我正在使用Spring启动和Spring批处理。我已定义了多个工作。
我正在尝试构建junit来测试作业中的特定任务。
因此我正在使用JobLauncherTestUtils库。
当我运行我的测试用例时,我总是得到NoUniqueBeanDefinitionException。
这是我的测试类:
@RunWith(SpringJUnit4ClassRunner.class)
@SpringApplicationConfiguration(classes = {BatchConfiguration.class})
public class ProcessFileJobTest {
@Configuration
@EnableBatchProcessing
static class TestConfig {
@Autowired
private JobBuilderFactory jobBuilder;
@Autowired
private StepBuilderFactory stepBuilder;
@Bean
public JobLauncherTestUtils jobLauncherTestUtils() {
JobLauncherTestUtils jobLauncherTestUtils = new JobLauncherTestUtils();
jobLauncherTestUtils.setJob(jobUnderTest());
return jobLauncherTestUtils;
}
@Bean
public Job jobUnderTest() {
return jobBuilder.get("job-under-test")
.start(processIdFileStep())
.build();
}
@Bean
public Step processIdFileStep() {
return stepBuilder.get("processIdFileStep")
.<PushItemDTO, PushItemDTO>chunk(1) //important to be one in this case to commit after every line read
.reader(reader(null))
.processor(processor(null, null, null, null))
.writer(writer())
// .faultTolerant()
// .skipLimit(10) //default is set to 0
// .skip(MySQLIntegrityConstraintViolationException.class)
.build();
}
@Bean
@Scope(value = "step", proxyMode = ScopedProxyMode.INTERFACES)
public ItemStreamReader<PushItemDTO> reader(@Value("#{jobExecutionContext[filePath]}") String filePath) {
...
return itemReader;
}
@Bean
@Scope(value = "step", proxyMode = ScopedProxyMode.INTERFACES)
public ItemProcessor<PushItemDTO, PushItemDTO> processor(@Value("#{jobParameters[pushMessage]}") String pushMessage,
@Value("#{jobParameters[jobId]}") String jobId,
@Value("#{jobParameters[taskId]}") String taskId,
@Value("#{jobParameters[refId]}") String refId)
{
return new PushItemProcessor(pushMessage,jobId,taskId,refId);
}
@Bean
public LineMapper<PushItemDTO> lineMapper() {
DefaultLineMapper<PushItemDTO> lineMapper = new DefaultLineMapper<PushItemDTO>();
...
return lineMapper;
}
@Bean
public ItemWriter writer() {
return new someWriter();
}
}
@Autowired
protected JobLauncher jobLauncher;
@Autowired
JobLauncherTestUtils jobLauncherTestUtils;
@Test
public void processIdFileStepTest1() throws Exception {
JobParameters jobParameters = new JobParametersBuilder().addString("filePath", "C:\\etc\\files\\2015_02_02").toJobParameters();
JobExecution jobExecution = jobLauncherTestUtils.launchStep("processIdFileStep",jobParameters);
}
那就是例外:
Caused by: org.springframework.beans.factory.NoUniqueBeanDefinitionException: No qualifying bean of type [org.springframework.batch.core.Job] is defined: expected single matching bean but found 3: jobUnderTest,executeToolJob,processFileJob
有什么想法吗? 感谢。
添加了BatchConfiguration类:
package com.mycompany.notification_processor_service.batch.config;
import com.mycompany.notification_processor_service.common.config.CommonConfiguration;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.*;
import org.springframework.jdbc.core.JdbcTemplate;
import org.springframework.jdbc.datasource.DriverManagerDataSource;
import javax.sql.DataSource;
@ComponentScan("com.mycompany.notification_processor_service.batch")
@PropertySource("classpath:application.properties")
@Configuration
@Import({CommonConfiguration.class})
@ImportResource({"classpath:applicationContext-pushExecuterService.xml"/*,"classpath:si/integration-context.xml"*/})
public class BatchConfiguration {
@Value("${database.driver}")
private String databaseDriver;
@Value("${database.url}")
private String databaseUrl;
@Value("${database.username}")
private String databaseUsername;
@Value("${database.password}")
private String databasePassword;
@Bean
public DataSource dataSource() {
DriverManagerDataSource dataSource = new DriverManagerDataSource();
dataSource.setDriverClassName(databaseDriver);
dataSource.setUrl(databaseUrl);
dataSource.setUsername(databaseUsername);
dataSource.setPassword(databasePassword);
return dataSource;
}
@Bean
public JdbcTemplate jdbcTemplate(DataSource dataSource) {
return new JdbcTemplate(dataSource);
}
}
这是CommonConfiguration
@ComponentScan("com.mycompany.notification_processor_service")
@Configuration
@EnableJpaRepositories(basePackages = {"com.mycompany.notification_processor_service.common.repository.jpa"})
@EnableCouchbaseRepositories(basePackages = {"com.mycompany.notification_processor_service.common.repository.couchbase"})
@EntityScan({"com.mycompany.notification_processor_service"})
@EnableAutoConfiguration
@EnableTransactionManagement
@EnableAsync
public class CommonConfiguration {
}

我遇到了同样的问题,更简单的方法是注入JobLauncherTestUtils
的设置者,就像Mariusz在Jira of Spring中解释的那样:
@Bean public JobLauncherTestUtils getJobLauncherTestUtils() { return new JobLauncherTestUtils() { @Override @Autowired public void setJob(@Qualifier("ncsvImportJob") Job job) { super.setJob(job); } }; }

所以我看到了jobUnderTest bean。在所有这些导入中的某个地方,您还要导入另外两个作业。我看到你的BatchConfiguration
类导入了其他东西以及你打开了组件扫描。仔细追踪所有配置。有些东西正在为这些豆子定义。

我也遇到了这个问题,无法使JobLauncherTestUtils正常工作。它可能是由this issue
引起的我最终将SimpleJobLauncher和我的Job自动装入单元测试,并且只是
launcher.run(importAccountingDetailJob, params);

一篇旧帖子,但我想提供我的解决方案。
在这种情况下,我会自动注册每个作业JobLauncherTestUtils
@Configuration
public class TestConfig {
private static final Logger logger = LoggerFactory.getLogger(TestConfig.class);
@Autowired
private AbstractAutowireCapableBeanFactory beanFactory;
@Autowired
private List<Job> jobs;
@PostConstruct
public void registerServices() {
jobs.forEach(j->{
JobLauncherTestUtils u = create(j);
final String name = j.getName()+"TestUtils"
beanFactory.registerSingleton(name,u);
beanFactory.autowireBean(u);
logger.info("Registered JobLauncherTestUtils {}",name);
});
}
private JobLauncherTestUtils create(final Job j) {
return new MyJobLauncherTestUtils(j);
}
private static class MyJobLauncherTestUtils extends JobLauncherTestUtils {
MyJobLauncherTestUtils(Job j) {
this.setJob(j);
}
@Override // to remove @Autowire from base class
public void setJob(Job job) {
super.setJob(job);
}
}
}
