注&＃xff1a;
/&＃xff1a; 会匹配到 /springmvc 这样的路径型url&＃xff0c;而不会匹配到像 .jsp 这样的后缀型的url。
/*&＃xff1a;会匹配到所有的url&＃xff1a;路径型url 和后缀型的url &＃xff08;包括/springmvc,.jsp,.js,和.html等&＃xff09;。

**注&＃xff1a;**需要c3p0的jar包。c3p0-0.9.2.1.jar、hibernate-c3p0-5.0.7.Final.jar、mchange-commons-java-0.2.3.4.jar。数据库驱动包就更不用说了。没有的话可以去Maven仓库下。

配置文件目录&＃xff1a;

注&＃xff1a;
在Spring的配置里&＃xff0c;最好不要配置xsd文件的版本号。Spring默认在启动时是要加载XSD文件来验证xml文件的&＃xff0c;所以如果有的时候断网了&＃xff0c;或者网络不好&＃xff0c;就会出现问题。为了防止这种情况&＃xff0c;Spring提供了一种机制&＃xff0c;默认从本地加载XSD文件。所以当我们没有配置xsd文件的版本号的时候&＃xff0c;用的就是当前版本的XSD文件。

至此基本配置都配好了。我们来测试一下&＃xff1a;
testDao.java

package test.dao;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;
import entity.Admin;
&＃64;Repository
public class testDao {&＃64;Autowiredprivate SessionFactory sessionFactory; public SessionFactory getSessionFactory() { return sessionFactory; } private Session getSession() {return sessionFactory.getCurrentSession();}public Admin getAdmin(int id) {Admin admin &＃61; (Admin)this.getSession().get(Admin.class, id);return admin;}
}

testService.java

package test.service;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
import entity.Admin;
import test.dao.testDao;
&＃64;Service
&＃64;Transactional
public class testService {&＃64;Autowired
private testDao testDao;
public Admin getAdmin(int id) {return testDao.getAdmin(id);
}
}

testController.java

package test.controller;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import entity.Admin;
import test.service.testService;
&＃64;Controller
public class testController {
&＃64;Autowired
private testService testService;
&＃64;RequestMapping("/test")
public String test()
{int id &＃61; 2;Admin admin &＃61; testService.getAdmin(id);System.out.println(admin.getAdminname());return "success";
}
}

success.jsp

<%&＃64; page language&＃61;"java" contentType&＃61;"text/html; charset&＃61;UTF-8"
pageEncoding&＃61;"UTF-8"%>







查询成功



跳转的成功页面

查询出的Adminname

最终项目目录结构

Spring推荐使用接口编程解耦&＃xff0c;不过我这里没有用。因为感觉要创建好多个类啊。。偷懒喽
