java 解析hex报文 java 解析xml报文

1、xml格式报文

String rtnMsgXML = "<?xml version=\"1.0\" encoding='UTF-8'?>\n" +
                "<DBSET RESULT=\"1\">\n" +
                "<R>\n" +
                "<C N=\"rtnMsg\">短信发送失败</C>\n" +
                "<C N=\"rtnCode\">1</C>\n" +
                "</R>\n" +
                "</DBSET>";

2、解析报文核心方法

public static Map<String, Object> getValueByNode(String xml, List<String> nodes, String charsetName) throws DocumentException, UnsupportedEncodingException {
        Document document = new SAXReader().read(new ByteArrayInputStream(xml.getBytes(charsetName)));
        Map<String, Object> result = new HashMap();
        nodes.forEach(node -> {
            String xpath = "//" + "R" + "//" + "C" + "[@N='"+node+"']";
            Node singleNode = document.selectSingleNode(xpath);
            if(singleNode != null) {
                result.put(node, singleNode.getStringValue());
            }
        });
        return result;
    }

3、调用xml报文解析方法完成解析

List<String> nodes = new ArrayList<>();
        Map<String, Object> map1 = new HashMap<>();
        nodes.add("rtnMsg");
        nodes.add("rtnCode");
        map1 = getValueByNode(rtnMsgXML, nodes, "UTF-8");

注：map1返回格式

{"rtnMsg":"短信发送失败","rtnCode":"1"}

4、最终代码

import java.util.HashMap;
import java.util.List;
import java.util.Map;
public static void main(String[] args) {
        String rtnMsgXML = "<?xml version=\"1.0\" encoding='UTF-8'?>\n" +
                "<DBSET RESULT=\"1\">\n" +
                "<R>\n" +
                "<C N=\"rtnMsg\"></C>\n" +
                "<C N=\"rtnCode\">0</C>\n" +
                "</R>\n" +
                "</DBSET>";
        List<String> nodes = new ArrayList<>();
        Map<String, Object> map1 = new HashMap<>();
        nodes.add("rtnMsg");
        nodes.add("rtnCode");
        map1 = getValueByNode(rtnMsgXML, nodes, "UTF-8");
    }
