邵波的空间 的 Dwr-EditTable完整版
Dwr是Java领域一个著名的服务器端Ajax框架,借助 Dwr的帮助,我们可以直接在客户端页面通过Javascript调用远程Java的方法。
  看 Dwr的示例中有一个EditTable的示例,觉得在实际使用中会非常的有用,就把此示例进行了扩展,实现与数据库的交互,在页面上可以直接添加用户、修改用户和删除用户操作。
  数据库设计:
  
Java代码 复制代码
  1. create table jackdemo1   
  2. (   
  3.   id int primary key auto_increment,   
  4.   name varchar(50),   
  5.   age int,   
  6.   address varchar(200)   
  7. );   
  8.       
create table jackdemo1
(
  id int primary key auto_increment,
  name varchar(50),
  age int,
  address varchar(200)
);
    

  使用 Dwr,首先要配置Web.xml文件:
Java代码 复制代码
  1. <?xml version="1.0" encoding="UTF-8"?>   
  2. <web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"  
  3.     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  
  4.     xsi:schemaLocation="http://java.sun.com/xml/ns/javaee    
  5.     http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">   
  6.     <servlet>   
  7.         <servlet-name>dwr-invoker</servlet-name>   
  8.         <servlet-class>   
  9.             org.directwebremoting.servlet.DwrServlet   
  10.         </servlet-class>   
  11.     </servlet>   
  12.     <servlet-mapping>   
  13.         <servlet-name>dwr-invoker</servlet-name>   
  14.         <url-pattern>/dwr/*</url-pattern>   
  15.     </servlet-mapping>   
  16. </web-app>  
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
 http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
 <servlet>
  <servlet-name>dwr-invoker</servlet-name>
  <servlet-class>
   org.directwebremoting.servlet.DwrServlet
  </servlet-class>
 </servlet>
 <servlet-mapping>
  <servlet-name>dwr-invoker</servlet-name>
  <url-pattern>/dwr/*</url-pattern>
 </servlet-mapping>
</web-app>

然后要在web.xml文件同一级目录下建立一个 dwr.xml文件,具体的配置如下:
Java代码 复制代码
  1. <!DOCTYPE dwr PUBLIC   
  2.     "-//GetAhead Limited//DTD Direct Web Remoting 2.0//EN"  
  3.     "http://getahead.org/dwr/dwr20.dtd">   
  4. <dwr>   
  5.     <allow>   
  6.         <create javascript="People" creator="new">   
  7.             <param name="class" value="com.jack.dwr.simple.People"></param>   
  8.         </create>   
  9.         <convert match="com.jack.dwr.simple.Person" converter="bean" javascript="Person"></convert>   
  10.     </allow>   
  11. </dwr>  
<!DOCTYPE dwr PUBLIC
    "-//GetAhead Limited//DTD Direct Web Remoting 2.0//EN"
    "http://getahead.org/dwr/dwr20.dtd">
<dwr>
 <allow>
  <create javascript="People" creator="new">
   <param name="class" value="com.jack.dwr.simple.People"></param>
  </create>
  <convert match="com.jack.dwr.simple.Person" converter="bean" javascript="Person"></convert>
 </allow>
</dwr>

其实Javascript="People"是要在客户端使用的对象名称,<param>是对象的Java类名,因为People类中对应的方法中使用了Person类,所在在这里要使用<convert>进行转换。
Person类是一个POJO类:
Java代码 复制代码
  1. package com.jack.dwr.simple;   
  2.   
  3.   
  4. public class Person {   
  5.     private int id;   
  6.     private String name;   
  7.     private int age;   
  8.     private String address;   
  9.   
  10.     public int getId() {   
  11.         return id;   
  12.     }   
  13.   
  14.     public void setId(int id) {   
  15.         this.id = id;   
  16.     }   
  17.   
  18.     public String getName() {   
  19.         return name;   
  20.     }   
  21.   
  22.     public void setName(String name) {   
  23.         this.name = name;   
  24.     }   
  25.   
  26.     public int getAge() {   
  27.         return age;   
  28.     }   
  29.   
  30.     public void setAge(int age) {   
  31.         this.age = age;   
  32.     }   
  33.   
  34.     public String getAddress() {   
  35.         return address;   
  36.     }   
  37.   
  38.     public void setAddress(String address) {   
  39.         this.address = address;   
  40.     }   
  41.   
  42. }  
package com.jack.dwr.simple;


public class Person {
 private int id;
 private String name;
 private int age;
 private String address;

 public int getId() {
  return id;
 }

 public void setId(int id) {
  this.id = id;
 }

 public String getName() {
  return name;
 }

 public void setName(String name) {
  this.name = name;
 }

 public int getAge() {
  return age;
 }

 public void setAge(int age) {
  this.age = age;
 }

 public String getAddress() {
  return address;
 }

 public void setAddress(String address) {
  this.address = address;
 }

}

上面的各个属性对应数据库中的字段信息。
People类是对数据进行操作类也是就是具体的业务类:

以上就是具体的业务操作信息,其中
DBConnection.getConnectionMySqlDB("3306", "jackdemo","root", "jack")方法用于建立与数据库的连接。
DBConnection是一个数据库连接类:
Java代码 复制代码
  1. package com.jack.dwr.simple;   
  2.   
  3. import java.sql.Connection;   
  4. import java.sql.DriverManager;   
  5.   
  6. public class DBConnection {   
  7.     public static Connection getConnectionMySqlDB(String post, String dbName,String userName,String password)   
  8.             throws Exception {   
  9.         String driver = "com.mysql.jdbc.Driver";   
  10.         String url = "jdbc:mysql://localhost:" + post + "/" + dbName;   
  11.         String user = userName;   
  12.         String pwd = password;   
  13.         Class.forName(driver);   
  14.         return DriverManager.getConnection(url, user, pwd);   
  15.     }   
  16. }  
package com.jack.dwr.simple;

import java.sql.Connection;
import java.sql.DriverManager;

public class DBConnection {
 public static Connection getConnectionMySqlDB(String post, String dbName,String userName,String password)
   throws Exception {
  String driver = "com.mysql.jdbc.Driver";
  String url = "jdbc:mysql://localhost:" + post + "/" + dbName;
  String user = userName;
  String pwd = password;
  Class.forName(driver);
  return DriverManager.getConnection(url, user, pwd);
 }
}

当然你也可以自己扩展别的数据库连接方法。
具体的JSP页面:
