使用Springcloud Gateway和Spring AI遇到的问题

1. 启动微服务时出现以下问题

Web application could not be started as there was no org.springframework.boot.web.reactive.server.ReactiveWebServerFactory bean defined in the context.

解决方法

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

2. 访问openAI的URL时请求超时

   org.springframework.web.client.ResourceAccessException: I/O error on POST request for "https://api.openai.com/v1/chat/completions": Connection timed out: connect

国内无法直接调用openAI的接口，需要使用国内代理https://api.chatanywhere.tech

spring:ai:openai:base-url: https://api.chatanywhere.tech

3. 引进alibaba ai后日志冲突

Exception in thread "main" java.lang.IllegalArgumentException: LoggerFactory is not a Logback LoggerContext but Logback is on the classpath. Either remove Logback or the competing implementation (class org.slf4j.simple.SimpleLoggerFactory loaded from file:/E:/mavenRepository/org/slf4j/slf4j-simple/2.0.13/slf4j-simple-2.0.13.jar). If you are using WebLogic you will need to add 'org.slf4j' to prefer-application-packages in WEB-INF/weblogic.xml: org.slf4j.simple.SimpleLoggerFactory

spring-cloud-starter-alibaba-ai依赖中包含了其他日志框架

<dependency><groupId>com.alibaba.cloud</groupId><artifactId>spring-cloud-starter-alibaba-ai</artifactId><exclusions><exclusion><groupId>org.slf4j</groupId><artifactId>slf4j-simple</artifactId></exclusion></exclusions>
</dependency>

不小心把依赖spring-cloud-starter-bootstrap删除导致这个问题，重新加回去就可以了

        <dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-starter-bootstrap</artifactId></dependency>

5. 网关路由404

访问/actuator/gateway/routes时出现404

虽然加了actuator依赖和management.endpoints.web.exposure.include=*，但把management.endpoint.gateway.enabled=true遗漏了
补充配置之后就正常了

management:endpoints:web:exposure:include: "*"endpoint:gateway:enabled: true

6. 通过springcloud gateway访问时出现503

 There was an unexpected error (type=Service Unavailable, status=503).

原因是遗漏了负载均衡，添加依赖就OK了

        <dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-starter-loadbalancer</artifactId></dependency>
