一、添加依赖到pom.xml
<!-- https://mvnrepository.com/artifact/commons-io/commons-io --> <dependency> <groupId>commons-io</groupId> <artifactId>commons-io</artifactId> <version>2.6</version> </dependency> <!-- https://mvnrepository.com/artifact/org.apache.commons/commons-csv --> <dependency> <groupId>org.apache.commons</groupId> <artifactId>commons-csv</artifactId> <version>1.6</version> </dependency>
二、上代码
package com.test.dbtest.tools;
import org.apache.commons.csv.CSVFormat;
import org.apache.commons.csv.CSVPrinter;
import org.apache.commons.io.FileUtils;
import java.io.FileWriter;
import java.io.IOException;
import java.util.List;
public class CsvOutputTool {
/**
* 写入csv文件
* @param headers 列头
* @param data 数据内容
* @param filePath 创建的csv文件路径
**/
public static void writeCsv(Object[] headers, List<Object[]> data, String filePath) throws IOException {
//初始化csvformat
CSVFormat formator = CSVFormat.DEFAULT.withRecordSeparator("\n");
//创建FileWriter对象
FileWriter fileWriter = new FileWriter(filePath, true);
//创建CSVPrinter对象
CSVPrinter printer = new CSVPrinter(fileWriter, formator);
//写入列头数据
printer.printRecord(headers);
if (null != data) {
//循环写入数据
for (Object[] lineData : data) {
printer.printRecord(lineData);
}
}
fileWriter.flush();
printer.close(true);
fileWriter.close();
}
}
