EasyExcel 集成国际化实现导入导出

1、配置文件准备

1.1 pom.xml 导入EasyExcel 依赖包

     

        
        
            org.apache.commons
            commons-lang3
            3.9
        
        
            com.alibaba
            easyexcel
            1.1.1
        

1.2 配置i18n 国际化文件

  在resources 目录下，点击右键-->new --> Resource Bundle 创建国际化文件，如下图所示：

  

 

1.3  在yml 文件中配置国际化文件地址messages:  和 需要导出的excel文件头的国际化key

二、编写excel 配置文件

2.1 构造导出对象

import com.alibaba.excel.metadata.BaseRowModel;
import lombok.Data;
import org.apache.commons.lang3.ObjectUtils;

import javax.servlet.http.HttpServletResponse;
import java.util.List;



public class EasyExcelParams {

    /**
     * excel文件名（不带拓展名)
     */
    private String excelNameWithoutExt;
    /**
     * sheet名称
     */
    private String sheetName ="sheet1";
    /**
     * 是否需要表头
     */
    private boolean needHead = true;
    /**
     * 数据
     */
    private List data;

    /**
     * 数据模型类型
     */
    private Class dataModelClazz;

    /**
     * 响应
     */
    private HttpServletResponse response;


    public EasyExcelParams(String excelNameWithoutExt, String sheetName, List data, Class dataModelClazz, HttpServletResponse response ){
        this.excelNameWithoutExt = excelNameWithoutExt;
        this.sheetName = sheetName;
        this.data = data;
        this.dataModelClazz = dataModelClazz;
        this.response = response;
    }

    public EasyExcelParams(String excelNameWithoutExt, List data, Class dataModelClazz, HttpServletResponse response ){
        this.excelNameWithoutExt = excelNameWithoutExt;
        this.data = data;
        this.dataModelClazz = dataModelClazz;
        this.response = response;
    }

    /**
     * 检查不允许为空的属性
     */
    public boolean isValid() {
        return ObjectUtils.allNotNull(excelNameWithoutExt, data, dataModelClazz, response);
    }

    public String getExcelNameWithoutExt() {
        return excelNameWithoutExt;
    }

    public void setExcelNameWithoutExt(String excelNameWithoutExt) {
        this.excelNameWithoutExt = excelNameWithoutExt;
    }

    public String getSheetName() {
        return sheetName;
    }

    public void setSheetName(String sheetName) {
        this.sheetName = sheetName;
    }

    public boolean isNeedHead() {
        return needHead;
    }

    public void setNeedHead(boolean needHead) {
        this.needHead = needHead;
    }

    public List getData() {
        return data;
    }

    public void setData(List data) {
        this.data = data;
    }

    public Class getDataModelClazz() {
        return dataModelClazz;
    }

    public void setDataModelClazz(Class dataModelClazz) {
        this.dataModelClazz = dataModelClazz;
    }

    public HttpServletResponse getResponse() {
        return response;
    }

    public void setResponse(HttpServletResponse response) {
        this.response = response;
    }


}

2.2 配置获取excel 头的国际化key

import lombok.Data;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Configuration;

import java.util.List;


@Data
@Configuration
@ConfigurationProperties("excel")
public class ExcelHeaderName {

    private List userInfoHeader;

    private List exportFailure;

 
}

 

2.3 编写EasyExcelUtil 导出工具类

import com.alibaba.excel.ExcelReader;
import com.alibaba.excel.ExcelWriter;

import com.alibaba.excel.metadata.BaseRowModel;
import com.alibaba.excel.metadata.Sheet;
import com.alibaba.excel.support.ExcelTypeEnum;
import com.google.common.collect.Lists;
import com.***.fsd.ums.common.context.SpringBeanContext;
import com.***.fsd.ums.core.model.dto.EasyExcelParams;
import lombok.extern.slf4j.Slf4j;

import org.apache.commons.lang3.StringUtils;
import org.apache.commons.lang3.Validate;
import org.springframework.context.MessageSource;
import org.springframework.web.multipart.MultipartFile;


import javax.servlet.ServletOutputStream;
import javax.servlet.http.HttpServletResponse;
import java.io.*;
import java.net.URLEncoder;
import java.time.LocalDateTime;
import java.util.Collections;
import java.util.List;
import java.util.Locale;
import java.util.ResourceBundle;


/**
 * EasyExcel工具类
 *
 * @author [email protected]
 * @date 2018/11/19
 */
@Slf4j
public class EasyExcelUtil {


    /**
     * 读取 Excel(多个 sheet)
     *
     * @param excel    文件
     * @param clazz 实体类映射，继承 BaseRowModel 类
     * @return Excel 数据 list
     */
    public static List readExcel(MultipartFile excel, Class clazz) {
        ExcelListener excelListener = new ExcelListener();
        ExcelReader reader = getReader(excel, excelListener);
        if (reader == null) {
            return null;
        }
        for (Sheet sheet : reader.getSheets()) {

            sheet.setClazz(clazz);

            reader.read(sheet);
        }
        return excelListener.getDatas();
    }

    /**
     * 读取某个 sheet 的 Excel
     *
     * @param excel    文件
     * @param rowModel 实体类映射，继承 BaseRowModel 类
     * @param sheetNo  sheet 的序号 从1开始
     * @return Excel 数据 list
     */
    public static List
