로컬에서는 잘돌아가는데 ec2 환경에서 BeanCreationException 에러가 납니다.

Question

상황은 제목과 같습니다. gpt에 물어본 결과 계속 스프링 부트 3.x 버전을 쓰면 자카르타를 써야하는데 javax 를 쓰고 있어서 오류가 나는 거다라고 답변을 하네요. 근데 그렇다면 로컬에서도 진작에 에러가 났어야 하는 상황이 아닌가 싶어서 속는 셈치고 javax를 자카르타로 전부 다 변경을 해주었더니 구동은 제대로 되는데 java.lang.NoSuchMethodError: 'void jakarta.servlet.http.Cookie.setAttribute(java.lang.String, java.lang.String) 뜨면서 로그인 후 리다이렉팅에서 막히더군요.사실 저는 후자의 방법보다 계속 검증을 해왔던 첫 번째 javax를 쓰는 프로그램으로 구동을 하고 싶은데 어떤 식으로 해결해야하는지 도와주시면 너무 감사하겠습니다. 빌드 파일, 에러로그 첨부하겠습니다. jar 추출은 bootjar로 하였습니다 !빌드 파일 :plugins {id 'java'id 'org.springframework.boot' version '3.2.4'id 'io.spring.dependency-management' version '1.1.4'}group &#61; 'org.example'version &#61; '0.0.1-SNAPSHOT'java {sourceCompatibility &#61; '17'}configurations {compileOnly {extendsFrom annotationProcessor}}repositories {mavenCentral()}dependencies {implementation 'io.jsonwebtoken:jjwt-api:0.12.3'implementation 'io.jsonwebtoken:jjwt-impl:0.12.3'implementation 'io.jsonwebtoken:jjwt-jackson:0.12.3'implementation 'org.springframework.boot:spring-boot-starter-data-jpa'implementation 'org.springframework.boot:spring-boot-starter-oauth2-client'implementation 'org.springframework.boot:spring-boot-starter-security'implementation 'org.springframework.boot:spring-boot-starter-web'implementation 'org.springframework.cloud:spring-cloud-starter-aws:2.2.6.RELEASE'compileOnly 'javax.servlet:javax.servlet-api:4.0.1'compileOnly 'org.projectlombok:lombok'runtimeOnly 'com.mysql:mysql-connector-j'annotationProcessor 'org.projectlombok:lombok'testImplementation 'org.springframework.boot:spring-boot-starter-test'testImplementation 'org.springframework.security:spring-security-test'}tasks.named('test') {useJUnitPlatform()}오류 로그 :Error starting ApplicationContext.

spring 3.x에서 javax대신 jakarta를 쓰는건 선택사항이 아닙니다. 무조건 자카르타로 써야해요.그러면서 미묘하게 바뀐 스펙이 있을것입니다. 그 스펙도 맞게 변경하셔야죠.오류내용자체는mypageController에서 파라미터로 받는 request가 javax의 request로 import되어있는데 javax class를 못찾는다는 내용이내요. 자카르타로 바꾸셔야합니다.

로컬에서는 잘돌아가는데 ec2 환경에서 BeanCreationException 에러가 납니다.
