用jmeter测试SpringBoot异步controller
下面的示例是在 springboot 的 controller 中整合异步service调用的示例。
我们需要完成：
- 做一个提供测试测试数据的 controller。
- 创建一个异步的 service，远程调用上面的测试数据 controller。
- 创建一个 controller，调用多个异步 service，并等待异步调用全部完成，输出结果。
示例
1. 测试数据 controller
package com.example.demoasync; import java.util.ArrayList; import java.util.List; import org.slf4j.Logger; import org.slf4j.LoggerFactory; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; import org.springframework.web.bind.annotation.RestController; @RestController public class EmployeeDataController { private static Logger log = LoggerFactory.getLogger(EmployeeDataController.class); @RequestMapping(value = "/addresses", method = RequestMethod.GET) public List<String> getAddresses() { log.info("get addresses Start"); ArrayList<String> employeeAddresses = new ArrayList<String>(); employeeAddresses.add("addr1"); employeeAddresses.add("addr2"); employeeAddresses.add("addr3"); return employeeAddresses; } @RequestMapping(value = "/phones", method = RequestMethod.GET) public List<String> getPhoneNumbers() { log.info("get phones Start"); ArrayList<String> phoneNumberList = new ArrayList<String>(); phoneNumberList.add("100000"); phoneNumberList.add("200000"); return phoneNumberList; } @RequestMapping(value = "/names", method = RequestMethod.GET) public List<String> getEmployeeName() { log.info("get names Start"); List<String> employeeList = new ArrayList<String>(); employeeList.add("Santa"); employeeList.add("Banta"); return employeeList; } }
2. 异步 service
import java.util.List; import java.util.concurrent.CompletableFuture; import org.slf4j.Logger; import org.slf4j.LoggerFactory; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.context.annotation.Bean; import org.springframework.scheduling.annotation.Async; import org.springframework.stereotype.Service; import org.springframework.web.client.RestTemplate; @Service public class AsyncService { private static Logger log = LoggerFactory.getLogger(AsyncService.class); @Autowired private RestTemplate restTemplate; @Bean public RestTemplate restTemplate() { return new RestTemplate(); } @Async("asyncExecutor") public CompletableFuture<List<String>> getEmployeeName() throws InterruptedException { log.info("getEmployeeName starts"); List<String> employeeNameData = restTemplate.getForObject("http://localhost:8080/names", List.class); log.info("employeeNameData, {}", employeeNameData); Thread.sleep(1000L); // Intentional delay log.info("employeeNameData completed"); return CompletableFuture.completedFuture(employeeNameData); } @Async("asyncExecutor") public CompletableFuture<List<String>> getEmployeeAddress() throws InterruptedException { log.info("getEmployeeAddress starts"); List<String> employeeAddressData = restTemplate.getForObject("http://localhost:8080/addresses", List.class); log.info("employeeAddressData, {}", employeeAddressData); Thread.sleep(1000L); // Intentional delay log.info("employeeAddressData completed"); return CompletableFuture.completedFuture(employeeAddressData); } @Async("asyncExecutor") public CompletableFuture<List<String>> getEmployeePhone() throws InterruptedException { log.info("getEmployeePhone starts"); List<String> employeePhoneData = restTemplate.getForObject("http://localhost:8080/phones", List.class); log.info("employeePhoneData, {}", employeePhoneData); Thread.sleep(1000L); // Intentional delay log.info("employeePhoneData completed"); return CompletableFuture.completedFuture(employeePhoneData); } }
或者：
@Async public CompletableFuture<List<RouteSelfCureDetailDTO>> getRouteSelfCureDetailList() { List<RouteSelfCureDetailDTO> list = routeMapper.getSelfCureDetailList(); if (CollectionUtils.isEmpty(list)) { logger.info("There is no data, please adding first."); return CompletableFuture.completedFuture(new ArrayList<>()); } list.stream().forEach(t -> { if (StringUtils.isEmpty(t.getSelfCureStatus())) { t.setSelfCureStatus(Constants.ROUTE_UP_STATUS); } }); return CompletableFuture.completedFuture(list); }
3. controller
package com.example.demoasync; import java.util.List; import java.util.concurrent.CompletableFuture; import java.util.concurrent.ExecutionException; import org.slf4j.Logger; import org.slf4j.LoggerFactory; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; import org.springframework.web.bind.annotation.RestController; @RestController public class AsyncController { private static Logger log = LoggerFactory.getLogger(AsyncController.class); @Autowired private AsyncService service; @RequestMapping(value = "/testAsynch", method = RequestMethod.GET) public void testAsynch() throws InterruptedException, ExecutionException { log.info("testAsynch Start"); CompletableFuture<List<String>> employeeAddress = service.getEmployeeAddress(); CompletableFuture<List<String>> employeeName = service.getEmployeeName(); CompletableFuture<List<String>> employeePhone = service.getEmployeePhone(); // 等待每个异步调用都完成 CompletableFuture.allOf(employeeAddress, employeeName, employeePhone).join(); log.info("EmployeeAddress--> " + employeeAddress.get()); log.info("EmployeeName--> " + employeeName.get()); log.info("EmployeePhone--> " + employeePhone.get()); } }
或者：
@RequestMapping(value = "/get_route_selfcure_list", method = RequestMethod.GET) public CompletableFuture<RetMsg> getRouteSelfCureDetailList() { if (logger.isDebugEnabled()) { logger.debug("getRouteSelfCureDetailList method begins"); } CompletableFuture<List<RouteSelfCureDetailDTO>> future = detailApi.getRouteSelfCureDetailList(); return future.thenApplyAsync(routeSelfCureDetailDTOS -> { if (CollectionUtils.isEmpty(routeSelfCureDetailDTOS)) { return new FailMsg(SelfCureExecuting.RetMsg.ROUTE_SELFCURE_DETAIL_ERROR_CODE, SelfCureExecuting.RetMsg.ROUTE_SELFCURE_DETAIL_ERROR_MSG); } return new SucMsg(routeSelfCureDetailDTOS); }); }
4.在启动类上添加@EnableAsync注解：
@EnableAsync public class Application { ....... }
5.在过滤器上添加异步支持：
@WebFilter(urlPatterns = "/*", filterName = "corsFilter", asyncSupported = true) public class CorsFilter implements Filter { ........ }
6.最后把内置的Tomcat替换成jetty：
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> <exclusions> <exclusion> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-tomcat</artifactId> </exclusion> </exclusions> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-jetty</artifactId> </dependency>
7.设置jetty启动参数：
server.jetty.connection-idle-timeout=60000
server.jetty.threads.max-queue-capacity=2000
server.jetty.threads.max=4500
server.jetty.threads.min=4000
使用jmeter测试，需要添加cookie
使用Jmeter性能测试遇到的问题：java.net.SocketException: Connection reset by peer: socket write error at java.net.SocketOutputStream.socketWrite0(Native Method) at java.net.SocketOutputStream.socketWrite(Unknown Source) at java.net.SocketOutputStream.write(Unknown Source) at sun.security.ssl.OutputRecord.writeBuffer(Unknown Source) at sun.security.ssl.OutputRecord.write(Unknown Source) at
解决方法：
Make sure that your HTTP Requests "Implementation" is HTTPClient4
Add the following lines to user.properties file (located in /bin folder of your JMeter home)
httpclient4.retrycount=1
hc.parameters.file=hc.parameters
In the hc.parameters file (same location - JMeter's /bin folder) uncomment the next line:
http.connection.stalecheck$Boolean=true
