常量字段值

CLASSPATH_ALL_URL_PREFIX

public static final String CLASSPATH_ALL_URL_PREFIX

Pseudo URL prefix for all matching resources from the class path: "classpath*:" This differs from ResourceLoader's classpath URL prefix in that it retrieves all matching resources for a given name (e.g. "/beans.xml"), for example in the root of all deployed JAR files.
