maven+springMVC+mybatis+junit详细搭建过程
springMVC+mybatis框架搭建
首先我们先要弄清搭建项目的一般流程，需要注意哪些方面，想要什么样的效果，自己的功能有哪些？
（假设效果：项目目录结构清晰，能够查询到本地数据库中的内容。。）
1. 工程目录结构整理清楚
在src/main/java文件夹中，新建包cn.springmvc.model(存放javabean),
cn.springmvc.dao（存放spring与mybatis连接接口）,
cn.springmvc.service（service接口）,
cn.springmvc.service.impl（service接口的实现），
cn.springmvc.controller（存放控制层controller）
在src/main/resource文件夹中，新建包conf（存放配置文件），
mapper（mybatis的mapper文件）
在src/test/java文件夹中，新建包cn.springmvc.test(存放测试文件)
在WEB-INF文件夹下新建jsp文件夹（存放jsp文件）
这样项目结构基本完成了
2. 引入依赖包
打开maven的pom文件，对本次开发所需使用的架包依次导入（maven项目管理的优势）
查找依赖结构有个不错的网站，http://search.maven.org/ 只要输入包名即可查找引来关系
pom.xml(包依赖)
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>eyas.springmvc</groupId> <artifactId>springmvc</artifactId> <packaging>war</packaging> <version>0.0.1-SNAPSHOT</version> <name>springmvc Maven Webapp</name> <url>http://maven.apache.org</url> <properties> <!-- spring版本号 --> <spring.version>3.2.4.RELEASE</spring.version> <!-- mybatis版本号 --> <mybatis.version>3.2.4</mybatis.version> <!-- log4j日志文件管理包版本 --> <slf4j.version>1.6.6</slf4j.version> <log4j.version>1.2.9</log4j.version> </properties> <dependencies> <!-- spring核心包 --> <!-- springframe start --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-web</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-oxm</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-tx</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aop</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context-support</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aop</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-test</artifactId> <version>${spring.version}</version> </dependency> <!-- springframe end --> <!-- mybatis核心包 --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>${mybatis.version}</version> </dependency> <!-- mybatis/spring包 --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis-spring</artifactId> <version>1.2.2</version> </dependency> <!-- mysql驱动包 --> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.29</version> </dependency> <!-- junit测试包 --> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.11</version> <scope>test</scope> </dependency> <!-- 阿里巴巴数据源包 --> <dependency> <groupId>com.alibaba</groupId> <artifactId>druid</artifactId> <version>1.0.2</version> </dependency> <!-- json数据 --> <dependency> <groupId>org.codehaus.jackson</groupId> <artifactId>jackson-mapper-asl</artifactId> <version>1.9.13</version> </dependency> <!-- 日志文件管理包 --> <!-- log start --> <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>${log4j.version}</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-api</artifactId> <version>${slf4j.version}</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-log4j12</artifactId> <version>${slf4j.version}</version> </dependency> <!-- log end --> </dependencies> <build> <finalName>springmvc</finalName> </build> </project>
3. 配置数据库连接属性
conf/ jdbc.properties（jdbc配置文件)
jdbc_driverClassName=com.mysql.jdbc.Driver jdbc_url=jdbc:mysql://localhost:3306/mydays?useUnicode=true&characterEncoding=utf-8 jdbc_username=root jdbc_password=root
4. 配置spring配置文件
conf/spring.xml(spring配置文件的扫描)
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context" 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-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd"> <!-- 引入jdbc配置文件 --> <context:property-placeholder location="classpath:conf/jdbc.properties"/> <!-- 扫描文件（自动将servicec层注入） --> <context:component-scan base-package="cn.springmvc.service"/> </beans>conf/spring-mybatis.xml（spring与mybatis连接属性）
