springboot2 集成ureport2 進行 在線 excel word pdf等操作

1. 引入依賴

    <dependency>
        <groupId>com.bstek.ureport</groupId>
        <artifactId>ureport2-console</artifactId>
        <version>2.2.9</version>
    </dependency>
   

2. application.properties添加配置

      ureport.disableHttpSessionReportCache=false
       
      ureport.disableFileProvider=true
      ureport.fileStoreDir=/WEB-INF/ureportfiles
   
      ureport.debug=true
   

3. 實體類

   
   import lombok.Data;
   
   import javax.persistence.*;
   import java.io.Serializable;
   import java.util.Date;
   
   @Data
   @Table(name = "ureport_file_tbl")
   public class UreportFileEntity implements Serializable {
   
       private static final long serialVersionUID = 1L;
   
       @Id
       @Column(name = "id_")
       @GeneratedValue(strategy = GenerationType.IDENTITY)
       private Long id;
   
       @Column(name = "name_")
       private String name;
   
       @Column(name = "content_")
       private byte[] content;
   
       @Column(name = "create_time_")
       private Date createTime;
   
       @Column(name = "update_time_")
       private Date updateTime;
   }
   
   

4. 配置存儲器

import java.io.ByteArrayInputStream;
import java.io.InputStream;
import java.util.ArrayList;
import java.util.Date;
import java.util.List;

import com.schinta.akt.entity.UreportFileEntity;
import com.schinta.akt.service.UreportFileService;
import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;

import com.bstek.ureport.provider.report.ReportFile;
import com.bstek.ureport.provider.report.ReportProvider;

import lombok.Setter;

/**
 * @author 7788
 * @description 自定義報表存儲器
 */
@Setter
@Component
@Slf4j
public class MysqlProvider implements ReportProvider {
    private static final String NAME = "ureport-provider";

    private String prefix = "report-";

    private boolean disabled = false;

    @Autowired
    private UreportFileService ureportFileService;

    /**
     * 根據報表名加載報表文件
     *
     * @param file 報表名稱
     * @return 返回的InputStream
     */
    @Override
    public InputStream loadReport(String file) {
        UreportFileEntity ureportFileEntity = ureportFileService.queryUreportFileEntityByName(getCorrectName(file));
        byte[] content = ureportFileEntity.getContent();
        ByteArrayInputStream inputStream = new ByteArrayInputStream(content);
        return inputStream;
    }

    /**
     * 根據報表名，刪除指定的報表文件
     *
     * @param file 報表名稱
     */
    @Override
    public void deleteReport(String file) {
        ureportFileService.deleteReportFileByName(getCorrectName(file));
    }

    /**
     * 獲取所有的報表文件
     *
     * @return 返回報表文件列表
     */
    @Override
    public List<ReportFile> getReportFiles() {
        List<UreportFileEntity> list = ureportFileService.queryReportFileList();
        List<ReportFile> reportList = new ArrayList<>();
        for (UreportFileEntity ureportFileEntity : list) {
            reportList.add(new ReportFile(ureportFileEntity.getName(), ureportFileEntity.getUpdateTime()));
        }
        return reportList;
    }

    /**
     * 保存報表文件
     *
     * @param file    報表名稱
     * @param content 報表的XML內容
     */
    @Override
    public void saveReport(String file, String content) {
        file = getCorrectName(file);
        UreportFileEntity ureportFileEntity = ureportFileService.queryUreportFileEntityByName(file);
        Date currentDate = new Date();
        if (ureportFileEntity == null) {
            ureportFileEntity = new UreportFileEntity();
            ureportFileEntity.setName(file);
            ureportFileEntity.setContent(content.getBytes());
            ureportFileEntity.setCreateTime(currentDate);
            ureportFileEntity.setUpdateTime(currentDate);
            ureportFileService.insertReportFile(ureportFileEntity);
        } else {
            ureportFileEntity.setContent(content.getBytes());
            ureportFileEntity.setUpdateTime(currentDate);
            ureportFileService.updateReportFile(ureportFileEntity);
        }
    }

    /**
     * @return 返回存儲器名稱
     */
    @Override
    public String getName() {
        return NAME;
    }

    /**
     * @return 返回是否禁用
     */
    @Override
    public boolean disabled() {
        return disabled;
    }

    /**
     * @return 返回報表文件名前綴
     */
    @Override
    public String getPrefix() {
        return prefix;
    }

    /**
     * @param name 名稱
     * @return String
     * 獲取沒有前綴的文件名
     */
    private String getCorrectName(String name) {
        if (name.startsWith(prefix)) {
            name = name.substring(prefix.length());
        }
        return name;
    }


}

5. 配置數據源

import java.sql.Connection;
import java.sql.SQLException;
import javax.servlet.Servlet;
import javax.sql.DataSource;

import com.bstek.ureport.console.UReportServlet;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.web.servlet.ServletRegistrationBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.ImportResource;
import com.bstek.ureport.definition.datasource.BuildinDatasource;

/**
 * @author 7788
 * 內置數據源，實現BuildinDatasource接口
 */
@Configuration
@ImportResource("classpath:ureport-console-context.xml")
public class UreportDataSource implements BuildinDatasource {
    private static final String NAME = "UreportDataSource";
    private final Logger log = LoggerFactory.getLogger(UreportDataSource.class);

    @Autowired
    private DataSource dataSource;

    @Override
    public String name() {
        return NAME;
    }

    @Override
    public Connection getConnection() {
        try {
            return dataSource.getConnection();
        } catch (SQLException e) {
            log.error("Ureport 數據源 獲取連接失敗！");
            e.printStackTrace();
        }
        return null;
    }


    /**
     * 注冊 UReportServlet
     * 值為“/ureport/*”的 urlMappings 是一定不能變的，否則系統將無法運行。
     */
    @Bean
    public ServletRegistrationBean<Servlet> ureportServlet() {
        ServletRegistrationBean<Servlet> bean = new ServletRegistrationBean<>(new UReportServlet(), "/ureport/*");
        return bean;
    }

}
