TEST:
public static void main(String[] args) {
getJdbcTemplate();
List<Map<String, Object>> maps = jdbcTemplate.queryForList("select channel,paid_product,number_of_copies,total_paid_content,total_content,paid_percentage,total_number_of_pieces,total_episodes from summary_report");
ExcelWriter writer = ExcelUtil.getWriter("D:\\windows\\Desktop\\1.xlsx");
writer.setColumnWidth(-1, 20);
Map<String, String> objectMap = new LinkedHashMap<>();
objectMap.put("channel", "頻道");
objectMap.put("paid_product", "付費產品");
objectMap.put("number_of_copies", "部數");
objectMap.put("total_paid_content", "付費內容總量（部）");
objectMap.put("total_content", "內容總量（部）");
objectMap.put("paid_percentage", "付費占比（%）");
objectMap.put("total_number_of_pieces", "片單總數");
objectMap.put("total_episodes", "總集數");
writer.setHeaderAlias(objectMap);
layout(writer);
writer.write(maps, true);
// 關閉writer，釋放內存
writer.close();
}
public static void layout(ExcelWriter writer) {
//數字從0開始算 前面兩個數字是第幾行到第幾行合並 后面兩個數字是第幾列到第幾列合並
writer.merge(1, 4, 0, 0, null, true);
writer.merge(5, 7, 0, 0, null, true);
writer.merge(13, 18, 0, 0, null, true);
writer.merge(1, 4, 3, 3, null, true);
writer.merge(5, 7, 3, 3, null, true);
writer.merge(13, 18, 3, 3, null, true);
writer.merge(1, 4, 4, 4, null, true);
writer.merge(5, 7, 4, 4, null, true);
writer.merge(13, 18, 4, 4, null, true);
writer.merge(1, 4, 5, 5, null, true);
writer.merge(5, 7, 5, 5, null, true);
writer.merge(13, 18, 5, 5, null, true);
writer.merge(1, 11, 6, 6, null, true);
writer.merge(12, 18, 6, 6, null, true);
writer.merge(19, 24, 6, 6, null, true);
writer.merge(1, 4, 7, 7, null, true);
writer.merge(5, 7, 7, 7, null, true);
writer.merge(13, 18, 7, 7, null, true);
}
結果:
