Struts2+Spring+Hibernate+Maven框架整合

点击这里下载框架整合后的代码：点我下载，不要你的积分哦！！！

本文主要讲述如何通过Maven整合Struts2、Spring、Hibernate。在整合的过程中偏重于使用注解和自动装配的方式。Struts2采用的是配置文件xml的方式进行配置，Spring和Hibernate采用注解的方式进行配置。下面开始：

1、新建一个maven空程序。archetype-maven-webapp。命令：mvn archetype:generate -DarchetypeCatalog=internal

2、利用eclipse打开新建的maven程序。在pom.xml中加入需要依赖的包。

2、看一下程序中文件夹的布局

3、主要配置文件中的内容

5、jsp代码

add.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"    pageEncoding="UTF-8"%><!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"><html><head><meta http-equiv="Content-Type" content="text/html; charset=UTF-8"><title>add.jsp</title></head><body><form method="post" action="userandlog/add">姓名：<input type="text" name="name"/><br/>日志：<input type="text" name="msg"/><br/><input type="submit" value="提交"/></form></body></html>

Error.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"    pageEncoding="UTF-8"%><!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"><html><head><meta http-equiv="Content-Type" content="text/html; charset=UTF-8"><title>Insert title here</title></head><body><h1>error.jsp</h1></body></html>

Success.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"    pageEncoding="UTF-8"%><!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"><html><head><meta http-equiv="Content-Type" content="text/html; charset=UTF-8"><title>Insert title here</title></head><body><h1>success.jsp</h1></body></html>

first.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"    pageEncoding="UTF-8"%><!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"><html><head><meta http-equiv="Content-Type" content="text/html; charset=UTF-8"><title>Insert title here</title></head><body><h1>first.jsp</h1></body></html>

6、数据库表结构

user表：

-- ------------------------------ Table structure for user-- ----------------------------DROP TABLE IF EXISTS `user`;CREATE TABLE `user` (  `id` int(11) NOT NULL auto_increment,  `name` varchar(255) default NULL,  PRIMARY KEY  (`id`)) ENGINE=InnoDB AUTO_INCREMENT=12 DEFAULT CHARSET=utf8;

t_log表：

-- ------------------------------ Table structure for t_log-- ----------------------------DROP TABLE IF EXISTS `t_log`;CREATE TABLE `t_log` (  `id` int(11) NOT NULL auto_increment,  `msg` varchar(255) default NULL,  PRIMARY KEY  (`id`)) ENGINE=InnoDB AUTO_INCREMENT=9 DEFAULT CHARSET=utf8;

7、运行结果：

8、查看数据库中两个表的情况
