一个tomcat同时部署有启动顺序的多个项目

前言

一个tomcat部署多个项目常用的方法是将所有的项目放置在webapps里面，共用同一个端口，各项目根据项目名进行区分。如果多个项目有启动先后顺序，这样的做法就显得不合适，因为tomcat启动是根据项目名称字母顺序来启动。网上有种做法，在conf\Catalina\localhost文件夹下建立需要首先启动的项目相应文件，如果是两个项目没有问题，但多个项目仍然不方便控制。实用的做法是定义多个service标签，各项目使用不同的端口号。

操作方法

1、conf\server.xml定义多个service，需要注意各service端口、redirectPort端口和appBase对应文件夹都要不一样

2、在tomcat文件根目录创建相应文件夹

3、将项目放置在相应文件夹下面
