问题:

spring boot 2.6.x版本引入依赖springfox-boot-starter(swagger3.0) 后，启动容器会报错：

failed to start bean ‘ documentationpluginsbootstrapper ‘ ; nested exception…

原因

springfox 假设 springmvc的路径匹配策略是ant-path-matcher，而 spring boot 2.6.x版本的默认匹配策略是path-pattern-matcher，这就造成了上面的报错。

完整亚博vip888的解决方案:

1. pom配置

org.springframework.boot spring-boot-starter-web 2.6.4 io.springfox springfox-boot-starter 3.0.0

2. 添加bean

import org.springframework.beans.beansexception; import org.springframework.beans.factory.config.beanpostprocessor; import org.springframework.stereotype.component; import org.springframework.util.reflectionutils; import org.springframework.web.servlet.mvc.method.requestmappinginfohandlermapping; import springfox.documentation.spring.web.plugins.webfluxrequesthandlerprovider; import springfox.documentation.spring.web.plugins.webmvcrequesthandlerprovider; import java.lang.reflect.field; import java.util.list; import java.util.stream.collectors; @component public class swaggerbeanpostprocessor implements beanpostprocessor { @override public object postprocessafterinitialization(object bean, string beanname) throws beansexception { if (bean instanceof webmvcrequesthandlerprovider || bean instanceof webfluxrequesthandlerprovider) { list handlermappings = gethandlermappings(bean); customizespringfoxhandlermappings(handlermappings); } return bean; } private void customizespringfoxhandlermappings(list mappings) { list copy = mappings.stream() .filter(mapping -> mapping.getpatternparser() == null) .collect(collectors.tolist()); mappings.clear(); mappings.addall(copy); } @suppresswarnings("unchecked") private listhttp://www.cppcns.com gethandlermappings(object bean) { try { field field = reflectionutils.findfield(bean.getclass(), "handlermappings"); field.setaccessible(true); return (list) field.get(bean); } catch (illegalargumentexception | illegalaccessexception e) { throw new illegalstateexception(e); } } }

3. swagger配置类继承 webmvcconfigurationsupport

import org.springframework.context.annotation.bean; import org.springframework.context.annotation.configuration; import org.springframework.web.servlet.config.annotation.resourcehandlerregistry; import org.springframework.web.servlet.config.annotation.webmvcconfigurationsupport; import springfox.documentation.service.apiinfo; import springfox.documentation.spi.documentationtype; import springfox.documentation.spring.web.plugins.docket; @configuration public class swagger2config extends webmvcconfigurationsupport { @bean public docket createrestapi() { return new docket(documentationtype.swagger_2) .apiinfo(apiinfo.default); } @override public void addresourcehandlers(resourcehandlerregistry registry) { registry. addresourcehandler("/swagger-ui/**") .addresourcelocations("classpath:/meta-inf/resources/webjars/springfox-swagger-ui/") .resourcechain(false); } }

4. 访问 http://{ip}:{port}/swagger-ui/index.html

当然还是要感谢技术大佬,我只会汇总解决了治本的完整解决方法
