创建一个Spring+SpringMVC+MyBatis+MySql+Maven项目需要注意的地方

1.pom.xml文件是Maven导入jar包的配置地方

<dependency><groupId>org.slf4j</groupId><artifactId>slf4j-log4j12</artifactId><version>1.7.5</version></dependency>

2.在spring-mvcxml与spring.xml文件中配置注解

<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.xsdhttp://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd"xmlns:tx="http://www.springframework.org/schema/tx">

3.在spring.xml文件中配置引入属性文件config.properties和自动注入

<!-- 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="com.project.service" />

4.在spring-mvc.xml中配置自动扫描类使其认为是mvc的控制层（Action）

<mvc:annotation-driven /><!-- 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="com.project.action" /><aop:aspectj-autoproxy />

5.在mybatis.xml文件中配置

<settings><!-- 返回空值，需要mybatis3.2以上版本 --><setting name="callSettersOnNulls" value="true" /><setting name="logPrefix" value="dao." /></settings><typeAliases><!-- 给实体Bean一个别名 --><typeAlias type="com.project.model.TBeds" alias="TBeds" /><typeAlias type="com.project.model.TCampus" alias="TCampus" /></typeAliases>

6.在spring-mybatis.xml文件中配置

<!-- 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" /><property name="configLocation" value="classpath:mybatis.xml" /><!-- 自动扫描entity目录, 省掉Configuration.xml里的手工配置 --><property name="mapperLocations" value="classpath:com/project/mapping/*.xml" /></bean><bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"><property name="basePackage" value="geese.apartment.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="import*" 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(* com.project.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>geese.apartment.service.*</value></list></property></bean><aop:config><aop:advisor advice-ref="druid-stat-interceptor" pointcut-ref="druid-stat-pointcut" /></aop:config>

7.在Sconfig.properties文件中配置

validationQuery=SELECT 1jdbc_url=jdbc:mysql://localhost:3306/dbbase?useUnicode=true&characterEncoding=UTF-8&zeroDateTimeBehavior=convertToNulljdbc_username=rootjdbc_password=roothibernate.hbm2ddl.auto=updatehibernate.show_sql=falsehibernate.format_sql=truesessionInfoName=sessionInfouploadFieldName=filedatauploadFileMaxSize=20971520uploadFileExts=txt,rar,zip,doc,docx,xls,xlsx,jpg,jpeg,gif,png,swf,wmv,avi,wma,mp3,miduploadDirectory=attached
