在使用springcloud -gateway的时候一定要注意

org.springframework.beans.factory.BeanCreationException: Error creating bean with name ‘configurationPropertiesBeans’ defined in class path resource
Caused by: java.lang.IllegalStateException: Failed to introspect Class [org.springframework.cloud.context.properties.ConfigurationPropertiesBeans] from ClassLoader [sun.misc.Launcher$AppClassLoader@18b4aac2]
Caused by: java.lang.ClassNotFoundException: org.springframework.boot.context.properties.ConfigurationBeanFactoryMetadata
Caused by: java.lang.NoClassDefFoundError: org/springframework/boot/context/properties/ConfigurationBeanFactoryMetadata

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

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-webflux</artifactId>
        <version>2.4.4</version>
    </dependency>
    pom中去掉这两个注解，会和gateway中的依赖产生冲突
    还有检查springcloud版本和springboot的版本是否对应
    也可能是boot版本要在2.2.5。RELEASE

org.springframework.beans.factory.BeanCreationException: Error creating bean with name ‘globalTransactionScanner’ defined in class path resource [com/alibaba/cloud/seata/GlobalTransactionAutoConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [io.seata.spring.annotation.GlobalTransactionScanner]: Factory method ‘globalTransactionScanner’ threw exception; nested exception is io.seata.common.exception.NotSupportYetException: not support register type: null
把seata 包排除 冲突了
