并发测试

[ghost]

可以使用testng进行并发测试，发现错误

@Test(threadPoolSize = 5001, invocationCount = 5002, timeOut = 1000000)
    public void testExecute() {
        RestTemplate template = new RestTemplate();

        HttpHeaders headers = new HttpHeaders();
        List<String> cookies = new ArrayList<>();
        cookies.add("userPhone=" + "1737467" + Phone++);
        headers.put(HttpHeaders.COOKIE, cookies);
        HttpEntity request = new HttpEntity(null, headers);

        long start = System.currentTimeMillis();
        String s = template.postForObject("http://localhost:8080/seckill/1000/bf204e2683e7452aa7db1a50b5713bae/execution", request, String.class);
        long end = System.currentTimeMillis();

        log.info("{}|{}ms ,res|{}",Thread.currentThread().getId(),(end - start),s);
    }

org.springframework.transaction.CannotCreateTransactionException: Could not open JDBC Connection for transaction; nested exception is java.sql.SQLException: An attempt by a client to checkout a Connection has timed out.
