解決 高版本SpringBoot整合Swagger 啓動報錯Failed to start bean ‘documentationPluginsBootstrapper‘ 問題

一、控制檯報錯信息

2021-12-29 15:15:04 [main] ERROR org.springframework.boot.SpringApplication - Application run failed
org.springframework.context.ApplicationContextException: Failed to start bean 'documentationPluginsBootstrapper'; nested exception is java.lang.NullPointerException

二、兩種解決辦法

import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurationSupport;
 
/**
 * @author Andon
 * 2021/12/29
 */
@Configuration
public class WebMvcConfigurer extends WebMvcConfigurationSupport {
 
    /**
     * 發現如果繼承了WebMvcConfigurationSupport，則在yml中配置的相關內容會失效。 需要重新指定靜態資源
     */
    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/**").addResourceLocations(
                "classpath:/static/");
        registry.addResourceHandler("swagger-ui.html", "doc.html").addResourceLocations(
                "classpath:/META-INF/resources/");
        registry.addResourceHandler("/webjars/**").addResourceLocations(
                "classpath:/META-INF/resources/webjars/");
        super.addResourceHandlers(registry);
    }
 
}

2、配置文件添加spring.mvc.pathmatch.matching-strategy=ant_path_matcher

spring:
  mvc:
    pathmatch:
      matching-strategy: ant_path_matcher
