整晚我試圖找到問題,但沒有找到問題。 修改了此問題的現有主題,但沒有任何幫助。 我改變<url-pattern>/*</url-pattern> 方式<context:component-scan base-package="com.xemyl.simplexonline" /> ,並加入到@Controller - >( 「/」)在名爲'appServlet'的DispatcherServlet中使用URI [/ simplexonline /]發現HTTP請求沒有映射

我猜,你就得MVC命名空間

嘗試,

<?xml version="1.0" encoding="UTF-8"?> 
<beans xmlns="http://www.springframework.org/schema/beans" 
    xmlns:mvc="http://www.springframework.org/schema/mvc" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xsi:schemaLocation=" 
     http://www.springframework.org/schema/beans 
     http://www.springframework.org/schema/beans/spring-beans.xsd 
     http://www.springframework.org/schema/mvc 
     http://www.springframework.org/schema/mvc/spring-mvc.xsd"> 

<mvc:annotation-driven/> 

..... 

</beans> 

@Controller( 「/」)

到@Controller
