完整的webservice接口调用过程
作者：互联网
查看调用方法
调用地址：http://localhost:8080/WP_FOTON_FSOA/APP_FACTOR_SERVICES/Proxy_Services/TA_SAP/FACTOR_SYC_238_SendEarnestMoneyInfo_PS?wsdl
根据接口的wsdl文档可以看到调用的接口方法（FACTOR_SYC_238_SendEarnestMoneyInfoService）以及反馈参数（getFACTOR_SYC_238_SendEarnestMoneyInfoResponse）里的SIGN，MESSAGE。
查看调用格式
可以用解析webservice的框架解析也可以使用外部工具，如SoapUI解析，如下（SoapUI示例）；通过SoapUI即可查看调用接口的SOAP格式
调用接口
调用接口可通过wsimport编译，将接口的wsdl编译成本地实体类，然后调用实体类的方法即可，下面演示使用Post直接请求的方式。
一、post请求方法
1 package com.lwl.util;
2
3 import sun.misc.BASE64Encoder;
4
5 import java.io.*;
6 import java.net.HttpURLConnection;
7 import java.net.URL;
8 import java.net.URLConnection;
9 import java.nio.charset.StandardCharsets;
10
11 /**
12 * post请求
13 *
14 * @author liuwenlong
15 * @create 2021-12-04 12:25:00
16 */
17 @SuppressWarnings("all")
18 public class SendPost {
19
20 /**
21 * Post请求一个地址
22 *
23 * @param URL 请求地址
24 * @param requestBody 请求的body
25 * @param Authorization 账号密码
26 * @return 返回调用结果
27 */
28 public String doPost(String URL, String requestBody,String Authorization) {
29 OutputStreamWriter out = null;
30 BufferedReader in = null;
31 StringBuilder result = new StringBuilder();
32 HttpURLConnection conn = null;
33
34 try {
35 java.net.URL url = new URL(URL);
36 conn = (HttpURLConnection) url.openConnection();
37 BASE64Encoder base = new BASE64Encoder();
38 String encodedPassword = base.encode(Authorization.getBytes("UTF-8"));
39 //System.out.println("加密后的密码：" + encodedPassword);
40 //将加密的账号密码放到请求头里，这里注意Basic后面要加空格
41 conn.setRequestProperty("Authorization", "Basic " + encodedPassword);
42 conn.setRequestMethod("POST");
43 //发送POST请求必须设置为true
44 conn.setDoOutput(true);
45 conn.setDoInput(true);
46 //设置连接超时时间和读取超时时间
47 conn.setConnectTimeout(3000);
48 conn.setReadTimeout(3000);
49 conn.setRequestProperty("Content-Type","text/xml;charset=UTF-8");
50 //conn.setRequestProperty("Accept", "application/json");
51 //获取输出流，写入请求的json或者xml报文
52 out = new OutputStreamWriter(conn.getOutputStream(),"utf-8");
53 //System.out.println(requestBody);
54
55 out.write(requestBody); //获取请求的body,
56 out.flush();
57 out.close();
58 //取得输入流，并使用Reader读取
59 if (200 == conn.getResponseCode()) {
60 in = new BufferedReader(new InputStreamReader(conn.getInputStream(), StandardCharsets.UTF_8));
61 String line;
62 while ((line = in.readLine()) != null) {
63 result.append(line);
64 //System.out.println(line);
65 }
66 } else {
67 System.out.println("ResponseCode is an error code:" + conn.getResponseCode());
68 }
69 } catch (Exception e) {
70 e.printStackTrace();
71 } finally {
72 try {
73 if (out != null) {
74 out.close();
75 }
76 if (in != null) {
77 in.close();
78 }
79 } catch (IOException ioe) {
80 ioe.printStackTrace();
81 }
82 }
83 return result.toString();
84 }
85
86 }
二、组装报文，调用方法
1 package com.restful.client.config.FFS;
2
3 import com.lwl.util.SendPost;
4 import org.dom4j.Document;
5 import org.dom4j.DocumentException;
6 import org.dom4j.DocumentHelper;
7 import org.dom4j.Element;
8
9 /**
10 * @author liuwenlong
11 * @create 2021-12-04 12:25:31
12 */
13 @SuppressWarnings("all")
14 public class SYC_238 {
15 public static void main(String[] args) {
16 //请求地址
17 String test_URL_SYC_238 = "http://localhost:8080/WP_FOTON_FSOA/APP_FACTOR_SERVICES/Proxy_Services/TA_SAP/FACTOR_SYC_238_SendEarnestMoneyInfo_PS?wsdl";
18
19 SendPost sendPost = new SendPost();
20 String username = "admin"; //账号
21 String password = "admin111"; //密码
22 String Authorization = username + ":" + password;
23
24 String sendMessage = "请求报文放这里";
25
26 String requestBody = "<soapenv:Envelope xmlns:soapenv=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:fac=\"http://www.***.com.cn/FACTOR_SYC_238_SendEarnestMoneyInfo\">\n" +
27 " <soapenv:Header/>\n" +
28 " <soapenv:Body>\n" +
29 " <fac:FACTOR_SYC_238_SendEarnestMoneyInfoService>\n" +
30 " <fac:DATA><![CDATA[" + sendMessage + "]]></fac:DATA>\n" +
31 " </fac:FACTOR_SYC_238_SendEarnestMoneyInfoService>\n" +
32 " </soapenv:Body>\n" +
33 "</soapenv:Envelope>";
34 System.out.println("requestBody\n" + requestBody);
35 String responseBody = sendPost.doPost(test_URL_SYC_238, requestBody, Authorization);
36 System.out.println("responseBody:\n" + responseBody);
37
38 }
39 }
三、获取反馈，获取反馈可以直接根据wsdl里getFACTOR_SYC_238_SendEarnestMoneyInfoResponse方法，并取出WSDL文档里描述的SIGN，MESSAGE；
1 Document doc = null;
2 try {
3 doc = DocumentHelper.parseText(responseBody.trim());
4 } catch (
5 DocumentException e) {
6 e.printStackTrace();
7 }
8 Element root = doc.getRootElement();// 指向根节点
9 String message = root.element("Body").element("getFACTOR_SYC_238_SendEarnestMoneyInfoResponse").elementTextTrim("MESSAGE").trim();
10 String sign = root.element("Body").element("getFACTOR_SYC_238_SendEarnestMoneyInfoResponse").elementTextTrim("SIGN").trim();
11
12 System.out.println("\n反馈报文:" + message);
13 System.out.println("标识:" + sign);
14 String result = "";
15 if ("0".equals(sign)) {
16 result = "调用成功！";
17 } else {
18 result = "调用失败！";
19 }
20 System.out.println(result);
