为什么我在启动Spring Boot应用程序时收到Gson构建器错误?

2022-09-01 10:09:19

我已经下载了eclipse并将弹簧服安装到其中。我按照 spring.io 指南之一编写了基于JPA的Rest应用程序。当我尝试将其作为弹簧启动应用程序运行时。我收到以下错误。

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

为什么我会收到此错误?如何修复此错误?

下面是控制台的完整输出。

答案 1

我会写这个作为评论,但我仍然没有足够的代表。

问题一定出在您的依赖项上。这里发生的事情是SpringBoot加载GsonAutoConfiguration类,该类尝试调用的方法。SpringBoot已经将正确的gson jar设置为依赖项,该依赖项应自动包含在您的构建中;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,在您正在使用的gson版本中仍然存在。@ConfigurationGsonBuildersetLenient()setLenient()

你能做的最好的事情就是从你的pom.xml(或build.gradle,或者你使用的任何其他东西)中删除对gson的显式依赖关系,或者更新它以匹配你正在使用的SpringBoot版本所期望的依赖关系。

这是gson的最新版本,如果您使用的是最新版本的SpringBoot:

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

编辑:即使您没有在构建中显式声明gson,也可能发生这种情况,您的另一个依赖项正在使用它的旧版本,并且它覆盖了SpringBoot期望的版本。在这种情况下,我建议不要试图暴力破解问题,而是要遍历所有依赖项并确保版本对齐。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 2

我遇到了同样的问题,不得不浪费很多时间试图解决这个问题。

由于Gson库与项目中已包含的现有依赖项的版本与Spring Boot的默认依赖项的版本不匹配,因此出现了问题。

此问题的最简单解决方法(对我有用)是替换每个出现的

@EnableAutoConfiguration

标记中

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

这基本上告诉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“启用自动配置”exclude 属性中即可。
