这是由于电脑中的数据库端口号8080被占用，我的电脑装了oracle启动tomcat是就出现了个错误。
　　解决方案：
　　 oracle端口号修改问题
 如果用户要修改oracle的端口号需要超级管理员进行登录
 登录的口令：sys
 登录的密码：root 是设置的密码
 连接的方式：sysDBA模式
　　 第一步：获取端口号：
SQL> select dbms_xdb.getHTTPPort from dual;
GETHTTPPORT
-----------
       8080
 第二步：设置端口号：
SQL> exec dbms_xdb.setHTTPPort(8088);
PL/SQL procedure successfully completed
-----------
 第三步：重新获取
SQL> select dbms_xdb.getHTTPPort from dual;
GETHTTPPORT
-----------
       8088   //在这里发现oracle的端口号已经被修改了
