【发布时间】：2021-05-17 05:06:19

【问题描述】：

我正在尝试集成 Gatling 以执行自动化负载测试。但我得到了不同的错误。我需要有关此主题的帮助。

我正在使用JDK-11 版本

我的Controller类如下

import java.util.List;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;


@RestController
@RequestMapping("/health")
public class HealthController 

    private static final Logger LOGGER = LoggerFactory.getLogger(HealthController.class);
    
    @Autowired
    OptionRepository repository;
    
    @GetMapping("/id/options")
    public List<Health> findAllOptions(@PathVariable("id") Long id) 
        return (List<Health>) repository.findAll(id);
    
    
    @GetMapping("/id/valid/dates")
    public List<Health> findByDates(@PathVariable("id") Long id) 
        return repository.findDates(id);
    
    



@Data
class Health
    List<String> options;
    List<String> dates;

我的build.gradle如下

def logbackGatlingConfig() 
    return sourceSets.test.resources.find  it.name == 'logback-gatling.xml' 
 

bootJar  baseName = 'migroes-services' 

我的scala测试服如下

package com.dev
 
import io.gatling.core.scenario.Simulation
import io.gatling.core.Predef._
import io.gatling.http.Predef._
import java.util.Date
import scala.concurrent.duration.FiniteDuration
import scala.concurrent.duration.Duration
import java.util.concurrent.TimeUnit

class ApiGatlingSimulationTest extends Simulation 

  val scn = scenario("Dev Status").repeat(1000, "n") 
        exec(
          http("Get All Options")
            .get("http://localhost:8080/health/dev-001/options")
            .check(status.is(200))
        ).pause(Duration.apply(5, TimeUnit.MILLISECONDS))    
  .repeat(1000, "n") 
        exec(
          http("Valid Dates")
            .get("http://localhost:8090/health/dev-002/valid/dates")
            .check(status.is(200))
        )   
  
  
  setUp(scn.inject(atOnceUsers(30))).maxDuration(FiniteDuration.apply(10, "minutes"))
  

目前我从命令行收到以下错误。 我首先通过 STS 运行应用程序，然后尝试触发 gradle loadTest 命令。

我大部分时间都在错误以下。

线程 "main" io.gatling.core.session.el.E​​lParserException 中的异常：无法解析 VIN 并出现错误 'class [B cannot be cast to class [C ([B and [C are in module java.base加载程序'bootstrap'）'

我尝试在不同的平台上接触到几个不同的博客和类似的情况。到目前为止没有运气！！

【参考方案1】：

    testCompile('io.gatling.highcharts:gatling-charts-highcharts:2.3.0')

您正在尝试使用已死去多年的 Gatling 2。 请升级。目前最新版本为 3.5.1。

【讨论】：

嘿谢谢你，很抱歉很晚才回复你@Stephane 现在它对我有用。

太棒了！请注意，最新版本现在是 3.6.1 :)

哦，我去看看 BlackDuck 看看是否可行，感谢更新:)
