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。

建立web项目
导入jar包(spring.jar, spring-webmvc.jar, commons-logging.jar。其他jar包为hibernate相关jar包)

修改web.xml如下：

<?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>

增加web-config.xml(这里包含spring mvc相关的相关配置)

<?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-2.5.xsd">
    
    <!-- Controller方法调用规则定义 -->
    <bean id="paraMethodResolver"
        class="org.springframework.web.servlet.mvc.multiaction.ParameterMethodNameResolver">
        <property name="paramName" value="action"/>
        <property name="defaultMethodName" value="list"/>
    </bean>
  
   <!-- 页面View层基本信息设定 -->
    <bean id="viewResolver"
          class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="viewClass"
            value="org.springframework.web.servlet.view.JstlView"/>
        <!--<property name="prefix" value="/myjsp/"/>-->
        <property name="suffix" value=".jsp"/>
    </bean>

<!-- servlet映射列表,所有控制层Controller的servlet在这里定义 -->
    <bean id="urlMapping"
          class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
        <property name="mappings">
            <props>
                <prop key="user.do">userController</prop>
            </props>
        </property>
    </bean>

<bean id="userController" class="com.sxt.action.UserController">
    <property name="userService" ref="userService"></property>
</bean>
</beans>

在WEB-INF下增加service-config.xml(这里包含service层类的相关配置)

<?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>

在WEB-INF下增加hib-config.xml(这里包含spring集成hibernate相关的配置)

<?xml version="1.0" encoding="UTF-8"?>

在WEB-INF下增加dao-config.xml(这里包含dao层类的相关配置)

<?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>

建立相关类和包结构，如下图所示：

各类代码：

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;
    }
}
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;
    }
    
}
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;
    }
    
}
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;
    }

    
}

1. 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

package com.sxt.po;

import javax.persistence.Entity;

import javax.persistence.GeneratedValue;

import javax.persistence.GenerationType;

import javax.persistence.Id;

@Entity

publicclass User {

@Id

@GeneratedValue(strategy=GenerationType.AUTO)

privateintid;

private String uname;

publicint getId() {

returnid;

}

publicvoid setId(int id) {

this.id = id;

}

public String getUname() {

returnuname;

}

publicvoid setUname(String uname) {

this.uname = uname;

}

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;

}

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;

}

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;

}
