eclipse工具 maven 整合ssm（三）：SSM配置

eclipse工具 maven 整合ssm（三）：SSM配置

在maven项目中，SSM的配置文件和不用maven工具时是一样的，配置文件放在src/main/resources文件夹下

1.spring配置文件applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?>

</bean>

<!-- 5.配置事务管理器 -->
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">

<configuration>

<!-- 映射文件（定义SQL语句的映射文件） -->
<!-- 由spring接管，在applicationContext.xml中的4.1 -->
