通过 jackson-xml 来解析 XML 文件
最近有个项目需要解析某商户平台上面导出的账单文件，文件格式如下：
1 <?xml version="1.0" encoding="UTF-8"?> 2 <?mso-application progid="Excel.Sheet"?> 3 <Workbook xmlns="urn:schemas-microsoft-com:office:spreadsheet" xmlns:o="urn:schemas-microsoft-com:office:office" 4 xmlns:x="urn:schemas-microsoft-com:office:excel" xmlns:ss="urn:schemas-microsoft-com:office:spreadsheet" 5 xmlns:html="http://www.w3.org/TR/REC-html40"> 6 <Worksheet ss:Name="卖出交易1"> 7 <Null/> 8 <Table ss:ExpandedColumnCount="100" ss:ExpandedRowCount="1000000" ss:DefaultColumnWidth="54.0" 9 ss:DefaultRowHeight="13.5"> 10 <Null/> 11 <Row> 12 <Cell> 13 <Data ss:Type="String">#账号：asdasdasdadasd@gmail.com[XXXXXX]</Data> 14 </Cell> 15 </Row> 16 <Row> 17 <Cell> 18 <Data ss:Type="String">#查询起始日期：2018-04-10 00:00:00查询终止日期：2018-04-13 00:00:00</Data> 19 </Cell> 20 </Row> 21 <Row> 22 <Cell> 23 <Data ss:Type="String">序号</Data> 24 </Cell> 25 <Cell> 26 <Data ss:Type="String">创建时间</Data> 27 </Cell> 28 <Cell> 29 <Data ss:Type="String">商品名称</Data> 30 </Cell> 31 <Cell> 32 <Data ss:Type="String">商户订单号</Data> 33 </Cell> 34 <Cell> 35 <Data ss:Type="String">XXX交易号</Data> 36 </Cell> 37 <Cell> 38 <Data ss:Type="String">对方账户</Data> 39 </Cell> 40 <Cell> 41 <Data ss:Type="String">对方名称</Data> 42 </Cell> 43 <Cell> 44 <Data ss:Type="String">订单金额(元)</Data> 45 </Cell> 46 <Cell> 47 <Data ss:Type="String">退款金额(元)</Data> 48 </Cell> 49 <Cell> 50 <Data ss:Type="String">服务费(元)</Data> 51 </Cell> 52 <Cell> 53 <Data ss:Type="String">交易状态</Data> 54 </Cell> 55 <Cell> 56 <Data ss:Type="String">退服务费(元)</Data> 57 </Cell> 58 <Cell> 59 <Data ss:Type="String">分公司</Data> 60 </Cell> 61 <Cell> 62 <Data ss:Type="String">银行订单号</Data> 63 </Cell> 64 <Cell> 65 <Data ss:Type="String">交易分类</Data> 66 </Cell> 67 <Cell> 68 <Data ss:Type="String">交易方式</Data> 69 </Cell> 70 <Cell> 71 <Data ss:Type="String">门店</Data> 72 </Cell> 73 </Row> 74 <Row> 75 <Cell> 76 <Data ss:Type="String">1</Data> 77 </Cell> 78 <Cell> 79 <Data ss:Type="String">2012-04-12 23:40:05</Data> 80 </Cell> 81 <Cell> 82 <Data ss:Type="String">XXXX</Data> 83 </Cell> 84 <Cell> 85 <Data ss:Type="String">XXX</Data> 86 </Cell> 87 <Cell> 88 <Data ss:Type="String">XXXX</Data> 89 </Cell> 90 <Cell> 91 <Data ss:Type="String">159******90</Data> 92 </Cell> 93 <Cell> 94 <Data ss:Type="String">*黄</Data> 95 </Cell> 96 <Cell> 97 <Data ss:Type="String">58.88</Data> 98 </Cell> 99 <Cell> 100 <Data ss:Type="String">0.00</Data> 101 </Cell> 102 <Cell> 103 <Data ss:Type="String">0.12</Data> 104 </Cell> 105 <Cell> 106 <Data ss:Type="String">成功</Data> 107 </Cell> 108 <Cell> 109 <Data ss:Type="String">0.00</Data> 110 </Cell> 111 <Cell> 112 <Data ss:Type="String"></Data> 113 </Cell> 114 <Cell> 115 <Data ss:Type="String"></Data> 116 </Cell> 117 <Cell> 118 <Data ss:Type="String">外部商户</Data> 119 </Cell> 120 <Cell> 121 <Data ss:Type="String">即时到帐</Data> 122 </Cell> 123 <Cell> 124 <Data ss:Type="String"></Data> 125 </Cell> 126 </Row> 127 <Row> 128 <Cell> 129 <Data ss:Type="String">#导出时间：2018-04-13 11:07:31</Data> 130 </Cell> 131 </Row> 132 </Table> 133 </Worksheet> 134 </Workbook>
第二步，我们创建解析实体的映射类
1 @Data 2 public class XXBillExcelDto { 3 4 @JacksonXmlProperty(localName = "Worksheet") 5 private Worksheet worksheet; 6 7 @Data 8 public static class Worksheet { 9 @JacksonXmlElementWrapper(localName = "Table") 10 @JacksonXmlProperty(localName = "Row") 11 private List<Row> rows = new ArrayList<>(); 12 13 public List<Row> getRows() { 14 return rows; 15 } 16 17 public void setRows(List<Row> rows) { 18 this.rows.addAll(rows); 19 } 20 } 21 22 @Data 23 public static class Row { 24 @JacksonXmlElementWrapper(localName = "Cell") 25 @JacksonXmlProperty(localName = "Data") 26 private List<String> cells = new ArrayList<>(); 27 28 public List<String> getCells() { 29 return cells; 30 } 31 32 public void setCells(List<String> cells) { 33 this.cells.addAll(cells); 34 } 35 } 36 }
第三步，来看我们的解析方法
1 InputStream is = new FileInputStream(new File("a.xls")); 2 ObjectMapper objectMapper = new XmlMapper(); 3 4 objectMapper.configure(DeserializationFeate.FAIL_ON_UNKNOWN_PROPERTIES, false); 5 6 XXBillExcelDto dto = objectMapper.readValue(is, XXBillExcelDto.class);
