我已经下载了 eclipse 并将 spring suit 安装到其中。我按照其中一个 spring.io 指南编写了一个基于 JPA 的 Rest 应用程序。当我尝试将它作为 spring boot 应用程序运行时。我收到以下错误。
java.lang.NoSuchMethodError: com.google.gson.GsonBuilder.setLenient()Lcom/google/gson/GsonBuilder;
为什么会出现此错误？我该如何解决这个错误？
这是控制台的完整输出。

我会把它写成评论，但我仍然没有得到足够的代表。
问题一定出在您的依赖项上。这里发生的是 SpringBoot 加载 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，它应该自动包含在您的构建中；但是，显式指定对 gson 的依赖会覆盖 SpringBoot 带来的依赖。显然，setLenient()在您使用的 gson 版本中仍然不存在。你能做的最好的事情就是从你的 pom.xml（或 build.gradle，或你使用的任何其他东西）中删除对 gson 的显式依赖，或者更新它以匹配你正在使用的 SpringBoot 版本所期望的依赖。
如果您使用的是最新版本的 SpringBoot，这是最新版本的 gson：
编辑：即使您没有在构建中显式声明 gson，您的另一个依赖项也可能会使用它的旧版本，并且它会覆盖 SpringBoot 期望的版本。在那种情况下，我建议检查所有依赖项并确保版本一致，而不是尝试暴力解决问题。浏览 Maven Central 中 列出的依赖项及其版本可能是个好主意。
