Maven搭建SpringMVC项目详解

前言

        上一次复习搭建了SpringMVC+Mybatis，这次搭建一下SpringMVC，采用的是SpringJDBC，没有采用任何其他的ORM框架，SpringMVC提供了一整套的WEB框架，所以如果想搭建纯的SpringMVC的话，而且不必映入别的任何框架，SpringMVC都给我们提供了，下面试Spring + SpringMVC的详细搭建过程。

      项目包含：数据库mysql(其实那个数据库都无所谓)，连接池采用的是c3p0。

1、创建数据表

    数据表很简单，user_info

         

2、搭建Maven项目

     Maven项目搭建一笔带过（前面有介绍），其搭建后的webapp结构项目如下：

        

3、配置Maven的pom.xml文件

     导入所需的spring，以及数据源，spring-mvc，json等依赖。

pom.xml

4、搭建Spring

4.1、 创建配置文件，添加c3p0数据源配置信息

      src/main/resources/applicationConfig.xml

#application all config

#jdbc c3p0
jdbc.driver = com.mysql.jdbc.Driver
jdbc.url = jdbc:mysql://localhost:3306/shop?useUnicode=true&characterEncoding=utf-8
jdbc.username = root
jdbc.password = 12345

4.2、创建Spring配置文件

    src/main/resources/applicationContext.xml

   

	
	
	
	

	
	
		
		
		
		

		
		
		
		
		
		
		
		
		
		
		
		
	

	
	
		
	

	
		
	

	
	
		
	

	
	
		
		
		
			
			
			    PROPAGATION_REQUIRED
			    PROPAGATION_REQUIRED
			    PROPAGATION_REQUIRED
			    
				PROPAGATION_SUPPORTS,readOnly
				PROPAGATION_SUPPORTS,readOnly
				PROPAGATION_REQUIRED
			
		
	

	
	
		
		
			
				*Service
			
		
		
		
			
				transactionInterceptor
			
		
	

  上面配置的详细功能已写出。

4.3、添加Log4j日志配置

    src/main/resources/log4j.properties

  

### set log levels ###
log4j.rootLogger = INFO , C , D , E 

### console ###
log4j.appender.C = org.apache.log4j.ConsoleAppender
log4j.appender.C.Target = System.out
log4j.appender.C.layout = org.apache.log4j.PatternLayout
log4j.appender.C.layout.ConversionPattern = [springmvc_demo][%p] [%-d{yyyy-MM-dd HH:mm:ss}] %C.%M(%L) | %m%n

### log file ###
log4j.appender.D = org.apache.log4j.DailyRollingFileAppender
log4j.appender.D.File = ../logs/springmvc-mybatis-demo.log
log4j.appender.D.Append = true
log4j.appender.D.Threshold = INFO 
log4j.appender.D.layout = org.apache.log4j.PatternLayout
log4j.appender.D.layout.ConversionPattern = [springmvc_demo][%p] [%-d{yyyy-MM-dd HH:mm:ss}] %C.%M(%L) | %m%n

### exception ###
log4j.appender.E = org.apache.log4j.DailyRollingFileAppender
log4j.appender.E.File = ../logs/springmvc-mybatis-demo_error.log 
log4j.appender.E.Append = true
log4j.appender.E.Threshold = ERROR 
log4j.appender.E.layout = org.apache.log4j.PatternLayout
log4j.appender.E.layout.ConversionPattern = [springmvc_demo][%p] [%-d{yyyy-MM-dd HH:mm:ss}] %C.%M(%L) | %m%n

5、Entity，Dao，Service实现

创建如下包：

      

5.1、entity创建UserInfo实体

org.andy.shop.entity中添加

package org.andy.shop.entity;

import java.io.Serializable;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.util.Date;

import org.springframework.jdbc.core.RowMapper;

/**
 * 实现数据表与字段的映射
 * 
 * @author andy
 * 
 */
public class UserInfo implements RowMapper, Serializable {

	/**
	 * 
	 */
	private static final long serialVersionUID = -8823504831198719837L;

	private Integer id;

	private String uname;

	private Integer unumber;

	private Date uRegisterTime;

	public Integer getId() {
		return id;
	}

	public void setId(Integer id) {
		this.id = id;
	}

	public String getUname() {
		return uname;
	}

	public void setUname(String uname) {
		this.uname = uname == null ? null : uname.trim();
	}

	public Integer getUnumber() {
		return unumber;
	}

	public void setUnumber(Integer unumber) {
		this.unumber = unumber;
	}

	public Date getuRegisterTime() {
		return uRegisterTime;
	}

	public void setuRegisterTime(Date uRegisterTime) {
		this.uRegisterTime = uRegisterTime;
	}

