SpringCloud：gateway网关模块启动报错

1.错误信息

2.原因

同时引入依赖：spring-cloud-starter-gateway 和 spring-boot-starter-web

在gateway中已经引用了web模块，因此会造成冲突，这个原因我之前在学习gateway时其实已经注意到了，但是依旧报错

pom.xml文件如下

<dependencies>

        <dependency>

            <groupId>com.fdzang.microservice</groupId>

            <artifactId>api-common</artifactId>

            <version>1.0-SNAPSHOT</version>

        </dependency>

        <dependency>

            <groupId>org.springframework.cloud</groupId>

            <artifactId>spring-cloud-starter-gateway</artifactId>

            <version>${spring.cloud.starter.version}</version>

        </dependency>

        <dependency>

            <groupId>org.springframework.cloud</groupId>

            <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>

            <version>${spring.cloud.starter.version}</version>

        </dependency>

        <dependency>

            <groupId>org.springframework.boot</groupId>

            <artifactId>spring-boot-configuration-processor</artifactId>

            <version>${spring.boot.version}</version>

            <optional>true</optional>

        </dependency>

    </dependencies>

在我的pom中并未依赖web模块，依旧报错，于是尝试在gateway中排除web，无果，遂百度。

经历了各种尝试之后，我发现我引用的公共模块common中引用了web模块，破案了

于是移除

<dependency>

　　<groupId>com.fdzang.microservice</groupId>

　　<artifactId>api-common</artifactId>

　　<version>1.0-SNAPSHOT</version>

　　<exclusions>

　　　　<exclusion>

　　　　　　<groupId>org.springframework.boot</groupId>

　　　　　　<artifactId>spring-boot-starter-web</artifactId>

　　　　</exclusion>

　　</exclusions>

</dependency>

运行成功。
