How can I read a resource relative to the classpath ?

How can I read a resource relative to the classpath ?

You have to get the applicationcontext. I have blogged on this topic.

a) Create a resource that has a reference to a path

example :

    public org.springframework.core.io.Resource getResource() {
        logger.debug("entering getResource");
        org.springframework.core.io.Resource resource = applicationContext.getResource("classpath:telemetry/telemetrieA+Cons20090101_200906112209055.csv");
        logger.debug("leaving getResource");
        return resource;
    }

b) Read the resource

example :

CSVReader reader = new CSVReader(new FileReader(getResource().getFile()));

That's all folks !

How can I access the spring context ?

How can I access the spring context ?

There are 2 cases :

a) In an application
b) In a test application

a) In an application

1) You have to implement the interface ApplicationContextAware

example :

public class TelemetryConsumptionSynchronizer extends BaseSynchronizer implements ApplicationContextAware

2) Implementation of the method setApplicationContext

...
    ApplicationContext applicationContext;
...
    @Override
    public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
        logger.debug("entering setApplicationContext");
        this.applicationContext = applicationContext;
        logger.debug("leaving setApplicationContext");
    }

b) In a test application

It is more easy because you only have to inject the context.

example :

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(
        locations = {
                "classpath:el1EnergyCommSyncContextTest.xml"
        }
)
public class TelemetryConsumptionSynchronizerTest {
...
    @Resource
    private ApplicationContext applicationContext;
}
