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

   

<?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="checkoutTimeout" value="30000" />
<!-- 每60秒检查所有连接池中的空闲连接。默认值: 0，不检查 -->
<property name="idleConnectionTestPeriod" value="30" />
<!-- 连接数据库连接池最大空闲时间 -->
<property name="maxIdleTime" value="30" />
<!-- 连接池初始化连接数 -->
<property name="initialPoolSize" value="5" />
<property name="minPoolSize" value="5" />
<property name="maxPoolSize" value="20" />
<!--当连接池中的连接耗尽的时候c3p0一次同时获取的连接数。默认值: 3 -->
<property name="acquireIncrement" value="5" />
</bean>

<!-- spring jdbc -->
<bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate">
<property name="dataSource" ref="dataSource" />
</bean>

<bean id="namedParameterJdbcTemplate"
class="org.springframework.jdbc.core.namedparam.NamedParameterJdbcTemplate">
<constructor-arg ref="dataSource" />
</bean>

<!-- 配置事务管理 -->
<bean id="transactionManager"
class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource" />
</bean>

<!-- 声明式事务，事务拦截器 -->
<bean id="transactionInterceptor"
class="org.springframework.transaction.interceptor.TransactionInterceptor">
<property name="transactionManager" ref="transactionManager" />
<!-- 配置事务属性 -->
<property name="transactionAttributes">
<!--下面定义事务传播属性 -->
<props>
<prop key="save*">PROPAGATION_REQUIRED</prop>
<prop key="del*">PROPAGATION_REQUIRED</prop>
<prop key="update">PROPAGATION_REQUIRED</prop>

<prop key="get*">PROPAGATION_SUPPORTS,readOnly</prop>
<prop key="find*">PROPAGATION_SUPPORTS,readOnly</prop>
<prop key="*">PROPAGATION_REQUIRED</prop>
</props>
</property>
</bean>

<!-- Bean后处理器BeanNameAutoProxyCreator，根据List配置创建事务代理 -->
<bean
class="org.springframework.aop.framework.autoproxy.BeanNameAutoProxyCreator">
<!-- 下面是所有需要自动创建事务代理的bean -->
<property name="beanNames">
<list>
<value>*Service</value>
</list>
</property>
<!-- 下面定义BeanNameAutoProxyCreator所需的事务拦截器 -->
<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">

<display-name>springmvc_demo</display-name>

<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath*:/applicationContext.xml</param-value>
</context-param>

<filter>

<url-pattern>/*</url-pattern>
</filter-mapping>

<!-- 监听servletContext，启动contextConfigLocation中的spring配置信息 -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

<!-- 防止spring内存溢出监听器 -->
<listener>
<listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class>
</listener>

<servlet>
<description>spring mvc servlet</description>
<servlet-name>rest</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<!-- 此处配置的是SpringMVC的配置文件 -->
<param-value>classpath*:/springMVC.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
<servlet-name>rest</servlet-name>
<url-pattern>*.htmls</url-pattern>
</servlet-mapping>

<!-- 配置session超时时间，单位分钟 -->
<session-config>
<session-timeout>30</session-timeout>
</session-config>

<welcome-file-list>
<welcome-file>/index.jsp</welcome-file>
</welcome-file-list>
