Почему я получаю ошибку Gson builder при запуске приложения Spring Boot?

Я загрузил eclipse и установил в него костюм spring. Я написал приложение для отдыха на основе JPA, следуя одному из руководств spring.io. Когда я пытаюсь запустить его как приложение загрузки spring. Я получаю следующую ошибку.

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

Почему я получаю эту ошибку? Как исправить эту ошибку?

Вот полный вывод с консоли.

Ответ 1

Я написал бы это как комментарий, но у меня все еще не хватает представителя.

Проблема должна быть с вашими зависимостями. Здесь происходит то, что SpringBoot загружает класс GsonAutoConfiguration @Configuration, который пытается вызвать GsonBuilder setLenient(). SpringBoot уже установил правильный gson jar как зависимость, которая должна автоматически включаться в вашу сборку; однако, явное указание зависимости от gson переопределит зависимость, принесенную SpringBoot. По-видимому, setLenient() все еще не существовало в используемой версии gson.

Лучшее, что вы можете сделать, - это либо удалить явную зависимость от gson из вашего pom.xml (или build.gradle, либо из того, что вы используете), либо обновить его, чтобы он соответствовал тому, который ожидается в используемой вами версии SpringBoot.

Это самая последняя версия gson, если вы используете последнюю версию SpringBoot:

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

РЕДАКТИРОВАТЬ: может также случиться так, что даже если вы не объявите gson явно в вашей сборке, другая из ваших зависимостей использует более старую версию, и она переопределяет версию, которую ожидает SpringBoot. В этом случае, вместо того, чтобы пытаться решить проблему, я бы предложил пройтись по всем вашим зависимостям и убедиться, что версии совпадают. Хорошей идеей может быть просмотр зависимостей и их версий, перечисленных в Maven Central.

Я столкнулся с той же проблемой, и мне пришлось потратить много времени, пытаясь это исправить.

Проблема возникает из-за несоответствия версий библиотеки Gson существующим зависимостям, уже включенным в ваш проект, с установленной по умолчанию версией Spring Boot.

Самым простым решением этой проблемы (которое сработало для меня) является замена каждого вхождения

@EnableAutoConfiguration

пометить с

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

который в основном говорит загрузочному приложению Spring пропустить автоматическую настройку для Gson.

Это решение также применимо к любому другому классу, который может создать такую же проблему. Вам просто нужно добавить имя каждого такого противоречивого класса до исключения атрибута EnableAutoConfiguration.

Я думаю, что проблема связана с тем, как Spring вызывает "Автоконфигурацию". В этом случае "GsonAutoConfiguration" запускается при наличии com.google.gson.Gson.class, даже если вы его не используете, так как он имеет аннотацию @ConditionalOnClass (value = Gson.class).

Таким образом, решение может быть либо удалением зависимости, имеющей класс Gson, либо удалением определенной "Автоконфигурации":

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

Хорошо, та же проблема, с которой я столкнулся, проблема из-за несоответствия версий между весенней загрузкой и gson.... решение - удалить версию

    <groupId>org.springframework.boot</groupId>

    <relativePath /> <!-- lookup parent from repository -->
