For accessing single value can be used Spring annotations "PropertySource" and "Value".
@PropertySource("classpath:application.properties")
public class SomeClass {
@Value("${some.property}")
private String someProperty;
...
}
For accessing/looping all spring properties, check this solution looping-through-all-the-properties-in-a-file-with-spring-and-java
Controller sample code:
@RestController
public class PropertiesController {
@Autowired
Properties props;
@RequestMapping(value = {"/properties"}, method = RequestMethod.GET, produces= MediaType.APPLICATION_JSON_UTF8_VALUE)
public Set<Map.Entry<Object, Object>> getProperties() {
return props.entrySet();
}
}

In case if providing all application properties via rest interface be careful not to share sensitive data: URL's, connection parameters, etc. It is better to filter necessary parameters only by creating custom List.
if you are Using spring-boot then add spring-actuator dependency which by defaults expose /env endpoint and spits out all the properties loaded in the spring container in json format.
