35 | TestBean testBean = new TestBean(); 36 | testBean.setIntTest(8888); 37 | testBean.setStrTest("88888.888"); 38 | testBean.setTimeTest(new Timestamp(System.currentTimeMillis())); 39 | for (int i = 0; i < 1000; i++) { 40 | li.add(testBean); 41 | } 42 | LinkedHashMap keyMap = new LinkedHashMap(); 43 | keyMap.put("timeTest", "time类型"); 44 | keyMap.put("intTest", "int类型"); 45 | keyMap.put("strTest", "string类型"); 46 | 47 | List sheetContentList = new ArrayList(); 48 | ExportExcelBean bean1 = new ExportExcelBean(); 49 | bean1.setContentList(li); 50 | bean1.setKeyMap(keyMap); 51 | bean1.setSheetName("测试1"); 52 | ExportExcelBean bean2 = new ExportExcelBean(); 53 | bean2.setContentList(li); 54 | bean2.setKeyMap(keyMap); 55 | bean2.setSheetName("测试2"); 56 | 57 | sheetContentList.add(bean1); 58 | sheetContentList.add(bean2); 59 | ``` 60 | 如上所示演示了将一些测试数据填入到ExportExcelBean中。ExportExcelBean有三个属性 61 | sheetname:表名。在一个excel文件中，允许存在多个表。每个表的名字，一般会在excel左下角显示，如下所示 62 | ![上传图片](http://image.game.yy.com/o/cloudapp/25586759/170x170/201506-bbc2a60f_094e_498b_87e7_2ead79ca9536.png) 63 | 64 | contentList:要填充的内容。表的每一行，是一个对象，多个对象一起，就组成了这个contentList。对象的类，可以依据你自己的实际情况，用自己写的类。本文例子中，是将数据填充到TestBean 这个类中 65 | 66 | keyMap:表列名及属性映射关系。请注意，这是一个LinkedHashMap，也就是说，是有顺序先后性的。之后你要调整每一列的顺序，也只要调整这里的顺序即可 67 | 如例子中这三行代码，表示表的第一列，列的标题为time类型，填充的值为TestBean 类中timeTest这个属性。第二列标题则为“int类型”，填充TestBean 中intTest属性 68 | ```java 69 | keyMap.put("timeTest", "time类型"); 70 | keyMap.put("intTest", "int类型"); 71 | keyMap.put("strTest", "string类型"); 72 | 73 | ``` 74 | 75 | 76 | ###3、基于注解 77 | 基于注解的方式，指的是excel的列，列名，顺序等由源数据bean中的注解来指定。测试类TestExtend演示了这个方式 78 | 79 | ```java 80 | @ExcelSheet(name = "这是表的名字", order = "strTest,intTest") 81 | public class TestBean { 82 | @SheetCol("字符串") 83 | private String strTest; 84 | @SheetCol("数字") 85 | private int intTest; 86 | @SheetCol("时间") 87 | private Timestamp timeTest; 88 | 89 | //这里省略get、set方法 90 | ｝ 91 | 92 | ``` 93 | 94 | 这里假设我们要将List的数据输出为excel，可以像上面这样做注解。 95 | - 注解ExcelSheet，name属性指定了表的名字，order属性指定了列的顺序，其中的值是bean中的属性名，多个属性用逗号隔开 96 | - 注解SheetCol,带有这个注解的属性，才会被输出到excel中，且表头的列名，为这里指定的名字 97 | 98 | 之后调用exportByAnnotation方法，就可以得到excel文件 -------------------------------------------------------------------------------- /src/main/java/com/duowan/leopard/officeutil/excel/ExportExcelUtil.java: -------------------------------------------------------------------------------- 1 | package com.duowan.leopard.officeutil.excel;
