话不多说,直接上图
接口返回内容,浏览器显示PDF文档。但是输入接口地址以后一直提示这个
核对接口路径也是正确的,并且没有报错提示,后面发现是网关没有配置放行路径,于是进行了补充
所以 以后对于前端请求统一由网关进行配置处理的,一定要对于静态资源合理配置,或者对于放行接口要统一补充进来(最后统一一下下接口前缀名称,这样就只需要写一个了)
下面我再说一个坑:
spring cloud gateway启动报错:org.springframework.cloud.gateway.config.GatewayAutoConfiguration
springcloud 启动一直报错 详细错误信息
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.
解决办法
将pom文件中的spring-boot-starter-web 移除
详细分析
点进去 GatewayAutoConfiguration 这个类
@Bean public ModifyRequestBodyGatewayFilterFactory modifyRequestBodyGatewayFilterFactory(ServerCodecConfigurer codecConfigurer) { return new ModifyRequestBodyGatewayFilterFactory(codecConfigurer.getReaders()); } @Bean public DedupeResponseHeaderGatewayFilterFactory dedupeResponseHeaderGatewayFilterFactory() { return new DedupeResponseHeaderGatewayFilterFactory(); } @Bean public ModifyResponseBodyGatewayFilterFactory modifyResponseBodyGatewayFilterFactory(ServerCodecConfigurer codecConfigurer, Set<MessageBodyDecoder> bodyDecoders, Set<MessageBodyEncoder> bodyEncoders) { return new ModifyResponseBodyGatewayFilterFactory(codecConfigurer.getReaders(), bodyDecoders, bodyEncoders); }
确实需要这个bean
spring cloud gateway server项目是一个spring boot项目,在启动的时候会去加载它的配置,其中有一个叫做GatewayClassPathWarningAutoConfiguration的配置类 代码入下
@Configuration( proxyBeanMethods = false ) //在 GatewayAutoConfiguration 执行执行 @AutoConfigureBefore({GatewayAutoConfiguration.class}) public class GatewayClassPathWarningAutoConfiguration { private static final Log log = LogFactory.getLog(GatewayClassPathWarningAutoConfiguration.class); private static final String BORDER = " ********************************************************** "; public GatewayClassPathWarningAutoConfiguration() { } @Configuration( proxyBeanMethods = false ) @ConditionalOnMissingClass({"org.springframework.web.reactive.DispatcherHandler"}) protected static class WebfluxMissingFromClasspathConfiguration { public WebfluxMissingFromClasspathConfiguration() { GatewayClassPathWarningAutoConfiguration.log.warn(" ********************************************************** Spring Webflux is missing from the classpath, which is required for Spring Cloud Gateway at this time. Please add spring-boot-starter-webflux dependency. ********************************************************** "); } } @Configuration( proxyBeanMethods = false ) @ConditionalOnClass( name = {"org.springframework.web.servlet.DispatcherServlet"} ) protected static class SpringMvcFoundOnClasspathConfiguration { public SpringMvcFoundOnClasspathConfiguration() { GatewayClassPathWarningAutoConfiguration.log.warn(" ********************************************************** Spring MVC found on classpath, which is incompatible with Spring Cloud Gateway at this time. Please remove spring-boot-starter-web dependency. ********************************************************** "); } } }
我们pom中依赖了spring-boot-starter-web 也就是存在
org.springframework.web.servlet.DispatcherServlet
此时这个 与Spring Cloud Gateway不兼容
spring cloud gateway是基于webflux的,如果需要web支持的话需要导入spring-boot-starter-webflux取代spring-boot-start-web。
以上为个人经验,希望能给大家一个参考,也希望大家多多支持服务器之家。
