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
