Jasperreports+jaspersoft studio学习教程(七)- 子报表Subreport(父子报表互相传值)

有很多人都说Jasperreports不适合中国式复杂报表,实际上运用好父子报表可以解决大部分问题了。例如下面的表。每个学生的学科数目不固定,且每个学生后有相当于小计的平均分。有点复杂度的报表,可以使用子报表解决。

8.1 设计报表模板

8.1.1 新建主模板DemoReport6_main.jrxml,创建Paramters :title(java.lang.String)、date(java.lang.String)、SUBREPORT_DIR(java.lang.String),创建Fields :stuNo(java.lang.Integer)、

stuName(java.lang.String)、subjectList(java.util.List)

 

8.1.2 设计模板表头如下,注意宽度:

8.1.3 新建子模板DemoReport6_sub.jrxml,只保留DetailBand(Height设置为20),并设置模板的宽500,高20,且四周Margin都为0

8.1.4 转到DemoReport6_main主模板,将Subreport组件拖入到Detail中,跳出Subreport界面

8.1.5 将stuNo和stuName拖入到Detail中

8.1.6 转到DemoReport6_sub子模板,新建Fields:subjectName(String)、teacherName(String)、score(java.lang.Double).拖入到Detail中,注意宽度和主模板保持一致

8.1.7 新建Variables,命名为averageScore

8.1.8 转回DemoReport6_mian主模块,新建Variables,命名为getAverageScore

拖入到Detail Band中,设置好字体样式

点击 $V{getAverageScore} 显示Properties,设置Appearance中Position Type选中为Fix Relation To Bottom(同样将“平均分”如此设置)

设置TextField的Evaluation Time 选中为Band

8.1.9 将Subreport、$F{stuNo}、$F{stuName}放进一个Element Group里,直接在source中添加(未找到图形化操作)

<detail>

       ...

           <elementGroup>

              <subreport>

                  ...

              </subreport>

              <textField>

                  ... <textFieldExpression><![CDATA[$F{stuNo}]]></textFieldExpression>

              </textField>

              <textField>

                  ...

                  <textFieldExpression><![CDATA[$F{stuName}]]></textFieldExpression>

              </textField>

           </elementGroup>

       ...

    </detail>

保存后:

8.1.10 点击 $F{stuNo} 显示Properties,设置Position Type 为Float,Stretch Type为 ElementGroupHeight,把stuNo和Subreport也如此设置。

8.1.11 点击Subreport 显示Properties,在Subreport中设置Exception为$P{SUBREPORT_DIR}+"DemoReport6_sub.jasper",Data Source Expression为

newnet.sf.jasperreports.engine.data.JRBeanCollectionDataSource($F{subjectList})

点击 Edit Return Values

保存主模板,子模板,放到项目中的jrxml中。

8.2 编写Servlet注入数据源

8.2.1 新建 Student类和Subject类

8.2.2 新建JasperServlet6,doGet内容如下:

8.3 启动tomcat,访问servlet,查看html文件

代码如下:

DemoReport6_main.jrxml
