springboot3.2.0

knife4j的jar包

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

解决办法：

设置静态资源映射

继承WebMvcConfigurationSupport ，实现addResourceHandlers方法

完整代码如下：

package com.demo2.config;import io.swagger.v3.oas.models.Components;
import io.swagger.v3.oas.models.OpenAPI;
import io.swagger.v3.oas.models.info.Info;
import io.swagger.v3.oas.models.info.License;
import io.swagger.v3.oas.models.security.OAuthFlow;
import io.swagger.v3.oas.models.security.OAuthFlows;
import io.swagger.v3.oas.models.security.SecurityRequirement;
import io.swagger.v3.oas.models.security.SecurityScheme;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.http.HttpHeaders;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurationSupport;/*** <p>Swagger 配置类</p>** @author By: chegnxuyanshitang* Package com.demo2.config* Ceate Time 2024-04-22 10:25*/
@Configuration

}
