修改pom.xml文件，引入jar包
<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>com.demo.webdemo</groupId> <artifactId>webdemo</artifactId> <packaging>war</packaging> <version>0.0.1-SNAPSHOT</version> <name>webdemo Maven Webapp</name> <url>http://maven.apache.org</url> <dependencies> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-test</artifactId> <version>3.1.2.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>3.1.2.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>3.1.2.RELEASE</version> </dependency> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>3.1.1</version> </dependency> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis-spring</artifactId> <version>1.1.1</version> </dependency> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.21</version> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>javax.servlet-api</artifactId> <version>3.0.1</version> <!-- 只在编译时、测试时运行 --> <scope>provided</scope> </dependency> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.10</version> <scope>test</scope> </dependency> <dependency> <groupId>com.alibaba</groupId> <artifactId>druid</artifactId> <version>0.2.9</version> </dependency> <dependency> <groupId>org.aspectj</groupId> <artifactId>aspectjweaver</artifactId> <version>1.7.1</version> </dependency> <dependency> <groupId>org.codehaus.jackson</groupId> <artifactId>jackson-mapper-asl</artifactId> <version>1.9.11</version> </dependency> <dependency> <groupId>commons-fileupload</groupId> <artifactId>commons-fileupload</artifactId> <version>1.2.2</version> </dependency> <dependency> <groupId>com.alibaba</groupId> <artifactId>fastjson</artifactId> <version>1.1.26</version> </dependency> </dependencies> <build> <finalName>webdemo</finalName> <plugins> <plugin> <!-- <groupId>org.mortbay.jetty</groupId> <artifactId>jetty-maven-plugin</artifactId> <version>8.1.16.v20140903</version> --> <groupId>org.apache.tomcat.maven</groupId> <artifactId>tomcat7-maven-plugin</artifactId> <version>2.2</version> <executions> <execution> <phase>package</phase> <goals> <goal>run</goal> </goals> </execution> </executions> </plugin> </plugins> </build> </project>
修改完保存该文件是会去自动下载spring、mybatis、json、jdbc等相关jar包，需要保持联网状态。
2在src/main/resources文件夹下面新建config.properties文件，内容如下
#hibernate.dialect=org.hibernate.dialect.OracleDialect #driverClassName=oracle.jdbc.driver.OracleDriver #validationQuery=SELECT 1 FROM DUAL #jdbc_url=jdbc:oracle:thin:@localhost:1521:orcl #jdbc_username=scott #jdbc_password=tiger hibernate.dialect=org.hibernate.dialect.MySQLDialect driverClassName=com.mysql.jdbc.Driver validationQuery=SELECT 1 jdbc_url=jdbc:mysql://localhost:3306/ssm?useUnicode=true&characterEncoding=UTF-8&zeroDateTimeBehavior=convertToNull jdbc_username=root jdbc_password=root #hibernate.dialect=org.hibernate.dialect.SQLServerDialect #driverClassName=net.sourceforge.jtds.jdbc.Driver #validationQuery=SELECT 1 #jdbc_url=jdbc:jtds:sqlserver://127.0.0.1:1433/ssm #jdbc_username=sa #jdbc_password=123456 #hibernate.dialect=org.hibernate.dialect.DerbyDialect #driverClassName=org.apache.derby.jdbc.EmbeddedDriver #validationQuery=SELECT 1 #jdbc_url=jdbc:derby:sy;create=true #jdbc_username=snake #jdbc_password=snake #jndiName=java:comp/env/dataSourceName hibernate.hbm2ddl.auto=update hibernate.show_sql=false hibernate.format_sql=true sessionInfoName=sessionInfo uploadFieldName=filedata uploadFileMaxSize=20971520 uploadFileExts=txt,rar,zip,doc,docx,xls,xlsx,jpg,jpeg,gif,png,swf,wmv,avi,wma,mp3,mid uploadDirectory=attached
该文件配置了，连接数据库的地址、用户名、密码等信息。
（3）在src/main/resources文件夹下面新建spring.xml文件，内容如下
