1.在tomcat图形界面里创建jndi数据源.(Tomcat Administration菜单里)
2.在对应的web应用工程下绑定该连接源.例如假设该Web应用项目名为SpringMVC.则在Tomcat5.X系列下的对应配置文件名(包含指定的路径:C:\Tomcat 5.0\conf\Catalina\localhost\SpringMVC.xml)
3.SpringMVC.xml内容为:
  <?xml version='1.0' encoding='utf-8'?>
<Context docBase="E:/workspace/SpringMVC" path="/SpringMVC" reloadable="true" workDir="E:\workspace\SpringMVC\work">
  <!--Resource auth="Container" name="jdbc/spring" type="javax.sql.DataSource"/-->
 <!--应用工程,指定绑定的jndi-->
  <ResourceLink name="jdbc/spring" global="jdbc/spring" type="javax.sql.DataSource" />
</Context>
4.Tomcat5.x下的配置数据源在,server.xml文件中.
5.Spring利用该连接源,进行数据库操作.(如何配置)
   1.在该Web应用工程下的web.xml中配置Spring控制台
   2.web.xml文件的内容
      <?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE web-app PUBLIC '-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN' 'http://java.sun.com/dtd/web-app_2_3.dtd'>
   <web-app>    
    <servlet>
    <servlet-name>HelloWorld</servlet-name>
    <servlet-class>HelloWorld</servlet-class>
    </servlet>
    <servlet>
    <servlet-name>springapp</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>/WEB-INF/springappservlet.xml</param-value>
    </init-param>        
    </servlet>    
    <servlet-mapping>
      <servlet-name>HelloWorld</servlet-name>
      <!-- 字母区分大小写-->
      <url-pattern>/servlet/HelloWorld</url-pattern>
       </servlet-mapping>
      <servlet-mapping>
      <servlet-name>springapp</servlet-name>
      <url-pattern>*.do</url-pattern>
   </servlet-mapping>
   <!--(过滤器) 对提交的数据进行统一的编码-->
   <filter>
   <filter-name>encoding</filter-name>
   <filter-class>EncodingFilter</filter-class>
   <init-param>
   <param-name>encoding</param-name>
   <param-value>gb2312</param-value>
   </init-param>
   </filter> 
   <filter-mapping>
   <filter-name>encoding</filter-name>
   <url-pattern>/*</url-pattern> 
   </filter-mapping>    
</web-app>

  3.创建对应的spring配置即Web.xml中指定的目录下的配置文件>/WEB-INF/springappservlet.xml
     <?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">

<!-- SelectMethod=cursor :打开游标-->
<!-- 用SQL Server驱动一次select很多数据最好在
connection string中加上SelectMethod=Cursor,
以利用服务器端游标加快速度,其实不只sqlserver,
oracle的jdbc,只要使用PreparedStatement,
驱动默认就使用游标,sqlserver则不然,
必须使用SelectMethod=Cursor才打开游标-->

  4.对应的应用UserAction
  import java.io.UnsupportedEncodingException;

import org.springframework.jdbc.core.JdbcTemplate;
import org.springframework.validation.BindException;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.SimpleFormController;

public class UserAction extends SimpleFormController {

 private String fail_view;

 private String success_view;

 private JdbcTemplate jdbcTemplate;

 protected ModelAndView onSubmit(Object cmd, BindException ex)
   throws Exception {
  System.out.println("--------go into UserAction-------");
  UserInfo userInfo = (UserInfo) cmd;
  System.out.println("name=" + userInfo.getName() + ",sex="
    + userInfo.getSex() + ",age=" + userInfo.getAge());
  if (login(userInfo) == 1) {   
   insertUser(userInfo);
   return new ModelAndView(this.success_view);
  }
  return new ModelAndView(this.fail_view);
 }

 public void insertUser(UserInfo user) throws UnsupportedEncodingException {
  System.out.println("-----------------");
  System.out.println("name=" + user.getName() + ",sex=" + user.getSex()
    + ",age=" + user.getAge());
  System.out.println("-----------------");
  //if(user.getName()!=null && !user.getName().equals(""))
  //user.setName(new String(user.getName().getBytes("ISO8859_1"),"GBK"));
  System.out.println("name=" + user.getName() + ",sex=" + user.getSex()
    + ",age=" + user.getAge());
  jdbcTemplate.update("INSERT INTO USERS VALUES('" + user.getSex()
    + "', '" + user.getName() + "', '" + user.getAge() + "')");
 }

 private int login(UserInfo userInfo) {
  if (userInfo.getName().equals("李冲")) {
   System.out.println("11");
   return 0;
  } else
   return 1;
 }

 public String getFail_view() {
  return fail_view;
 }

 public void setFail_view(String fail_view) {
  this.fail_view = fail_view;
 }

 public String getSuccess_view() {
  return success_view;
 }

 public void setSuccess_view(String success_view) {
  this.success_view = success_view;
 }

 public void setJdbcTemplate(JdbcTemplate jdbcTemplate) {
  this.jdbcTemplate = jdbcTemplate;
 }
}
