web.xml中的classpath是啥
在web.xml中一个很面熟的字:classpath,它到底是个啥?
<servlet>
<servlet-name>dispatcherServlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>encoding</param-name>
<param-value>UTF-8</param-value>
</init-param>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:resource/spring-mvc.xml</param-value>
</init-param>
<load-on-startup>2</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>dispatcherServlet</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
首先
classpath是指 WEB-INF文件夹下的classes目录
其次据说
classpath:只会到你指定的class路径中查找文件;
classpath*:不仅包含class路径,还包括jar文件中(class路径)进行查找.
