Tomcat连接Mysql测试样例

首先在mysql中建立如图数据库：

1、
修改contex.xml文件：

                type="javax.sql.DataSource"
                maxActive="50" maxIdle="10" maxWait="5000"
                username="root" password="bobo365"
                driverClassName="org.gjt.mm.mysql.Driver"
                url="jdbc:mysql://localhost/test1" />

2、
修改web.xml文件：

            DB Connection
            jdbc/mysql
            javax.sql.DataSource
            Container
          

 

3、

测试文档test.jsp：
<%@ page language="java" pageEncoding="UTF-8"%>
<%@ page import="java.sql.*"%>  
<%@ page import="javax.sql.*"%>  
<%@ page import="javax.naming.*"%>


  
    
        
        
           
        
        
          
  
  
        <% 
    out.print("My data test:
");  
    DataSource ds = null;  
      try{
            InitialContext ctx=new InitialContext();
            ds=(DataSource)ctx.lookup("java:comp/env/jdbc/mysql");
            Connection conn = ds.getConnection(); 
            Statement stmt = conn.createStatement();
            String strSql = " select * from pet";
            ResultSet rs = stmt.executeQuery(strSql);
                   while(rs.next()){

                                        out.print("name:" + rs.getString(1));

                                        out.print("\towner:" + rs.getString(2));

                                        out.print("\tbirth:" + rs.getString("birth"));
                                        out.println("
");
                }
                rs.close();
                stmt.close();
                conn.close();
     }catch(Exception ex){
             ex.printStackTrace();
     }
        %> 
  

 

4、显示样式：
