Spring MVC URI Template Patterns using Regular Expressions

In the previous example you have seen " How to map URLs using annotations". In this example you can see how to use regular expressions as part of URI.

The @RequestMapping annotations supports the use of regex in URI template variables. The syntax is {varName:regex} where the first part defines the variable name and the second is the regular expression.

The following example shows a controller in a Spring MVC application that uses @RequestMapping annotation with regex support:

@RequestMapping(value = "/java/{libName:[a-zA-Z\\-]+}-{version:\\d\\.\\d\\.\\d}", 
			method = RequestMethod.GET)
public void handleDownloads(@PathVariable String libName, @PathVariable String version){
		
	System.out.println("libName: "+libName);
	System.out.println("version: "+version);
	
	// your business logic
}
