web application is made with gradle sts project
i've added view Resolver like this
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/view/" />
<property name="suffix" value=".html" />
</bean>
it is hitting the url but wont return any view
#Controller
public class HomeController {
#RequestMapping(value = DatahubClientConstant.CLIENT_URL , method = RequestMethod.GET )
public ModelAndView getTestPage(HttpServletRequest request, HttpServletResponse response) throws Exception {
//System.out.println("Hello World");
return new ModelAndView("home");
}
}
Tried to sysout it works
It doesnt return any view?
After Some Research i have found out that InternalViewResolver does not resolve html pages directly that's why i was not able to get the view.
Spring MVC ViewResolver not mapping to HTML files
This was a helpful question in resolving the issue. All it is doing is loading the html as static content.

I need help with JasperReports and Spring MVC. I can export everything, but I can't set the filename in the output PDF/Excel that my software exports.
In my dispatcher-servlet I have this bean :
<!-- ViewResolver JasperReports -->
<bean id="jasperViewResolver" class="org.springframework.web.servlet.view.jasperreports.JasperReportsViewResolver">
<property name="prefix" value="classpath:/jasper/" />
<property name="reportDataKey" value="dataSource" />
<property name="suffix" value=".jrxml" />
<property name="viewNames" value="Report_*" />
<property name="viewClass">
<value>org.springframework.web.servlet.view.jasperreports.JasperReportsMultiFormatView</value>
</property>
<property name="order" value="1" />
</bean>
That is the ViewResolver provided by Spring MVC.
I have a function in my BaseController ( abstract controller extended by all the #Controller ) :
protected String exportReport(String reportName, String formatoReport, Model model, JRDataSource dataSource) {
model.addAttribute("dataSource", dataSource);
model.addAttribute("format", formatoReport);
return reportName;
}
So, what I do is simply returning this view name from all my #RequestMapping :
#RequestMapping(..something)
public String functionName(...something else) {
.. do some stuff
return exportReport("Report_docIngresso", EFormatoReport.XLS, model, jrDataSource);
}
This works. The export is perfect, but I didn't find the way to set the filename of the exported pdf/excel, that comes out like the latest part of the URL I called before exporting the report.
I already tried to set in the HttpServletResponse the content-disposition with the filename, but it didn't work.
Thanks a lot,
Marco
Try setting the Content-Disposition HTTP response header:
#RequestMapping(..something)
public String functionName(HttpServletResponse response, ...something else) {
.. do some stuff
String header = "inline; filename=myfile.xls";
response.setHeader("Content-Disposition", header);
return exportReport("Report_docIngresso", EFormatoReport.XLS, model, jrDataSource);
}
(Note I saw just now your concluding comment that you tried without success to set the content disposition header. Well.. I can only say it worked for me in a similar setup.)
I have a product page which displays all products
home.jsp:
<a class="campaign" href="page/dynamic/product1">
Controller
#RequestMapping(value="/page/dynamic/{pagename}")
public ModelAndView loadProductPage(ModelMap model, #PathVariable("pagename") String pagename) {
model.addAttribute("productname",pagename);
return new ModelAndView("products/"+pagename+"/"+pagename);
}
It is getting redirected to the product1 page. Product1 page has a link called features
product1.jsp
<li>Features</li>
Controller
#RequestMapping(value="/page/loadpage/{choosedProduct}/{linkChoosed}")
public ModelAndView loadProductMenuPages(ModelMap model, #PathVariable("linkChoosed") String linkChoosed, #PathVariable("choosedProduct") String choosedProduct) {
System.out.println("Loading links here");
System.out.println("cones gere");
System.out.println("Product Choosed" + choosedProduct);
System.out.println("Link Choosed" + linkChoosed);
return new ModelAndView("products/"+choosedProduct+"/"+linkChoosed);
}
It is not getting redirected to the "features page", but throws an error:
HTTP Status 404 - /controller/WEB-INF/views/products/loadpage/loadpage.jsp
What should I need to do to get redirected to features page?
