我已经下载了eclipse并将弹簧套装安装到其中。 我按照spring.io指南之一编写了一个基于JPA的Rest应用程序。当我尝试将其作为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;
为什么我收到此错误？如何解决此错误？
以下是控制台的完整输出。

答案 0 :(得分：23)
我会把它写成评论，但我仍然没有足够的代表。
问题必须与您的依赖项有关。这里发生的是SpringBoot加载GsonAutoConfiguration @Configuration类，它尝试调用GsonBuilder的{{1}}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，显式指定对gson的依赖关系将覆盖SpringBoot带来的依赖关系。显然，setLenient()仍然不存在于您使用的gson版本中。
您可以做的最好的事情是从pom.xml（或build.gradle，或者您使用的任何其他内容）中删除对gson的显式依赖项，或者更新它以匹配您所使用的SpringBoot版本所期望的依赖项。使用
这是gson的最新版本，如果您使用的是最新版本的SpringBoot：
setLenient()编辑：也可能发生这种情况，即使你没有在你的构建中明确声明gson，你的另一个依赖项是使用它的旧版本，它会覆盖SpringBoot期望的版本。在这种情况下，我建议不要试图通过问题来强制执行所有依赖项，并确保版本排列。浏览Maven Central中列出的依赖项及其版本可能是一个好主意。
答案 1 :(得分：7)
我遇到了同样的问题，不得不浪费大量时间来解决这个问题。
问题出现是由于Gson库与已经包含在项目中的现有依赖项的版本不匹配与Spring Boot的默认版本不匹配。
此问题的最简单修复（对我有用）是替换每次出现的
@EnableAutoConfiguration
标记
@EnableAutoConfiguration(exclude = {org.springframework.boot.autoconfigure.gson.GsonAutoConfiguration.class})
基本上告诉Spring启动应用程序跳过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 的排除属性中。
答案 2 :(得分：2)
我认为问题与Spring如何触发“自动配置”有关。在这种情况下，即使您没有使用com.google.gson.Gson.class，也会触发“ GsonAutoConfiguration”，因为它具有@ConditionalOnClass（value = Gson.class）批注。
因此，解决方案可能是删除具有Gson类的依赖项或删除特定的“ AutoConfiguration”：
@EnableAutoConfiguration（排除= {org.springframework.boot.autoconfigure.gson.GsonAutoConfiguration.class}）
答案 3 :(得分：1)
您可以排除GsonAutoConfiguration
@SpringBootApplication(exclude = {org.springframework.boot.autoconfigure.gson.GsonAutoConfiguration.class})
答案 4 :(得分：0)
好的，我遇到了同样的问题，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

答案 5 :(得分：0)
只需删除 Maven 依赖项的版本号即可。
