@PathVariable注解

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：、

@Controller
public class TestController {
@RequestMapping(value="/user/{userId}/roles/{roleId}",method = RequestMethod.GET)
public String 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)
public String getProduct(@PathVariable("productId") String productId){
System.out.println("Product Id : " + productId);
return "hello";
}
@RequestMapping(value="/javabeat/{regexp1:[a-z-]+}",
method = RequestMethod.GET)
public String getRegExp(@PathVariable("regexp1") String regexp1){
System.out.println("URI Part 1 : " + regexp1);
return "hello";
}
}
