Wildfly 找不到 JAX-WS

Question

我正在將帶有 Java7/JBoss7 的舊系統遷移到 Java8/Wildfly14，它編譯正常，但是當我嘗試部署時出現以下錯誤：

ERROR [org.jboss.msc.service.fail] (MSC service thread 1-1) MSC000001: Failed to start service jboss.deployment.unit."rt-app-war-9.2-SNAPSHOT.war".POST_MODULE: org.jboss.msc.service.StartException in service jboss.deployment.unit."rt-app-war-9.2-SNAPSHOT.war".POST_MODULE: WFLYSRV0153: Failed to process phase POST_MODULE of deployment "rt-app-war-9.2-SNAPSHOT.war"

包含的 jar 是 javaee-api-7.0.jar，它在我的 pom 中：

<dependency>
    <groupId>javax</groupId>
    <artifactId>javaee-api</artifactId>
    <version>7.0</version>
    <scope>provided</scope>
</dependency>

當我在 Eclipse 中按 ctrl+shift+T 並輸入“javax.xml.ws.WebServiceException”時，它會在那個 jar 中找到它，所以我不明白為什么 Wildfly 說它找不到這個類。

我錯過了什么嗎？

Answer 1

我相信這是因為您沒有對 JAX-WS API 的依賴。 您能否嘗試添加以下依賴項：

<dependency>
  <groupId>javax.xml.ws</groupId>
  <artifactId>jaxws-api</artifactId>
  <version>2.3.1</version>
</dependency>

Answer 2

這就是解決方案。 我這樣做了，然后成功部署了war文件

jboss-deployment-structure.xml

<jboss-deployment-structure>
    <deployment>
        <exclude-subsystems>
            <subsystem name="webservices"/>
            <subsystem name="logging"/>
            <subsystem name="resteasy"/>
            <subsystem name="jaxrs" />
        </exclude-subsystems>
        <dependencies>
            <module name="javax.jws.api" export="true"/>
        </dependencies>
    </deployment>
</jboss-deployment-structure>
