我对此很好奇。
这个“classpath*”声明在哪里？
Follow 通常在 web.xml 中描述。
<servlet>
<servlet-name>action</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>
classpath*:egovframework/springmvc/context-*.xml
</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
我认为这个框架首先读取了 web.xml。但是它怎么知道这个关键字“classpath*:”呢？
提前感谢您的回答:D

我相信spring docs很好地描述类路径资源:
ClassPathResource
This class represents a resource which should be obtained from the classpath. This uses either the thread context class loader, a given class loader, or a given class for loading resources.
This Resource implementation supports resolution as java.io.File if the class path resource resides in the file system, but not for classpath resources which reside in a jar and have not been expanded (by the servlet engine, or whatever the environment is) to the filesystem. To address this the various Resource implementations always support resolution as a java.net.URL.
A ClassPathResource is created by Java code explicitly using the ClassPathResource constructor, but will often be created implicitly when you call an API method which takes a String argument which is meant to represent a path. For the latter case, a JavaBeans PropertyEditor will recognize the special prefix classpath:on the string path, and create a ClassPathResource in that case
关于java - "classpath*"在 Spring MVC 项目中声明在哪里？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/25598077/
