SpingBoot解析Excel数据
前言
在最近的工作中，由于导入模板除了前三列（姓名、手机号、实发工资）固定；其余的列不固定，并且可以做到两个模板的数据都能够正常入库进行对应业务处理。
一、数据模板数据展示：
（1）模板一
（2）模板二
二、处理思路
观察两个模板的数据；结合面向对象的编程思想设计；我可以将两模板需要的获取的字段属性归纳为5个属性点：
注意：标题头在以下中不算！!!
索引（index）-- 相当于excel中所在列的下标列索引
列名称（name）-- 相当于excel中所在列的名称
列值（value）-- 相当于excel中所在列的值
是否存在合并单元格（isGrossField）-- 相当于excel中所在列的是否有合并单元格
合并的子元素（child）-- 相当于excel中所在列的是否有合并单元格下所包含的列
三、编程准备
1、实体类创建：
/**
* @project
* @Description
* @Author songwp
* @Date 2022/8/17 9:04
* @Version 1.0.0
**/
@Data
public class TreeExcel implements Serializable { private int index = 0; private String name; private String value; private boolean isGrossField; private List<TreeExcel> childs;
}
2、maven依赖的引入
<dependency>
<groupId>com.alibaba</groupId>
<artifactId>easyexcel</artifactId>
<version>2.2.0-beta2</version>
</dependency>
3、文件解析工具类的编写
import com.alibaba.excel.EasyExcelFactory;
import com.alibaba.excel.metadata.Sheet;
import com.alibaba.fastjson.JSONArray;
import java.io.FileInputStream;
import java.io.InputStream;
import java.util.*;
import java.util.concurrent.LinkedBlockingQueue; /**
* @project
* @Description
* @Author songwp
* @Date 2022/8/17 9:09
* @Version 1.0.0
**/
public class ExcelUtil { private String value = "empty"; private List<ExcelUtil> nodes; public String getValue() {
return value;
} public void setValue(String value) {
this.value = value;
} public void createExcelJson(List<TreeExcel> treeExcelList, int valueQueueSize, Queue<String> linkedValue, boolean firstStorey) {
if (null != nodes && !firstStorey) {
TreeExcel treeExcel = new TreeExcel();
treeExcel.setGrossField(true);
treeExcel.setName(treeExcel.getName());
treeExcel.setIndex(valueQueueSize - linkedValue.size()); List<TreeExcel> listElem = new ArrayList<>();
treeExcel.setChilds(listElem);
for (ExcelUtil tree : nodes) {
tree.createExcelJson(listElem, valueQueueSize, linkedValue, false);
}
treeExcelList.add(treeExcel);
} else {
if (firstStorey) {
for (ExcelUtil tree : nodes) {
tree.createExcelJson(treeExcelList, valueQueueSize, linkedValue, false);
}
return;
}
TreeExcel treeExcel = new TreeExcel();
treeExcel.setIndex(valueQueueSize - linkedValue.size());
treeExcel.setName(treeExcel.getName());
treeExcel.setValue(linkedValue.poll());
treeExcel.setGrossField(false);
treeExcelList.add(treeExcel);
}
} /**
* 获取树状数据结构
*
* @param inputStream
* @return
* @throws Exception
*/
public static JSONArray getExcelParseJSON(InputStream inputStream) throws Exception {
List<Object> read = EasyExcelFactory.read(inputStream, new Sheet(1, 0));
Map<String, Object> data = new HashMap<>();
int startDataLine = 0;
ExcelTreeUtils tree = new ExcelTreeUtils();
Queue<ExcelTreeUtils> queue = new LinkedBlockingQueue<>();
for (int i = 0; i < read.size(); i++) {
Object line = read.get(i);
ArrayList<String> lineList = (ArrayList<String>) line; if (i > 0 && null != lineList.get(0) && startDataLine == 0) {
startDataLine = i;
break;
}
Queue<ExcelTreeUtils> nextQueue = new LinkedBlockingQueue<>();
for (int j = 0; j < lineList.size(); j++) {
String elem = lineList.get(j);
if (null != elem) {
if (i == 0) {
List<ExcelTreeUtils> nodes = tree.getNodes();
if (null == nodes) {
nodes = new ArrayList<>();
tree.setNodes(nodes);
}
ExcelTreeUtils currentTree = new ExcelTreeUtils(elem, j);
nodes.add(currentTree);
queue.add(currentTree);
} else {
ExcelTreeUtils currentQueueTree = queue.peek();
while (j >= queue.peek().getExcelColumnIndex()) {
nextQueue.add(queue.poll());
currentQueueTree = queue.peek();
}
List<ExcelTreeUtils> nodes = currentQueueTree.getNodes();
if (null == nodes) {
nodes = new ArrayList<>();
currentQueueTree.setNodes(nodes);
}
ExcelTreeUtils currentTree = new ExcelTreeUtils(elem, j);
nodes.add(currentTree);
nextQueue.add(currentTree);
}
}
}
if (i > 0) {
queue = nextQueue;
}
Queue<ExcelTreeUtils> newQueue = new LinkedBlockingQueue<>();
while (null != queue.peek()) {
ExcelTreeUtils poll = queue.poll();
if (null != queue.peek()) {
poll.setExcelColumnIndex(queue.peek().getExcelColumnIndex());
} else {
poll.setExcelColumnIndex(i);
}
newQueue.add(poll);
}
queue = newQueue;
}
Queue<String> valueQueue = new LinkedBlockingQueue<>();
JSONArray resultJsonArray = new JSONArray();
for (int i = startDataLine; i < read.size(); i++) {
Object line = read.get(i);
ArrayList<String> lineList = (ArrayList<String>) line;
for (int j = 0; j < lineList.size(); j++) {
String elem = lineList.get(j);
if (null == elem) elem = "";
valueQueue.add(elem);
}
JSONArray jsonArray = new JSONArray();
tree.createStructeddJson(jsonArray, valueQueue.size(), valueQueue, true);
resultJsonArray.add(jsonArray);
}
return resultJsonArray;
}
}
4、测试类的编写
public static void main(String[] args) throws Exception {
InputStream fis = new FileInputStream("C:\\Users\\Lenovo\\Desktop\\工作簿1.xlsx");
JSONArray jsonArray = getExcelParseJSON(fis);
System.out.println(jsonArray);
TreeExcel treeExcel = new TreeExcel();
for (Object salaryObject : jsonArray) {
JSONArray salaryInfo = (JSONArray) salaryObject;
treeExcel.setIndex(Integer.parseInt(((Map) salaryInfo.get(0)).get("index").toString()));
treeExcel.setName(((Map) salaryInfo.get(0)).get("name").toString());
treeExcel.setValue(((Map) salaryInfo.get(0)).get("value").toString());
treeExcel.setGrossField(Boolean.getBoolean(((Map) salaryInfo.get(0)).get("isGrossField").toString()));
}
System.out.println(treeExcel);
}
5、日志输出展示
注意：因为自己的实体在循环外面展示；所以循环里面赋值存在覆盖；所以获取到的是最后一条数据对应信息
（1）模板一：
（2）模板二：
6、返回的json展示：
（1）模板一：
