Springboot 集成 Ureport2 导出Excel报表、生成PDF文件

在Spring Boot中集成UReport2以导出Excel报表和PDF文件，你需要按以下步骤操作：

1. 添加UReport2的依赖到你的pom.xml文件中：

<dependency>
    <groupId>com.bstek.ureport</groupId>
    <artifactId>ureport2-console</artifactId>
    <version>你的UReport2版本</version>
</dependency>

2. 配置UReport2的定时任务（如果需要）和定时任务执行器。
3. 创建一个服务来处理报表的生成：

import com.bstek.ureport.console.UReportServlet;
import com.bstek.ureport.definition.report.ReportDefinition;
import com.bstek.ureport.export.Exporter;
import com.bstek.ureport.export.excel.ExcelExportor;
import com.bstek.ureport.export.pdf.PdfExportor;
import com.bstek.ureport.model.Report;
import com.bstek.ureport.utils.UReportUtils;
import org.springframework.stereotype.Service;
import org.springframework.web.context.WebApplicationContext;
 
import javax.annotation.PostConstruct;
import javax.servlet.ServletConfig;
import java.util.HashMap;
import java.util.Map;
 
@Service
public class UReportService {
 
    private ExcelExportor excelExportor;
    private PdfExportor pdfExportor;
 
    public byte[] exportExcel(String reportId) throws Exception {
        Report report = UReportUtils.getReport(reportId);
        return excelExportor.export(report);
    }
 
    public byte[] exportPdf(String reportId) throws Exception {
        Report report = UReportUtils.getReport(reportId);
        return pdfExportor.export(report);
    }
 
    @PostConstruct
    public void init() {
        Map<String, String> config = new HashMap<>();
        excelExportor = new ExcelExportor();
        pdfExportor = new PdfExportor();
 
        ServletConfig servletConfig = new ServletConfig() {
            @Override
            public String getServletName() {
                return "UReportServlet";
            }
 
            @Override
            public ServletContext getServletContext() {
                return null; // 你的Spring应用上下文
            }
 
            @Override
            public String getInitParameter(String name) {
                return config.get(name);
            }
 
            @Override
            public Enumeration<String> getInitParamet
