Spring - change bean definition from XML to annotation

Question

I have a working spring application. Beans are defined in applicationContext.xml.

applicationContext.xml

<bean name="reportFileA" class="com.xyz.ReportFile"> <property name="resource" value="classpath:documents/report01.rptdesign" /> </bean>

reportFile class

public class ReportFile { private File file; public void setResource(Resource resource) throws IOException { this.file = resource.getFile(); } public File getFile() { return file; } public String getPath() { return file.getPath(); } }

usage in a java class

@Resource(name = "reportFileA") @Required public void setReportFile(ReportFile reportFile) { this.reportFile = reportFile; }

This works fine. But now i want to get ride of the bean declartion in xml. How can i make this only with annotations?

The ReportFile class is imported from another own Spring Project.

I am trying to migrate my spring application to spring boot. And i want no more xml configuration.

Possible Solution:

@Bean(name="reportFileA") public ReportFile getReportFile() { ReportFile report = new ReportFile(); try { report.setResource(null); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } return report; }

Or add @Component("reportFileA") to the class declaration. Don't know about the property though. — daniu

In order to inject the Resource to your bean use the ResourceLoader , Try the below code :

@Configuration public class MySpringBootConfigFile { /*..... the rest of config */ @Autowired private ResourceLoader resourceLoader; @Bean(name = "reportFileA") public ReportFile reportFileA() { ReportFile reportFile = new ReportFile(); Resource ressource = resourceLoader.getResource("classpath:documents/report01.rptdesign"); try { reportFile.setResource(ressource); } catch (IOException e) { e.printStackTrace(); } return reportFile; } /* ...... */ }
