Spring 4 Jasper Report integration example with mysql database in eclipse

This tutorial shows that how to generate dynamic reports from database using Jasper Reports in Spring 4 mvc. Jasper Reports uses XML templates to generate reports that can be saved/opened as HTML, PDF or CSV, XLS. In this example, let us create jasper report to generate the list of employees who are working more or equal to given year. We will get no of years and report format as input. Assume that spring 4 framework is configured in eclipse for this example.

As JRHtmlExporter is depreciated, i have used HtmlExporter for generating html report. The dependencies for HtmlExporter are as follows.

Let us see the Steps to generate report with the data stored in MySql database using JasperReports and Spring 4

Step 1: Create a table emp_master in MySql Database with necessary fields. (In our example, fields used emp_code, EmpName, Salary, Doj)

DDL to create table

create table emp_master (emp_code varchar(10), EmpName varchar(100),Salary decimal, Doj date);

insert some rows into the table.

insert into emp_master values (‘5000’, ‘Kumar’, 4500000, ‘2000-01-01’);

insert into emp_master values (‘5001’, ‘Jacob’, 4000000, ‘2002-01-01’);

select Emp_code, EmpName, Salary, Doj from emp_master where TIMESTAMPDIFF(YEAR, Doj, CURDATE())>=9

Step 2: Create JRXML (JREmp1.jrxml) which is a reusable template that can be used by Jasper report engine to populate data from the database. This XML template includes various sections like Title, queryString, Page Header/Footer, Column Header/Footer, etc.. Write your query in the queryString part. Query parameter (noy) can be embedded using the $P{noy) where noy is the number of year. The JRXML file(JREmp1.jrxml) used in this example is given below.

The above XML template can be created either by using IReports OR by editing the existing XML template file as per your requirement.The below lines mentioned in the XML template are used to define the external parameters.

 

 

<parameter name="Title" class="java.lang.String"/>
<parameter name="noy" class="java.lang.Integer"/>

Step 3: Place the XML template in jasper folder under WebContent folder.The following code compiles the JREmp1.jrxml and creates JREmp1.jasper in the same folder jasper.

JasperCompileManager.compileReportToFile(request.getSession().getServletContext().getRealPath("/jasper/" + fileName + ".jrxml"),request.getSession().getServletContext().getRealPath("/jasper/" + fileName + ".jasper"));

JREmp1.jasper can be used multiple times with different sets of parameters & data to generate dynamic report

Step 4: Load the .jasper file with JRLoader.loadObjectFromFile method which returns the JasperReport instance.

File reportFile = new File( request.getSession().getServletContext().getRealPath("/jasper/" + fileName + ".jasper"));
        // If compiled file is not found, then compile XML template
        if (!reportFile.exists()) {
                   JasperCompileManager.compileReportToFile(request.getSession().getServletContext().getRealPath("/jasper/" + fileName + ".jrxml"),request.getSession().getServletContext().getRealPath("/jasper/" + fileName + ".jasper"));
            }
            JasperReport jasperReport = (JasperReport) JRLoader.loadObjectFromFile(reportFile.getPath());
           return jasperReport;
        }

 

Step 5: Now pass the jasperReport instance, parameters as HashMap and connection object to methods like JasperRunManager.runReportToPdf(), JasperManager.fillReport() to generate the report as PDF or HTML.

Now let us see the complete code

The following JSP (loadJasper.jsp) captures no of years and Report format from the user.

loadJasper.jsp

    <h2>Spring MVC Jasper Report example</h2>
 
    <h3>Generate Report for Employees Working More than or equal to given year</h3>
 
    <form:form method="POST" action="generateReport.do" commandName="jasperInputForm">
 
        <table id="reptbl" width="350px" border="1">

        <tr>
            <td>
                Enter Number of Years <form:input path="noofYears" id="noofYears"/>
                <input type="submit"  value="Generate Employee List"  />
            </td>
            <td>
                <form:radiobuttons path="rptFmt" items="${jasperRptFormats}"/>
            </td>
 
        </tr>
 
         </table>  
 
    </form:form>
 
</body>
</html>

Model Form :

JasperInputForm.java

package net.javaonline.spring.jasper.form;
 
import org.hibernate.validator.constraints.NotEmpty;
 
public class JasperInputForm {
    @NotEmpty
    private String noofYears;
    private String rptFmt="Html";
 
    public String getRptFmt() {
        return rptFmt;
    }
 
    public void setRptFmt(String rptFmt) {
        this.rptFmt = rptFmt;
    }
 
    public String getNoofYears() {
        return noofYears;
    }
 
    public void setNoofYears(String noofYears) {
        this.noofYears = noofYears;
    }
 
    }

The following is the controller code. loadJasper method loads view (loadJasper.jsp) page. generateReport method generates the report.
