场景复现：

• knife4j-openapi3-jakarta-spring-boot-starter版本

  com.github.xiaoymin knife4j-openapi3-jakarta-spring-boot-starter 4.5.0

• 原来使用springboot3.3.5版本，先升级到3.4.0版本

• 通过http://ip:port/doc.html访问接口文档发现访问/v3/api-docs接口时报

  Handler dispatch failed: java.lang.NoSuchMethodError: 'void org.springframework.web.method.ControllerAdviceBean.(java.lang.Object)

通过分析异常日志发现是ControllerAdviceBean类报错，在springboot3.3.5时spring-web版本是6.1.14，springboot3.4版本是6.2.0版本。

通过springboot全局异常捕获堆栈信息发现：

org.springdoc.core.service.GenericResponseService.lambda$getGenericMapResponse$8(GenericResponseService.java:702)

GenericResponseService类是在如下包：

<!-- https://mvnrepository.com/artifact/org.springdoc/springdoc-openapi-starter-common --> <dependency> <groupId>org.springdoc</groupId> <artifactId>springdoc-openapi-starter-common</artifactId> <version>2.3.0</version> </dependency>

GenericResponseService类的702行代码如下(ControllerAdviceBean类使用一个参数的构造函数，但是报异常)：

List<ControllerAdviceInfo> controllerAdviceInfosNotInThisBean = controllerAdviceInfos.stream() .filter(controllerAdviceInfo -> new ControllerAdviceBean(controllerAdviceInfo.getControllerAdvice()).isApplicableToBeanType(beanType)) .filter(controllerAdviceInfo -> !beanType.equals(controllerAdviceInfo.getControllerAdvice().getClass())) .toList();

spring-web6.1.14版本中ControllerAdviceBean的构造函数：

public ControllerAdviceBean(Object bean) { Assert.notNull(bean, "Bean must not be null"); this.beanOrName = bean; this.isSingleton = true; this.resolvedBean = bean; this.beanType = ClassUtils.getUserClass(bean.getClass()); this.beanTypePredicate = createBeanTypePredicate(this.beanType); this.beanFactory = null; }

spring-web6.2.0版本中ControllerAdviceBean的构造函数：

public ControllerAdviceBean(String beanName, BeanFactory beanFactory, ControllerAdvice controllerAdvice) { Assert.hasText(beanName, "Bean name must contain text"); Assert.notNull(beanFactory, "BeanFactory must not be null"); Assert.isTrue(beanFactory.containsBean(beanName), () -> "BeanFactory [" + beanFactory + "] does not contain specified controller advice bean '" + beanName + "'"); Assert.notNull(controllerAdvice, "ControllerAdvice must not be null"); this.beanName = beanName; this.isSingleton = beanFactory.isSingleton(beanName); this.beanType = getBeanType(beanName, beanFactory); this.beanTypePredicate = createBeanTypePredicate(controllerAdvice); this.beanFactory = beanFactory; }

此类中的构造函数已经变更为4个，已经不存在一个参数的构造函数了。

• springdoc-openapi-starter-common文档当前已经升级到2.7.0版本

  org.springdoc springdoc-openapi-starter-common 2.7.0

结论：期待knife4j-openapi3-jakarta-spring-boot-starter早日升级，兼容最新版本的spring;
