标签：必须 srping 视图解析器 class int conf 映射 前端 service
1.jar包
Spring的jar包；Mybatis的jar包；Mybatis与Spring整合包；数据库连接包；第三方连接池包。
2.需要配置的文件
SqlMapConfig.xml：Mybatis核心配置文件（主要交给Spring管理，并不需要什么配置，但必须存在）
db.properties：数据库连接配置，主要配置用户密码
applicationContext*.xml：Spring的核心配置，配置数据源、连接池、mapper扫描包位置、事务、service扫描。
（*表示可以将事务单独成一个配置，例如：applicationContext-dao.xml）
springmvc.xml：配置扫描注解包（可包括Spring配置中的service扫描包）、注解驱动（处理器的适配器和映射器配置）、视图解析器、自定义转换器
log4j.properties：日志配置
web.xml：前端配置
3.SqlMapConfig.xml
1 <?xml version="1.0" encoding="UTF-8" ?> 2 <!DOCTYPE configuration 3 PUBLIC "-//mybatis.org//DTD Config 3.0//EN" 4 "http://mybatis.org/dtd/mybatis-3-config.dtd"> 5 <configuration> 6 <!-- 逆向工程生成的不需要别名 --> 7 </configuration>
4.db.properties
5.applicationContext*.xml
applicationContext-dao.xml：
1 <?xml version="1.0" encoding="UTF-8"?> 2 <beans xmlns="http://www.springframework.org/schema/beans" 3 xmlns:context="http://www.springframework.org/schema/context" 4 xmlns:p="http://www.springframework.org/schema/p" 5 xmlns:aop="http://www.springframework.org/schema/aop" 6 xmlns:tx="http://www.springframework.org/schema/tx" 7 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 8 xsi:schemaLocation=" 9 http://www.springframework.org/schema/beans 10 http://www.springframework.org/schema/beans/spring-beans-4.0.xsd 11 http://www.springframework.org/schema/context 12 http://www.springframework.org/schema/context/spring-context-4.0.xsd 13 http://www.springframework.org/schema/aop 14 http://www.springframework.org/schema/aop/spring-aop-4.0.xsd 15 http://www.springframework.org/schema/tx 16 http://www.springframework.org/schema/tx/spring-tx-4.0.xsd 17 http://www.springframework.org/schema/util 18 http://www.springframework.org/schema/util/spring-util-4.0.xsd"> 19 20 <!-- 加载配置文件 --> 21 <context:property-placeholder location="classpath:db.properties" /> 22 23 <!-- 数据库连接池 --> 24 <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" 25 destroy-method="close"> 26 <property name="driverClassName" value="${jdbc.driver}" /> 27 <property name="url" value="${jdbc.url}" /> 28 <property name="username" value="${jdbc.username}" /> 29 <property name="password" value="${jdbc.password}" /> 30 <property name="maxActive" value="10" /> 31 <property name="maxIdle" value="5" /> 32 </bean> 33 34 <!-- 配置SqlSessionFactory --> 35 <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> 36 <!-- 配置mybatis核心配置文件 --> 37 <property name="configLocation" value="classpath:mybatis/SqlMapConfig.xml" /> 38 <!-- 配置数据源 --> 39 <property name="dataSource" ref="dataSource" /> 40 </bean> 41 42 43 <!-- 配置mapper扫描设置 --> 44 <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> 45 <!-- 只需要设置基本包路径 --> 46 <property name="basePackage" value="com.springmvc.dao"></property> 47 </bean> 48 49 </beans>
classpath指定是文件路径。建议将约束都导入，方便配置。
applicationContext-trans.xml：
1 <?xml version="1.0" encoding="UTF-8"?> 2 <beans xmlns="http://www.springframework.org/schema/beans" 3 xmlns:context="http://www.springframework.org/schema/context" 4 xmlns:p="http://www.springframework.org/schema/p" 5 xmlns:aop="http://www.springframework.org/schema/aop" 6 xmlns:tx="http://www.springframework.org/schema/tx" 7 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 8 xsi:schemaLocation=" 9 http://www.springframework.org/schema/beans 10 http://www.springframework.org/schema/beans/spring-beans-4.0.xsd 11 http://www.springframework.org/schema/context 12 http://www.springframework.org/schema/context/spring-context-4.0.xsd 13 http://www.springframework.org/schema/aop 14 http://www.springframework.org/schema/aop/spring-aop-4.0.xsd 15 http://www.springframework.org/schema/tx 16 http://www.springframework.org/schema/tx/spring-tx-4.0.xsd 17 http://www.springframework.org/schema/util 18 http://www.springframework.org/schema/util/spring-util-4.0.xsd"> 19 20 <!-- 事务管理器 --> 21 <bean id="transactionManager" 22 class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> 23 <!-- 数据源 --> 24 <property name="dataSource" ref="dataSource" /> 25 </bean> 26 27 <!-- 通知 --> 28 <tx:advice id="txAdvice" transaction-manager="transactionManager"> 29 <tx:attributes> 30 <!-- 传播行为 --> 31 <tx:method name="save*" propagation="REQUIRED" /> 32 <tx:method name="insert*" propagation="REQUIRED" /> 33 <tx:method name="delete*" propagation="REQUIRED" /> 34 <tx:method name="update*" propagation="REQUIRED" /> 35 <tx:method name="find*" propagation="SUPPORTS" read-only="true" /> 36 <tx:method name="get*" propagation="SUPPORTS" read-only="true" /> 37 <tx:method name="query*" propagation="SUPPORTS" read-only="true" /> 38 </tx:attributes> 39 </tx:advice> 40 41 <!-- 切面 --> 42 <aop:config> 43 <aop:advisor advice-ref="txAdvice" 44 pointcut="execution(* cn.itcast.ssm.service.*.*(..))" /> 45 </aop:config> 46 47 < 48 49 50 </beans>
上面演示的是采用配置式，下面采用注解式：
1 <bean id="transactionManager" class=""org.springframework.jdbc.datasource.DataSourceTransactionManager> 2 <property name="dataSource" ref="dataSource"></property> 3 </bean> 4 <tx:annotation-driven transaction-manager="transactionManager"/>
