2. 如何在springboot 项目中实现各种报表导出、PDF文件导出
2.1使用IDEA创建maven工程
打开idea,New Project选择Maven Archetype ,创建web工程
右键新建Module
工程是这样的:
设置一下工程:
pom.xml变灰了,需要设置一下,把这个勾选去掉,点击“应用”
添加 springboot、ureport、数据库相关的依赖 pom.xml
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"><parent><artifactId>SpringBootDemo</artifactId><groupId>org.springboot.demo</groupId><version>1.0-SNAPSHOT</version></parent><modelVersion>4.0.0</modelVersion><artifactId>ureport</artifactId><dependencies><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot</artifactId><version>2.1.6.RELEASE</version></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-autoconfigure</artifactId><version>2.1.6.RELEASE</version></dependency><dependency><groupId>junit</groupId><artifactId>junit</artifactId><version>4.11</version><scope>test</scope></dependency><dependency><groupId>com.bstek.ureport</groupId><artifactId>ureport2-console</artifactId><version>2.2.9</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-context</artifactId><version>5.3.20</version></dependency><dependency><groupId>commons-configuration</groupId><artifactId>commons-configuration</artifactId><version>1.8</version></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId><version>2.1.6.RELEASE</version></dependency><dependency><groupId>org.mybatis</groupId><artifactId>mybatis</artifactId><version>3.5.6</version></dependency><dependency><groupId>org.mybatis</groupId><artifactId>mybatis-spring</artifactId><version>2.0.6</version></dependency><!-- https://mvnrepository.com/artifact/mysql/mysql-connector-java --><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId><version>8.0.21</version></dependency><!-- https://mvnrepository.com/artifact/com.alibaba/druid --><dependency><groupId>com.alibaba</groupId><artifactId>druid</artifactId><version>1.2.3</version></dependency><!--slf4j-Log4j驱动包 会自动添加4个对应包 --><dependency><groupId>org.slf4j</groupId><artifactId>slf4j-log4j12</artifactId><version>1.6.6</version></dependency><dependency><groupId>log4j</groupId><artifactId>log4j</artifactId><version>1.2.16</version></dependency><dependency><groupId>org.slf4j</groupId><artifactId>jcl-over-slf4j</artifactId><version>1.6.6</version></dependency><dependency><groupId>org.projectlombok</groupId><artifactId>lombok</artifactId><version>1.16.22</version></dependency></dependencies><pluginRepositories><pluginRepository><id>spring-releases</id><name>Spring Releases</name><url>https://repo.spring.io/libs-release</url></pluginRepository></pluginRepositories><properties><maven.compiler.source>8</maven.compiler.source><maven.compiler.target>8</maven.compiler.target></properties></project>
2.2添加yml配置信息
application.yml:
server:port: 8090servlet:context-path:
spring:http:encoding:force: trueenabled: truecharset: UTF-8datasource:driver-class-name: com.mysql.cj.jdbc.Driverurl: jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=utf8&serverTimezone=GMT%2B8&useSSL=false&allowMultiQueries=true&nullNamePatternMatchesAll=trueusername: rootpassword: 123456type: com.alibaba.druid.pool.DruidDataSourceresources:static-locations: classpath:/,classpath:/static/
2.3添加引用UReport2的Spring配置文件context.xml
放在resources
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsdhttp://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd"><!-- 创建context.xml是第六步,引入ureport2报表xml配置文件 --><import resource="classpath:ureport-console-context.xml" /><bean id="propertyConfigurer" parent="ureport.props"><property name="location"><value>classpath:config.properties</value></property></bean>
</beans>
2.4添加property文件
config.properties
#配置文件系统对应的报表文件地址
ureport.fileStoreDir=D:/work/ForTest/SpringBootDemo/ureport/src/main/webapp/WEB-INF/ureportfiles
# 是否禁用
ureport.disableFileProvider=false
ureport.debug=true
ureport.disableHttpSessionReportCache=false
# 配置ureport根路径
ureport.contextPath=/ureport
2.5新建webapp目录,新建WEB-INF
在WEB-INF下新建ureportfiles目录存放报表模板文件
2.7 创建启动类
Application.java
package org.springboot.demo;import com.bstek.ureport.console.UReportServlet;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.web.servlet.ServletRegistrationBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ImportResource;@SpringBootApplication
@ImportResource("classpath:context.xml")
public class Application {public static void main(String[] args) {try {SpringApplication.run(Application.class, args);}catch (Exception e){System.out.println(e.getMessage());}}// ureport2使用到servlet@Beanpublic ServletRegistrationBean buildUReportServlet(){return new ServletRegistrationBean(new UReportServlet(),"/ureport/*");}
}
执行启动 点击Application.java 右键启动项目
