1. 引入依赖
<dependency> <groupId>com.bstek.ureport</groupId> <artifactId>ureport2-console</artifactId> <version>2.2.9</version> </dependency>
2. 配置Servlet
1 @Bean 2 public ServletRegistrationBean<Servlet> ureport2Servlet(){ 3 return new ServletRegistrationBean<Servlet>(new UReportServlet(), "/ureport/*"); 4 }
注意:"/ureport/*" 是固定的
3. 配置自己的报表存储方式(我的是数据库存储)
1 /** 2 * 配置报表存储 3 * @return 4 */ 5 @Bean 6 public ReportProvider reportProvider() { 7 final String NAME = "数据库存储"; 8 final boolean DISABLED = false; 9 final String PREFIX = "DB:"; // 不能为空,否则报表存取不了 10 11 return new ReportProvider() { 12 13 @Override 14 public InputStream loadReport(String file) { 15 16 17 Template one = templateService.getOne(new QueryWrapper<Template>().eq(false, "name", file));//("fName", file)); 18 19 if(one!=null) { 20 return new ByteArrayInputStream(one.getTemplate()); 21 } 22 23 return null; 24 } 25 26 @Override 27 public void deleteReport(String file) { 28 29 templateService.remove(new QueryWrapper<Template>().eq(false,"name", file)); 30 31 } 32 33 @Override 34 public List<ReportFile> getReportFiles() { 35 List<Template> list = templateService.list(); 36 List<ReportFile> reportList = new ArrayList<>(); 37 38 for (Template template : list) { 39 reportList.add(new ReportFile(getCorrectName(template.getName()),
Date.from(template.getCreateTime().atZone(ZoneId.systemDefault()).toInstant()))); 40 } 41 return reportList ; 42 } 43 44 @Override 45 public void saveReport(String file, String content){ 46 47 Template one = templateService.getOne(new QueryWrapper<Template>().eq(false,"name", file)); 48 49 if(one == null){ 50 51 one = new Template(); 52 one.setName(file); 53 54 one.setTemplate(content.getBytes()); 55 56 one.setCreateTime(LocalDateTime.now()); 57 58 User user = (User) SecurityUtils.getSubject().getPrincipal(); 59 one.setCreator(user.getUsername()); 60 one.setCreatorID(user.getUserId()+""); 61 62 templateService.save(one); 63 }else{ 64 one.setTemplate(content.getBytes()); 65 one.setCreateTime(LocalDateTime.now()); 66 templateService.updateById(one); 67 } 68 69 70 } 71 72 /** 73 * 报表存储命名 74 */ 75 @Override 76 public String getName() { 77 78 return NAME; 79 } 80 81 @Override 82 public boolean disabled() { 83 return DISABLED; 84 } 85 86 @Override 87 public String getPrefix() { 88 89 return PREFIX; 90 } 91 92 private String getCorrectName(String name){ 93 if(name.startsWith(PREFIX)){ 94 name = name.substring(PREFIX.length(), name.length()); 95 } 96 return name; 97 } 98 99 100 }; 101 }
注意:① 前缀不能为空;② 获得模板列表时需要把前缀去掉;因为删除和加载模板时会自动加上前缀,假如原本前缀是DB:,那么进行加载和删除时,报表前缀则会变成 DB:DB:
4. 隐藏系统自带的保存配置
从UReport2核心包中取出ureport.properties放到类根路径下,修改配置
1 ## UReport2 配置文件 2 3 ureport.disableHttpSessionReportCache=true 4 5 #UReport2默认报表存储 6 ureport.disableFileProvider=true 7 ureport.fileStoreDir=d:/ureportfiles 8 9 ureport.debug=true
5. 配置内置数据源
1 /** 2 * 配置数据源 3 * @param dataSource 4 * @return 5 */ 6 @Bean 7 public BuildinDatasource buildinSystemDatasource(@Qualifier("systemDataSource")DataSource dataSource) { 8 return new BuildinDatasource() { 9 10 @Override 11 public String name() { 12 return "System"; 13 } 14 15 @Override 16 public Connection getConnection() { 17 try { 18 return dataSource.getConnection(); 19 } catch (SQLException e) { 20 21 e.printStackTrace(); 22 } 23 return null; 24 25 } 26 27 }; 28 } 29 30 /** 31 * 配置数据源 32 * @param dataSource 33 * @return 34 */ 35 @Bean 36 public BuildinDatasource buildinDemo1Datasource(@Qualifier("demo1DataSource")DataSource dataSource) { 37 return new BuildinDatasource() { 38 39 @Override 40 public String name() { 41 return "Demo1"; 42 } 43 44 @Override 45 public Connection getConnection() { 46 try { 47 return dataSource.getConnection(); 48 } catch (SQLException e) { 49 50 e.printStackTrace(); 51 } 52 return null; 53 54 } 55 56 }; 57 }
6. UReport2的使用可以参考
