使用axis2

public static final String URL = "http://fy.webxml.com.cn/webservices/EnglishChinese.asmx";
	public String englishToChinese(String word) {
		try {
			EnglishChineseStub stub = new EnglishChineseStub(URL);
			EnglishChineseStub.TranslatorString translator = new EnglishChineseStub.TranslatorString
 
();
			translator.setWordKey(word);
			TranslatorStringResponse translatorString = stub.translatorString(translator);
			ArrayOfString stringResult = translatorString.getTranslatorStringResult();
			String[] strings = stringResult.getString();
			Arrays.asList(strings).forEach(t->System.out.println
 
(t));
		} catch (AxisFault e) {
			e.printStackTrace();
		}catch(Exception e) {
			e.printStackTrace();
		}
		return null;
	}

使用httpclient

• 引入jar檔案
  開發客戶單程式碼

public class HttpclientForWebService {
    private static final Logger LOGGER = LoggerFactory.getLogger(HttpclientForWebService.class);
    private
 
 static final String UTF_8 = "utf-8";
    private static final String CONTENT_TYPE = "text/xml; charset=utf-8";
    public static final String SUCCESS = "success";
    public static final String MSG = "msg";
    public static final String RESULTCODE = "resultCode";
    private String methodName;
    private String wsdlLocation;
	public HttpclientForWebService() {
		super();
	}
	public HttpclientForWebService(String wsdlLocation) {
        this.wsdlLocation = wsdlLocation;
    }
    public HttpclientForWebService(String methodName, String wsdlLocation) {
        this.methodName = methodName;
        this.wsdlLocation = wsdlLocation;
    }

    // 執行請求方法
    public Map<String, Object> invoke(Map<String, String> patameterMap) {
        PostMethod postMethod = new PostMethod(wsdlLocation);
        String soapRequestData = buildRequestData(patameterMap);
        LOGGER.info("請求報文資料：wsdlLocation:{},data:{}", wsdlLocation, soapRequestData);
        Map<String, Object> result = new HashMap<>();
        try {
            byte[] bytes = soapRequestData.getBytes(UTF_8);
            InputStream inputStream = new ByteArrayInputStream(bytes, 0, bytes.length);
            RequestEntity requestEntity = new InputStreamRequestEntity(inputStream, bytes.length,
                    CONTENT_TYPE);
            postMethod.setRequestEntity(requestEntity);

            HttpClient httpClient = new HttpClient();
            int statusCode = httpClient.executeMethod(postMethod);

            if (statusCode == 200) {
                String soapResponseData = postMethod.getResponseBodyAsString();
                result.put(RESULTCODE, soapResponseData);
                result.put(SUCCESS, true);
                return result;

            } else {
                LOGGER.info("soapRequestData 呼叫失敗！錯誤碼：{}", statusCode);
            }
            result.put(MSG, "Call fails" + statusCode);
            result.put(SUCCESS, false);
        } catch (UnsupportedEncodingException e) {
            result.put(MSG, "UnsupportedEncodingException");
            result.put(SUCCESS, false);
            LOGGER.error(e.getMessage());
        } catch (HttpException e) {
            result.put(MSG, "Http Request Exception");
            result.put(SUCCESS, false);
            LOGGER.error(e.getMessage());
        } catch(ConnectException e) {
        	result.put(MSG, "Connection refused");
            result.put(SUCCESS, false);
            LOGGER.error(e.getMessage());
        }catch (Exception e) {
            result.put(MSG, "Systematic analytic anomaly");
            result.put(SUCCESS, false);
            LOGGER.error(e.getMessage());
        }
        return result;
    }

    // 封裝請求的body資料,每一個wsdl都不一樣，可以使用soapui檢視
    private String buildRequestData(Map<String, String> patameterMap) {
        StringBuilder soapRequestData = new StringBuilder();
        soapRequestData.append("<?xml version=\"1.0\" encoding=\"utf-8\"?>");
        soapRequestData.append(
                "<soapenv:Envelope xmlns:soapenv=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:web=\"http://WebXml.com.cn/\">")
                .append("<soapenv:Header/>").append("<soapenv:Body>").append("<web:TranslatorString>");
        Set<String> nameSet = patameterMap.keySet();
        //可能會有多個引數
        for (String name : nameSet) {
            soapRequestData.append("<" + name + ">" + patameterMap.get(name) + "</" + name + ">");
        }
        soapRequestData.append("</web:TranslatorString>");
        soapRequestData.append("</soapenv:Body>");
        soapRequestData.append("</soapenv:Envelope>");
        return soapRequestData.toString();
    }
}

使用hutool工具

• 引入開源工具類
  開發客戶端程式碼

/**
 * @author xpy
 * hutool地址：http://hutool.mydoc.io/undefined#category_76217
 */
public class EnglishChineseClient {
	public String englishChinese(String word,String url) {
		String body = HttpRequest.post(url)
		.header("Content-Type", "application/x-www-form-urlencoded")
		.form("wordKey", word)
		.timeout(2000)
		.execute().body();
		return body;
	}

}

使用feign

• 引入jar包

public class FeignApi {
	public String englishChinese(String word) {
		RemoteService service = Feign.builder()
				.encoder((o,type,template)->{
					JSONObject json = JSONUtil.parseObj(o);
					String data = buildRequestData(json);
					template.body(data);
				})
				.decoder((response,type)->{
					Decoder.Default d = new Decoder.Default();
					return d.decode(response, type);
				})
				.target(RemoteService.class,"http://fy.webxml.com.cn");
		
		return service.getChinese(word);
	}
	private String buildRequestData(JSONObject json) {
        StringBuilder soapRequestData = new StringBuilder();
        soapRequestData.append("<?xml version=\"1.0\" encoding=\"utf-8\"?>");
        soapRequestData.append(
                "<soapenv:Envelope xmlns:soapenv=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:web=\"http://WebXml.com.cn/\">")
                .append("<soapenv:Header/>").append("<soapenv:Body>").append("<web:TranslatorString>");
        Set<String> nameSet = json.keySet();
        //可能會有多個引數
        for (String name : nameSet) {
            soapRequestData.append("<" + name + ">" + json.get(name) + "</" + name + ">");
        }
        soapRequestData.append("</web:TranslatorString>");
        soapRequestData.append("</soapenv:Body>");
        soapRequestData.append("</soapenv:Envelope>");
        return soapRequestData.toString();
    }
}

介面

public interface RemoteService {
	@RequestLine("POST /app/know/xxx")
	@Headers("Content-Type: application/json")
	String getCust(String params);
	
	@RequestLine("POST /webservices/EnglishChinese.asmx")
	@Headers("Content-Type: text/xml")
	String getChinese(@Param(value = "web:wordKey") String wordKey);
}

總結：使用axis2生成的程式碼，冗餘量大，當測試環境的action和現網的action不一樣時，導致出錯
