報(bào)錯代碼如上：

微服務(wù)架構(gòu)

gateway和swagger沖突：

注意：我這里service-gateway并沒有使用swagger，而是使用工具類工程導(dǎo)入時(shí)帶入

如果想看gateway整合swagger，可跳過文章

。。之前本來沒有報(bào)錯，隔天啟動就報(bào)錯。。。一天多了才解決，各種方案均試過，然后又會出各種報(bào)錯，bug制造機(jī)

gateway和以下的包都沖突：

所以如果導(dǎo)入了web的jar包，需要注釋掉

gateway使用的是webflux,和web會造成沖突

   ????????<dependency>
          <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
          <scope>provided</scope>
        </dependency>

網(wǎng)關(guān)和@EnableSwagger2會沖突，如果你去掉這個注解就不會報(bào)錯，但是，會導(dǎo)致其他模塊引入的swagger測試失效：

?

?解決方案：

查看網(wǎng)關(guān)的maven依賴樹

，查找swagger出現(xiàn)的依賴工程 ，我這里已經(jīng)去掉了該工程

?

去掉有swagger依賴的工程，但是不明白為什么之前沒報(bào)錯，突然就報(bào)錯了，跟著視頻里面的老師寫的，是這樣寫的也沒報(bào)錯?

明明主啟動類沒有使用@ComponentScan來掃描swagger的包，但是swagger卻生效

待研究，，
