spring maven項目 关于classpath的理解

1、用以下代码可以获取項目classpath的路径

ServerTimeGetTest.class.getResource("/")

ServerTimeGetTest.class.getClassLoader().getResource("")

例如:file:/D:\Users\hp\Desktop\tomcat\apache-tomcat-8.5.37\webapps\sps-sysfw-std\WEB-INF\classes

src/main/resources目录下的配置文件都会生成到该路径下

2、classpath*:和classpath:区别

3、classpath解析

classpath解析主要用到的类:PathMatchingResourcePatternResolver 类，位于包 org.springframework.core.io.support 下，该类中的 getResources 函数是逻辑的核心.

4、测试代码

ResourcePatternResolver resourceLoader = new PathMatchingResourcePatternResolver();

//classpath:applicationContextTest_*.xml

//classpath:applicationContextTest_common.xml

//classpath*:applicationContextTest_common.xml

Resource[] source = resourceLoader.getResources("classpath*:applicationContextTest_*.xml");

System.out.println("source.size: " + source.length);

for (int i =0; i < source.length; i++) {

    Resource resource = source[i];

    System.out.println(resource);

}
