1、导入需要用到的jar包
<dependencies> <!--Spring核心包--> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>${spring.version}</version> </dependency> <!--SpringMVC核心包--> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-web</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>${spring.version}</version> </dependency> <!--Spring-test测试--> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-test</artifactId> <version>${spring.version}</version> </dependency> <!--文件上传--> <dependency> <groupId>commons-fileupload</groupId> <artifactId>commons-fileupload</artifactId> <version>1.3.3</version> </dependency> <!--jackson--> <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-databind</artifactId> <version>2.9.8</version> </dependency> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.12</version> </dependency> <!--Servlet的包--> <dependency> <groupId>javax.servlet</groupId> <artifactId>javax.servlet-api</artifactId> <version>3.0.1</version> </dependency> <!--mybatis核心包--> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>3.4.6</version> </dependency> <!--数据库驱动包--> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.46</version> </dependency> <!--log4j日志包：用于打印详细日志（可不要）：需配合log4j.properties使用--> <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>1.2.17</version> </dependency> <!--mybatis与spring整合包是mybatis提供的(mybatis-spring-xxxx.jar)，不是spring-orm--> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis-spring</artifactId> <version>1.3.2</version> </dependency> <!--Spring的支持--> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-tx</artifactId> <version>${spring.version}</version> </dependency> <!--连接池--> <dependency> <groupId>commons-dbcp</groupId> <artifactId>commons-dbcp</artifactId> <version>1.4</version> </dependency> </dependencies>
2、数据库连接配置（jdbc.properties）
jdbc.driverClassName=com.mysql.jdbc.Driver jdbc.url=jdbc:mysql:///数据库名称?useSSL=false&useUnicode=true&characterEncoding=utf8 jdbc.username=用户名 jdbc.password=密码
3、打印日志配置（可不要：log4j.properties【名字必须为这个】）
#log4j.properties(日志文件:) log4j.rootLogger=ERROR, stdout #log4j.rootLogger=NONE log4j.logger.cn.wang=TRACE 注意：cn.wang是需要要打印日志的java文件所在的包 log4j.appender.stdout=org.apache.log4j.ConsoleAppender log4j.appender.stdout.layout=org.apache.log4j.PatternLayout log4j.appender.stdout.layout.ConversionPattern=%d %p [%c] - %m%n
4、Spring+MyBatis的集成配置（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" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd"> <!--用来整合Mybatis--> <!--事务使用：扫描的包 Service--> <context:component-scan base-package="cn.wang.service"/> <!--引用jdbc配置的属性文件--> <context:property-placeholder location="classpath:jdbc.properties"/> <!--数据源--> <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close"> <property name="driverClassName" value="${jdbc.driverClassName}" /> <property name="url" value="${jdbc.url}" /> <property name="username" value="${jdbc.username}" /> <property name="password" value="${jdbc.password}" /> </bean> <!--配置SqlSessionFactory--> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <property name="dataSource" ref="dataSource" /> <!--配置别名--> <property name="typeAliasesPackage" value="cn.wang.domain"/> <!--注册映射文件:扫描mapper目录下的所有mapper.xml文件--> <property name="mapperLocations" value="cn.wang.mapper.*Mapper.xml"/> </bean> <!--注入映射器（给单独一个mapper接口）--> <!--<bean id="userMapper" class="org.mybatis.spring.mapper.MapperFactoryBean"> <property name="mapperInterface" value="cn.wang.mapper.UserMapper" /> <property name="sqlSessionFactory" ref="sqlSessionFactory" /> </bean>--> <!--注入映射器（给全部mapper接口：自动扫描Mapper接口生成代理注入到Spring）--> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="basePackage" value="cn.wang.mapper" /> </bean> <!--事务管理--> <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name="dataSource" ref="dataSource"/> </bean> <!--以注解的形式进行事务管理--> <tx:annotation-driven transaction-manager="transactionManager"/> </beans>
5、SpringMVC配置（applicationContext-mvc.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" xmlns:mvc="http://www.springframework.org/schema/mvc" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd"> <!--扫描的包Controller--> <context:component-scan base-package="cn.wang.controller"/> <!--启用SpringMVC的注解支持--> <mvc:annotation-driven/> <!--静态资源放行--> <mvc:default-servlet-handler/> <!--视图解析器--> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/WEB-INF/views/"/> <property name="suffix" value=".jsp"/> </bean> <!--文件上传解析器--> <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"> <property name="maxUploadSize"> <value>200000000</value> </property> </bean> </beans>
6、web.xml配置
<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" version="3.1"> <!--Spring核心配置文件--> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:applicationContext.xml</param-value> </context-param> <!--SpringMVC的核心控制器--> <servlet> <servlet-name>dispatcher</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <!--SpringMVC的配置文件--> <param-name>contextConfigLocation</param-name> <param-value>classpath:applicationContext-mvc.xml</param-value> </init-param> <!--即SpringMVC跟着服务器(tomcat)的启动而启动 --> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>dispatcher</servlet-name> <!--使用杠（/）更加符合咱们的RESTful风格 --> <url-pattern>/</url-pattern> </servlet-mapping> <!--Spring启动的监听器--> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- 配置相应的过滤器:角色SpringMVC 的POST请求的乱码问题 --> <!-- 配置编码方式过滤器,注意一点:要配置在所有过滤器的前面 --> <filter> <filter-name>encodingFilter</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> </filter> <filter-mapping> <filter-name>encodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> </web-app>
7、MyBatis的映射文件（实体类名+Mapper.xml）
<?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"> <!--namespace:映射器的全限定名--> <mapper namespace="cn.wang.mapper.UserMapper"> <!--id:映射器中对应的方法名，resultType:返回的数据类型（这里使用了别名，别名在applicationContext.xml里配置）--> <select id="findAll" resultType="User"> select * from t_user </select> </mapper>
