Missing part of string from Spring PathVariable mapping

[sam White]

Hi with spring mvc 3.0.5 and jsp, I use Spring PathVariable to pass an {id} to controller, where {id} is an email address.
After the id has been passed into the controller, the tailing .au of the email address is missing.

Here is the log messages:

01:26:59,834 DEBUG [org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping] (http--192.168.1.20-8080-6) URI Template variables for request [/admin/thumbnail/samuel@morf eusflex.com.au] are {id=[e-mail]} 01:26:59,835 DEBUG [org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping] (http--192.168.1.20-8080-6) Mapping [/admin/thumbnail/[e-mail]] to HandlerE xecutionChain with handler [deliveries.manager.controller.DeliveriesController@658b0b44] and 3 interceptors 01:26:59,839 DEBUG [org.springframework.web.servlet.DispatcherServlet] (http--192.168.1.20-8080-6) Last-Modified value for [/DeliveriesManager-web/deliveries/admin/thumbnail/samuel@morfeusflex .com.au] is: -1 01:26:59,844 DEBUG [org.springframework.core.convert.support.GenericConversionService] (http--192.168.1.20-8080-6) Converting value '[e-mail]' of java.lang.String to @org.springf ramework.web.bind.annotation.PathVariable java.lang.String 01:26:59,845 DEBUG [org.springframework.core.convert.support.GenericConversionService] (http--192.168.1.20-8080-6) Converted to '[e-mail]' 01:26:59,846 DEBUG [org.springframework.web.bind.annotation.support.HandlerMethodInvoker] (http--192.168.1.20-8080-6) Invoking request handler method: public org.springframework.http.ResponseE ntity deliveries.manager.controller.DeliveriesController.showThumbnail(java.lang.String,org.springframework.ui.ModelMap) throws java.lang.Exception 01:26:59,847 DEBUG [deliveries.manager.controller.DeliveriesController] (http--192.168.1.20-8080-6) ====showThumbnail, loginName: [e-mail]

In the above log message, I am passing in email address [e-mail] as the {id}, but ".au" is missing from its mapping.

here is my jsp file:

<spring:url value="admin/thumbnail/${pageContext.request.userPrincipal.name}" var="url" htmlEscape="true" /> <img alt="" src="${url}" />

controller class:

@RequestMapping(value = "admin/thumbnail/{id}", method = RequestMethod.GET)
    public ResponseEntity<byte[]> showThumbnail(
                                    @PathVariable("id") String id,
                                    ModelMap model) throws Exception {
        logger.debug("====showThumbnail, loginName: "+id);


        if ( StringUtils.isEmpty(id)) {
             throw new RuntimeException("loginName is null");
        }
        
        Admin admin = adminService.findAdminByLoginName(id);
        if (admin.getImageData() == null) {
            throw new RuntimeException("ImageData is null");
        }

What is wrong with the spring mapping in my example?

Any suggestion is very appreciated.
Thanks

Yes, there are some characters that end up making it the end of that pathVariable even though there might be more text in it. So you have to break it into more than one pathVariable and then concatenate the Strings adding the character that caused the problem

In your email example that would be the "."

so I recomment

myApp/{firstPart}.{lastPart}

public String someMethod(@PathVariable("firstPart") String first, @PathVariable("secondPart") String second) {

String email = first + "." + second;

}
