怎么進(jìn)行java并發(fā)模擬,很多新手對(duì)此不是很清楚,為了幫助大家解決這個(gè)難題,下面小編將為大家詳細(xì)講解,有這方面需求的人可以來學(xué)習(xí)下,希望你能有所收獲。
在project-1中新建controller,TestController.java內(nèi)容如下:
@RestController @Slf4j public class TestController { @GetMapping("/test") public String test() { return "test"; } }
需要依賴Slf4j包,需要在pom.xml文件中添加依賴:
<dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> <version>1.18.6</version> </dependency>
在postman工具中新建collection:
并將測試url添加到這個(gè)collection中,點(diǎn)擊run,然后配置:
