build를 했는데 publicIPs에 8080 포트를 주소에 입력하면 "연결을 거부했습니다." 라는 문구가 뜹니다.8080 포트가 쓰이지 않는 거 같아 cat nohup.out을 입력해보면 org.postgresql.util.PSQLException: FATAL: password authentication failed for user "jjeong" at org.postgresql.core.v3.ConnectionFactoryImpl.doAuthentication(ConnectionFactoryImpl.java:693) ~[postgresql-42.6.0.jar!/:42.6.0] org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in class path resource [org/springframework/boot/autoconfigure/orm/jpa/HibernateJpaConfiguration.class]: [PersistenceUnit: default] Unable to build Hibernate SessionFactory; nested exception is org.hibernate.exception.GenericJDBCException: Unable to open JDBC Connection for DDL execution [FATAL: password authentication failed for user "jjeong"] [n/a] application.properties#datasource spring.datasource.driver-class-name=org.postgresql.Driver spring.datasource.url=jdbc:postgresql://localhost:5432/membercertification spring.datasource.username=jjeong spring.datasource.password=0525url, username, password가 다 들어맞는 것도 확인했습니다. build.gradledependencies { implementation 'org.springframework.boot:spring-boot-starter-security' implementation 'org.springframework.boot:spring-boot-starter-web' implementation 'org.springframework.boot:spring-boot-starter-thymeleaf' implementation 'org.springframework.boot:spring-boot-starter-data-jpa' implementation 'org.modelmapper:modelmapper:3.1.0' implementation 'org.thymeleaf.extras:thymeleaf-extras-springsecurity6:3.1.2.RELEASE' // implementation 'org.hibernate.orm:hibernate-core:6.2.6.Final' compileOnly 'org.projectlombok:lombok' runtimeOnly 'org.postgresql:postgresql' annotationProcessor 'org.springframework.boot:spring-boot-configuration-processor' annotationProcessor 'org.projectlombok:lombok' testImplementation 'org.springframework.boot:spring-boot-starter-test' testImplementation 'org.springframework.security:spring-security-test' testImplementation 'org.junit.jupiter:junit-jupiter-api:5.10.0' testRuntimeOnly 'org.junit.jupiter:junit-jupiter-engine:5.10.0' testRuntimeOnly 'org.junit.platform:junit-platform-launcher' developmentOnly 'org.springframework.boot:spring-boot-devtools' } 어디가 문제인지 모르겠습니다 ㅠㅠ
