项目思路整理
主要就是几个配置文件: web.xml 2.spring-mvc.xml 3.spring-mybatis.xml
1.web.xml :加载spring-mybatis.xml配置文件, 加载spring配置文件,监听,以及配置文件spring-mvc.xml的位置, 编码过滤,log4j配置文件,监听
2.spring-mvc.xml: 注解驱动 ,视图解析器
3.spring-mybatis.xml
3.1注解驱动,扫描到service层;
3.2 PropertyPlaceholderConfigurer 引入jdbc.properties 配置文件;
3.3 BasicDataSource 加载数据库驱动,url,用户名,密码 ;
3.4 SqlSessionFactoryBean,用来加载数据源以及mapping/*.xml
3.5 MapperScannerConfigurer 用来扫描Dao
3.6 DataSourceTransactionManager 事物管理
<!--==12.1注解驱动 自动扫描该包,使SpringMVC认为包下用了@controller注解的类是控制器 -->
<context:component-scan base-package="com.eaju" />
<!-2.2 定时器配置
<bean id="UnifiedOrderServiceImpl" class="com.eaju.service.impl.UnifiedOrderServiceImpl"></bean>
<task:scheduled-tasks>
<task:scheduled ref="UnifiedOrderServiceImpl" method="findAllOrder" cron="*/8 * * * * ? "></task:scheduled>
<!-- <task:scheduled ref="UnifiedOrderServiceImpl" method="findAllOrder" cron="0 0/1 * * * ?"></task:scheduled> -->
</task:scheduled-tasks>
<!--2.3 视图解析器 =============定义跳转的文件的前后缀 ,视图模式配置 -->
<bean
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<!-- 这里的配置我的理解是自动给后面action的方法return的字符串加上前缀和后缀,变成一个 可用的url地址 -->
<property name="prefix" value="/WEB-INF/view/" />
<property name="suffix" value=".jsp" />
</bean>
