更正应用程序的类路径，使其包含一个兼容的 org.springframework.data.jpa.repository.config 版本

Question

我无法理解错误，我该怎么办？ 更正应用程序的类路径，使其包含一个兼容的 org.springframework.data.jpa.repository.config.JpaRepositoryConfigExtension 版本

Description:

An attempt was made to call a method that does not exist. The attempt was made from the following location:

    org.springframework.data.jpa.repository.config.JpaRepositoryConfigExtension.registerBeansForRoot(JpaRepositoryConfigExtension.java:169)

The following method did not exist:

    org.springframework.data.jpa.repository.config.JpaRepositoryConfigExtension.registerIfNotAlreadyRegistered(Lorg/springframework/beans/factory/support/AbstractBeanDefinition;Lorg/springframework/beans/factory/support/BeanDefinitionRegistry;Ljava/lang/String;Ljava/lang/Object;)V

The method's class, org.springframework.data.jpa.repository.config.JpaRepositoryConfigExtension, is available from the following locations:

    jar:file:/C:/Users/HCL/.m2/repository/org/springframework/data/spring-data-jpa/2.0.2.RELEASE/spring-data-jpa-2.0.2.RELEASE.jar!/org/springframework/data/jpa/repository/config/JpaRepositoryConfigExtension.class

It was loaded from the following location:

    file:/C:/Users/HCL/.m2/repository/org/springframework/data/spring-data-jpa/2.0.2.RELEASE/spring-data-jpa-2.0.2.RELEASE.jar


Action:

Correct the classpath of your application so that it contains a single, compatible version of org.springframework.data.jpa.repository.config.JpaRepositoryConfigExtension

我添加了最新版本的依赖项，尽管它会再次显示

请帮忙！

Answer 1

您不应提及spring-data-jpa 的版本。 Spring-boot 父依赖会自动解决。

而不是这个：

<dependency>
    <groupId>org.springframework.data</groupId>
    <artifactId>spring-data-jpa</artifactId>
    <! -- <version>2.0.2.RELEASE</version>  comment or remove this line -->
</dependency>

更新： 您使用的是spring-boot-starter-parent 版本2.2.4 和不同的spring-data-jpa 版本，这就是报错的原因。

Answer 2

你应该使用 spring-data-jpa 和 spring-boot-starter-jdbc：

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>

Answer 3

您应该参考 STS 执行以下步骤：

1. 在 build.graddle 中调整正确的依赖关系
2. 擦除缓存目录（通常在'C:\Users\your-name\.gradle\caches'）
3. 清理项目（主菜单>项目>清理...）
4. 在主java中右击Run as > Spring Boot App 或
5. 在 Project Explorer 中右键单击项目名称 > Gradle > 刷新 Gradle 项目

然后错误就会消失！

Answer 4

请使用给定的依赖项：

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.6.4</version> <!- use latest version -->
    <relativePath /> <!-- lookup parent from repository -->
</parent>

<dependencies>
    <dependency>
       <groupId>org.springframework.boot</groupId>
       <artifactId>spring-boot-starter-data-jpa</artifactId>
    </dependency>
</dependencies>

问题的发生是因为 pom.xml 中可用的依赖项版本不兼容，导致同一类的版本冲突。所以，从你的 pom 中删除显式版本声明，让 maven 从父 pom 的托管版本中解析依赖关系。