<?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:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:util="http://www.springframework.org/schema/util" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.2.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.2.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.2.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-3.2.xsd"> <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource" init-method="init" destroy-method="close" > <property name="driverClassName"> <value>${jdbc_driverClassName}</value> </property> <property name="url"> <value>${jdbc_url}</value> </property> <property name="username"> <value>${jdbc_username}</value> </property> <property name="password"> <value>${jdbc_password}</value> </property> <!-- 连接池最大使用连接数 --> <property name="maxActive"> <value>20</value> </property> <!-- 初始化连接大小 --> <property name="initialSize"> <value>1</value> </property> <!-- 获取连接最大等待时间 --> <property name="maxWait"> <value>60000</value> </property> <!-- 连接池最大空闲 --> <property name="maxIdle"> <value>20</value> </property> <!-- 连接池最小空闲 --> <property name="minIdle"> <value>3</value> </property> <!-- 自动清除无用连接 --> <property name="removeAbandoned"> <value>true</value> </property> <!-- 清除无用连接的等待时间 --> <property name="removeAbandonedTimeout"> <value>180</value> </property> <!-- 连接属性 --> <property name="connectionProperties"> <value>clientEncoding=UTF-8</value> </property> </bean> <!-- mybatis文件配置，扫描所有mapper文件 --> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean" p:dataSource-ref="dataSource" p:configLocation="classpath:conf/mybatis-config.xml" p:mapperLocations="classpath:mapper/*.xml"/><!-- configLocation为mybatis属性 mapperLocations为所有mapper--> <!-- spring与mybatis整合配置，扫描所有dao --> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer" p:basePackage="cn.springmvc.dao" p:sqlSessionFactoryBeanName="sqlSessionFactory"/> <!-- 对数据源进行事务管理 --> <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager" p:dataSource-ref="dataSource"/> </beans> 5. java代码编写（model，dao，service层代码）
cn.springmvc.model/User.java(用户基本信息)
package cn.springmvc.model; /** * 用户表 */ public class User { private int id; private int state; private String nickname; public int getId() { return id; } public void setId(int id) { this.id = id; } public int getState() { return state; } public void setState(int state) { this.state = state; } public String getNickname() { return nickname; } public void setNickname(String nickname) { this.nickname = nickname; } }
package cn.springmvc.dao; import cn.springmvc.model.User; public interface UserDAO { /** * 添加新用户 * @param user * @return */ public int insertUser(User user); } cn.springmvc.service/UserService.java(service层接口)
package cn.springmvc.service; import cn.springmvc.model.User; public interface UserService { public int insertUser(User user); }
package cn.springmvc.service.impl; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Service; import cn.springmvc.dao.UserDAO; import cn.springmvc.model.User; import cn.springmvc.service.UserService; @Service public class UserServiceImpl implements UserService{ @Autowired private UserDAO userDAO; @Override public int insertUser(User user) { // TODO Auto-generated method stub return userDAO.insertUser(user); } }
6. mybatis配置
conf/mybatis-config.xml(mybatis配置的基本文件)
<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-config.dtd"> <configuration> <!-- 命名空间 --> <typeAliases> <typeAlias alias="User" type="cn.springmvc.model.User"/> </typeAliases> <!-- 映射map --> <mappers> </mappers> </configuration>
<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd"> <mapper namespace="cn.springmvc.dao.UserDAO"> <insert id="insertUser" parameterType="User" keyProperty="id"> insert into days_user( state, nickname) values ( #{state}, #{nickname}) </insert> </mapper>
7. junit测试插入功能
cn.springmvc.test/UserTest.java(用户测试模块)
package cn.springmvc.test; import org.junit.Before; import org.junit.Test; import org.springframework.context.ApplicationContext; import org.springframework.context.support.ClassPathXmlApplicationContext; import cn.springmvc.model.User; import cn.springmvc.service.UserService; public class UserTest { private UserService userService; @Before public void before(){ @SuppressWarnings("resource") ApplicationContext context = new ClassPathXmlApplicationContext(new String[]{"classpath:conf/spring.xml" ,"classpath:conf/spring-mybatis.xml"}); userService = (UserService) context.getBean("userServiceImpl"); } @Test public void addUser(){ User user = new User(); user.setNickname("你好"); user.setState(2); System.out.println(userService.insertUser(user)); } }
