基于spring2.5的采用XML配置的spring MVC项目
注:本项目全部基于XML配置。同时,集成了hibernate。采用的是:spring MVC+hibernate+spring的开发架构。
1. 建立web项目
2. 导入jar包(spring.jar, spring-webmvc.jar, commons-logging.jar。其他jar包为hibernate相关jar包)
上面是SpringMVC的所有包,我将这些jar包放在了我的百度云盘中,当然你也可以去百度搜索,下面就是正文了。。。。
下面我们先配置web.xml
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5"
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">>
<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>
</web-app>
配置说明:
- 核心控制器为org.springframework.web.servlet.DispatcherServlet
- 然后就是控制的是*.do的进行过滤,这些和Struts2的其实是一样的。
- 然后就是<init-param>里面的是Spring的配置文件
-
<
load-on-startup
>项目被加载的时候就启动他的初始化方法
-
这里的配置文件web-config.xml其实和struts2-config.xml一样的作用
下面介绍web-config.xml文件
<?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/spring-beans-2.5.xsd">

</bean>

</property>
</bean>
<bean id="userController" class="com.sxt.action.UserController">
<property name="userService" ref="userService"></property>
</bean>
</beans>
view层:包括前缀和后缀,其中后缀是说,我们返回一个如a,则后面就直接是.jsp,直接给你配置a.jsp;前缀的话,如返回的是a,则默认给你添加一个前缀为/myjsp/a.jsp,这些都是默认的
之后是service-config.xml,主要是配置业务逻辑层的bean
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

<bean id="userService" class="com.sxt.service.UserService">

dao-config.xml
<?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/spring-beans-2.5.xsd">
<bean id="userDao" class="com.sxt.dao.UserDao">
<property name="hibernateTemplate" ref="hibernateTemplate"></property>
</bean>
</beans>
包的结构为下面:
user.java
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
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;
}
}
UserService.java
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;
}
}
UserController.java 这里一般是叫controller,而且是实现controller接口
我们可以看见接口controller的实现是怎样的
其实controller是实现的HttpServletRequest和HttpServletResponse方法,很像servlet一样。
ModelAndView是MVC中的M和V就是数据和视图,比如我们跳转到ok.jsp中有页面还得有数据。
package com.sxt.action;
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;
}
}
controller层中我们返回的是new ModelAndView("index");这就对应我们之前说的前缀和后缀的问题,这里就会跳转到index.jsp中
运行测试:
http://locahost:8080/springmvc01/user.do?uname=zhangsan。
结果:数据库中增加zhangsan的记录。页面跳转到index.jsp上,显示:
