tomcat+tomcat例子游戲+maven自動下載jar+uuid用法

1 tomcat
http://localhost:8080/manager/html
只可用role為 manager-gui
<tomcat-users>
<role rolename="manager-gui"/>
<user username="tomcat" password="tomcat" roles="manager-gui"/>
</tomcat-users>


裡面有非常多的小例子，還有貪吃蛇遊戲

2
for (int i = 0; i < 10; i++) {
System.out.println(UUID.randomUUID());
}


uuid值

3 maven的tomcat外掛  有問題


mvn tomcat:deploy 或


mvn tomcat:redeploy


3 mvn eclipse:eclipse  用來使用配置檔案來下載包的
