微信JsAPI(java)支付，支付完成后notify_url无法调用_course

最近做微信支付，以前也没做过微信方面的东西，所以都不懂。。 只能求助各位大神了。。 微信文档中说明，在支付成功后会根据notify_url中设置的地址通知商户支付成功的信息， 但是现在不管是将地址设置为xxx.do还是设置为授权目录下的xxx.jsp都不行。 麻烦各位做过的帮忙解答下吧。 谢谢。

微信支付notify_url回调_course

package com.tra.action; import java.io.BufferedOutputStream; import java.io.IOException; import java

java 并发基础 notify()与notifyAll() 的理解_course

Exception in thread "pool-1-thread-1" java.lang.IllegalMonitorStateException at java.lang.Object.notifyAll(Native Method) at concurrency.Chef.run(Restaurant.java:69) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624) at java.lang.Thread.run(Thread.java:748) ``` 2. 这2种调用的方法有什么区别
