我尝试运行WAR到我的Tomcat 9.0.5部署正常，但是当我尝试启动应用程序时，我遇到了这个例外：

有什么问题？我该怎么办？谢谢！

Answer 1

Weblogic是一个完整的Java EE服务器，而Tomcat只是一个servlet容器。您使用的是Jersey，它是JAX-RS的一种实现，默认情况下在Tomcat中不可用。这意味着当您尝试在Tomcat中加载JAX-RS类时，它将无法找到它们。要解决此问题，您还需要添加JAX-RS api作为依赖项（非提供）。

使用以下命令将其添加到您的pom中：

<dependency>
  <groupId>javax.ws.rs</a></groupId>
  <artifactId>javax.ws.rs</a>-api</artifactId>
  <version>2.0.1</version>
</dependency>

此外，Jersey工件的位置已被移动，以使用最新版本：

<dependency>
  <groupId>org.glassfish.jersey.containers</groupId>
  <artifactId>jersey-container-servlet</artifactId>
  <version>2.22.1</version>
</dependency>
<!-- Required only when you are using JAX-RS Client -->
<dependency>
  <groupId>org.glassfish.jersey.core</groupId>
  <artifactId>jersey-client</artifactId>
  <version>2.22.1</version>
</dependency>

Answer 2

您应该只有javaee-api作为提供的依赖，删除这些行：

<dependency>
    <groupId>javax</groupId>
    <artifactId>javaee-api</artifactId>
    <version>6.0</version>
</dependency>

Answer 3

我建议您从http://java.sun.com/javaee/获取完整版的javaee.jar文件。 javaee.jar一般位于“\ JAVA_HOME \ lib”文件夹中。将此jar包含在Maven资源库/类路径中。这应该可以解决您的问题。完成此操作后，从pom.xml中删除依赖项。

Answer 4

尝试更改

    <dependency>
        <groupId>javax</groupId>
        <artifactId>javaee-api</artifactId>
        <version>6.0</version>
        <scope>provided</scope>
    </dependency>

到

<!-- https://mvnrepository.com/artifact/org.jboss.spec/jboss-javaee-7.0 -->
<dependency>
    <groupId>org.jboss.spec</groupId>
    <artifactId>jboss-javaee-7.0</artifactId>
    <version>1.0.3.Final</version>
    <type>pom</type>
    <scope>provided</scope>
</dependency>

Answer 5

java.net中的javaee不包含任何方法体，但仅包含API名称。因此，它只能用于编译，而不能用于与应用程序一起运行或部署

您的应用程序能够在Weblogic中运行的原因是，Weblogic与Java EE兼容。如果需要在tomcat中运行，请从http://java.sun.com/javaee/获取原始完整版本的javaee.jar文件。

只需下载并安装J2EE SDK，就可以在“\ J2EE_SDK_FOLDER \ lib”文件夹中找到javaee.jar。将它包含到您的本地Maven存储库或poject类路径将消除上述错误消息
