tomcat端口

*

一，同一个tomcat中，部署多个程序，使用同一个端口

1，http://217.65.63.124:6789/ddd

ddd项目部署在tomcat中，该tomcat可同时部署多个java项目，开始我以为同一个端口不可以，

其实可以，因为http://217.65.63.124:6789是访问该ip下的tomcat程序，如果启动了另一个tomcat程序，则不可以用同一个端口

类似，配置多个service节点即可

二、Tomcat 部置方式

TOMCAT部署项目有3种方法：
1、直接把项目放在webapps里
2、修改conf里server.xml文件，添加一个Context，指向项目的目录
3、在Catalina/localhost目录里，新增一个xml文件，添加一个Context内容，指向项目的目录。
<Context path="/目录名" docBase="e:/example" debug="0" reloadable="true" />

优先级别为：3>2>1

第3个方法有个优点，可以定义别名。服务器端运行的项目名称为path，外部访问的URL则使用XML的文件名。这个方法很方便的隐藏了项目的名称，对一些项目名称被固定不能更换，但外部访问时又想换个路径，非常有效。

第2、3还有优点，可以定义一些个性配置，如数据源的配置等。

catalina下localhost下会生成一个xml

如wpt项目

wpt.xml

<!-- oracle setting -->
<Context>
<Resource name="jdbc/oracle" type="javax.sql.DataSource" username="aaa"
    password="aaa"
    driverClassName="oracle.jdbc.driver.OracleDriver"
    maxIdle="2" maxWait="5000"
    url="jdbc:oracle:thin:@218.204.137.82:1521:info"
    maxActive="4" />
</Context>    

<!-- mysql setting
<Context>
<Resource name="jdbc/mysql" type="javax.sql.DataSource" username="root"
    password="1234567"
    driverClassName="com.mysql.jdbc.Driver"
    maxIdle="2" maxWait="5000"
    url="jdbc:mysql://localhost:3306/sshe?useUnicode=true&amp;characterEncoding=utf-8"
    maxActive="4" />
</Context>     -->
