我明白了

    java.lang.NoSuchFieldError: IMPORT_BEAN_NAME_GENERATOR
      at org.springframework.data.repository.config.RepositoryBeanDefinitionRegistrarSupport.registerBeanDefinitions(RepositoryBeanDefinitionRegistrarSupport.java:78)

尝试部署我的 Spring MVC 项目时出错。我读过这可能是暂时的依赖/冲突版本的原因，但是我无法弄清楚我的pom.xml 有什么问题。我想在为jwt 添加依赖项后我已经开始获得它，但是我检查了这些，它们似乎是最新的。这些是我拥有的依赖项：

感谢任何帮助。

【问题讨论】：

运行 mvn dependency:tree 并查看您最终得到了哪些依赖项。这显然是混合来自不同版本框架的 jar 的情况。 【参考方案1】：

混合使用不同版本的 spring-core、spring-web、spring-security 和 spring-jpa 通常会在运行时引发一些非常丑陋的错误。因此，最好使用以下方法将范围缩小到单个版本（托管版本）：

<properties>
  <spring-version>5.3.1.RELEASE</spring-version>
</properties>

在 pom.xml 文件的开头声明它，然后将它与 spring 依赖声明一起使用，如下所示：

    <!-- https://mvnrepository.com/artifact/org.springframework/spring-core -->
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-core</artifactId>
        <version>$spring-version</version>
    </dependency>

    <!-- https://mvnrepository.com/artifact/org.springframework.security/spring-security-web -->
    <dependency>
        <groupId>org.springframework.security</groupId>
        <artifactId>spring-security-web</artifactId>
        <version>$spring-version</version>
    </dependency>

    <!-- https://mvnrepository.com/artifact/org.springframework.data/spring-data-jpa -->
    <dependency>
        <groupId>org.springframework.data</groupId>
        <artifactId>spring-data-jpa</artifactId>
        <version>$spring-version</version>
    </dependency>

使用 mvn -U clean install 更新项目中使用的 maven jar。这些问题很可能应该会消失。

【参考方案2】：

这里发布了一个答案，但不知何故被删除了。答案是：将 spring 和 spring-security 核心依赖放在 pom 之上，以便所有其他依赖（包括 jwt 的）紧随其后。
