An attempt was made to call a method that does not exist. The attempt was made from the following location:\n\n    org.webjars.WebJarAssetLocator.scanForWebJars(WebJarAssetLocator.java:183)\n\nThe following method did not exist:\n\n    \'io.github.classgraph.ClassGraph io.github.classgraph.ClassGraph.acceptPaths(java.lang.String[])\'\n\nThe calling method\'s class, org.webjars.WebJarAssetLocator, was loaded from the following location:\n\n    jar:file:/home/gabriel/.m2/repository/org/webjars/webjars-locator-core/0.50/webjars-locator-core-0.50.jar!/org/webjars/WebJarAssetLocator.class\n\nThe called method\'s class, io.github.classgraph.ClassGraph, is available from the following locations:\n\n    jar:file:/home/gabriel/.m2/repository/io/github/classgraph/classgraph/4.8.69/classgraph-4.8.69.jar!/io/github/classgraph/ClassGraph.class\n\nThe called method\'s class hierarchy was loaded from the following locations:\n\n    io.github.classgraph.ClassGraph: file:/home/gabriel/.m2/repository/io/github/classgraph/classgraph/4.8.69/classgraph-4.8.69.jar\n\n\nAction:\n\nCorrect the classpath of your application so that it contains compatible versions of the classes org.webjars.WebJarAssetLocator and io.github.classgraph.ClassGraph\n

这是我的 pom.xml

我可以解决这个问题吗？

Answer 1

的传递依赖项不兼容org.springdoc:springdoc-openapi-ui。这取决于两者org.webjars:webjars-core-locator，io.github.classgraph:classgraph但它们的版本不兼容。

Spring Boot 的依赖管理webjars-core-locator使用 version 0.50。webjars-core-locator 0.50默认情况下会使用classgraph 4.8.139，但由于 Maven 解决版本冲突的方式，它被降级为4.8.69.

您可以通过在现有的导入旁边4.8.139添加一些依赖项管理来恢复使用来解决该问题：pom.xmlspring-cloud-dependencies

<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-dependencies</artifactId>
            <version>${spring-cloud.version}</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency>
        <dependency>
            <groupId>io.github.classgraph</groupId>
            <artifactId>classgraph</artifactId>
            <version>4.8.139</version>
        </dependency>
    </dependencies>
</dependencyManagement>

Answer 2

将以下实现添加到 build.gradle 文件也可以解决该问题：implementation('org.springdoc:springdoc-openapi-ui:1.6.9')

Answer 3

正如其他答案中所述，确实是 springdoc-openapi-ui 在这里制造麻烦。我遇到了有关 WebJarAssetLocator 和/或 ClassGraph 的各种错误，这些错误都通过更新 springdoc 解决了。

现在，有了 spring-boot 2.7.2 和 spring-doc 1.6.9，一切又恢复顺利了。

Answer 4

我已修复将 springdoc-openapi-ui 升级到 1.6.12
