SpringMVC,采用的是SpringJDBC
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。

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
- <?xml version="1.0" encoding="UTF-8"?>
- <beans xmlns="http://www.springframework.org/schema/beans"
- xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"
- xsi:schemaLocation="http://www.springframework.org/schema/beans
- http://www.springframework.org/schema/beans/spring-beans-4.1.xsd
- http://www.springframework.org/schema/context
- http://www.springframework.org/schema/context/spring-context-4.1.xsd
- ">
- <!--引入配置属性文件 -->
- <context:property-placeholder location="classpath*:/applicationConfig.properties" />
- <!--扫描org.andy.work下文件,自动注入dao,entity,service为bean -->
- <context:component-scan base-package="org.andy.shop.dao.Impl,org.andy.shop.service.Impl" />
- <!-- c3p0数据源配置 -->
- <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"
- destroy-method="close">
- <property name="driverClass" value="${jdbc.driver}" />
- <property name="jdbcUrl" value="${jdbc.url}" />
- <property name="user" value="${jdbc.username}" />
- <property name="password" value="${jdbc.password}" />
- <!-- 请求超时时间 -->

- <property name="interceptorNames">
- <list>
- <value>transactionInterceptor</value>
- </list>
- </property>
- </bean>
- </beans>
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<UserInfo>, 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, PK extends Serializable> {
- T getById(PK id);
- List<T> 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<UserInfo, Integer> {
- }
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<UserInfo> findAll() {
- String sql = "SELECT * FROM user_info";
- List<UserInfo> 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<UserInfo> 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<UserInfo> 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<UserInfo> 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
- <?xml version="1.0" encoding="UTF-8"?>
- <beans xmlns="http://www.springframework.org/schema/beans"
- xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
- xmlns:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context"
- xsi:schemaLocation="http://www.springframework.org/schema/beans
- http://www.springframework.org/schema/beans/spring-beans-4.1.xsd
- http://www.springframework.org/schema/context
- http://www.springframework.org/schema/context/spring-context-4.1.xsd
- http://www.springframework.org/schema/mvc
- http://www.springframework.org/schema/mvc/spring-mvc-4.1.xsd">
- <!-- 自动扫描controller包下的所有类,如果@Controller注入为bean -->
- <context:component-scan base-package="org.andy.shop.controller" />
- <!-- 以下为SpringMVC配置 -->
- <mvc:annotation-driven>
- <!-- 返回json数据,@response使用 -->
- <mvc:message-converters register-defaults="true">
- <bean
- class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
- <property name="supportedMediaTypes">
- <list>
- <value>text/html;charset=UTF-8</value>
- <value>application/json;charset=UTF-8</value>
- </list>
- </property>
- </bean>
- </mvc:message-converters>
- </mvc:annotation-driven>
- <!-- 对模型视图名称的解析,即在模型视图名称添加前后缀 -->
- <bean
- class="org.springframework.web.servlet.view.InternalResourceViewResolver">
- <property name="viewClass"
- value="org.springframework.web.servlet.view.JstlView" />
- <property name="prefix" value="/WEB-INF/views" />
- <property name="suffix" value=".jsp" />
- </bean>
- <!-- 配置多文件上传 -->
- <bean id="multipartResolver"
- class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
- <property name="defaultEncoding">
- <value>UTF-8</value>
- </property>
- <property name="maxUploadSize">
- <!-- 上传文件大小限制为 -->
- <value>32505856</value>
- </property>
- <property name="maxInMemorySize">
- <value>4096</value>
- </property>
- </bean>
- </beans>
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<UserInfo> showUserInfos() {
- LOGGER.info("json返回全部用户的信息");
- List<UserInfo> 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 + "/";
- %>
- <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
- <html>
- <head>
- <base href="<%=basePath%>" />
- <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
- <script type="text/javascript" src="js/jquery-1.9.1.min.js"></script>
- <title>userInfo</title>
- </head>
- <body>
- 姓名: ${userInfo.uname}
- <br/>
- ajax显示全部用户信息:
- <div id="show_all_user"></div>
- </body>
- <script type="text/javascript">
- $.ajax({
- type : "get",
- url : "user/showInfos.htmls",
- dataType : "json",
- success : function(data) {
- $(data).each(
- function(i, user) {
- var p = "<p>username:" + user.uname + " unumber:"
- + user.unumber + " uregister:"
- + user.uRegisterTime + "</p>";
- $("#show_all_user").append(p);
- });
- },
- async : true
- });
- </script>
- </html>
10、配置web.xml容器
- <?xml version="1.0" encoding="UTF-8"?>
- <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
- xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
- xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
- id="WebApp_ID" version="2.5">
