SpringCloud Alibaba Gateway 启动报错

***************************
APPLICATION FAILED TO START
***************************

Description:

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.

原因：

要排除其他依赖的spring-boot-starter-web,因为会与spring cloud gateway的webflux冲突。

解决方案1：

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

修改成

<dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-gateway</artifactId>
            <exclusions>
                <exclusion>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-starter-web</artifactId>
                </exclusion>
                <exclusion>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-starter-webflux</artifactId>
                </exclusion>
            </exclusions>
        </dependency>

我按照这种方法启动成功了。

解决方案2：

        <!-- 核心模块,因为我的核心模块引入了spring-boot-starter-web，将其排除  -->
        <dependency>
            <groupId>huluwa</groupId>
            <artifactId>boss-xtrain-core</artifactId>
            <version>${huluwa.version}</version>
            <exclusions>
                <exclusion>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-starter-web</artifactId>
                </exclusion>
            </exclusions>
        </dependency>
        
        <!--新增gateway,要排除其他依赖的spring-boot-starter-web,因为会与gateway的webflux冲突
        不排除依赖报Consider defining a bean of type 'org.springframework.http.codec.ServerCodecConfigurer' in your configuration.-->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-gateway</artifactId>
        </dependency>
