===============================================================================================
1.
<url-pattern>写成/和/*的区别
/ 会匹配到/springmvc这样的路径型url,不会匹配到模式为*.jsp这样的后缀型url。
/* 会匹配所有的url:路径型的和后缀型的url(包括/springmvc,.jsp,.js和*.html等)。
1、src不是classpath, WEB-INF/classes,lib才是classpath,WEB-INF/ 是资源目录, 客户端不能直接访问。
2、WEB-INF/classes目录存放src目录Java文件编译之后的class文件,xml、properties等资源配置文件,这是一个定位资源的入口。
3、引用classpath路径下的文件,只需在文件名前加classpath:
如: 项目的 /src/main/resources 下
<!-- spring的属性加载器,加载properties文件中的属性 -->
<bean id="rdPropertyConfigurer" class="com.heyin.zkgj.common.property.PropertyCtx">
<property name="locations">
<list>
<value>classpath:/db/jdbc.properties</value>
<value>classpath:/spring/redis.properties</value>
<value>classpath:/spring/rabbit.properties</value>
</list>
</property>
<property name="fileEncoding" value="utf-8"/>
</bean>
4、lib和classes同属classpath,两者的访问优先级为: lib>classes。
5、classpath 和 classpath* 区别:
classpath:只会到你的class路径中查找找文件;
classpath*:不仅包含class路径,还包括jar文件中(class路径)进行查找。de>
