java - 如何将 JobParameters 传递给 Spring Batch Junit 测试用例 JobLauncherTestUtils？

Question

我是 Spring Batch 的新手，我有一个以下主程序，我想使用 jobLauncherTestUtils 将其转换为测试用例。我们怎样才能做到这一点？

我关注了http://docs.spring.io/spring-batch/reference/html/testing.html ，但我没有看到任何指针。请指导。

private void run() {
        String[] springConfig = { "spring/batch/jobs/job-extract-users.xml" };
        ApplicationContext context = new ClassPathXmlApplicationContext(springConfig);

        JobLauncher jobLauncher = (JobLauncher) context.getBean("jobLauncher");
        Job job = (Job) context.getBean("testActualJob");

        try {
            JobParameters param = new JobParametersBuilder().addString("age", "20").toJobParameters();

            JobExecution execution = jobLauncher.run(job, param);
            System.out.println("----------------------------------------------");
            System.out.println("Exit Status : " + execution.getStatus());
            System.out.println("Exit Status : " + execution.getAllFailureExceptions());
            System.out.println("-----------------------------------------------");
        } catch (Exception e) {
            e.printStackTrace();
        }

        System.out.println("Done !!");
    }

引自documentation :-

The launchJob() method is provided by the JobLauncherTestUtils class. Also provided by the utils class is launchJob(JobParameters), which allows the test to give particular parameters.

您的代码如下所示:-

JobParameters param = new JobParametersBuilder().addString("age", "20").toJobParameters();
 JobExecution jobExecution = jobLauncherTestUtils.launchJob(param).getStatus();
