请教一下关于java :load(Thread.currentThread())？

Question

java :load(Thread.currentThread().getContextClassLoader().getResourceAsStream("db.properties"))

Answer 1

getResource("") 返回的当然是null了
获取classpath的值使用
System.getProperty（“java.class.path”）；

Answer 2

你可以尝试下面这种方式: 　不知道是不是你想要的.　全部放入系统加载器里面.
ClassLoader classLoader=ClassLoader.getSystemClassLoader();
Thread thread0=new Thread();
thread0.currentThread().setContextClassLoader(classLoader);
Thread thread1=new Thread();
thread1.currentThread().setContextClassLoader(classLoader);
Thread thread2=new Thread();
thread2.currentThread().setContextClassLoader(classLoader);

System.out.println(thread0.getContextClassLoader());
System.out.println(thread1.getContextClassLoader());
System.out.println(thread2.getContextClassLoader());
