java調用接口之webService方式

一.webservice調用類

package com.tbl.common.utils;

import com.alibaba.fastjson.JSON;
import com.alibaba.fastjson.JSONObject;
import com.tbl.common.config.StaticConfig;
import org.apache.cxf.endpoint.Client;
import org.apache.cxf.endpoint.dynamic.DynamicClientFactory;
import org.apache.cxf.transport.http.HTTPConduit;
import org.apache.cxf.transports.http.configuration.HTTPClientPolicy;

import java.util.Map;

/**
 * webservice工具類
 */
public class WebServiceUtil {

    private static Client client;
    private static Object lock = new Object();

    /**
     * 調取webService服務
     * @return
     */
    public static Client getClient(String path){
        if(client == null){
            synchronized (lock) {
                if(client == null){
                    DynamicClientFactory dcf = DynamicClientFactory.newInstance();
                    //獲取ReadRfid接口
                    client = dcf.createClient(path);
                    HTTPConduit http = (HTTPConduit) client.getConduit();
                    HTTPClientPolicy httpClientPolicy = new HTTPClientPolicy();
                    httpClientPolicy.setConnectionTimeout(1000 * 60 * 10);
                    httpClientPolicy.setAllowChunking(false);
                    httpClientPolicy.setReceiveTimeout(1000 * 60 * 100);
                    http.setClient(httpClientPolicy);
                }
            }
        }
        return client;
    }

    public static void readRfid(String[] args) throws Exception {
        Client client = getClient("http://localhost:8080/ReadRfid.asmx?wsdl");
        Object[] response = client.invoke("readRfid");
        JSONObject json = JSONObject.parseObject(response[0].toString());
        if(json.getBoolean("Result")){
            String rfid = json.getString("Rfid");
        }
        System.out.println("調用結果 is " + response[0]);
    }
}

2.調用示例

 

@RequestMapping(value = "/readRfid")
    @ResponseBody
    public Map<String, Object> readRfid(HttpServletRequest request) {
        Map<String, Object> map = new HashMap<>();
        boolean flag = false;
        String msg = "掃描失敗";
        String rfid = "";
        try {
            String ip = IPUtils.getIpAddr(request);
            Client client = WebServiceUtil.getClient(StaticConfig.getReadRfidURL().replace("ip", ip));
            Object[] response = client.invoke("readRfid");
            JSONObject json = JSONObject.parseObject(response[0].toString());
//            client.close();
            flag = json.getBoolean("Result");
            msg = json.getString("Msg");
            rfid = json.getString("Rfid");
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            interfaceLogService.interfaceLogInsert("掃描讀取RFID接口", "", msg, DateUtils.getTime());
        }
        map.put("code", flag ? PgConst.AJAX_TRUE : PgConst.AJAX_FALSE);
        map.put("msg", msg);
        map.put("rfidCode", rfid);

        try {
            Thread.sleep(100L);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }

        return map;
    }
