Jasper and Spring

Overview
I'm working in a project where we have to integrate Jasper Reports with Spring 2.5.6. After looking into the Spring Reference, I found that in the section 14.7. JasperReports there are all the details needed for the configuration of Jasper Report with Spring. Moreover, I found in the CVS an example of Jasper and Spring integration. However I was not able to find out a configuration with annotations based controllers. Therefore, I decided to code an annotation based version of the Jasper Demo Spring Example...

Controller
Here an example of configuration by using annotation based @Controller:

@Controller
public class ReportController extends MultiActionController {
// other code

 @RequestMapping(value = "/exporterParameters.html")
 public ModelAndView handleExporterParameters(HttpServletRequest request,
         HttpServletResponse response) throws Exception {
     return new ModelAndView("htmlReport", getModel());
 }
}

web.xml
Here the configuration in the web.xml:

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
<display-name>Jasper Reports</display-name>

<servlet>
    <servlet-name>jrtest</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <load-on-startup>2</load-on-startup>
</servlet>

<servlet-mapping>
    <servlet-name>jrtest</servlet-name>
    <url-pattern>*.action</url-pattern>

</welcome-file-list>
<!-- log4j -->
<context-param>
    <param-name>log4jConfigLocation</param-name>
    <param-value>classpath:log4j.properties</param-value>
</context-param>
<listener>
    <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>
</listener>
</web-app>

jrtest-servlet.xml
Here instead the jrtest-servlet.xml. It is important to note the bean called htmlReport which contains the details related to the Jasper report definition. Moreover, here you can also see how to set the JRHtmlExporterParameter export properties.

<?xml version="1.0" encoding="UTF-8"?>
<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"
xsi:schemaLocation="
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-2.5.xsd">

  <context:component-scan base-package="org.springframework.samples.jasperdemo.web"/>
  <bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping"/>
  <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"/>
  <context:annotation-config />

  <!-- If a JasperReports view requires more complex configuration then use the BeanNameViewResolver to
           map a given view name to a given view bean -->

  <bean id="nameViewResolver" class="org.springframework.web.servlet.view.BeanNameViewResolver"/>

  <bean id="htmlReport" class="org.springframework.web.servlet.view.jasperreports.JasperReportsHtmlView">
      <property name="url">
          <value>/WEB-INF/reports/simpleReport.jasper</value>
      </property>
      <property name="exporterParameters">
          <map>
              <entry key="net.sf.jasperreports.engine.export.JRHtmlExporterParameter.HTML_FOOTER">
                  <value>Footer by Spring!&lt;/td&gt;&lt;td width="50%"&gt;&amp;nbsp; &lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;&lt;/body&gt;&lt;/html&gt;</value>
              </entry>
          </map>
      </property>
  </bean>

</beans>

So, in this simple example you can see how to use Jasper with Spring with the controller based annotations.
I hope this help!
