成功解决：java.lang.NoSuchMethodError: reactor.netty.http.client.HttpClient.chunkedTransfer(Z)Lreactor/ne-摩杜云开发者社区

前言

在微服务中整合gateway网关，网关服务成功启动、在访问地址的时候报错。主要原因是依赖父工程spring-boot-starter-parent 的版本和依赖网关spring-cloud-starter-gateway的版本不同导致。

错误信息

在这里插入代码片

在进行地址跳转的时候，没有做出相应的页面跳转。同时控制台报错

解决方法

先前的版本(错误版本)

<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.2.1.RELEASE</version>
        <relativePath/>
    </parent>

        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-gateway</artifactId>
            <version>2.1.3.RELEASE</version>
        </dependency>

提示：
这里要说明一下，如果在创建网关服务的时候勾选了gateway，生成的pom中是没有版本号的、默认应该是最新。根据控制台的信息提示，gateway的版本是2.1.3.RELEASE，如果改成其它版本也会出现类似的情况

修改后可行的版本

<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.1.3.RELEASE</version>
        <relativePath/> 
    </parent>
            <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-gateway</artifactId>
            <version>2.1.3.RELEASE</version>
        </dependency>
