Spring Boot 어플리케이션 부팅 시 Gson Builder 오류가 발생하는 이유는 무엇입니까?

이클립스를 다운받아 스프링 슈트를 설치했습니다.spring.io 가이드 중 하나에 따라 JPA 기반의 Rest 어플리케이션을 작성했습니다.spring boot 어플리케이션으로 실행하려고 하면.다음과 같은 에러가 발생.

java.lang.NoSuchMethodError: com.google.gson.GsonBuilder.setLenient()Lcom/google/gson/GsonBuilder;

이 에러가 발생하는 이유는 무엇입니까?이 오류를 수정하려면 어떻게 해야 하나요?

댓글로 쓰고 싶은데 아직 평판이 안 좋아요.

그 문제는 당신의 의존관계에 있는 것이 틀림없다.여기서 발생하는 것은 Spring Boot가 GsonAutoConfiguration을 로드하는 것입니다. @Configurationclass, 콜을 시도합니다.GsonBuildersetLenient()방법.Spring Boot에는 올바른 gson jar가 이미 포함되어 있어 자동으로 빌드에 포함되어야 합니다.단, gson에 대한 의존성을 명시적으로 지정하면 Spring Boot에 의해 초래된 의존성이 덮어쓰게 됩니다.듣자하니setLenient()사용하고 있는 gson 버전에는 아직 존재하지 않습니다.

가장 좋은 방법은 pom.xml(또는 build.gradle 또는 기타 사용 중인 모든 것)에서 gson에 대한 명시적 종속성을 제거하거나 사용 중인 SpringBoot 버전에서 예상되는 종속성에 맞게 업데이트하는 것입니다.

이것은 SpringBoot의 최신 버전을 사용하는 경우 gson의 최신 버전입니다.

<dependency>
    <groupId>com.google.code.gson</groupId>
    <artifactId>gson</artifactId>
    <version>2.8.2</version>
</dependency>

EDIT: 빌드에서 gson을 명시적으로 선언하지 않아도 다른 종속성 중 하나가 gson의 이전 버전을 사용하여 Spring Boot가 기대하는 버전을 덮어쓰는 경우도 있습니다.이 경우 문제를 강제로 해결하려는 것이 아니라 모든 종속성을 살펴보고 버전이 일치하는지 확인할 것을 제안합니다.메이븐 센트럴에 기재되어 있는 의존관계와 그 버전을 살펴보는 것이 좋을지도 모릅니다.

나는 같은 문제에 직면했고 이것을 고치느라 많은 시간을 허비해야만 했다.

이 문제는 프로젝트에 이미 포함되어 있는 기존 의존관계와 Spring Boot의 기본 의존관계와의 Gson 라이브러리의 버전이 일치하지 않기 때문에 발생합니다.

이 문제의 가장 쉬운 수정은 (나에게 효과가 있었던) 각 문제를

@EnableAutoConfiguration

을 붙이다.

@EnableAutoConfiguration(exclude = {org.springframework.boot.autoconfigure.gson.GsonAutoConfiguration.class})

기본적으로는 스프링 부트애플리케이션에 Gson의 자동 설정을 건너뛰도록 지시합니다.

이 솔루션은 같은 문제를 일으킬 수 있는 다른 클래스에도 적용됩니다.이러한 충돌하는 각 클래스의 이름을 Enable의 제외 속성에 추가하면 됩니다.자동 설정

이 문제는 스프링이 "AutoConfiguration"을 트리거하는 방식과 관련이 있다고 생각합니다.이 경우 "GsonAutoConfiguration"은 com.google.gson이 있을 때 트리거됩니다.Gson.class는 @ConditionalOnClass(value=Gson.class) 주석이 있기 때문에 사용하지 않는 경우에도 사용할 수 있습니다.

따라서 솔루션은 Gson 클래스의 의존관계를 삭제하거나 특정 "Auto Configuration"을 삭제합니다.

@EnableAutoConfiguration(= {syslog.springframework.boot.autoconfigure.gson 제외).GsonAutoConfiguration.class)

https://docs.spring.io/spring-boot/docs/current/api/org/springframework/boot/autoconfigure/gson/GsonAutoConfiguration.html

Maven 의존관계 버전 번호를 삭제하기만 하면 됩니다.

<dependency>
    <groupId>com.google.code.gson</groupId>
    <artifactId>gson</artifactId>
</dependency>

네, 같은 문제가 발생하였습니다.이 문제는 스프링 부트 및 gson의 버전이 일치하지 않기 때문입니다.해결 방법은 버전 삭제입니다.

GsonAutoConfiguration을 제외할 수 있습니다.

@SpringBootApplication(exclude = {org.springframework.boot.autoconfigure.gson.GsonAutoConfiguration.class})
