Hibernate+struts+mysql+dwr(/*接受返回对象List)绑定下拉框
[quote]首先hibernate.cfg.xml[/quote]
<?xml version='1.0' encoding='UTF-8'?><!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd"><!-- Generated by MyEclipse Hibernate Tools. --><hibernate-configuration> <session-factory> <property name="connection.username">root</property> <property name="connection.url"> jdbc:mysql://localhost:3306/test </property> <property name="dialect"> org.hibernate.dialect.MySQLDialect </property> <property name="myeclipse.connection.profile">dd</property> <property name="connection.driver_class"> com.mysql.jdbc.Driver </property> <property name="show_sql">true</property> <mapping resource="com/accp/entity/Student.hbm.xml" /> </session-factory></hibernate-configuration>

接下来是web.xml
[/quote]
<?xml version="1.0" encoding="UTF-8"?><web-app xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.4" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"> <servlet> <servlet-name>dwr-invoker</servlet-name> <servlet-class>org.directwebremoting.servlet.DwrServlet</servlet-class> <init-param> <param-name>debug</param-name> <param-value>true</param-value> </init-param> </servlet> <servlet> <servlet-name>action</servlet-name> <servlet-class>org.apache.struts.action.ActionServlet</servlet-class> <init-param> <param-name>config</param-name> <param-value>/WEB-INF/struts-config.xml</param-value> </init-param> <init-param> <param-name>debug</param-name> <param-value>3</param-value> </init-param> <init-param> <param-name>detail</param-name> <param-value>3</param-value> </init-param> <load-on-startup>0</load-on-startup> </servlet> <servlet-mapping> <servlet-name>dwr-invoker</servlet-name> <url-pattern>/dwr/*</url-pattern> </servlet-mapping> <servlet-mapping> <servlet-name>action</servlet-name> <url-pattern>*.do</url-pattern> </servlet-mapping> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list></web-app>
[quote]再者是dwr.xml[/quote]
<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE dwr PUBLIC "-//GetAhead Limited//DTD Direct Web Remoting 2.0//EN" "http://www.getahead.ltd.uk/dwr/dwr20.dtd"><dwr> <allow> <convert match="com.accp.entity.Student" converter="bean"> <param name="include" value="id,username,password,age" /> </convert> <create creator="new" javascript="test"> <param name="class" value="com.accp.test.test"/> <include method="selList"/> </create> </allow> <signatures> <![CDATA[ import java.util.List; import com.accp.entity.Student; import com.accp.test.test; test.selList(List<Student>); ]]> </signatures></dwr>
[quote]然后是测试类[/quote]
package com.accp.test;import java.util.List;import org.hibernate.Transaction;import com.accp.entity.Student;import com.accp.entity.StudentDAO;public class test { /** * @param args */ public int Mytest(){ StudentDAO stuDao=new StudentDAO(); try{ Student stu=new Student(); stu.setPassword("123"); stu.setAge(22); stu.setUsername("chen"); Transaction tran=stuDao.getSession().beginTransaction(); stuDao.save(stu); tran.commit(); return 1; }catch(Exception ex){ ex.printStackTrace(); return 0; }finally{ stuDao.getSession().close(); } } public List selList(){ StudentDAO stuDao=new StudentDAO(); try{ Transaction tra=stuDao.getSession().beginTransaction(); List<Student> list=stuDao.findAll(); return list; }catch(Exception ex){ ex.printStackTrace(); return null; }finally{ stuDao.getSession().close(); } } public static void main(String[] args) { // TODO Auto-generated method stub }}和JavaBeanpackage com.accp.entity;/** * Student generated by MyEclipse Persistence Tools */public class Student implements java.io.Serializable { // Fields private Integer id; private String username; private String password; private Integer age; // Constructors /** default constructor */ public Student() { } /** minimal constructor */ public Student(String username, String password) { this.username = username; this.password = password; } /** full constructor */ public Student(String username, String password, Integer age) { this.username = username; this.password = password; this.age = age; } // Property accessors public Integer getId() { return this.id; } public void setId(Integer id) { this.id = id; } public String getUsername() { return this.username; } public void setUsername(String username) { this.username = username; } public String getPassword() { return this.password; } public void setPassword(String password) { this.password = password; } public Integer getAge() { return this.age; } public void setAge(Integer age) { this.age = age; }}
[quote]最后是jsp页面的绑定[/quote]
