这个一个springMVC添加用户的demo！其中项目目录结构如下：
其中User.java中的内容如下：
package com.sxt.po;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
@Entity
public class User {
@Id
@GeneratedValue(strategy=GenerationType.AUTO)
private int id;
private String uname;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getUname() {
return uname;
}
public void setUname(String uname) {
this.uname = uname;
}
}
UserDao.java中的内容为：
package com.sxt.dao;
import org.springframework.orm.hibernate3.HibernateTemplate;
import com.sxt.po.User;
public class UserDao {
private HibernateTemplate hibernateTemplate;
public void add(User u){
System.out.println("UserDao.add()");
hibernateTemplate.save(u);
}
public HibernateTemplate getHibernateTemplate() {
return hibernateTemplate;
}
public void setHibernateTemplate(HibernateTemplate hibernateTemplate) {
this.hibernateTemplate = hibernateTemplate;
}
}
然后UserService.java中的文件如下：
package com.sxt.service;
import com.sxt.dao.UserDao;
import com.sxt.po.User;
public class UserService {
private UserDao userDao;
public void add(String uname){
System.out.println("UserService.add()");
User u = new User();
u.setUname(uname);
userDao.add(u);
}
public UserDao getUserDao() {
return userDao;
}
public void setUserDao(UserDao userDao) {
this.userDao = userDao;
}
}
然后UserController.java中的文件如下：
package com.sxt.controller;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.Controller;
import com.sxt.service.UserService;
public class UserController implements Controller {
private UserService userService;
@Override
public ModelAndView handleRequest(HttpServletRequest req,
HttpServletResponse resp) throws Exception {
System.out.println("HelloController.handleRequest()");
req.setAttribute("a", "aaaa");
userService.add(req.getParameter("uname"));
return new ModelAndView("index");
}
public UserService getUserService() {
return userService;
}
public void setUserService(UserService userService) {
this.userService = userService;
}
}
到此我们bean的实体和业务逻辑已经完成，接下俩进行springMVC的配置，springMVC为了便于管理，将applicationContext.xml文件分解成了若干个.xml文件，有dao-config.xml
hib-config.xml(hibernate配置文件)
service-config.xml
web-config.xml
它们的文件内容具体如下：
dao-config.xml内容如下：
<?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="

<bean id="userDao" class="com.sxt.dao.UserDao">
<property name="hibernateTemplate" ref="hibernateTemplate"></property>
</bean>
</beans>
service-config.xml中的内容如下：
<?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="

<bean id="userService" class="com.sxt.service.UserService">
<property name="userDao" ref="userDao"></property>
</bean>
</beans>
hib-config.xml内容如下：
<?xml version="1.0" encoding="UTF-8"?>

web-config.xml中的内容如下：

</property>
</bean>
<bean id="userController" class="com.sxt.controller.UserController">
<property name="userService" ref="userService"></property>
</bean>
</beans>
最后不要忘记在web.xml中配置springmvc的dispatcher环境：
<!-- 配置springMVC环境 -->
<servlet>
<servlet-name>dispatcherServlet</servlet-name>
<servlet-class>
org.springframework.web.servlet.DispatcherServlet
</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/hib-config.xml,/WEB-INF/web-config.xml,/WEB-INF/service-config.xml,/WEB-INF/dao-config.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>dispatcherServlet</servlet-name>
<url-pattern>*.do</url-pattern>
</servlet-mapping>
到此springMVC的添加小案例完成，将项目部署在服务器中，在浏览器键入http://localhost:9090/springmvc_01/user.do?uname=wangwu，此时我们可以发现数据库myhb中新建了一张User表，插入了数据name为"wangwu"的一条数据！
