Maven搭建SpringMVC项目详解
前言
https://blog.****.net/doc_wei/article/details/52942547
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 -

"> -
<!--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" -

<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> -
</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"?> -
