : javax/activation/DataSource on wsimport Intellij java 9

Question

我正在尝试使用 JDK-9 使用 Intellij-Idea 2017.2.5 (Webservices -> Generate code from wsdl ...) 为 wsdl 生成类 stub

我遇到了这个异常，我想知道如何告诉 intellij 通过“--add-modules java.activation”来完成操作。

(我想我应该从命令行运行 wsimport ......)

根据您的错误消息，您需要在 pom.xml 中添加以下依赖项

<dependency>
    <groupId>javax.activation</groupId>
    <artifactId>activation</artifactId>
    <version>1.1.1</version>
</dependency>

从 SDK 9 开始，为了让 JAXB 用于 Web 服务，如果您还没有以下依赖项，那么您还需要具有以下依赖项，因为它们不是 SDK 的一部分。

<dependency>
    <groupId>javax.xml.bind</groupId>
    <artifactId>jaxb-api</artifactId>
    <version>2.3.0</version>
</dependency>

<dependency>
    <groupId>com.sun.xml.bind</groupId>
    <artifactId>jaxb-core</artifactId>
    <version>2.3.0</version>
</dependency>

<dependency>
   <groupId>com.sun.xml.bind</groupId>
   <artifactId>jaxb-impl</artifactId>
   <version>2.3.0</version>
</dependency>
