tomcat

将war包丢到webapps目录中，执行bin目录中的startup.sh后，访问应用的接口，报404。

解决办法：

编辑tomcat的conf目录中的context.xml文件，在Context的标签上添加属性，如下

<Context path="demo" docBase="../webapps/demo" privileged="true">

其中path是之后访问接口的根目录，实测只能配置为项目名，即demo或者/demo，其他的(包括只配斜杠)都不行，访问接口时会报找不到网页错误。

docBase是项目的路径，相对路径或者全路径(/home/koushengrui/app/apache-tomcat-8.5.23/webapps/demo)都行，需要具体到项目目录，推荐相对路径。

另外，更改context.xml的话，不用重启tomcat，tomcat会自动重新部署该应用。
