Почему я получаю ошибку Gson builder при запуске приложения Spring Boot?
Я загрузил eclipse и установил в него весенний костюм. Я написал приложение отдыха на основе JPA, следуя одному из весны.IO направляющие. Когда я пытаюсь запустить его как приложение spring boot. 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.

Я бы написал это как комментарий, но у меня все еще недостаточно репутации.
проблема должна быть с зависимостями. Что здесь происходит то, что SpringBoot загружает GsonAutoConfiguration @Configuration
класс, который пытается вызвать GsonBuilder
' s setLenient()
метод. SpringBoot уже имеет правильный набор Gson jar как зависимость, которая должна автоматически включаться в вашу сборку; однако явное указание зависимости для gson переопределит приведенную зависимость по SpringBoot. Видимо, setLenient()
все еще не существует в версии gson, которую вы используете.
лучшее, что вы можете сделать, это либо удалить явную зависимость от gson из вашего pom.xml (или build.gradle, или что-то еще вы используете), или обновите его, чтобы соответствовать той, которая ожидается от используемой 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>
EDIT: он также может случается, что даже если вы не объявляете Gson явно в своей сборке, другая из ваших зависимостей использует более старую версию, и она переопределяет версию, которую ожидает SpringBoot. В этом случае, вместо того, чтобы пытаться грубой силы через проблему, я бы предложил пройти все ваши зависимости и убедиться, что версии выстраиваются в линию. Прохождение зависимостей и их версий, перечисленных в Maven Central может быть хорошей идеей.
я столкнулся с той же проблемой и приходилось тратить много времени, пытаясь исправить это.
проблема возникает из-за несоответствия версии библиотеки Gson существующим зависимостям, уже включенным в ваш проект, с зависимостью Spring Boot по умолчанию.
самое простое решение этой проблемы (которое сработало для меня) - заменить каждое вхождение
@EnableAutoConfiguration
тег
@EnableAutoConfiguration(exclude = {org.springframework.boot.autoconfigure.gson.GsonAutoConfiguration.class})
что в основном говорит приложению Spring boot пропустить автоматическая конфигурация для Gson.
это решение также применяется к любому другому классу, который может создать ту же проблему. Вам просто нужно добавить имя каждого такого конфликтующего класса в исключить на EnableAutoConfiguration.
