应用程序运行失败 org.springframework.beans.factory.BeanDefinitionStoreException：无法读取候选组件类：

Question

添加 Swagger 依赖项和 Swagger Config 类后，我收到此错误：

[main] ERROR org.springframework.boot.SpringApplication - Application run failed
org.springframework.beans.factory.BeanDefinitionStoreException: Failed to read candidate component class: URL [jar:file:/C:/mule/.m2/repository/io/springfox/springfox-swagger2/3.0.0/springfox-swagger2-3.0.0.jar!/springfox/documentation/swagger2/web/Swagger2ControllerWebMvc.class]; nested exception is java.lang.IllegalArgumentException: Could not find class [springfox.documentation.spring.web.OnServletBasedWebApplication]  

下面是 Swagger Config 类：

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurationSupport;

import springfox.documentation.builders.PathSelectors;
import springfox.documentation.builders.RequestHandlerSelectors;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2;

@Configuration
@EnableSwagger2
public class SpringFoxConfig extends WebMvcConfigurationSupport {                                    
    @Bean
    public Docket api() { 
        return new Docket(DocumentationType.SWAGGER_2)
                .select()
                .apis(RequestHandlerSelectors.basePackage(                                            
                    "com.sample.controller"))
                .paths(PathSelectors.any())
                .build();
                                                
    }
}

我在这个 Spring 启动版本的 POM 文件中添加了这些依赖项。我也有一些本地存储库链接。我不得不删除该链接。在添加 Swagger 依赖项之前，它正在运行并提供输出。

Answer 1

更正应用程序的类路径，使其包含一个兼容的 org.springframework.plugin.core.PluginRegistry 版本

或者你可以检查使用Swagger的问题你不应该说swagger version

 <dependency>
   <groupId>io.springfox</groupId>
   <artifactId>springfox-swagger2</artifactId>
</dependency>

如果失败，你可以参考这个github链接：解决的问题 https://github.com/springfox/springfox/issues/2932
