java.lang.NoClassDefFoundError:wsimport上的javax/activation/DataSource Intellij java 9

Question

我正在尝试使用JDK-9为Intellij-Idea 2017.2.5(Webservices - >从wsdl生成代码...)生成wsdl的类存根

我得到这个异常,我想知道如何告诉intellij传递"--add-modules java.activation"来完成操作.

(我想我应该从命令行运行wsimport ...)

Answer 1

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,对于JAXB,要为Web服务工作,如果您还没有它们,则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>

Answer 2

我想它可能很有用。从 Java 8 切换到 10 时，我的soap 项目中有这些额外的包。Gradle：

compile "javax.xml.bind:jaxb-api:2.3.0"
compile "javax.activation:activation:1.1"
compile "com.sun.xml.bind:jaxb-impl:2.3.0"
compile "com.sun.xml.bind:jaxb-core:2.3.0"
compile "com.sun.xml.ws:rt:2.3.0"
compile "com.sun.xml.ws:jaxws-rt:2.3.0"

只是为了其他有同样例外的人来到这里：

如果您使用诸如 tomcat 之类的 Web 服务器，并且如果您还需要在那里提供激活 jar，也会出现此问题。一种可能的解决方案是将其放在 tomcat 的 lib 文件夹中（或使用 common.loader 功能）。
