接口返回內(nèi)容，瀏覽器顯示PDF文檔。但是輸入接口地址以后一直提示這個(gè)

核對(duì)接口路徑也是正確的，并且沒(méi)有報(bào)錯(cuò)提示，后面發(fā)現(xiàn)是網(wǎng)關(guān)沒(méi)有配置放行路徑，于是進(jìn)行了補(bǔ)充

所以 以后對(duì)于前端請(qǐng)求統(tǒng)一由網(wǎng)關(guān)進(jìn)行配置處理的，一定要對(duì)于靜態(tài)資源合理配置，或者對(duì)于放行接口要統(tǒng)一補(bǔ)充進(jìn)來(lái)(最后統(tǒng)一一下下接口前綴名稱(chēng)，這樣就只需要寫(xiě)一個(gè)了)

spring cloud gateway啟動(dòng)報(bào)錯(cuò)：org.springframework.cloud.gateway.config.GatewayAutoConfiguration

springcloud 啟動(dòng)一直報(bào)錯(cuò) 詳細(xì)錯(cuò)誤信息

Parameter 0 of method modifyRequestBodyGatewayFilterFactory in org.springframework.cloud.gateway.config.GatewayAutoConfiguration required a bean of type ’org.springframework.http.codec.ServerCodecConfigurer’ that could not be found.

Action:

Consider defining a bean of type ’org.springframework.http.codec.ServerCodecConfigurer’ in your configuration.

將pom文件中的spring-boot-starter-web 移除

點(diǎn)進(jìn)去 GatewayAutoConfiguration 這個(gè)類(lèi)

@Beanpublic ModifyRequestBodyGatewayFilterFactory modifyRequestBodyGatewayFilterFactory(ServerCodecConfigurer codecConfigurer) { return new ModifyRequestBodyGatewayFilterFactory(codecConfigurer.getReaders());}@Beanpublic DedupeResponseHeaderGatewayFilterFactory dedupeResponseHeaderGatewayFilterFactory() { return new DedupeResponseHeaderGatewayFilterFactory();}@Beanpublic ModifyResponseBodyGatewayFilterFactory modifyResponseBodyGatewayFilterFactory(ServerCodecConfigurer codecConfigurer, Set<MessageBodyDecoder> bodyDecoders, Set<MessageBodyEncoder> bodyEncoders) { return new ModifyResponseBodyGatewayFilterFactory(codecConfigurer.getReaders(), bodyDecoders, bodyEncoders);}

確實(shí)需要這個(gè)bean

spring cloud gateway server項(xiàng)目是一個(gè)spring boot項(xiàng)目，在啟動(dòng)的時(shí)候會(huì)去加載它的配置，其中有一個(gè)叫做GatewayClassPathWarningAutoConfiguration的配置類(lèi) 代碼入下

@Configuration( proxyBeanMethods = false)//在 GatewayAutoConfiguration 執(zhí)行執(zhí)行 @AutoConfigureBefore({GatewayAutoConfiguration.class})public class GatewayClassPathWarningAutoConfiguration { private static final Log log = LogFactory.getLog(GatewayClassPathWarningAutoConfiguration.class); private static final String BORDER = 'nn**********************************************************nn'; public GatewayClassPathWarningAutoConfiguration() { } @Configuration(proxyBeanMethods = false ) @ConditionalOnMissingClass({'org.springframework.web.reactive.DispatcherHandler'}) protected static class WebfluxMissingFromClasspathConfiguration {public WebfluxMissingFromClasspathConfiguration() { GatewayClassPathWarningAutoConfiguration.log.warn('nn**********************************************************nnSpring Webflux is missing from the classpath, which is required for Spring Cloud Gateway at this time. Please add spring-boot-starter-webflux dependency.nn**********************************************************nn');} } @Configuration(proxyBeanMethods = false ) @ConditionalOnClass(name = {'org.springframework.web.servlet.DispatcherServlet'} ) protected static class SpringMvcFoundOnClasspathConfiguration {public SpringMvcFoundOnClasspathConfiguration() { GatewayClassPathWarningAutoConfiguration.log.warn('nn**********************************************************nnSpring MVC found on classpath, which is incompatible with Spring Cloud Gateway at this time. Please remove spring-boot-starter-web dependency.nn**********************************************************nn');} }}

我們pom中依賴(lài)了spring-boot-starter-web 也就是存在

org.springframework.web.servlet.DispatcherServlet

此時(shí)這個(gè) 與Spring Cloud Gateway不兼容

spring cloud gateway是基于webflux的，如果需要web支持的話需要導(dǎo)入spring-boot-starter-webflux取代spring-boot-start-web。

以上為個(gè)人經(jīng)驗(yàn)，希望能給大家一個(gè)參考，也希望大家多多支持好吧啦網(wǎng)。
