无法通过Tomcat7 Maven插件启动RESTEasy Maven项目（ExecutionException）

标签： java maven tomcat tomcat7 resteasy

我正在开发一个使用 RESTEasy 3.0.6.Final 作为其REST提供程序框架的Maven Java项目。由于此应用程序将通过其Tomcat 7容器部署到AWS Elastic Beanstalk，因此我已将项目设置为使用 Tomcat Maven Plugin 作为其本地Web容器。我的pom.xml文件中有以下相关的依赖项和插件：

<dependency>
    <groupId>org.jboss.resteasy</groupId>
    <artifactId>resteasy-jaxrs</artifactId>
    <version>${resteasy.version}</version>
</dependency>
<dependency>
    <groupId>org.jboss.resteasy</groupId>
    <artifactId>resteasy-guice</artifactId>
    <version>${resteasy.version}</version>
</dependency>
<dependency>
    <groupId>org.jboss.resteasy</groupId>
    <artifactId>resteasy-jackson2-provider</artifactId>
    <version>${resteasy.version}</version>
</dependency>
<dependency>
    <groupId>org.jboss.resteasy</groupId>
    <artifactId>resteasy-servlet-initializer</artifactId>
    <version>${resteasy.version}</version>
</dependency>
<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>javax.servlet-api</artifactId>
    <version>3.1.0</version>
</dependency>
...
<plugin>
    <groupId>org.apache.tomcat.maven</groupId>
    <artifactId>tomcat7-maven-plugin</artifactId>
    <version>2.2</version>
    <configuration>
        <path>/</path>
    </configuration>
</plugin>

然后，当我使用mvn clean install tomcat7:run构建并运行项目时，我在控制台中出现以下错误，导致构建失败：

有没有人知道可能是什么问题？请注意，我已尝试使用空的web.xml文件（除了将<listener-class>设置为GuiceResteasyBootstrapServletContextListener的子级，以便在 RESTEasy <中自定义 Guice / strong>）和一个web.xml文件，该文件对Servlet版本3.0（link）的独立servlet容器使用servlet配置。提前谢谢。

注意：如果我使用Maven Jerry插件启动我的应用程序，通过mvn clean install org.mortbay.jetty:jetty-maven-plugin::run，那么我的项目确实会成功构建。

解决！

一个问题是我应该使用mvn clean tomcat7:run-war代替mvn clean tomcat7:run。同样，与RESTEasy文档中的内容相反，我需要在web.xml中为<servlet>添加org.jboss.resteasy.plugins.server.servlet.HttpServletDispatcher标记，尽管我使用的是Servlet 3.0+容器。

使用

<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>javax.servlet-api</artifactId>
    <version>3.1.0</version>
    <scope>provided</scope>
</dependency>
