Springfox-data-rest启动报错

今天使用Springfox-data-rest报错

[WARN ] 2019-03-28 15:44:16,218 org.springframework.boot.web.servlet.context.AnnotationConfigServletWebServerApplicationContext - Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'requestMappingHandlerAdapter' defined in class path resource [org/springframework/boot/autoconfigure/web/servlet/WebMvcAutoConfiguration$EnableWebMvcConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter]: Factory method 'requestMappingHandlerAdapter' threw exception; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.boot.autoconfigure.http.HttpMessageConvertersAutoConfiguration': Bean instantiation via constructor failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.boot.autoconfigure.http.HttpMessageConvertersAutoConfiguration$$EnhancerBySpringCGLIB$$3b178b30]: Constructor threw exception; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'halJacksonHttpMessageConverter' defined in class path resource [org/springframework/data/rest/webmvc/config/RepositoryRestMvcConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.hateoas.mvc.TypeConstrainedMappingJackson2HttpMessageConverter]: Factory method 'halJacksonHttpMessageConverter' threw exception; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'halObjectMapper' defined in class path resource [org/springframework/data/rest/webmvc/config/RepositoryRestMvcConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [com.fasterxml.jackson.databind.ObjectMapper]: Factory method 'halObjectMapper' threw exception; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'org.springframework.hateoas.hal.HalConfiguration' available

配置如下：

 <dependency>
      <groupId>io.springfox</groupId>
      <artifactId>springfox-data-rest</artifactId>
    </dependency>

@Configuration
@EnableSwagger2
@Import({SpringDataRestConfiguration.class, BeanValidatorPluginsConfiguration.class})
public class SwaggerConfiguration {

  @Bean
  public Docket createRestApi() {
    return new Docket(DocumentationType.SWAGGER_2)
      .select()
      .apis(RequestHandlerSelectors.basePackage("swust.qiy.microservice.management.controller"))
      .paths(PathSelectors.any())
      .build();
  }
}

查了一下找不到Bean的这个HalConfiguration所在的包hateoas

很奇怪的是一个项目里面为什么要依赖两次这个hateoas pom。。。然后就把这个hateoas exclusion掉，重新添加依赖

<dependency>
     <groupId>io.springfox</groupId>
     <artifactId>springfox-data-rest</artifactId>
     <exclusions>
       <exclusion>
         <groupId>org.springframework.hateoas</groupId>
         <artifactId>spring-hateoas</artifactId>
       </exclusion>
     </exclusions>
   </dependency>
   <dependency>
     <groupId>org.springframework.hateoas</groupId>
     <artifactId>spring-hateoas</artifactId>
     <version>0.24.0.RELEASE</version>
     <scope>compile</scope>
   </dependency>

然后启动。。成功。。。同时也一脸懵逼
