达迪奇

如果控制器返回到“hello1”，那么视图中只需要hello1.jsp，值是RequestMapping值的名称，那么是否有“单击”主题之一

若控制器返回到“hello1”，那个么视图中只需要hello1.jsp，并且值是RequestMapping值的名称，所以是否有“单击”主题之一

使用
addAttribute
而不是
put
放入
控制器中


  map.addAttribute("helloMessage", helloWorldMessage);  
  map.addAttribute("welcomeMessage", welcomeMessage);  


别忘了在jsp中启用EL。使用此代码启用它


<%@ page isELIgnored="false" %>



使用
添加属性
而不是
将
放入
控制器
中


  map.addAttribute("helloMessage", helloWorldMessage);  
  map.addAttribute("welcomeMessage", welcomeMessage);  


别忘了在jsp中启用EL。使用此代码启用它


<%@ page isELIgnored="false" %>
