저는 REST API에 연결하여 응답을 보는 데 사용하는 간단한 스프링 부팅 응용 프로그램이 있습니다. 프로토 타이핑을위한 간단한 앱입니다. 그러나 나는 다음과 같은 오류 받고 있어요 :봄 부트 클래스 def가 발견되지 않았습니다. 오류

을 나는 클래스 계정을 정의했기 때문에 아무 생각이 왜 발생하는하지 않습니다이 또 다른 문제점은 application.properties에 정의한 "apiforest.baseuri"키의 값을 가져 오지 않는 것입니다.
내 application.properties :
spring.jpa.hibernate.ddl-auto=create
spring.datasource.url=jdbc:mysql://localhost:3306/SampleDB
spring.datasource.username=root
spring.datasource.password=admin
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect
management.port = 9001
apiforest.baseuri = https://api-forest/....
read.timeout = 10000
connect.timeout = 10000
내 RestConfig :
package com.crossover.techtrial.java.se.config;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.http.client.ClientHttpRequestFactory;
import org.springframework.http.client.HttpComponentsClientHttpRequestFactory;
import org.springframework.web.client.RestTemplate;
// To set the configuration parameters like read timeout and connect timeout for Rest Client
@Configuration
public class RestConfig
{
@Bean
public RestTemplate createRestTemplate(final ClientHttpRequestFactory clientHttpRequestFactory)
{
return new RestTemplate(clientHttpRequestFactory);
}
@Bean
public ClientHttpRequestFactory createClientHttpRequestFactory(@Value("${connect.timeout}") final int connectTimeout,
@Value("${read.timeout}") final int readTimeout)
{
HttpComponentsClientHttpRequestFactory factory = new HttpComponentsClientHttpRequestFactory();
factory.setConnectTimeout(connectTimeout);
factory.setReadTimeout(readTimeout);
return factory;
}