<?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-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd "> <!-- 引入属性文件 --> <context:property-placeholder location="classpath:config.properties" /> <!-- 自动扫描(自动注入) --> <context:component-scan base-package="snake.service" /> </beans>
spring配置，引入数据库相关的配置文件和自动扫描并注入wqh.service包下面的添加注解的类。
4在src/main/resources文件夹下面新建spring-mybatis.xml文件，内容如下
<?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:tx="http://www.springframework.org/schema/tx" xmlns:aop="http://www.springframework.org/schema/aop" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd "> <!-- JNDI方式配置数据源 --> <!-- <bean id="dataSource" class="org.springframework.jndi.JndiObjectFactoryBean"> <property name="jndiName" value="${jndiName}"></property> </bean> --> <!-- 配置数据源 --> <bean name="dataSource" class="com.alibaba.druid.pool.DruidDataSource" init-method="init" destroy-method="close"> <property name="url" value="${jdbc_url}" /> <property name="username" value="${jdbc_username}" /> <property name="password" value="${jdbc_password}" /> <!-- 初始化连接大小 --> <property name="initialSize" value="0" /> <!-- 连接池最大使用连接数量 --> <property name="maxActive" value="20" /> <!-- 连接池最大空闲 --> <property name="maxIdle" value="20" /> <!-- 连接池最小空闲 --> <property name="minIdle" value="0" /> <!-- 获取连接最大等待时间 --> <property name="maxWait" value="60000" /> <!-- <property name="poolPreparedStatements" value="true" /> <property name="maxPoolPreparedStatementPerConnectionSize" value="33" /> --> <property name="validationQuery" value="${validationQuery}" /> <property name="testOnBorrow" value="false" /> <property name="testOnReturn" value="false" /> <property name="testWhileIdle" value="true" /> <!-- 配置间隔多久才进行一次检测，检测需要关闭的空闲连接，单位是毫秒 --> <property name="timeBetweenEvictionRunsMillis" value="60000" /> <!-- 配置一个连接在池中最小生存的时间，单位是毫秒 --> <property name="minEvictableIdleTimeMillis" value="25200000" /> <!-- 打开removeAbandoned功能 --> <property name="removeAbandoned" value="true" /> <!-- 1800秒，也就是30分钟 --> <property name="removeAbandonedTimeout" value="1800" /> <!-- 关闭abanded连接时输出错误日志 --> <property name="logAbandoned" value="true" /> <!-- 监控数据库 --> <!-- <property name="filters" value="stat" /> --> <property name="filters" value="mergeStat" /> </bean> <!-- myBatis文件 --> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <property name="dataSource" ref="dataSource" /> <!-- 自动扫描entity目录, 省掉Configuration.xml里的手工配置 --> <property name="mapperLocations" value="classpath:snake/mapping/*.xml" /> </bean> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="basePackage" value="snake.dao" /> <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" /> </bean> <!-- 配置事务管理器 --> <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name="dataSource" ref="dataSource" /> </bean> <!-- 注解方式配置事物 --> <!-- <tx:annotation-driven transaction-manager="transactionManager" /> --> <!-- 拦截器方式配置事物 --> <tx:advice id="transactionAdvice" transaction-manager="transactionManager"> <tx:attributes> <tx:method name="add*" propagation="REQUIRED" /> <tx:method name="append*" propagation="REQUIRED" /> <tx:method name="insert*" propagation="REQUIRED" /> <tx:method name="save*" propagation="REQUIRED" /> <tx:method name="update*" propagation="REQUIRED" /> <tx:method name="modify*" propagation="REQUIRED" /> <tx:method name="edit*" propagation="REQUIRED" /> <tx:method name="delete*" propagation="REQUIRED" /> <tx:method name="remove*" propagation="REQUIRED" /> <tx:method name="repair" propagation="REQUIRED" /> <tx:method name="delAndRepair" propagation="REQUIRED" /> <tx:method name="get*" propagation="SUPPORTS" /> <tx:method name="find*" propagation="SUPPORTS" /> <tx:method name="load*" propagation="SUPPORTS" /> <tx:method name="search*" propagation="SUPPORTS" /> <tx:method name="datagrid*" propagation="SUPPORTS" /> <tx:method name="*" propagation="SUPPORTS" /> </tx:attributes> </tx:advice> <aop:config> <aop:pointcut id="transactionPointcut" expression="execution(* snake.service..