控制器類映射

Question

org.springframework.web.servlet.PageNotFound noHandlerFound

我沒能找到下面的代碼中的錯誤，因爲我剛剛學習Spring MVC的。 無法在控制器類中映射請求，並嘗試檢查配置文件但無法找到錯誤。請幫助我完成該計劃。

的web.xml

<!DOCTYPE web-app PUBLIC

<servlet> 
    <servlet-name>telusko</servlet-name> 
    <servlet-class> 
    org.springframework.web.servlet.DispatcherServlet 
    </servlet-class> 
</servlet> 

<servlet-mapping> 
    <servlet-name>telusko</servlet-name> 
    <url-pattern>/</url-pattern> 
</servlet-mapping> 

telusko-servlet.xml中

<beans xmlns="http://www.springframework.org/schema/beans"

Controller類

package com.telusko; 
import org.springframework.stereotype.Controller; 
import org.springframework.web.bind.annotation.RequestMapping; 
@Controller 
public class AddController { 

@RequestMapping("/add") 
public void add(){ 
System.out.print("hi"); 
} 

} 

ErrorResult

WARNING: No mapping found for HTTP request with URI [/teludkospringmvc/add] 
in DispatcherServlet with name 'telusko' 

Answer 1

我認爲你缺少你telusko-servlet.xml文件這一行，使Spring MVC的註解：

<mvc:annotation-driven/> 

希望工程。

Answer 2

更新：在添加<mvc:annotation-driven/>後按照mlg的建議。

你還在懷念內部reourse他們找不到你display.jsp

telusko-servlet.xml中

<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> 
    <property name="prefix"> 
    <value>/WEB-INF/</value> 
    </property> 
    <property name="suffix"> 
    <value>.jsp</value> 
    </property> 
</bean> 

AddController.java

@Controller 
public class AddController { 

    @RequestMapping("/add") 
    public String add(){ 
     return "display"; 
    } 

}
