springMVC——匹配URL路径执行指定控制层

springMVC中可以将指定URL模式地址肯指定访问Controller的路径进行关联与匹配，如果某一个访问Controller控制层的UTL与该URL模式进行匹配，则调用匹配的Controller控制层

controller中的url路径如下，访问时我们只需匹配格式就能完成访问

@RequestMapping("/hello/{userId}")
@PathVariable 或者 @PathVariable("userId")

@RequestMapping("/hello3/{userId}/age/{ageValue}")
@PathVariable

 

项目实例如下

test

package controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class URLMatchTest {

	// 直接使用配置变量
	@RequestMapping("/hello/{userId}")
	public String test1(@PathVariable String userId) {
		System.out.println("run test1 userId=" + userId);
		return "/index.jsp";
	}

	// 对配置变量进行另起别名为userIdParam
	@RequestMapping("/hello2/{userId}")
	public String test2(@PathVariable("userId") String userIdParam) {
		System.out.println("run test2 userIdParam=" + userIdParam);
		return "/index.jsp";
	}

	@RequestMapping("/hello3/{userId}/age/{ageValue}")
	public String test3(@PathVariable String userId, @PathVariable int ageValue) {
		System.out.println("run test3 userId=" + userId + " ageValue="
				+ ageValue);
		return "/index.jsp";
	}
}

test2

package controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
@RequestMapping("/hello4/{userId}")
public class URLMatchTest2 {
	@RequestMapping("/age/{ageValue}")
	public String test100(@PathVariable String userId,
			@PathVariable int ageValue) {
		System.out.println("run test100 userId=" + userId + " ageValue="
				+ ageValue);
		return "/index.jsp";
	}
}
