java - war 文件没有爆炸的原因可能是什么？

Question

War 文件在部署到 webapps 文件夹后不会爆炸。

我们使用的是 tomcat 7，下面是我遵循的过程。

1. 停止tomcat服务
2. 部署war文件
3. 启动tomcat服务

我已经将 auto deploy 和 unpackwars 设置为“True”

下面是 server.xml 文件:

  <Host name="x.x.x.x"  appBase="/var/lib/dweb13s2/webapps"
        unpackWARs="true" autoDeploy="true">

    <!-- SingleSignOn valve, share authentication between web applications
         Documentation at: /docs/config/valve.html -->
    <!--
    <Valve className="org.apache.catalina.authenticator.SingleSignOn" />
    -->

    <!-- Access log processes all example.
         Documentation at: /docs/config/valve.html
         Note: The pattern used is equivalent to using pattern="common" -->
    <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
           prefix="localhost_access_log." suffix=".txt"
           pattern="%h %l %u %t &quot;%r&quot; %s %b" />

  </Host>

查看文档 RemoveUnpackWARs .可能你还没有去掉之前的目录结构。

If unpackWARs=true and a WAR is updated while Tomcat is stopped, Tomcat will not realise that the unpacked directory structure is from an older version of the WAR and will continue to use it.
