我已经下载了eclipse并在其中安装了spring suit。我已经按照www.example.com指南之一编写了一个基于JPA的Rest应用程序spring.io。当我尝试将其作为spring Boot 应用程序运行时,我得到了以下错误。
java.lang.NoSuchMethodError: com.google.gson.GsonBuilder.setLenient()Lcom/google/gson/GsonBuilder;
为什么会出现此错误?如何修复此错误?
下面是控制台的完整输出。

我会写这作为一个评论,但我仍然没有得到足够的代表。
问题一定是出在你的依赖项上。这里发生的是SpringBoot加载了GsonAutoConfiguration
@Configuration
类,它试图调用GsonBuilder
的setLenient()
方法。SpringBoot已经将正确的gson jar设置为依赖项,它应该自动包含在你的构建中;但是,显式地指定对gson的依赖性将覆盖SpringBoot带来的依赖性。最好的办法是从pom.xml(或build.gradle,或您使用的任何其他文件)中删除对gson的显式依赖关系,或者更新它以匹配您正在使用的SpringBoot版本所期望的依赖关系。
这是gson的最新版本,如果您使用的是SpringBoot的最新版本:
编辑:即使您没有在构建中显式声明gson,也可能发生另一个依赖项正在使用它的旧版本,并且它覆盖了SpringBoot所期望的版本。在这种情况下,我建议检查所有的依赖项,并确保版本排列一致。浏览一下Maven Central中列出的依赖项及其版本可能是一个好主意。

我也面临着同样的问题,不得不浪费很多时间来解决这个问题。
出现该问题的原因是,项目中已包含的现有依赖项的Gson库版本与Sping Boot 的默认依赖项版本不匹配。
这个问题最简单的解决方法(对我来说很有效)是替换
贴上
它基本上告诉 Boot 应用程序跳过Gson的自动配置。
此解决方案也适用于可能产生相同问题的任何其他类。您只需将每个此类冲突类的名称添加到EnableAutoConfiguration的exclude属性中。

我认为这个问题与Spring如何触发“AutoConfiguration”有关。在这个例子中,“GsonAutoConfiguration”在com.google.gson.Gson.class出现时被触发,即使你没有使用它,因为它有@ConditionalOnClass(value=Gson.class)注解。
因此,解决方案可能是删除具有Gson类的依赖项,或者删除特定的“AutoConfiguration”:
@启用自动配置(排除= {org.springframework.boot.autoconfigure.gson.GsonAutoConfiguration.class})
https://docs.spring.io/spring-boot/docs/current/api/org/springframework/boot/autoconfigure/gson/GsonAutoConfiguration.html

只需删除Maven依赖项的版本号。

好的,我遇到过同样的问题,问题是由于 Spring Boot 和gson之间的版本不匹配....解决方案是删除版本

您可以排除GsonAutoConfiguration
