上传App时，Apache Tomcat会抛出错误

时间：2014-03-31 17:37:49

标签： java apache maven tomcat

我目前正在尝试在本地Apache Tomcat7上运行我的REST服务。当我访问localhost:8080时，一切正常。如果我使用maven clean install编译我的应用，请将生成的* .war文件复制到cp target/myapp.war /var/lib/tomcat7/webapp并使用systemctl restart tomcat7重新启动Tomcat，我可以通过访问localhost:8080/myapp/rest/myservice按预期使用我的应用。但是，如果现在尝试访问localhost:8080，则会收到HTTP 500错误。查看服务器日志会给我下面的堆栈跟踪。这个错误的原因是什么，我该如何修复它。正如我所说，该应用程序工作正常。

//更新//

我按照建议查看了Resteasy手册并更新了我的web.xml。但是，如果我现在在localhost:8080/spozz/users访问我的服务，我会得到预期的结果。但如果我访问localhost:8080/spozz/，我就再也看不到index.html了。

的web.xml 

<web-app>
    <display-name>The SpoZZ Webservice</display-name>

    <servlet>
        <servlet-name>Resteasy</servlet-name>
        <servlet-class>
            org.jboss.resteasy.plugins.server.servlet.HttpServletDispatcher
        </servlet-class>
        <init-param>
            <param-name>javax.ws.rs.Application</param-name>
            <param-value>net.avedo.spozz.Spozz</param-value>
        </init-param>
    </servlet>

    <servlet-mapping>
        <servlet-name>Resteasy</servlet-name>
        <url-pattern>/*</url-pattern>
    </servlet-mapping>

</web-app>
