SpringMVC+Mybatis+Maven框架配置文件介绍

主要为几个配置文件：spring.xml，spring-bean.xml，spring-mvc.xml，mybatis-config.xml，generatorConfig.xml

spring.xml如下所示:

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"xmlns:tx="http://www.springframework.org/schema/tx" xmlns:aop="http://www.springframework.org/schema/aop"xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p"xmlns:mvc="http://www.springframework.org/schema/mvc" 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        http://www.springframework.org/schema/mvc       http://www.springframework.org/schema/mvc/spring-mvc-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"><import resource="spring-bean.xml" /><!-- 引入数据库属性文件 --><context:property-placeholder location="classpath:properties/db.properties" /><!-- 配置datasource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><!-- 配置mybatis --><bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"><property name="dataSource" ref="dataSource" /><property name="configLocation" value="classpath:mybatis/mybatis-config.xml" /></bean><!-- 配置事物管理 --><bean id="transactionManager"class="org.springframework.jdbc.datasource.DataSourceTransactionManager"><property name="dataSource" ref="dataSource" /></bean><tx:annotation-driven transaction-manager="transactionManager" /><!-- 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>com.fafa.service.*</value> --><!-- </list> --><!-- </property> --><!-- </bean> --><!-- <aop:config> --><!-- <aop:advisor advice-ref="druid-stat-interceptor" --><!-- pointcut-ref="druid-stat-pointcut" /> --><!-- </aop:config> --></beans>

根据配置，事物管理只需要在service层的方法前加上注解

@Transactional(propagation = Propagation.SUPPORTS, rollbackFor = { RuntimeException.class, Exception.class })

即可利用spring的事物管理进行完整性事物控制，包括回滚、重做等。

spring-baen.xml文件如下：

<?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/beanshttp://www.springframework.org/schema/beans/spring-beans-3.0.xsdhttp://www.springframework.org/schema/contexthttp://www.springframework.org/schema/context/spring-context-3.0.xsd"><!-- 自动扫描（自动注入） --><context:component-scan base-package="com.fafa.service" /><!-- 扫描mapper接口，自动生成代理类 --><bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"><property name="basePackage" value="com.xxxx.mapper" /><property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" /></bean></beans>

spring-mvc的文件如下：

mybatis-config.xml文件如下：

generatorConfig.xml（暂未使用）文件如下：
