Excel 多个Sheet 导出
上次贴了几个关于上传下载的 发现以接口的方式贴过来，读起来很混乱。直接索性贴上工具类，附上测试，自己根据需要再去封装比较好。我直接从项目里抠过来了，同事兼哥们写的……
1.1多sheetExcel工具类
package com.tm.util;
import java.util.List;
import java.util.Map;
public class ManySheetExcelUtils {
private String sheetName;// sheet名称
private List<PropSetter> props;// 属性设置
private List<Map<String, Object>> datas;// 数据信息
/******* getter、setter 省略 ******/
public ManySheetExcelUtils() {
super();
}
public ManySheetExcelUtils(String sheetName, List<PropSetter> props,
List<Map<String, Object>> datas) {
super();
this.sheetName = sheetName;
this.props = props;
this.datas = datas;
}
}
1.2组成Excel数据工具类
package com.tm.util;
/***
* 组成list数据的实体
*
* @author tablemiao
*
*/
public class PropSetter {
private String rOne; //第一行标题
private String rTwo; //第二行标题
private String prop;//对应的导出数据的字段名
private String type;//数据类型
private int width;//表格宽度
private boolean color;//颜色
/***** Getter 、Setter 省略********/
public PropSetter(String rOne, String prop, int width) {
super();
this.rOne = rOne;
this.prop = prop;
this.width = width;
}
public PropSetter(String rOne, String rTwo, String prop, int width) {
super();
this.rOne = rOne;
this.rTwo = rTwo;
this.prop = prop;
this.width = width;
}
public PropSetter(String rOne, String rTwo, String prop, int width,
boolean color) {
super();
this.rOne = rOne;
this.rTwo = rTwo;
this.prop = prop;
this.width = width;
this.color = color;
}
public PropSetter(String rOne, String rTwo, String prop, String type,
int width) {
super();
this.rOne = rOne;
this.rTwo = rTwo;
this.prop = prop;
this.type = type;
this.width = width;
}
public PropSetter() {
super();
}
}
1.3 组装加测试
