新手研究spring mvc框架

 

      大家好，刚把javaee学完，接着趁热打铁学框架，这是我搭建的一个spring框架，搭的不好的地方请大家指点，，我用的spring2.5的jar，听说这个版本比较稳定，下面介绍我的框架是怎么搭建的

 

1.新建一个web工程，工程名称是spring

2.导入相应的springjar文件

3.在src目录下建立相应的包

(1)

 com.spring.dao 新建一个MemberDao接口

 

package com.spring.dao;

import java.util.List;

import com.spring.model.MembersModel;

/**
 * @author Administrator
 *
 */
public interface MemberDao {

	/**
	 * 获取所有用户列表
	 * @return
	 */
	public List<MembersModel> findAllMembersModels();
}

 

 com.spring.dao.imp 新建一个MemberDaoImpl 实现类

 

package com.spring.dao.impl;

import java.util.List;

import org.springframework.jdbc.core.simple.SimpleJdbcDaoSupport;

import com.spring.dao.MemberDao;
import com.spring.model.MembersModel;

/**
 * @author Administrator
 *
 */
public class MemberDaoImpl extends SimpleJdbcDaoSupport implements MemberDao {

	/* (non-Javadoc)
	 * @see com.spring.MemberDao#findAllMembersModels()
	 */
	public List<MembersModel> findAllMembersModels() {
		// 去数据库里查询
		//sql....
		return null;
	}

}

 

 com.spring.dao.model 新建一个MembersModel类

package com.spirng.model;

/**
 * @author Administrator
 *
 */
public class MembersModel {
	private String id ;
	private String logonname;
	private String logonpassword;
	
	public MembersModel(){

	}
	
	public MembersModel(String id,String logonname,String logonpassword){
		this.id=id;
		this.logonname=logonname;
		this.logonpassword=logonpassword;
	}
	public String getLogonpassword() {
		return logonpassword;
	}
	public void setLogonpassword(String logonpassword) {
		this.logonpassword = logonpassword;
	}
	public String getId() {
		return id;
	}
	public void setId(String id) {
		this.id = id;
	}
	public String getLogonname() {
		return logonname;
	}
	public void setLogonname(String logonname) {
		this.logonname = logonname;
	}
}

 

 

 com.spring.service 新建一个MemberService接口

package com.spring.service;

import java.util.List;

import com.spring.model.MembersModel;

/**
 * @author Administrator
 *
 */
public interface MemberService {
	/**
	 * 返回所有用户列表
	 * @return 用户列表
	 */
	public List<MembersModel> findAllMembersModels();
}

 

 com.spring.service.impl 新建一个MemberServiceImpl实现类

package com.spring.service.impl;

import java.util.List;

import com.spring.dao.MemberDao;
import com.spring.model.MembersModel;
import com.spring.service.MemberService;

/**
 * @author Administrator
 *
 */
public class MemberServiceImpl implements MemberService {
	
	private MemberDao memberDao;
	

	public void setMemberDao(MemberDao memberDao) {
		this.memberDao = memberDao;
	}


	/* (non-Javadoc)
	 * @see com.spring.service.MemberService#findAllMembersModels()
	 */
	public List<MembersModel> findAllMembersModels() {
		// TODO Auto-generated method stub
		return memberDao.findAllMembersModels();
	}

}

 

 com.spring.web.controller 新建一个MemberController 控制类

 

package com.spring.web.controller;

import java.util.ArrayList;
import java.util.List;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.web.bind.ServletRequestBindingException;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.multiaction.MultiActionController;

import com.spring.model.MembersModel;
import com.spring.service.MemberService;

/**
 * @author Administrator
 *
 */
public class MemberController extends MultiActionController {

	private MemberService memberService;
	
	
	
	public void setMemberService(MemberService memberService) {
		this.memberService = memberService;
	}



	public ModelAndView memberList(HttpServletRequest request,HttpServletResponse response) throws ServletRequestBindingException{
		//查询数据库了
		
		List<MembersModel> list = memberService.findAllMembersModels();
	
		
		return new ModelAndView("MemberList").addObject("memberlist", list);
	}
}

 

以上就是我src下的结构，遵循spring的mvc模式

 

4.修改web.xml文件，进行相应的配置

 

<?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">
	<welcome-file-list>
		<welcome-file>index.jsp</welcome-file>
	</welcome-file-list>
    <!--对WEB-INF下的xml文件进行整合，本来spring就一个配置文件，但是为了可读性，我把他分开了-->
	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>/WEB-INF/spring-*.xml</param-value>
	</context-param>

	<listener>
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>


<!-- 把所以页面的字符编码转换成utf-8 -->
	<filter>
		<filter-name>encodingFilter</filter-name>
		<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
		<init-param>
			<param-name>encoding</param-name>
			<param-value>utf-8</param-value>
		</init-param>
	</filter>
	<filter-mapping>
		<filter-name>encodingFilter</filter-name>
		<url-pattern>/*</url-pattern>
	</filter-mapping>

<!-- 一个页面请求控制器，相当于struts的web.xml的拦截器 -->
	<servlet>
		<servlet-name>court</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
		<load-on-startup>1</load-on-startup>
	</servlet>
	<servlet-mapping>
		<servlet-name>court</servlet-name>
		<url-pattern>*.htm</url-pattern>
	</servlet-mapping>

</web-app>

 

5.在WEB-INF下配置spring的配置文件

为了增强配置文件的可读性，新生容易理解一点，我这里把配置文件分开了,有些配置文件是空的，主要为了以后业务拓展

(1)Copy of court-servlet.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 http://www.springframework.org/schema/beans/spring-beans-2.5.xsd"
	   default-autowire="byName">
	
	
	
	<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">

 7.部署工程，进行测试
