在我引入SpringCloud-gateway,运行时报错如下:
org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'routeDefinitionRouteLocator' defined in class path resource [org/springframework/cloud/gateway/config/GatewayAutoConfiguration.class]: Unsatisfied dependency expressed through method 'routeDefinitionRouteLocator' parameter 4; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'org.springframework.core.convert.ConversionService' available: expected at least 1 bean which qualifies as autowire candidate.

从报错的信息中我们可以看到,说没有唯一的web模块,因此会造成冲突。
因为引入了spring-cloud-starter-gateway 和 spring-boot-starter-web,两者造成了冲突
只有在引入依赖的时候,去除掉一个web模块即可
<dependency> <!--引入公共模块--> <groupId>com.josh.joshmall</groupId> <artifactId>joshmall-common</artifactId> <version>0.0.1-SNAPSHOT</version> <!--排除gateway中引入的公共模块web--> <exclusions> <exclusion> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </exclusion> </exclusions> </dependency>
再次运行Spirng-cloud-gateway就成功了。
添加了路由规则的配置以后,SpringCloud无法正常启动,启动的时候报错
错误信息显示缺少javax.validation.ValidatorException类;
不能为空,之前是配置在yml文件中,后来换成了properties,问题就解决了!
