spring+hibernate +struts开发问题总结

我写了一个用户注册的页面 regist.jsp 放在项目根目录下的form文件里面

? 代码如下：

<%@ page language="java" pageEncoding="utf-8"%>
<%@ taglib uri="http://struts.apache.org/tags-bean" prefix="bean"%>
<%@ taglib uri="http://struts.apache.org/tags-html" prefix="html"%>
?
<html>
?<head>
? <title>JSP for RegistForm form</title>
?</head>
?<body>
? <html:form action="/regist.do">
????? 用户名 : <html:text property="username"/>
????? <html:errors property="username"/><br/>
?? 密    码 : <html:password property="password"/>
?? <html:errors property="password"/><br/>
??
?? <html:submit value="注册"/>    
?? <html:cancel value="取消"/>
? </html:form>
?</body>
</html>

2写一个跳转页面 success.jsp和failed.jsp

3? 先搭建struts框架希望你搭建过，成功后

4 搭建hibernate框架（注意不要选默认的添加jar包，选择复制jar包) 我用的mysql数据库。

?在mysql数据库school下面建表 user

sql语句如下

CREATE TABLE `user` (
? `id` int(10) NOT NULL auto_increment,
? `username` varchar(20) NOT NULL,
? `password` varchar(20) NOT NULL,
? PRIMARY KEY? (`id`)

) ENGINE=InnoDB AUTO_INCREMENT=24 DEFAULT CHARSET=latin1;

5. 用hibernate连接数据库。

???? hibernate.cfg.xml文件如下

? <?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">

<hibernate-configuration>

?<session-factory>
? <property name="connection.username">zhxb</property>
? <property name="connection.url">
?? jdbc:mysql://localhost:3306/school
? </property>
? <property name="dialect">
?? org.hibernate.dialect.MySQLDialect
? </property>
? <property name="myeclipse.connection.profile">
?? mysql_connection
? </property>
? <property name="connection.password">zhxb</property>
? <property name="connection.driver_class">
?? com.mysql.jdbc.Driver
? </property>
?
? 
?
?? <mapping resource="springdao/User.hbm.xml" />
?</session-factory>

</hibernate-configuration>

6 搭建spring框架

?如何搭建，自己到网上找，我只说错误发生的地方和整合的地方，注意要选择复制jar包，搭建好后，

进行strut和spring的整合。

修改struts-config.xml文件：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 1.2//EN" "http://struts.apache.org/dtds/struts-config_1_2.dtd">

<struts-config>
? <data-sources />
? <form-beans >
??? <form-bean name="registForm" type="com.struts.form.RegistForm" />

? </form-beans>

? <global-exceptions />
? <global-forwards />
? <action-mappings >
? <action?

??? input="/form/regist.jsp"?

??? name="registForm"

?? path="/regist"? （注意路径）

??? scope="request"
?????? type="org.springframework.web.struts.DelegatingActionProxy">（注意这里是代理类，并不是真正的action类）
????? <forward name="failed" path="/failed.jsp" />
????? <forward name="success" path="/success.jsp" />
??? </action>
? </action-mappings>

? <message-resources parameter="com.struts.ApplicationResources" />
?<plug-in className="org.springframework.web.struts.ContextLoaderPlugIn">
??? <set-property property="contextConfigLocation" value="/WEB-INF/applicationContext.xml"/> （这个地方路径要正确）
? </plug-in>
</struts-config>

applicationContext.xml 配置如下：

<?xml version="1.0" encoding="UTF-8"?>
<beans
?xmlns="http://www.springframework.org/schema/beans"
?xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
?xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd">

??? <bean name="/regist" name="man_name" />
? </property>
?</bean>
?<bean id="transactionManager"
?class="org.springframework.orm.hibernate3.HibernateTransactionManager">
?<property name="sessionFactory">
?? <ref local="sessionFactory"/>
? </property>
?</bean>
?<bean id="UserDAOProxy"
? class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean">
? <property name="transactionManager">
? <ref bean="transactionManager"/>
?</property>
?<property name="target">
? <ref local="UserDAO"/>
?</property>
?<property name="proxyTargetClass">
?<value>true</value>
?</property>
?<property name="transactionAttributes">
?<props>
?<prop key="*">PROPAGATION_REQUIRED</prop>
???? </props>
?</property>
?</bean>
?</beans>

?action? 类中execute的代码如下

public class RegistAction extends Action {
?/*
? * Generated Methods
? */
??? private UserDAO userdao;
???? private String message="struts action is execute";
?/**
? * Method execute
? * @param mapping
? * @param form
? * @param request
? * @param response
? * @return ActionForward
? */
?public ActionForward execute(ActionMapping mapping, ActionForm form,
?? HttpServletRequest request, HttpServletResponse response) {
? RegistForm registForm = (RegistForm) form;// TODO Auto-generated method stub
? System.out.print(getMessage());
? User user=new User();
? user.setUsername(registForm.getUsername());
? user.setPassword(registForm.getPassword());
? UserDAO userdao=getUserdao();
? userdao.save(user);
? /*
? //开启事务
? Transaction tran=userdao.getSession().beginTransaction();
? userdao.save(user);
? //关闭事务
? tran.commit();
? //显示记录
? java.util.List<User> list=userdao.findAll();
? for(User o: list)
? {
?? System.out.print("用户名"+o.getUsername()+"? ");
?? System.out.println("密码"+o.getPassword());
? }
??? */
?
?return mapping.findForward("success");
?}
?public String getMessage() {
? return message;
?}
?public void setMessage(String message) {
? this.message = message;
?}
?public UserDAO getUserdao() {
? return userdao;
?}
?public void setUserdao(UserDAO userdao) {
? this.userdao = userdao;
?}
}

发生错误的地方如下

出现404错误如 action is not avilable??? 如果前面都没问题可能是包问题看你工程下面有 asm-2.2.3.jar 没有，如果有就删掉它，和asm.ja包冲突。

出现500错误或404错误，如servelt action is not avliable 时

删除项目下面的hibernate-annotations.jar包。
