spring mvc中的@PathVariable

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：

Java代码


@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";

}

}
