springBoot集成RPC

需求 : 项目开发到尾期,仓库系统需要对接我们这边的制造系统,

为的是制造系统所使用物料时,需向仓库系统发送请求物料信息,所以需要调用

仓库接口.

使用技术: RPC

数据传输格式: json

开发环境:springboot

1.如何向仓库发送数据?

注意:发送的数据格式为json  例如 [{"sex":"nan","name":"1111"}] 对象外面需要 [] 直接上代码

这里转换json 其实有很多种方法 只要是 [{}]  array格式即可

1.1发送数据

 @Test
    void contexts() throws Throwable {

        Product product = new Product();
        product.setName("1111");
        product.setSex("nan");
        JSONArray jsonArray = new JSONArray();
        jsonArray.add(JSONUtil.parse(product));
        RpcClientUtil.postJsonRPC("http://127.0.0.1:8888/acceptSigned", jsonArray,"acceptSigned");
    }

1.2 RpcClientUtil.java  工具类方便发送数据自定义封装即可

import com.googlecode.jsonrpc4j.JsonRpcHttpClient;
import java.net.URL;

/**
 * address:要送数据到哪个地址
 * params : json数据
 * methodName: 接口的方法名字
 */
public class RpcClientUtil {
    public static String postJsonRPC(String address, Object params, String methodName) throws Throwable {
        URL url = null;
        JsonRpcHttpClient jsonRpcHttpClient = null;
        String result = null;
        try {
            url = new URL(address);
            jsonRpcHttpClient = new JsonRpcHttpClient(url);
            result = jsonRpcHttpClient.invoke(methodName, params, String.class);
        } catch (Exception e) {
            throw e;
        }  finally {
            url = null;
            jsonRpcHttpClient = null;
        }
        return result;
    }

}

2.仓库如何接收数据?

需要编写接口 @JsonRpcService(value = "acceptSigned")   acceptSigned 远程地址拼接用的

例如 http://127.0.0.1:8888/acceptSigned

2.1接口AcceptSignedAPI.java

package com.example.rpctest.service;

import com.googlecode.jsonrpc4j.JsonRpcService;

@JsonRpcService(value = "acceptSigned")
public interface AcceptSignedAPI {
    public void acceptSigned(Object o);
}

2.2 接口实现类 注意使用 @AutoJsonRpcServiceImpl   方法名为 acceptSigned

package com.example.rpctest.service.impl;

import com.example.rpctest.service.AcceptSignedAPI;
import com.googlecode.jsonrpc4j.spring.AutoJsonRpcServiceImpl;
import org.springframework.stereotype.Service;

@Service
@AutoJsonRpcServiceImpl
public class AcceptSignedImpl implements AcceptSignedAPI {

    @Override
    public void acceptSigned(Object o) {
        System.out.println("222"+o);
    }
}
