一、控制臺的報錯信息

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、解決辦法有兩種任選其一

1.方法一：配置 WebMvcConfigurer.java

package com.clesun.brandarchive.config;import org.springframework.context.annotation.Configuration; import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry; import org.springframework.web.servlet.config.annotation.WebMvcConfigurationSupport;/*** 解決高版本springboot整合swagger啟動報錯Failed to start bean 'documentationPluginsBootstrapper' 問題* @author Administrator*/ @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* @param registry*/@Overridepublic 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.方法二：yml文件里進行配置

spring:mvc:pathmatch:matching-strategy: ant_path_matcher

3.啟動

然后在頁面就可以看到swagger
