动态地忽略事务方法
我正在编写一个与 SOAP API 对话的程序。我正在编写的程序涉及金钱，能够在运行时确定会很有用（我的理由是，如果我可以在运行时处理它，我可以轻松地将配置文件放在一起以供编译后使用）我是否想要执行处理金钱的方法。
我有一个所有 API 调用都要经过的 make request 方法，理想情况下我想要这样的东西：
...
@DealsWithMoney
public void myMethodWhichMakesAnAPIRequest() {
...
this.makeRequest(...);
}
public void makeRequest(...) {
if (!this.allowMoneyHandlingMethods) {
//Psuedo code
if (method_that_called_this_method has @DealsWithMoney annotation) {
//ignore
}
}
}
如何编写这个自定义注释？或者有更好的方法来处理这个问题吗？
I'm writing a program which talks to a SOAP API. The program I'm writing deals with money, and it would be useful to be able to determine at run time (my reasoning being that if I can deal with it at run time I can easily put together configuration files for use post-compilation) whether or not I want the methods which deal with money to be executed.
I have a make request method which all API calls go through, ideally I would like something like so:
...
@DealsWithMoney
public void myMethodWhichMakesAnAPIRequest() {
...
this.makeRequest(...);
}
public void makeRequest(...) {
if (!this.allowMoneyHandlingMethods) {
//Psuedo code
if (method_that_called_this_method has @DealsWithMoney annotation) {
//ignore
}
}
}
How can I write this custom annotation? Or is there a better method for handling this?

将为您定义注释。
获取堆栈跟踪，从中您应该能够获取调用者的
Method或Member引用，并检查您要查找的注释是否在返回的列表。
will define the annotation for you.
gets the stack track from which you should be able to get the
MethodorMemberreference of the caller and doand check to see if the annotation you are looking for is in the returned list.
