Question

Springmvc RequestMapping里的name参数是做什么用的

Answer 1

RequestMapping似乎没有name参数吧，它是用来替代HandleMapping的，一般用于连接浏览器与服务器之间的路径，如@RequestMapping("/login.do")
有name参数的是Resource,像@Resource(name = "loginService")
这里的name参数是告诉服务器去读取有注解@Service("loginService")的class

Answer 2

抱歉，压根没听说name属性，常用value

Answer 3

引用破薇九夜歌的回答：
抱歉，压根没听说name属性，常用value

/**
* Assign a name to this mapping.
* <p><b>Supported at the type level as well as at the method level!</b>
* When used on both levels, a combined name is derived by concatenation
* with "#" as separator.
* @see org.springframework.web.servlet.mvc.method.annotation.MvcUriComponentsBuilder
* @see org.springframework.web.servlet.handler.HandlerMethodMappingNamingStrategy
*/
String name() default "";
源代码上面的注释，name的作用就是一个命名
