怎么进行java并发模拟

怎么进行java并发模拟，很多新手对此不是很清楚，为了帮助大家解决这个难题，下面小编将为大家详细讲解，有这方面需求的人可以来学习下，希望你能有所收获。

在project-1中新建controller，TestController.java内容如下：

@RestController@Slf4jpublic class TestController {    @GetMapping("/test")    public String test() {        return "test";    }}

需要依赖Slf4j包，需要在pom.xml文件中添加依赖：

                    org.projectlombok            lombok            1.18.6        

POSTMAN工具测试

在postman工具中新建collection：

并将测试url添加到这个collection中，点击run，然后配置：

Apache bench工具

ab -n 1000 -c 50 http://localhost:8080/test

输出结果如下：

-n 1000表示本次测试的总数为100个

-c 50表示本次请求的并发数是50
