代码

1.组装参数

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns:context="http://www.springframework.org/schema/context"xmlns:aop="http://www.springframework.org/schema/aop"xmlns:util="http://www.springframework.org/schema/util"xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsdhttp://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.2.xsdhttp://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsdhttp://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util.xsd"><context:annotation-config/><context:component-scan base-package="lu.tool"><!--将Controller的注解排除掉 --><context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/></context:component-scan><aop:aspectj-autoproxy/>
</beans>

2.加密参数

  //对密钥进行MD5String md5 = Md5Util.getMD5(private_key);//sm4对数据加密String xmlStrSM4=new SM4().encode(xmlStr.toString(),md5 );//对接方传递公钥给我方，我方会根据对接方的公钥查询出密钥对数据解密xmlStrSM4=xmlStrSM4.replaceAll("[\\n\\r]", "");JSONObject jsonObject = getUrlBySoap( token, appKey, xmlStrSM4);

3.发起连接

    /*** 根据soap请求获取url* @param token* @param xmlStr* @return* @throws ServiceException*/public String getUrlBySoap(String token,String xmlStr) throws ServiceException {String endpoint=evaluation_url;Service service = new Service();Call call = (Call) service.createCall();SOAPHeaderElement head = new SOAPHeaderElement("http://linewell.com/ws/", "Authorization", "Basic " + token);call.addHeader(head);call.setTargetEndpointAddress(endpoint);call.setReturnType(org.apache.axis.encoding.XMLType.XSD_STRING);String result = getSaveEvaluationUrl(call,xmlStr);return result;}public String getSaveEvaluationUrl(Call c ,String xmlStr) {c.addParameter("appKey",   org.apache.axis.encoding.XMLType.XSD_STRING,  javax.xml.rpc.ParameterMode.IN);// 接口的参数 c.addParameter("xmlStr",   org.apache.axis.encoding.XMLType.XSD_STRING,  javax.xml.rpc.ParameterMode.IN);// 接口的参数 c.setOperationName("getSaveEvaluationUrl");// WSDL里面描述的接口名称   newSubmit     submitString appKey= public_key;//公钥String result = "";try{result=(String)c.invoke(new Object[] {appKey,xmlStr});}catch(Exception e){String errStr=getStackTraceInfo(e);//请记录日志//log.error("你们能标识这条记录的表示："+id+"错误信息："+errStr);System.out.println("你们能标识这条记录的表示：错误信息："+errStr);if(errStr.contains("access_token_invalid")){System.out.println("请重新获取token并重新请求接口");//token失效，请重新获取token并且重新请求接口，//同一个标识请求都报这个三次以内重新请求获取，超过3次不用再请求，找运维人员反馈就行}}return result;}

4.解析返回数据

 public JSONObject getResultUrl(String soapUrl) throws DocumentException {JSONObject result = new JSONObject();//报文转成doc对象Document doc = DocumentHelper.parseText(soapUrl);//获取根元素，准备递归解析这个XML树Element root = doc.getRootElement();//获取叶子节点的方法String leafNode = "";leafNode = getCode(root);if(leafNode != null){String resultUrl = leafNode;result.put("url",resultUrl);}return result;
}/*** 找到soap的xml报文的叶子节点的数据* @param root*/
public String getCode(Element root) throws DocumentException {String result = "";if (root.elements() != null) {//如果当前跟节点有子节点，找到子节点List<Element> list = root.elements();//遍历每个节点for (Element e : list) {if (e.elements().size() > 0) {//当前节点不为空的话，递归遍历子节点；result=getCode(e);if(result != null && result != ""){return result;}}if (e.elements().size() == 0) {String a2 =  e.getQName().getName();if(a2.equals("url")){result = e.getTextTrim();return result;}}}}else{return root.getTextTrim();}return result;
}
