- 建立maven支持的web project
2、通过maven来管理jar文件，在porm.xml中导入以下jar文件
<!-- spring-context --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>4.3.4.RELEASE</version> </dependency> <!-- spring-webmvc --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>4.3.4.RELEASE</version> </dependency> <!-- spring-jdbc --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>4.3.4.RELEASE</version> </dependency> <!-- mybatis-spring --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis-spring</artifactId> <version>1.2.2</version> </dependency> <!-- spring-tx --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-tx</artifactId> <version>4.3.4.RELEASE</version> </dependency> <!-- druid --> <dependency> <groupId>com.alibaba</groupId> <artifactId>druid</artifactId> <version>1.0.18</version> </dependency> <dependency> <groupId>aspectj</groupId> <artifactId>aspectjweaver</artifactId> <version>1.5.4</version> </dependency> <!-- mybatis --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>3.3.1</version> </dependency> <!-- log4j --> <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>1.2.17</version> </dependency> <!-- mysql-connector-java --> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.38</version> </dependency> <!-- joda-time --> <dependency> <groupId>joda-time</groupId> <artifactId>joda-time</artifactId> <version>2.9.4</version> </dependency> <!-- jackson-databind --> <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-databind</artifactId> <version>2.7.8</version> </dependency> <!-- junit --> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.11</version> </dependency>mybaits generator可以直接生成sqlmapper.xml文件、entity文件和dao层的mapper接口文件。
mybaits包下放sqlmapper.xml和configuration.xml文件。
configuration.xml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> <settings> <setting name="useGeneratedKeys" value="true"/> <setting name="useColumnLabel" value="true"/> </settings> <typeAliases> <package name="com.spring.entity"></package> </typeAliases></configuration>目录结构 
参考http://docs.spring.io/spring/docs/current/spring-framework-reference/htmlsingle/
3、配置web.xml文件
spring mvc转发servlet
<!-- 配置spring --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring/spring.xml</param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- 配置spring mvc --> <servlet> <servlet-name>spring_mvc</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring/spring_mvc.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>spring_mvc</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping>spring.xml文件
<?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.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd"> <context:annotation-config></context:annotation-config> <context:component-scan base-package="com.spring"> <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller" /> </context:component-scan> <import resource="spring_mybaits.xml"/></beans>spring mvc.xml文件
要获取静态资源必须进行设置。
<?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"> <!-- 静态资源不拦截 --> <mvc:annotation-driven></mvc:annotation-driven> <mvc:resources location="/image/" mapping="/image/**"/> <mvc:resources location="/css/" mapping="/css/**"/> <mvc:resources location="/js/" mapping="/js/**"/> <context:component-scan base-package="com.spring.controller"></context:component-scan> <!-- 在 Controller返回的 ModelAndView的基础上，加上前缀/WEB-INF/jsp/,后缀.jsp --> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/> <property name="prefix" value="/WEB-INF/jsp/"/> <property name="suffix" value=".jsp"/> </bean> <!-- 转化 json --> <bean id="stringConverter" class="org.springframework.http.converter.StringHttpMessageConverter"> <property name="supportedMediaTypes"> <list> <value>text/plain;charset=UTF-8</value> <value>text/json;charset=UTF-8</value> </list> </property> </bean> <bean id="jsonConverter" class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter"></bean> <bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter"> <property name="messageConverters"> <list> <ref bean="stringConverter" /> <ref bean="jsonConverter" /> </list> </property> </bean> </beans>spring baits.xml文件
通过spring来整合mybaits，用到了druid的数据库连接池。
<?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.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd"> <bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"> <property name="location" value="classpath:jdbc.properties"/> </bean> <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource" destroy-method="close"> <property name="driverClassName" value="${driver}" /> <property name="url" value="${url}" /> <property name="username" value="${username}" /> <property name="password" value="${password}" /> <!-- 初始化连接大小 --> <property name="initialSize" value="${initialSize}"></property> <!-- 连接池最大数量 --> <property name="maxActive" value="${maxActive}"></property> <!-- 连接池最大空闲 --> <property name="maxIdle" value="${maxIdle}"></property> <!-- 连接池最小空闲 --> <property name="minIdle" value="${minIdle}"></property> <!-- 获取连接最大等待时间 --> <property name="maxWait" value="${maxWait}"></property> <!-- 配置间隔多久才进行一次检测，检测需要关闭的空闲连接，单位是毫秒 --> <property name="timeBetweenEvictionRunsMillis" value="${timeBetweenEvictionRunsMillis}" /> <!-- 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="${minEvictableIdleTimeMillis}" /> <property name="validationQuery" value="${validationQuery}" /> <property name="testWhileIdle" value="${testWhileIdle}" /> <property name="testOnBorrow" value="${testOnBorrow}" /> <property name="testOnReturn" value="${testOnReturn}" /> <property name="maxOpenPreparedStatements" value="${maxOpenPreparedStatements}" /> <!-- 打开removeAbandoned功能 --> <property name="removeAbandoned" value="${removeAbandoned}" /> <!-- 1800秒，也就是30分钟 --> <property name="removeAbandonedTimeout" value="${removeAbandonedTimeout}" /> <!-- 关闭abanded连接时输出错误日志 --> <property name="logAbandoned" value="${logAbandoned}" /> </bean> <!-- spring和 MyBatis整合，不需要mybatis的配置映射文件 --> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <property name="dataSource" ref="dataSource" ></property> <!-- 自动扫描 mapping.xml文件 --> <property name="mapperLocations" value="classpath:mybaits/*Mapper.xml"></property> <property name="configLocation" value="classpath:mybaits/Configuration.xml"></property> </bean> <!-- DAO接口所在包名，Spring会自动查找其下的类 --> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="basePackage" value="com.spring.dao" /> <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property> </bean> <!-- (事务管理)transaction manager, use JtaTransactionManager for global tx --> <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name="dataSource" ref="dataSource" /> </bean> <!-- 事务日志 --> <bean id="logAspect" class="com.spring.aop.LogAspect"></bean> <!-- 事务管理规则 --> <tx:advice id="myAdvice" transaction-manager="transactionManager"> <tx:attributes> <tx:method name="add*" propagation="REQUIRED" rollback-for="java.lang.Exception"/> <tx:method name="delete*" propagation="REQUIRED" rollback-for="java.lang.Exception"/> <tx:method name="edit*" propagation="REQUIRED" rollback-for="java.lang.Exception"/> </tx:attributes> </tx:advice> <aop:config> <!-- 管理区域 --> <!--com.spring.service包下的任意子文件下的任意方法，第一个*是返回值--> <aop:pointcut expression="execution(* com.spring.service..*(..))" id="myCut"/> <!-- 通过myAdvice来管理myCut --> <aop:advisor advice-ref="myAdvice" pointcut-ref="myCut"/> <!--增加日志--> <aop:aspect id="logAop" ref="logAspect"> <aop:before method="before" pointcut-ref="myCut"/> <aop:after method="after" pointcut-ref="myCut"/> <aop:after-returning method="afterReturn" returning="value" pointcut-ref="myCut"/> </aop:aspect> </aop:config></beans>jdbc.properties文件