	@Override
	public UserInfo mapRow(ResultSet rs, int rowNum) throws SQLException {
		UserInfo userInfo = new UserInfo();
		userInfo.setId(rs.getInt("id"));
		userInfo.setUname(rs.getString("uname"));
		userInfo.setUnumber(rs.getInt("unumber"));
		userInfo.setuRegisterTime(rs.getDate("uregister_time"));
		return userInfo;
	}

}

实现RowMapper接口是为了方便SpringJDBC管理实体与数据库字段的映射。

5.2、实现Dao层

  org.andy.shop.dao添加通用Dao接口

 GenericDao.java:

package org.andy.shop.dao;

import java.io.Serializable;
import java.util.List;

/**
 * 创建时间：2015-1-30 上午10:11:59
 * 
 * @author andy
 * @version 2.2
 * 
 * Dao通用接口
 */

interface GenericDao {

	T getById(PK id);

	List findAll();

	PK save(T entity);
}

 添加UserInfoDao.java

package org.andy.shop.dao;

import org.andy.shop.entity.UserInfo;

/**
 * 创建时间：2015-1-30 上午11:22:37
 * 
 * @author andy
 * @version 2.2
 * 
 * UserInfoDao
 */

public interface UserInfoDao extends GenericDao {

}

  在org.andy.shop.dao.Impl包中添加UserInfoDao的Dao实现类

  UserInfoDaoImpl.java

 

package org.andy.shop.dao.Impl;

import java.util.List;

import org.andy.shop.dao.UserInfoDao;
import org.andy.shop.entity.UserInfo;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jdbc.core.JdbcTemplate;
import org.springframework.jdbc.core.namedparam.MapSqlParameterSource;
import org.springframework.jdbc.core.namedparam.NamedParameterJdbcTemplate;
import org.springframework.stereotype.Repository;

/**
 * 创建时间：2015-1-30 上午11:25:30
 * 
 * @author andy
 * @version 2.2
 * 
 * UserInfoDao实现类
 */
@Repository("userInfoDao")
public class UserInfoDaoImpl implements UserInfoDao {

	@Autowired
	private JdbcTemplate jdbcTemplate;

	@Autowired
	private NamedParameterJdbcTemplate namedParameterJdbcTemplate;

	@Override
	public UserInfo getById(Integer id) {

		String sql = "SELECT * FROM user_info WHERE id = ?";

		UserInfo userInfo = jdbcTemplate.queryForObject(sql, new UserInfo(),
				new Object[] { id });

		return userInfo;
	}

	@Override
	public List findAll() {
		String sql = "SELECT * FROM user_info";
		List userInfos = jdbcTemplate.query(sql, new UserInfo());
		return userInfos;
	}

	@Override
	public Integer save(UserInfo entity) {
		
		String sql = "INSERT INTO user_info(uname, unumber, uregister_time) VALUES(:uname, :unumber, :uregister_time)";
		MapSqlParameterSource paramSource = new MapSqlParameterSource();
		paramSource.addValue("uname", entity.getUname());
		paramSource.addValue("unumber", entity.getUnumber());
		paramSource.addValue("uregister_time", entity.getuRegisterTime());
		int result = namedParameterJdbcTemplate.update(sql, paramSource);
		
		return result;
	}

}

5.3、实现Service层

  org.andy.shop.dao.service添加UserInfoService接口

  UserInfoService.java

 

package org.andy.shop.service;

import java.util.List;
import org.andy.shop.entity.UserInfo;

/**
 * 创建时间：2015-1-30 上午11:31:34
 * 
 * @author andy
 * @version 2.2
 * 
 * UserInfoService 接口
 */

public interface UserInfoService {

	// 通过Id查询UserInfo
	UserInfo getById(Integer id);

	// 查询全部的UserInfo
	List findAll();

	// 添加UserInfo
	Integer save(UserInfo userInfo);

}

   实现UserInfoService接口

 

package org.andy.shop.service.Impl;

import java.util.List;

import org.andy.shop.dao.UserInfoDao;
import org.andy.shop.entity.UserInfo;
import org.andy.shop.service.UserInfoService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

/**
 * 创建时间：2015-1-30 上午11:40:19
 * 
 * @author andy
 * @version 2.2 实现接口
 */

@Service("userInfoService")
public class UserInfoServiceImpl implements UserInfoService {

	@Autowired
	private UserInfoDao userInfoDao;

	@Override
	public UserInfo getById(Integer id) {
		return userInfoDao.getById(id);
	}

