Motan快速开始

本文档演示如何将Motan服务接入到Apache ShenYu网关。您可以直接在工程下找到本文档的示例代码。

环境准备#

请参考运维部署的内容，选择一种方式启动shenyu-admin。比如，通过本地部署启动Apache ShenYu后台管理系统。

启动成功后，需要在基础配置->插件管理中，把motan 插件设置为开启。

启动网关，如果是通过源码的方式，直接运行shenyu-bootstrap中的ShenyuBootstrapApplication。

注意，在启动前，请确保网关已经引入相关依赖。本地已经成功启动zookeeper。

引入网关对Motan的代理插件，在网关的 pom.xml 文件中增加如下依赖：

        <!-- apache shenyu motan plugin -->        <dependency>            <groupId>org.apache.shenyu</groupId>            <artifactId>shenyu-spring-boot-starter-plugin-motan</artifactId>            <version>${project.version}</version>        </dependency>
        <dependency>            <groupId>com.weibo</groupId>            <artifactId>motan-core</artifactId>            <version>1.1.9</version>        </dependency>
        <dependency>            <groupId>com.weibo</groupId>            <artifactId>motan-registry-zookeeper</artifactId>            <version>1.1.9</version>        </dependency>
        <dependency>            <groupId>com.weibo</groupId>            <artifactId>motan-transport-netty4</artifactId>            <version>1.1.9</version>        </dependency>
        <dependency>            <groupId>com.weibo</groupId>            <artifactId>motan-springsupport</artifactId>            <version>1.1.9</version>        </dependency>

运行shenyu-examples-motan项目#

下载 shenyu-examples-motan 。

运行org.apache.shenyu.examples.motan.service.TestMotanApplicationmain方法启动项目。

成功启动会有如下日志：

测试Http请求#

shenyu-examples-motan项目成功启动之后会自动把加 @ShenyuMotanClient 注解的接口方法注册到网关，并添加选择器和规则，如果没有，可以手动添加。

打开插件列表 -> rpc proxy -> motan可以看到插件规则配置列表：

下面使用postman模拟http的方式来请求你的motan服务：
