NoSuchBeanDefinitionException：没有类型为JobLauncher的限定bean来自动装配

标签： java spring spring-mvc spring-batch autowired

我正在关注this spring batch tutorial。现在，我想运行一个API，所以我把它作为一个Web项目＆amp;在控制器之后实现，但bean没有自动装配。

examples.spring.batch.web.controller.JobLauncherController 

@Controller
@RequestMapping("/run")
public class JobLauncherController {

  @Autowired
  private JobLauncher jobLauncher;

  @Autowired
  private Job job;

  @RequestMapping(method = RequestMethod.GET, value = "/runJob")
  @ResponseBody
  public void launchImportDataJob() throws Exception {
    jobLauncher.run(importDataJob, new JobParameters());
  }
}

在加载applicationContext.xml

的web.xml上使用Spring侦听器 
<listener>
     <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

答案 1 :(得分：0)

在我的Application类中使用以下工作，而不必弄乱web.xml（我甚至没有在我的项目中有一个）：

@EnableAutoConfiguration
@Configuration
@ImportResource({"classpath*:applicationContext.xml"})

另见Spring-boot automatically import applicationContext.xml?

或使用更简洁的版本

@SpringBootApplication
@ImportResource("applicationContext.xml")

Loading applicationcontext.xml when using SpringApplication