	@Override
	public List findAll() {
		return userInfoDao.findAll();
	}

	@Override
	public Integer save(UserInfo userInfo) {
		return userInfoDao.save(userInfo);
	}

}

6、测试Spring搭建

     单元测试Service中的方法，如果全部成功，Spring和数据连接池搭建完成。

   

package org.andy.shop.test.service;

import java.util.Date;
import java.util.List;

import org.andy.shop.entity.UserInfo;
import org.andy.shop.service.UserInfoService;
import org.apache.log4j.Logger;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

import com.alibaba.fastjson.JSON;

/**
 * 创建时间：2015-1-30 下午12:01:47
 * 
 * @author andy
 * @version 2.2
 */
// 引入Spring环境测试
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "classpath:applicationContext.xml" })
public class TestUserInfoService {

	private static final Logger LOGGER = Logger
			.getLogger(TestUserInfoService.class);
	@Autowired
	private UserInfoService userInfoService;

	@Test
	public void testGetById() {
		//测试查询对应的用户
		UserInfo userInfo = userInfoService.getById(1);
		LOGGER.info(JSON.toJSONStringWithDateFormat(userInfo,
				"yyyy-MM-dd HH:mm:ss"));
	}

	@Test
	public void testFindAll() {
		//测试查询全部用户
		List userInfos = userInfoService.findAll();
		for (UserInfo userInfo : userInfos) {
			LOGGER.info(JSON.toJSONStringWithDateFormat(userInfo,
					"yyyy-MM-dd HH:mm:ss"));
		}
	}

	@Test
	public void testSave() {
		//测试保存用户数据
		UserInfo userInfo = new UserInfo();
		userInfo.setUname("xiaohonghong");
		userInfo.setUnumber(5);
		userInfo.setuRegisterTime(new Date());
		int result = userInfoService.save(userInfo);
		LOGGER.info("result = " + result);
	}
}

7、搭建SpringMVC

    src/main/resources/springMVC.xml

   

	
	
	
	
	    
		
			
				
					
						text/html;charset=UTF-8
						application/json;charset=UTF-8
					
				

			
		
	

	
	
		
		
		
	

	
	
		
			UTF-8
		
		
			
			32505856
		
		
			4096
		
	

8、控制层Controller

  添加UserInfoController控制层

package org.andy.shop.controller;

import java.util.List;

import org.andy.shop.entity.UserInfo;
import org.andy.shop.service.UserInfoService;
import org.apache.log4j.Logger;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

/**
 * 创建时间：2015-2-1 下午9:40:03
 * 
 * @author andy
 * @version 2.2
 * 
 * userInfo的控制层
 */
@Controller
@RequestMapping("/user")
public class UserInfoController {

	private static final Logger LOGGER = Logger
			.getLogger(UserInfoController.class);
	@Autowired
	private UserInfoService userInfoService;

	@RequestMapping("/showInfo/{userId}")
	public String showUserInfo(ModelMap modelMap, @PathVariable int userId) {
		LOGGER.info("查看用户：" + userId);
		UserInfo userInfo = userInfoService.getById(1);
		modelMap.addAttribute("userInfo", userInfo);
		return "/user/showInfo";
	}

	@RequestMapping("/showInfos")
	public @ResponseBody List showUserInfos() {
		LOGGER.info("json返回全部用户的信息");
		List userInfos = userInfoService.findAll();
		return userInfos;
	}
}

9、视图层

  在webapp/WEB-INF/views/user中创建showInfo.jsp文件。

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>

<%
	String path = request.getContextPath();
	String basePath = request.getScheme() + "://"
			+ request.getServerName() + ":" + request.getServerPort()
			+ path + "/";
%>









	姓名： ${userInfo.uname} 
	

	ajax显示全部用户信息：
	

10、配置web.xml容器

	springmvc_demo

    
		contextConfigLocation
		classpath*:/applicationContext.xml
	

	
		encodingFilter
		org.springframework.web.filter.CharacterEncodingFilter
		
			encoding
			utf-8
		
		
			forceEncoding
			true
		
	
	
		encodingFilter
		/*
	

	
	  
		org.springframework.web.context.ContextLoaderListener
	

	
	
		org.springframework.web.util.IntrospectorCleanupListener
	

	
		spring mvc servlet
		rest
		org.springframework.web.servlet.DispatcherServlet
		
			contextConfigLocation
			
			classpath*:/springMVC.xml
		
		1
	

	
		rest
		*.htmls
	

	
	
		30
	

	
		/index.jsp
	

11、测试项目

   maven编译打包部署到tomcat，测试：http://localhost:8080/springmvc_demo/user/showInfo/1.htmls分别测试添加的两个请求地址。

至此，SpringMVC搭建完毕。
