用Maven，Tomcat 7和Websocket构建一个可执行的War/Jar

我想用Maven和Tomcat 7构建一个可执行的WAR/JAR。 该项目包含Websocket和REST API。用Maven，Tomcat 7和Websocket构建一个可执行的War/Jar

为了做到这一点，我添加了以下插件pom.xml文件：

<groupId>org.apache.tomcat.maven</groupId> 
      <artifactId>tomcat7-maven-plugin</artifactId> 
      <version>2.1</version> 
      <executions> 
       <execution> 
        <id>tomcat-run</id> 
        <goals> 
         <goal>exec-war-only</goal> 
        </goals> 
        <phase>package</phase> 
        <configuration> 
         <path>/TransSafeGWService</path> 
         <enableNaming>false</enableNaming> 
         <finalName>standalone.jar</finalName> 
         <charset>utf-8</charset> 
        </configuration> 
       </execution> 
      </executions>

后，由于REST服务是工作，但WebSocket的服务是不是，我添加其他依赖于插件：

 <plugin> 
      <groupId>org.apache.tomcat.maven</groupId> 
      <artifactId>tomcat7-maven-plugin</artifactId> 
      <version>2.1</version> 
      <executions> 
       <execution> 
        <id>tomcat-run</id> 
        <goals> 
         <goal>exec-war-only</goal> 
        </goals> 
        <phase>package</phase> 
        <configuration> 
         <path>/TransSafeGWService</path> 
         <enableNaming>false</enableNaming> 
         <finalName>standalone.jar</finalName> 
         <charset>utf-8</charset> 
        </configuration> 
       </execution> 
      </executions> 
      <dependencies> 

       <dependency> 
        <groupId>org.apache.tomcat</groupId> 
        <artifactId>tomcat7-websocket</artifactId> 
        <version>7.0.67</version> 
       </dependency> 

       <dependency> 
        <groupId>org.apache.tomcat</groupId> 
        <artifactId>tomcat-util</artifactId> 
        <version>7.0.67</version> 
       </dependency> 

       <dependency> 
        <groupId>org.apache.tomcat</groupId> 
        <artifactId>tomcat-coyote</artifactId> 
        <version>7.0.67</version> 
       </dependency> 

      </dependencies> 
     </plugin>

使用的依赖，我得到这样的错误：

在这种情况可能是什么问题？

我觉得你的问题很可能是用错servlet api的版本。 Tomcat 7支持3.0及更低版本，但似乎您使用的是servlet版本3.1。

你的例外显示this method not found，这只是servlet 3.1或更高版本的一部分。

Since: 
Servlet 3.1

即使你没有列入讨论的web.xml文件，堆栈跟踪导致该决议

请参阅您的web.xml有这个声明。

<web-app version="3.0" 
    xmlns="http://java.sun.com/xml/ns/javaee" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xsi:schemaLocation=" 
    http://java.sun.com/xml/ns/javaee 
    http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">

更新：

您正在使用2.1版本tomcat7-maven-plugin它使用Tomcat版本7.0.37。然后在依赖关系中，您尝试使用不同版本7.0.67的tomcat jar。两者必须使用相同的版本。

你有两种可能性：

  1. 任何一个所有罐子的版本7.0.37

  2. 您可以使用最新版本的2.2 of tomcat7-maven-plugin和使用属性setting the tomcat version。我会 喜欢这一个。也许你可以用2.1来设置这个属性。你可以尝试 。

我在前一篇文章中添加了web.xml描述。它已经有了你写的声明。 – ant