即完成插入功能！
8. springMVC模块搭建
web.xml（web功能配置）
<?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>Archetype Created Web Application</display-name> <!-- 读取spring配置文件 --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:conf/spring.xml; classpath:conf/spring-mybatis.xml </param-value> </context-param> <!-- 设计路径变量值 --> <context-param> <param-name>webAppRootKey</param-name> <param-value>springmvc.root</param-value> </context-param> <!-- Spring字符集过滤器 --> <filter> <filter-name>SpringEncodingFilter</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> <init-param> <param-name>forceEncoding</param-name> <param-value>true</param-value> </init-param> </filter> <filter-mapping> <filter-name>SpringEncodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- 日志记录 --> <context-param> <!-- 日志配置文件路径 --> <param-name>log4jConfigLocation</param-name> <param-value>classpath:conf/log4j.properties</param-value> </context-param> <context-param> <!-- 日志页面的刷新间隔 --> <param-name>log4jRefreshInterval</param-name> <param-value>6000</param-value> </context-param> <listener> <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class> </listener> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- springMVC核心配置 --> <servlet> <servlet-name>spring</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:conf/spring-mvc.xml</param-value> </init-param> <load-on-startup>2</load-on-startup> </servlet> <servlet-mapping> <servlet-name>spring</servlet-name> <url-pattern>*.do</url-pattern> </servlet-mapping> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> <!-- 错误跳转页面 --> <error-page> <!-- 路径不正确 --> <error-code>404</error-code> <location>/WEB-INF/errorpage/404.jsp</location> </error-page> <error-page> <!-- 没有访问权限，访问被禁止 --> <error-code>405</error-code> <location>/WEB-INF/errorpage/405.jsp</location> </error-page> <error-page> <!-- 内部错误 --> <error-code>500</error-code> <location>/WEB-INF/errorpage/500.jsp</location> </error-page> </web-app>

9. log4j日志记录搭建
conf/log4j.properties(日志记录的配置文件)
### set log levels ### #log4j.rootLogger = debug , stdout , D , E log4j.rootLogger = debug , stdout , D ### output to the console ### log4j.appender.stdout = org.apache.log4j.ConsoleAppender log4j.appender.stdout.Target = System.out log4j.appender.stdout.layout = org.apache.log4j.PatternLayout #log4j.appender.stdout.layout.ConversionPattern = %d{ABSOLUTE} %5p %c{ 1 }:%L - %m%n log4j.appender.stdout.layout.ConversionPattern = %-d{yyyy-MM-dd HH:mm:ss} [%c]-[%p] %m%n ### Output to the log file ### log4j.appender.D = org.apache.log4j.DailyRollingFileAppender log4j.appender.D.File = ${springmvc.root}/WEB-INF/logs/log.log log4j.appender.D.Append = true log4j.appender.D.Threshold = DEBUG log4j.appender.D.layout = org.apache.log4j.PatternLayout log4j.appender.D.layout.ConversionPattern = %-d{yyyy-MM-dd HH:mm:ss} [ %t:%r ] - [ %p ] %m%n ### Save exception information to separate file ### log4j.appender.D = org.apache.log4j.DailyRollingFileAppender log4j.appender.D.File = ${springmvc.root}/WEB-INF/logs/error.log log4j.appender.D.Append = true log4j.appender.D.Threshold = ERROR log4j.appender.D.layout = org.apache.log4j.PatternLayout log4j.appender.D.layout.ConversionPattern = %-d{yyyy-MM-dd HH:mm:ss} [ %t:%r ] - [ %p ] %m%n
10. 测试运行
WEB-INF/jsp/index.jsp(测试文件)
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>Insert title here</title> </head> <body> <h1>欢迎你！！！</h1> </body> </html>
package cn.springmvc.controller; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; @Controller @RequestMapping("/") public class UserController { @RequestMapping("index") public String index(){ return "index"; } }
将该项目部署到本地tomcat6中
右击该项目选择Run as，选择Run on Server
选择自己建立的tomcat6运行如图：
