spring mvc中的@PathVariable是用来获得请求url中的动态参数的，十分方便，复习下：
代码如下@Controller
publicclassTestController {
@RequestMapping(value="/user/{userId}/roles/{roleId}",method = RequestMethod.GET)
publicString getLogin(@PathVariable("userId") String userId,
@PathVariable("roleId") String roleId){
System.out.println("User Id : "+ userId);
System.out.println("Role Id : "+ roleId);
return"hello";
}
@RequestMapping(value="/product/{productId}",method = RequestMethod.GET)
publicString getProduct(@PathVariable("productId") String productId){
System.out.println("Product Id : "+ productId);
return"hello";
}
@RequestMapping(value="/javabeat/{regexp1:[a-z-]+}",
method = RequestMethod.GET)
publicString getRegExp(@PathVariable("regexp1") String regexp1){
System.out.println("URI Part 1 : "+ regexp1);
return"hello";
}
}
