一、项目区域的介绍

各块区域------

Title----报表名,只在第一页显示

pageHeader-----放页码,时间,创建人,每一页都会显示出来

columnHeader-----列名

detail----循环的数据,比如说我们直接从数据库中得到数据,只用将字段拖到此区域,那么就会将所有的这个字段的值进行循环了。

              -----需要注意的是:table中因为放了数据,也会将这些数据接着循环。到头来,本来一个table已经将数据给循环完了,但是又由于detail的循环性质,将整个table又循环了。所以table是不能放在detail中的。这回循环table。

columnFooter-----可以用来统计此列数据。

pageFooter-------每页底部都会显示的,如页码

lastPageFooter----最后一页的底部,如日期,签名.....

Summary--------可能需要对几页(你的报表可能有几个页组成)的统计值。比如50个销售记录共占用了3页,那么放置这些统计记录的统计值最好的地方就是summary。     Summary只在最后一页出现。

二、软件使用

参考:https://jingyan.baidu.com/article/49ad8bce417c405834d8fac9.html

三、非数据源软件使用(我自己 总结)

3.1动态数据显示

四,java项目里写法

/**
	 * 打印运输计划明细 
	 * @param request
	 * @return
	 * @throws ServletException 
	 * @throws IOException 
	 * @throws JRException 
	 */
	@GetMapping("/getPrintTrunkDetail")
	public void getPrintTrunkDetail(HttpServletRequest request,HttpServletResponse response) throws JRException, IOException, ServletException {
		Map<String,Object> map = getParamMap(request);
		Map<String,Object> res = sortingService.getTrunkDetail(map);
		List<Map<String,Object>> mlist = new ArrayList<Map<String,Object>>();
		Map<String, Object>  data = (Map<String, Object>) res.get("topData");
		List<Map<String,Object>> tableData = (List<Map<String, Object>>) res.get("bodyData");
		
		System.out.println(tableData.size());
		data.put("TABLE_DATA", new JRBeanCollectionDataSource(tableData,false));
		data.put("DIST_DEPT_NAME", map.get("DIST_DEPT_NAME"));
		mlist.add(data);
		
		
		File jasperFile = ResourceUtils.getFile("classpath:reportTpl/printtrunk.jrxml");
		String jasperPath = jasperFile.getAbsolutePath();
		URL url = new URL("file:///"+jasperPath);
        InputStream is = url.openStream();
        JasperReport jasperReport = JasperCompileManager.compileReport(is);
        
        JasperreportUtils jasperreportUtils = new JasperreportUtils(request, response);
		//生成pdf
		jasperreportUtils.createExportDocument2(DocType.PDF, map, mlist, "运输计划明细",jasperFile);

 五、字体的选择

这时候你会发现中文无法显示

那你需要软件导入字体,

Jaspersoft Studio使用教程

同时,java项目依赖导入。

<dependency>
            <groupId>com.song</groupId>
            <artifactId>myfont</artifactId>
            <version>1.0.0</version>
        </dependency> 

这个是手动打入maven本地

jar包,还有软件的ttf我会提供