*Impl.*(..))" /> <aop:advisor pointcut-ref="transactionPointcut" advice-ref="transactionAdvice" /> </aop:config> <!-- 配置druid监控spring jdbc --> <bean id="druid-stat-interceptor" class="com.alibaba.druid.support.spring.stat.DruidStatInterceptor"> </bean> <bean id="druid-stat-pointcut" class="org.springframework.aop.support.JdkRegexpMethodPointcut" scope="prototype"> <property name="patterns"> <list> <value>wqh.service.*</value> </list> </property> </bean> <aop:config> <aop:advisor advice-ref="druid-stat-interceptor" pointcut-ref="druid-stat-pointcut" /> </aop:config> </beans>
该文件的相关配置：配置了数据源的bean，即使用阿里巴巴开发的DruidDataSource数据源，配置了一个名叫dataSource的bean；配置myBatis的SqlSessionFactoryBean的bean，为其指明dataSource属性值为上面配的名叫dataSource的bean，mapperLocations属性值为Mapper.xml文件的路径；
配置mybatis的MapperScannerConfigurer类的相关属性值，basePackage属性代表Mapper.xml的namespace所指的Java接口的文件路径，sqlSessionFactoryBeanName属性代表了该MapperScannerConfigurer使用哪个SqlSessionFactoryBean；剩下的配置就是使用切面式的方式配置了事务管理。
5在src/main/resources文件夹下面新建spring-mvc.xml文件，内容如下
<?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-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd"> <!-- 自动扫描controller包下的所有类，使其认为spring mvc的控制器 --> <context:component-scan base-package="wqh.controller" /> <!-- 避免IE执行AJAX时,返回JSON出现下载文件 --> <bean id="mappingJacksonHttpMessageConverter" class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter"> <property name="supportedMediaTypes"> <list> <value>text/html;charset=UTF-8</value> </list> </property> </bean> <!-- 启动Spring MVC的注解功能，完成请求和注解POJO的映射 --> <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"> <property name="messageConverters"> <list> <ref bean="mappingJacksonHttpMessageConverter" /><!-- json转换器 --> </list> </property> </bean> <!-- 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" p:prefix="/" p:suffix=".jsp" /> <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"> <property name="defaultEncoding"> <value>UTF-8</value> </property> <property name="maxUploadSize"> <value>32505856</value><!-- 上传文件大小限制为31M，31*1024*1024 --> </property> <property name="maxInMemorySize"> <value>4096</value> </property> </bean> </beans>
6在src\main\webapp\WEB-INF\web.xml文件，内容如下
<?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_3_0.xsd" id="WebApp_ID" version="3.0"> <display-name>mybatis</display-name> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring.xml,classpath:spring-mybatis.xml</param-value> </context-param> <filter> <description>字符集过滤器</description> <filter-name>encodingFilter</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> <init-param> <description>字符集编码</description> <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> <listener> <description>spring监听器</description> <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> <!-- spring mvc servlet --> <servlet> <description>spring mvc servlet</description> <servlet-name>springMvc</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <description>spring mvc 配置文件</description> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring-mvc.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>springMvc</servlet-name> <url-pattern>*.do</url-pattern> </servlet-mapping> <welcome-file-list> <welcome-file>/index.jsp</welcome-file> </welcome-file-list> <!-- 配置session超时时间，单位分钟 --> <session-config> <session-timeout>15</session-timeout> </session-config> </web-app>
配置文件完成
