instructions

The gateway can support calling Java Dubbo cluster and golang Dubbo cluster

You can use ‘go build’ and ‘./start.sh’ to start gateway. then,you can do http request to you dubbo interface.

HTTP request format when do not have metadata center:

Group and version is the mapping data in Dubbo service.

{application Name}/{Interface name}?version={version}&group={group}&method={method}

http POST body:

{
    "paramTypes" : ["org.apache.dubbo.demo.model.User"],
    "paramValues": [
        {
            "id": 23,
            "username": "testUser"
        }
    ]
}

HTTP request format when have metadata center:

{application Name}/{Interface name}?version={version}&group={group}&method={method}

{
    "paramValues": [
        {
            "id": 23,
            "username": "testUser"
        }
    ]
}

服务端配置元数据中心：

添加依赖

<dependency>
    <groupId>org.apache.dubbo</groupId>
    <artifactId>dubbo-metadata-report-redis</artifactId>
</dependency>

在provider和consumer应用中配置MetadataReportConfig

@Bean
public MetadataReportConfig metadataReportConfig() {
    MetadataReportConfig metadataReportConfig = new MetadataReportConfig();
    metadataReportConfig.setAddress("redis://localhost:6379");
    return metadataReportConfig;
}

启动provider，可以在redis中发现多了一个key

org.apache.dubbo.demo.DemoService:provider:dubbo-demo-annotation-provider.metaData
{
    "parameters": {
        "side": "provider",
        "release": "",
        "methods": "sayHello",

    },

            ],

        }
    ],
    "types": [
        {
            "type": "byte"
        },
        {

            "properties": {
                "coder": {
                    "type": "byte"
                },

                }
            }

        {
            "type": "int"
        }
    ]
