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)

<projectxmlns="http://maven.apache.org/POM/4.0.0"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0http://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>springmvcMavenWebapp</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--> <!--springframestart--> <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> <!--springframeend--> <!--mybatis核心包--> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>${mybatis.version}</version> </dependency> <!--mybatis/spring包--> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis-spring</artifactId> <version>1.2.2</version> </dependency> <!--mysql驱动包--> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.29</version> </dependency> <!--junit测试包--> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.11</version> <scope>test</scope> </dependency> <!--阿里巴巴数据源包--> <dependency> <groupId>com.alibaba</groupId> <artifactId>druid</artifactId> <version>1.0.2</version> </dependency> <!--json数据--> <dependency> <groupId>org.codehaus.jackson</groupId> <artifactId>jackson-mapper-asl</artifactId> <version>1.9.13</version> </dependency> <!--日志文件管理包--> <!--logstart--> <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>${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> <!--logend--> </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)

<?xmlversion="1.0"encoding="UTF-8"?> <beansxmlns="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/beanshttp://www.springframework.org/schema/beans/spring-beans-3.0.xsdhttp://www.springframework.org/schema/contexthttp://www.springframework.org/schema/context/spring-context.xsd"> <!--引入jdbc配置文件--> <context:property-placeholderlocation="classpath:conf/jdbc.properties"/> <!--扫描文件（自动将servicec层注入）--> <context:component-scanbase-package="cn.springmvc.service"/> </beans>
conf/spring-mybatis.xml（spring与mybatis连接属性）

<?xmlversion="1.0"encoding="UTF-8"?> <beansxmlns="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/beanshttp://www.springframework.org/schema/beans/spring-beans-3.2.xsdhttp://www.springframework.org/schema/contexthttp://www.springframework.org/schema/context/spring-context-3.2.xsdhttp://www.springframework.org/schema/txhttp://www.springframework.org/schema/tx/spring-tx-3.2.xsdhttp://www.springframework.org/schema/aophttp://www.springframework.org/schema/aop/spring-aop-3.2.xsdhttp://www.springframework.org/schema/utilhttp://www.springframework.org/schema/util/spring-util-3.2.xsd"> <beanid="dataSource"class="com.alibaba.druid.pool.DruidDataSource"init-method="init" destroy-method="close"> <propertyname="driverClassName"> <value>${jdbc_driverClassName}</value> </property> <propertyname="url"> <value>${jdbc_url}</value> </property> <propertyname="username"> <value>${jdbc_username}</value> </property> <propertyname="password"> <value>${jdbc_password}</value> </property> <!--连接池最大使用连接数--> <propertyname="maxActive"> <value>20</value> </property> <!--初始化连接大小--> <propertyname="initialSize"> <value>1</value> </property> <!--获取连接最大等待时间--> <propertyname="maxWait"> <value>60000</value> </property> <!--连接池最大空闲--> <propertyname="maxIdle"> <value>20</value> </property> <!--连接池最小空闲--> <propertyname="minIdle"> <value>3</value> </property> <!--自动清除无用连接--> <propertyname="removeAbandoned"> <value>true</value> </property> <!--清除无用连接的等待时间--> <propertyname="removeAbandonedTimeout"> <value>180</value> </property> <!--连接属性--> <propertyname="connectionProperties"> <value>clientEncoding=UTF-8</value> </property> </bean> <!--mybatis文件配置，扫描所有mapper文件--> <beanid="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--> <beanclass="org.mybatis.spring.mapper.MapperScannerConfigurer" p:basePackage="cn.springmvc.dao" p:sqlSessionFactoryBeanName="sqlSessionFactory"/> <!--对数据源进行事务管理--> <beanid="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)

packagecn.springmvc.model; /** *用户表 */ publicclassUser{ privateintid; privateintstate; privateStringnickname; publicintgetId(){ returnid; } publicvoidsetId(intid){ this.id=id; } publicintgetState(){ returnstate; } publicvoidsetState(intstate){ this.state=state; } publicStringgetNickname(){ returnnickname; } publicvoidsetNickname(Stringnickname){ this.nickname=nickname; } }

cn.springmvc.dao/UserDAO.java(dao操作接口)

packagecn.springmvc.dao; importcn.springmvc.model.User; publicinterfaceUserDAO{ /** *添加新用户 *@paramuser *@return */ publicintinsertUser(Useruser); }
cn.springmvc.service/UserService.java(service层接口)

packagecn.springmvc.service; importcn.springmvc.model.User; publicinterfaceUserService{ publicintinsertUser(Useruser); }

cn.springmvc.service.impl/UserServiceImpl.java(service层接口实现)

packagecn.springmvc.service.impl; importorg.springframework.beans.factory.annotation.Autowired; importorg.springframework.stereotype.Service; importcn.springmvc.dao.UserDAO; importcn.springmvc.model.User; importcn.springmvc.service.UserService; @Service publicclassUserServiceImplimplementsUserService{ @Autowired privateUserDAOuserDAO; @Override publicintinsertUser(Useruser){ //TODOAuto-generatedmethodstub returnuserDAO.insertUser(user); } }

6.mybatis配置

conf/mybatis-config.xml(mybatis配置的基本文件)

<?xmlversion="1.0"encoding="UTF-8"?> <!DOCTYPEconfiguration PUBLIC"-//mybatis.org//DTDConfig3.0//EN" "http://mybatis.org/dtd/mybatis-3-config.dtd"> <configuration> <!--命名空间--> <typeAliases> <typeAliasalias="User"type="cn.springmvc.model.User"/> </typeAliases> <!--映射map--> <mappers> </mappers> </configuration>

mapper/UserMapper.xml(mybatis的实现)

<?xmlversion="1.0"encoding="UTF-8"?> <!DOCTYPEmapper PUBLIC"-//mybatis.org//DTDMapper3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd"> <mappernamespace="cn.springmvc.dao.UserDAO"> <insertid="insertUser"parameterType="User"keyProperty="id"> insertintodays_user( state, nickname) values ( #{state}, #{nickname}) </insert> </mapper>

这样就完成了基本插入用户的功能！

7.junit测试插入功能

cn.springmvc.test/UserTest.java(用户测试模块)

packagecn.springmvc.test; importorg.junit.Before; importorg.junit.Test; importorg.springframework.context.ApplicationContext; importorg.springframework.context.support.ClassPathXmlApplicationContext; importcn.springmvc.model.User; importcn.springmvc.service.UserService; publicclassUserTest{ privateUserServiceuserService; @Before publicvoidbefore(){ @SuppressWarnings("resource") ApplicationContextcontext=newClassPathXmlApplicationContext(newString[]{"classpath:conf/spring.xml" ,"classpath:conf/spring-mybatis.xml"}); userService=(UserService)context.getBean("userServiceImpl"); } @Test publicvoidaddUser(){ Useruser=newUser(); user.setNickname("你好"); user.setState(2); System.out.println(userService.insertUser(user)); } }

测试结果如图：



即完成插入功能！

8.springMVC模块搭建
