Question

我正在使用Jmeter测试Spring Web服务。我们也在使用activiti，但由于我在两者都是新手，这就是我所知道的。据推测，该应用程序将从请求中接收参数。

然而，我在这里遇到了障碍（UpdateInbdParams）：

private String taskId;

private Map<String, String> vars;

public String getTaskId() {
    return taskId;
}

public void setTaskId(String taskId) {
    this.taskId = taskId;
}

public Map<String, String> getVars() {
    return vars;
}

public void setVars(HashMap<String, String> vars) {
    this.vars = vars;
}

我应该发送一个字符串和一个Map。后者应该如此，我们可以稍后发送我们需要的任何参数，而无需修改代码。但是我该如何测试后者呢？

返回：

{"vars":null}

供参考，以下是错误代码的一部分：

@RequestMapping(method = RequestMethod.POST)
public UpdateOutbdParams post(Locale locale, UpdateInbdParams model) {
    UpdateOutbdParams response = new UpdateOutbdParams();
    try{
        try{
            TaskService taskService = this.processEngine.getTaskService();
            Task task = taskService.createTaskQuery().taskId(model.getTaskId()).singleResult();
            RuntimeService runtimeService = this.processEngine.getRuntimeService();
            /** ERRORS HERE **/
            runtimeService.setVariables(task.getExecutionId(), model.getVars());
            /** ERRORS END HERE **/
            taskService.complete(model.getTaskId());
            System.out.println(model.getVars().toString());
            System.out.println("Task execution id " + task.getExecutionId());
        }catch(Exception ex){
            ex.printStackTrace();
            System.out.println("Inner catch: "+ex.getMessage());
        }
    }catch(Exception ex){
        ex.printStackTrace();
        System.out.println("Outer catch: "+ex.getMessage());
        return response;
    }
    return response;
}

这是实际的错误：

所以我猜它与它（如何）没有收到Map值有关。有什么想法吗？

感谢。

在Jmeter中，我如何测试地图值？
