TOME+8.0-OperationNotSupportedException:上下文为只读]

tomee-8 tomcat9 java

Ted Spradley · 技术社区 · 6 年前

在本地Eclipse IDE和远程CentOS服务器中使用tome+8.0(tomcat 9.0.12)。应用程序在本地正常启动,以前在远程服务器上正常启动。现在,在添加一个javascriptWebSocket之后,在部署到远程服务器时抛出一个NPE。

有什么建议可以从哪里开始寻找?这是一个令人头疼的问题。

谢谢您, 泰德S

此应用程序使用此处引用的tomcat's server.xml应用程序元素中的条目从Web应用程序根目录之外的目录提供图像文件。 Serve static files from Tomcat

<Host name="www.example.com" appBase="webapps"
                 unpackWARs="true" autoDeploy="true" >
    <Alias>example.com</Alias>
    <Valve className="org.apache.catalina.valves.AccessLogValve" 
        directory="logs"
        prefix="oneme_access_log." suffix=".txt"
        pattern="%h %l %u %t &quot;%r&quot; %s %b" />

    <Context docBase="/var/www/html/example/media" 
            path="/myapp/media" 
            reloadable="true" />
</Host>

问题是通过(按此顺序)解决的

删除应用程序war文件
清除Sprint期间输入的不必要的Maven依赖项
评论元素
停止并重新启动Tomcat
取消对元素的注释
停止并重新启动Tomcat

在上述每个步骤之后尝试部署。我不知道为什么会这样。应用程序之前已经正确部署,然后在冲刺之后,它会给出上面的错误。我怀疑马文所加的相互冲突的罐子不知何故扰乱了汤姆猫的状态。

希望分享这对某人有帮助。
