這篇文章主要介紹了java調(diào)用webservice接口,并解析返回參數(shù)問題,具有很好的參考價(jià)值,希望對大家有所幫助,如有錯(cuò)誤或未考慮完全的地方,望不吝賜教

java調(diào)用webservice接口,并解析返回參數(shù)

1. 設(shè)置傳參

例如以下格式：

// 確定傳參格式以及賦值
String reqXml = "<createAppParam>\n" +
                    "<serviceUserName>auth</serviceUserName>\n" +
                    "<servicePwd>auth</servicePwd>\n" +
                    "<rootTicket>"+rootTicket+"</rootTicket>\n" +
                    "<appAccount>"+userAccount+"</appAccount>\n" +
                    "<resNum>1000</resNum>\n" +
                    "<operationCode>"+operationCode+"</operationCode>\n" +
                    "<functionCode>668801</functionCode>\n" +
                    "<authMode>"+mode+"</authMode>\n" +
                    "<applyReason>"+sendApplyParam.getCerReason()+"</applyReason>\n" +
                    "<userTimes>9999</userTimes>\n" +
                    "<duration>"+sendApplyParam.getExpire()+"</duration>\n" +
                    "<userIP>"+ip+"</userIP>\n" +
                    "<selectedApprover>"+sendApplyParam.getApproverId()+"</selectedApprover>\n" +
                    "<workOrderID>999999</workOrderID>\n" +
                    "<workOrderType>9999</workOrderType>\n" +
                    "</createAppParam>\n";

2. 調(diào)用對端接口

//方法調(diào)用   
//reqXml 傳入的參數(shù)信息
//applyInfoUrl 對端接口的請求地址
//type 對端接口的方法名,如果只是調(diào)用一個(gè)方法名可以寫死
String result = DocumentTrans.send(reqXml,applyInfoUrl,type);

調(diào)用實(shí)現(xiàn)代碼

 //調(diào)用接口
    public static String send(String params,String url,String type) {
        log.info("===傳遞的參數(shù)==="+params);
        log.info("===請求路徑==="+url);
        String result="";
        org.apache.axis.client.Service service = new org.apache.axis.client.Service();
        Call call = null;
        try {
            call = service.createCall();
        } catch (ServiceException e) {
            e.printStackTrace();
        }
        //10.174.242.24:7001
        call.setTargetEndpointAddress(url);
        //3、設(shè)置參數(shù)   in0(對端的方法中的參數(shù)名)
        call.addParameter("in0",
                org.apache.axis.encoding.XMLType.XSD_STRING, //參數(shù)類型
                javax.xml.rpc.ParameterMode.IN);// 接口的參數(shù)
        // 設(shè)置返回類型
        call.setReturnType(org.apache.axis.encoding.XMLType.XSD_STRING);
        try {
            result = (String) call.invoke(QName.valueOf(type), new Object[]{params});
        } catch (Exception e) {
            e.printStackTrace();
            throw new NrmsYnException("接口異常");
        }
        return result;
    }

2.解析返回的參數(shù)

轉(zhuǎn)為List<Map<String, String>>

  //2.1 先調(diào)用解析
    public static Document DocumentHelperreadStringXml(String xmlContent) {
        // DocumentHelper 解析xml字符串
        Document document = null;
        try {
            document = DocumentHelper.parseText(xmlContent);
        } catch (DocumentException e1) {
            e1.printStackTrace();
        }
        return document;
    }

    //2.2 轉(zhuǎn)換 將解析出來的數(shù)據(jù)document 傳入轉(zhuǎn)換接口Documentanalysis1  
    public static List<Map<String, String>> Documentanalysis1(Document doc) {
        List<Map<String, String>> uploadList = new ArrayList<Map<String, String>>();
        Element html = doc.getRootElement();// 獲取根結(jié)點(diǎn)
        List<Element> head = html.elements();
        Set<String> set = new HashSet<>();
        head.forEach(a -> {
            set.add(a.getName());
        });

        set.forEach(a -> {
            List<Element> elements = html.elements(a);// 獲取子結(jié)點(diǎn)
            elements.forEach(b -> {
                Map<String, String> uploadMap = new HashMap<>();
                uploadMap.put(b.getName(), b.getText());
                uploadList.add(uploadMap);
            });
        });
        //返回List<Map<String, String>>
        return uploadList;
    }
