How to call method multiple times in the same time
问题
我需要编写一些测试，这些测试将同时多次调用我的方法，使用MvcMock或其他什么东西是否可能？
我想要实现与我在bash中使用curl＆curl＆curl（异步运行多个curl请求）所实现的相同结果 - 我的方法会抛出乐观锁定异常，因为每个请求都会修改同一实体，但是我所有的测试都是通过的。
我知道解决方案（使用PESSIMISTIC进行锁定），它也运行得很好，但是我不知道如何对其进行测试。
英文:
I need to write some test which will call my method multiple times in the same time, is it possible using MvcMock or something?
I want to achieve the same result as I achieved using curl & curl & curl in bash ( run multiple curl requests asynchronously ) - my method throws Optimistic locking exception because each request modify the same entity, but all my tests are green.
I know the solution ( locking with PESSIMISTIC ) and it works fine, but I have no idea how to test it.

有什么东西会阻止使用基本的Java多线程吗？
类似这样的：
ExecutorService EXEC = Executors.newCachedThreadPool();
List<Callable<String>> tasks = new ArrayList<>();
Callable<String> c = () -> {
yourMethodCall();
return "";
};
tasks.add(c);
tasks.add(c);
tasks.add(c);
List<Future<String>> results = EXEC.invokeAll(tasks);
英文:
Is there anything that blocks using basic Java multi threading?
Something like
ExecutorService EXEC = Executors.newCachedThreadPool();
List<Callable<String>> tasks = new ArrayList<>();
Callable<String> c = () -> {
System.out.println("Hello");
return "";
};
tasks.add(c);
tasks.add(c);
tasks.add(c);
List<Future<String>> results = EXEC.invokeAll(tasks);
(replace Sys out with call of your method)
