我有一个接口实现，它将我的请求Map到 JobParameters ```
@Component("myMapper")
public class MyMapper implements RequestMapper {

@Override
public JobParameters map(Request request) {
    JobParametersBuilder parameters = new JobParametersBuilder();
    parameters.addString("name", request.getValue(NAME));
    parameters.addString("test", request.getValue(TEST));
    return parameters.toJobParameters();
}

}

在我的jobrunner类中，我必须在执行作业之前添加一个不在请求对象中的附加参数：

public Response runJob(final Request request, final String id) {
Job job = getJob(request);
JobParameters parameters = myMapper.map(request);

//i want to add id to parameters
JobExecution execution;

    execution = jobLauncher.run(job, parameters);

}

如何添加此新参数？
