SpringMVC----@RequestMapping_PathVariable映射URL绑定的占位符 _RequestMapping

君不见长松卧壑困风霜，时来屹立扶明堂。这篇文章主要讲述SpringMVC----@RequestMapping_PathVariable映射URL绑定的占位符相关的知识，希望能为你提供帮助。
1.概述
带占位符的URL是spring3.0新增的功能，该功能在SpringMVC向REST目标挺进发展过程中具有里程碑的意义；
通过@PathVariable可以将URL中占位符参数绑定到控制器处理方法的入参中：URL中的{xxx}占位符可以通过@PathVariable("xxx")绑定到操作方法的入参中；
2.代码

测试类：package com.yk.springmvc.handlers; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.PathVariable; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; @RequestMapping("/springmvc") @Controller public class SpringMVCTest {private static final String SUCCESS = "success"; @RequestMapping("/testPathVariable/{id}") public String testPathVariable(@PathVariable(value=https://www.songbingjia.com/android/("id")) Integer id){ System.out.println("SpringMVCTest.testPathVariable()"+id); return SUCCESS; }@RequestMapping("/testAntPath/*/abc") public String testAntPath(){ System.out.println("SpringMVCTest.testAntPath()"); return SUCCESS; }/** * 可以使用params和headers来更加精确映射请求，params和headers支持简单的表达式 * @return */ @RequestMapping(value="https://www.songbingjia.com/android/testParamsAndHeaders",params={"username","age!=10"}/*,headers={"Accept-Language:zh-CN,zh; q=0.9"}*/) public String testParamsAndHeaders(){ System.out.println("SpringMVCTest.testParamsAndHeaders()"); return SUCCESS; }/** * 使用method属性指定请求方式 * @return */ @RequestMapping(value="https://www.songbingjia.com/testMethod",method=RequestMethod.POST) public String testMethod(){ System.out.println("SpringMVCTest.testMethod()"); return SUCCESS; }@RequestMapping("/testRequestMapping") public String testRequestMapping(){ System.out.println("SpringMVCTest.testRequestMapping()"); //return "success"; 下面会有很多，所以定义一个常量 return SUCCESS; } }index.jsp< a href="https://www.songbingjia.com/android/springmvc/testPathVariable/1"> testPathVariable< /a> 结果返回：SpringMVCTest.testPathVariable()1 SpringMVCTest.testPathVariable()100000 SpringMVCTest.testPathVariable()100000 SpringMVCTest.testPathVariable()15555
