SpringBoot3引入knife4j和knife4j文档请求异常

复制粘贴即可

1.第一步pom文件中：

<dependency>
<groupId>com.github.xiaoymin</groupId>
<artifactId>knife4j-openapi3-jakarta-spring-boot-starter</artifactId>
<version>4.4.0</version>
</dependency>

2.第二步在 application.yml中

# springdoc-openapi项目配置
springdoc:
  swagger-ui:
    path: /swagger-ui.html
    tags-sorter: alpha
    operations-sorter: alpha
  api-docs:
    path: /v3/api-docs
  group-configs:
    - group: 'default'
      paths-to-match: '/**'
      packages-to-scan: com.xiaominfo.knife4j.demo.web 注意这里改成自己的controller包的路径
# knife4j的增强配置，不需要增强可以不配
knife4j:
  enable: true
  setting:
    language: zh_cn

启动工程，打开http://localhost:8080/doc.html ,我的启动的端口是8080

knife4j文档请求异常

原因：我们在进行对发送的请求拦截，没有把knife4j相应的端口放开

在注册拦截器里面放开即可

  @Overridepublic void addInterceptors(InterceptorRegistry registry) {registry.addInterceptor(loginInterceptors).
addPathPatterns("/**").
excludePathPatterns("/user/login","/user/register","/v3/api-docs/**", "/swagger-ui/**");}
