java读取properties配置文件中的内容

首先在resource目录下创建一个error的目录，properties配置文件放在error目录中，如下图所示：

读取

@ControllerAdvice
@Slf4j
public class DefaultRestControllerExceptionHandler {	

	private Properties httpStatusErrorMap;

	@PostConstruct
	private void initHttpStatusErrorMap() {
		httpStatusErrorMap = new Properties();
		try {
			InputStream in = DefaultRestControllerExceptionHandler.class.getResourceAsStream("/error/httpStatus.properties");

			if (in != null) {
				Properties tempProperties = new Properties();
				tempProperties.load(in);
				httpStatusErrorMap.putAll(tempProperties);
			}
		} catch (IOException e) {
			log.error("{}",e.getMessage(), e.fillInStackTrace());
			throw new SystemException("IOException", e);
		}
	}

}
