测试开发进阶——spring boot——MVC——@RequestMapping 是一个用来处理请求地址映射的注解,可用于类或方法上

@RequestMapping 是一个用来处理请求地址映射的注解,可用于类或方法上。
用于类上,表示类中的所有响应请求的方法都是以该地址作为父路径;
用于方法上,表示在类的父路径下追加方法上注解中的地址将会访问到该方法,此处需注意@RequestMapping用在类上可以没用,但是用在方法上必须有。
=======================================================================
用在类和方法上:
package com.awaimai.web; import org.hibernate.validator.constraints.*; import org.springframework.stereotype.Controller; import org.springframework.validation.BindingResult; import org.springframework.validation.annotation.Validated; import org.springframework.web.bind.annotation.*; import javax.servlet.http.Cookie; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import javax.validation.Valid; import javax.validation.constraints.Max; import javax.validation.constraints.Min; import javax.validation.constraints.Size; import java.util.Enumeration; @Controller @Validated @RequestMapping(value = "/abc") public class kzq { @RequestMapping(value = "/test6") @ResponseBody public String test6() { return "123"; } }
