文件打包下载excel导出和word导出

0.文件下载接口

        请求 GET

        /pm/prj/menu/whsj/download/{affixId}

       文件affixId多个id以逗号隔开。多个文件会以打包得形式。

 

1.Excel导出

        1.0接口

POST

127.0.0.1:8400/pm/io/exportExcel/year-plan-table-workflow/report

参数

[{"org":"011","report":"年度计划表","fiscalYear":"2023","mofDivCode":"371000"}] 

​ 

    1.1配置模板

数据要以 [entity.object]为模板配置，而且下方必须空一行不然导入会报错

​

1.2导入模板配置导出配置

​

多个集合需要配置多个查询条件，配置得服务接口要跟代码里面得对应服务接口得代码

package com.wenzheng.whsj.prj.export;

import com.wenzheng.module.common.excel.suite.service.DataSourceProvider;
import com.wenzheng.platform.core.bean.LoginUser;

 */
@Service(value = "gzw.yearPlanTableCloudProjectExport")
public class YearPlanTableCloudProjectExport implements DataSourceProvider {

	@Autowired
	private PmPrjConcentrateArgumentService pmPrjConcentrateArgumentService;


	@Override
	public List> findData(Map param) {
		LoginUser user = new LoginUser();
		user.setFiscalYear(param.get("fiscalYear").toString());
		user.setMofDivCode(param.get("mofDivCode").toString());
		user.setOrgCode(param.get("org").toString());

		YearPlanInfo yearPlanInfo = pmPrjConcentrateArgumentService.selectYearPlan(0, user, null, null, null, null);
		return yearPlanInfo.getCloudProjectList();
	}
}

2.导出word

     2.0接口

年度计划书导出 接口

POST

http://10.30.4.96:8400/pm/io/exportExcel/year-plan-book-workflow/report

参数

[{"org":"011","report":"年度计划书","fiscalYear":"2023","mofDivCode":"371000"}]

   2.1模板

​

2.2配置模板

​

2.3编写替换数据代码
