无法用maven项目启动tomcat

Question

使用maven启动tomcat时，出现以下错误

java.util.concurrent.executionException：org.apache.Catalina.LifecyCleException：在java.util.concurrent.futureTask.report（未知源）在java.util.concurrent.futureTask.get（未知源）启动组件[standardengine[Catalina].standardhost[localhost].standardcontext[/web_store]]失败

原因：org.apache.Catalina.LifecyCleException：在org.apache.Catalina.util.LifecyCleBase.start(LifecyCleBase.java:153)启动组件[StandardEngine[Catalina].StandardHost[localhost].StandardContext[/web_store]]失败...更多

由：java.lang.IllegalArgumentException引起：Servlet映射在org.apache.catalina.core.standardContext.AddServletMapping(StandardContext.java:3180)在org.apache.catalina.core.standardContext.AddServletMapping(StandardContext.java:3159)在org.apache.catalina.startup.ContextConfigureContext(ContextConfig.java:1376)指定了一个未知的Servlet名称dispatcherServlet

    <bean

Answer 1

你的错误在这里：

<servlet>
    <servlet-name>dispatcherServlet</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
</servlet>
<servlet-mapping>
    <servlet-name>dispatcherServlet-servlet</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>

在servlet映射中，需要引用在web.xml中定义的servlet，这里只定义了dispatcherservlet，因此在servlet映射中将dispatcherservlet-servlet重命名为dispatcherservlet如下：

<servlet>
    <servlet-name>dispatcherServlet</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
</servlet>
<servlet-mapping>
    <servlet-name>dispatcherServlet</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>
