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;
	}
