一、环境搭建

　　在spring-mvc.xml加入

<!-- jasperReports--><import resource="classpath*:spring-mvc-jasperreports.xml"/>

spring-mvc-jasperreports.xml具体配置代码：

<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"       xmlns:p="http://www.springframework.org/schema/p"       xmlns:context="http://www.springframework.org/schema/context" xmlns:mvc="http://www.springframework.org/schema/mvc"       xsi:schemaLocation="       http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.2.xsd       http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.2.xsd       http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.2.xsd">    <!-- jasperReports报表集成视图解析器 -->    <bean id="jasperReportsViewResolver"          class="org.springframework.web.servlet.view.jasperreports.JasperReportsViewResolver">        <!-- 执行优先级，值越小优先级越高 -->        <property name="order" value="0"/>        <!-- 处理视图返回 -->        <property name="viewClass" value="com.silverdata.smart.report.jasperreports.JasperReportsView"/>        <property name="prefix" value="/WEB-INF/jasper/"/>        <property name="suffix" value=".jasper"/>        <!-- 可通过配置此项用来过滤是否执行此视图解析器 -->        <!-- <property name="viewNames" value="rpt*"/>   -->        <!-- 报表数据源 -->        <property name="jdbcDataSource" ref="dataSource"/>        <!-- 扩展参数 -->        <property name="exporterParameters">            <map>                <!-- 指定格式报表的内容编码 -->                <entry key="net.sf.jasperreports.engine.JRExporterParameter.CHARACTER_ENCODING">                    <value>UTF-8</value>                </entry>                <!-- 通过Web访问时图片的URI -->                <!-- <entry key="net.sf.jasperreports.engine.export.JRHtmlExporterParameter.IMAGES_URI">                      <value type="java.lang.String">/jasper/image.jsp?image=</value>                  </entry> -->                <!-- 图片目录的绝对路径 -->                <!-- <entry key="net.sf.jasperreports.engine.export.JRHtmlExporterParameter.IMAGES_DIR_NAME">                      <value type="java.lang.String">D:\\work\\***\\framework\\tmp</value>                </entry> -->                <!-- 是否输出图片到目录 -->                <!-- <entry key="net.sf.jasperreports.engine.export.JRHtmlExporterParameter.IS_OUTPUT_IMAGES_TO_DIR">                      <value type="java.lang.String">true</value>                  </entry>  -->            </map>        </property>    </bean></beans>

jar包需要：

<!-- jasperreports --><dependency>    <groupId>net.sf.jasperreports</groupId>    <artifactId>jasperreports</artifactId></dependency><dependency>    <groupId>net.sf.jasperreports</groupId>    <artifactId>jasperreports-fonts</artifactId></dependency>

二、jasperreports报表设计步骤

1.新建项目配置jar包

若jar包unbond未找到~检查是否目录路径是纯英文的~中文不识别

2.新建报表模版~一般中国的报表直接用空白A4去做

3.若要用测试数据展现表格配置

然后根据需要查询字段表~加入测试数据一般也不使用

4.页面设计

5.配置

样式

编译

java代码部分：

开发代码：

public ModelAndView apply(ModelAndView modelAndView,@PathVariable("id") Long id) {　　注释部分为二维码生成    /*List<Order> list = Lists.newArrayList();    Order order;    for (int i = 0; i < 100; i++) {        order = new Order(i, "供应商" + i, "厦门市" + i + "号楼", i % 2 == 0 ? "厦门" : "周口", new Timestamp(System.currentTimeMillis()));        list.add(order);    }    ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();    QRCodeUtils.encode("PE12873619284611231213", 100, 100, byteArrayOutputStream);

    InputStream file = new ByteArrayInputStream(byteArrayOutputStream.toByteArray());

    Map<String, Object> m = new HashMap<String, Object>();    m.put("QRCodeString", "PE12873619284611231213");    m.put("QRCode", file);    m.put("image", "E:\\ideaWorkSpace\\pipegallery\\pipegallery-operation\\src\\main\\webapp\\WEB-INF\\jasper\\silhouette.jpg");    return ReportUtils.toPdf("Silhouette4", m, list);*/

    List<ApplyDetails> applyDetailsList = Lists.newArrayList();    Map<String, Object> m = new HashMap<String, Object>();    List<Map> list =materialsIeApplyDetailsService.getAllByDynamicWhere(id);    MaterialsIeApply materialsIeApply=materialsIeApplyService.get(id);    m.put("APPLICANT",materialsIeApply.getApplicant());//申请人    m.put("ORDERNO",materialsIeApply.getOrderno());    m.put("IEAPPLYTYPE","0".equals(materialsIeApply.getIeApplyType())?"租用":"使用");    m.put("PLANGETDATE",materialsIeApply.getPlanGetDate());//领用时间    m.put("PLANRETURNDATE",materialsIeApply.getPlanReturnDate());//归还时间    m.put("AUDIT",materialsIeApply.getAuditId());//审核人    m.put("AUDITDATE",materialsIeApply.getApplyDate());//审核时间    //(0未提交、1待审核、2已审核、3未通过、4打回、5部分出库、6全部出库、7作废)    m.put("APPROVALSTATE", ReturnMaterialsIeApplyString.returnString(materialsIeApply.getApprovalState()));//申请单状态    m.put("APPLYDATE",materialsIeApply.getApplyDate());//申请提交时间    m.put("REASON",materialsIeApply.getReason());    m.put("REMARK",materialsIeApply.getRemark());    m.put("AUDITOPINION",materialsIeApply.getAuditOpinion());//审核意见    ApplyDetails applyDetails;    for (Map map:list){        applyDetails=new ApplyDetails(map.get("materialsname").toString(),map.get("suppliername").toString(),Integer.parseInt(map.get("amount").toString()),map.get("remark").toString(),map.get("spec").toString(),"1");        applyDetailsList.add(applyDetails);    }    return ReportUtils.toPdf("MaterialsIeApply", m, applyDetailsList);}
