Read application.properties Using the Environment

environment application.properties java autowired 5 years, 2 months ago

import org.springframework.beans.factory.annotation.Autowired; import org.springframework.core.env.Environment; import org.springframework.web.bind.annotation.GetMapping; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestParam; import org.springframework.web.bind.annotation.RestController; @RestController @RequestMapping("app") public class AppController { @Autowired private Environment env; @GetMapping("/property") public String getPropertyValue(@RequestParam("key") String key) { String returnValue = "No value"; String keyValue = env.getProperty(key); if( keyValue!= null && !keyValue.isEmpty()) { returnValue = keyValue; } return returnValue; } }

Here, we are using @Autowired annotation to inject the environment object into our RestController , we can use it in Service class also.
User getProperty(String key) method to get a value for a specific property from application.properties.
Finally, we need to create a Web Service endpoint that accepts property key name as request parameter and returns property value.
