spring mvc: 属性方法名称解析器(多动作控制器)MultiActionController/ControllerClassNameHandlerMapping/PropertiesMethodNameResolver
spring mvc: 属性方法名称解析器(多动作控制器)
加入控制器是StudentContrller.java,里面有3个方法 index,add,remove
那么访问地址是:
http://localhost:8080/项目名/student/index.html
http://localhost:8080/项目名/student/add.html
http://localhost:8080/项目名/student/remove.html
需要用到的配置类方法:
org.springframework.web.servlet.mvc.support.ControllerClassNameHandlerMapping
org.springframework.web.servlet.mvc.multiaction.PropertiesMethodNameResolver
控制器用到的类:
org.springframework.web.servlet.mvc.multiaction.MultiActionController
配置文件web.xml, xxxx-servlet.xml,applicationContext.xml