EDIT:
Adding servlet-context.xml informed in comment:
<beans:bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<beans:property name="prefix" value="/WEB-INF/views/" />
<beans:property name="suffix" value=".jsp" />
</beans:bean>
In your configuration file please configure below tag
<bean id="PageRedirect"
class="org.springframework.web.servlet.view.RedirectView">
<property name="url" value="RedirectPage.jsp" />
</bean>
And in your controller
#Override
protected ModelAndView handleRequestInternal(HttpServletRequest request,
HttpServletResponse response) throws Exception {
return new ModelAndView("PageRedirect");
}
I am a spring newbie and have a question about view resolution. I am changing a webapp that I downloaded online and it uses the simple view resolver strategy:
<bean id="jspViewResolver"
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="viewClass" value="org.springframework.web.servlet.view.JstlView" />
<property name="prefix" value="/WEB-INF/view/" />
<property name="suffix" value=".jsp" />
</bean>
and I keep getting 404 errors for view resolution and I am suspecting that it uses some sort of rewriting / filtering mechanism. Is there a log that I can view in tomcat / Spring class that I can override in order to understand what file is Spring trying to look for when resolving an incoming request?
I understand the operation of InternalResourceViewResolver which strips file name extensions. But what if the request does not have an extension? For instance:
#RequestMapping("/foo")
protected ModelMap render() { return new ModelMap(); }
Then what is the view name that will be resolved to in this case?
See this link for log4j integration
Spring-mvc doesn't use any file for request handling, it uses controllers and requestmapping to map the request to a controller and respective method if any.
The InternalResourceViewResolver that you have written Resolves “view name” that is returned from the controller class to a JSP page residing in /WEB-INF/view/ directory.
an example
#Controller
public class SimpleController{
#RequestMapping("/home")
public String homeMapper(Model model) {
return "home";
}
}
here homeMapper method will be called if you try to access "home" and as it returns home the relative jsp to be rendered is "home.jsp" should be present in /WEB-INF/view/
For more information see spring mvc reference or any tutorial.
How to map a jsp for a url in spring 3 without requestmapping to any controller.
eg. /login to login.jsp without having any userdefined controller in between
Like URLFILENAMECONTROLLER in spring2.5, similarly in spring 3
You can use this paragraph from Spring docs for reference. In short, you can do in several ways one of them with view-controller annotation. The other way when using Java Config:
#EnableWebMvc
#Configuration
public class WebConfig extends WebMvcConfigurerAdapter {
#Override
public void addViewControllers(ViewControllerRegistry registry) {
registry.addViewController("/login").setViewName("login");
}
}
Where the code maps request for /login to /WEB-INF/views/login.jsp view if the view resolver is defined as in the previous answer.
You can do this:
<mvc:view-controller path="/login" view-name="login"/>
Assuming that you have defined a ViewResolver, something like this:
<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/views/" />
<property name="suffix" value=".jsp" />
</bean>
This will resolve a request to /login to a /WEB-INF/views/login.jsp page
I am attempting to use Spring 3' MVC support for annotated controllers in my web application.
In my application-context.xml, I've added the following:
<mvc:annotation-driven />
<context:component-scan base-package="com.abc.def.etc"/>
<bean id="jspViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>
<property name="prefix" value="/WEB-INF/jsp/"/>
<property name="suffix" value=".jsp"/>
<property name="order" value="1" />
</bean>
My Controller is annotated as follows:
#Controller
#RequestMapping("/optimizerRules")
public class OptimizerRulesController {
private OptimizerRulesService optimizerRulesService;
private static final Log LOG = LogFactory.getLog(OptimizerRulesController.class);
public OptimizerRulesController()
{
LOG.info("Initializing OptimizerRulesController");
}
#RequestMapping(method = RequestMethod.GET)
public ModelAndView getRuleAttributesAndRules(ModelMap model)
{
LOG.info("Entering getRuleAttributesAndRules method");
}
When I start up my application I can see in my logs that the OptimizerRulesController has been initialized. I can also see the following:
Creating instance of bean 'optimizerRulesController'
Initializing OptimizerRulesController
Mapped URL path [/optimizerRules] onto handler 'optimizerRulesController'
However, when I invoke my application using http://localhost:8080/appName/optimizerRules I get a 404 error!
What configuration am I missing here?
Thanks
Spring MVC would normally log that no mapping is found for a particular request at WARN level. Assuming you're not seeing that in your logs and assuming that WARN is enabled, and since you're not seeing your own log statement, it sounds like your request isn't even hitting the Spring MVC DispatcherServlet, which probably means the URL is wrong.
The URL should be http://server:port/war/dispatcherServletMapping/optimizerRules, so your web.xml should tell you the missing path component, if my assumptions are valid.