浏览器输入:http://localhost:8090/ureport/designer
就可以访问到ureport 模板设计页面了
2.8 新建 ureport 数据源类
新建 ureportSource.java
package org.springboot.demo.util;
import org.springframework.stereotype.Component;import java.util.ArrayList;
import java.util.List;
import java.util.Map;@Component("ureportSource")
public class ureportSource {/**** @param dsName* @param datasetName* @param parameters* @return*/public List<Map<String, Object>> usrInfo(String dsName, String datasetName, Map<String, Object> parameters) {List<Map<String, Object>> mapList = new ArrayList<>();mapList.add(parameters);return mapList;}
}
新建实体类
user.java
package org.springboot.demo.entity;import lombok.Data;
import java.io.Serializable;
@Data
public class user implements Serializable{private static final long serialVersionUID = -1518203115685933730L;private String userName;private String birthDate;private String sex;private String school;private String grade;private Integer age;private String address;
}
再次 重启项目
记得一定要重启,或者热部署
2.9 配置ureport数据源
ureport数据源 有三种:直连数据源、SpringBean连接、内置数据源
这个优先使用SpringBean连接,安全性高,使用简单
这里配置SpringBean连接、点击中间这个按钮
2.9.1新建数据源
Bean ID是我们建的那个java类的类名,这个需要对应上
2.9.2 添加数据集
确定后,点击userInfo 刷新,就可以看到实体类的属性了
2.9.3设计模板
分别给每个表格赋值
属性名称,使用“普通文本” 类型
属性值,使用“数据集” 类型
所有属性和值设置好后,点击保存
保存后,我们可以看到工程下生成了一个报表模板文件
3.0 新建导出excel、pdf公共类
ExportUtils.java
package org.springboot.demo.util;import com.bstek.ureport.export.ExportConfigureImpl;
import com.bstek.ureport.export.ExportManager;import java.io.FileOutputStream;
import java.io.OutputStream;
import java.util.Map;
import java.util.Objects;
/**
导出excel、pdf*/
public class ExportUtils {public static void exportPdf(ExportManager exportManager, String sourcePath, String targetPath, Map<String, Object> param) throws Exception {try {OutputStream fos = new FileOutputStream(targetPath);try {ExportConfigureImpl exportConfigure = new ExportConfigureImpl(sourcePath, param, fos);exportManager.exportPdf(exportConfigure);} catch (Exception e) {throw new Exception("exportPdf error", e);} finally {if (fos != null) {try {fos.close();}catch(Exception e) {throw new Exception("exportPdf error", e);}}}} catch (Exception e) {throw new Exception("exportPdf error", e);}}public static void exportExcel(ExportManager exportManager, String sourcePath, String targetPath, Map<String, Object> param) throws Exception {try {OutputStream fos = new FileOutputStream(targetPath);try {String ext = targetPath.substring(targetPath.indexOf(".") + 1);ExportConfigureImpl exportConfigure = new ExportConfigureImpl(sourcePath, param, fos);if (Objects.equals(ext, "xls")) {exportManager.exportExcel97(exportConfigure);} else {if (!Objects.equals(ext, "xlsx")) {throw new Exception("File name is not support!");}exportManager.exportExcel(exportConfigure);}} catch (Exception e) {throw new Exception("exportExcel error", e);} finally {if (fos != null) {try {fos.close();} catch (Exception e) {throw new Exception("exportExcel error", e);}}}} catch (Exception e) {throw new Exception("exportExcel error", e);}}}
3.1 新建测试类
urePortController.java
package org.springboot.demo.controller;import com.bstek.ureport.export.ExportManager;import lombok.SneakyThrows;import org.springboot.demo.util.ExportUtils;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;import java.util.HashMap;
import java.util.Map;@RestController
@RequestMapping("/user")
public class urePortController {@Autowiredprivate ExportManager exportManager;@SneakyThrows@RequestMapping("/generatePDF")public Map<String, Object> generatePDF(){Map<String,Object> dataMap = new HashMap<>();dataMap.put("userName","张三");dataMap.put("age","20");dataMap.put("sex","男");dataMap.put("grade","大三");dataMap.put("birthDate","2003-01-01");dataMap.put("address","广州市天河区");dataMap.put("school","广东工业大学");String filePath="D:/userInfo.pdf";ExportUtils.exportPdf(exportManager,"file:userInfo.ureport.xml",filePath,dataMap);//返回页面信息Map<String,Object> result = new HashMap<>();result.put("result","Success");result.put("data",dataMap);return result;}@SneakyThrows@RequestMapping("/generateExcel")public Map<String, Object> generateExcel(){Map<String,Object> dataMap = new HashMap<>();dataMap.put("userName","张三");dataMap.put("age","20");dataMap.put("sex","男");dataMap.put("grade","大三");dataMap.put("birthDate","2003-01-01");dataMap.put("address","广州市天河区");dataMap.put("school","广东工业大学");String filePath="D:/userInfo.xls";ExportUtils.exportExcel(exportManager,"file:userInfo.ureport.xml",filePath,dataMap);//返回页面信息Map<String,Object> result = new HashMap<>();result.put("result","Success");result.put("data",dataMap);return result;}}
