[英]HTTP Server Status 404 Error in Spring MVC Project
我正在遵循與此404 錯誤相同的教程- Java Spring MVC using Maven in Eclipse from Tutorial填寫表格后,我收到 404 錯誤

@Controller

源項目
那么如何在填寫表單后成功獲得“display.jsp”頁面。
您在 telusko-servlet.xml 中缺少 InternalResourceViewResolver bean
<!-- Define Spring MVC view resolver -->
<bean
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/view/" />
<property name="suffix" value=".jsp" />
</bean>
將您的 jsp 頁面放在 WEB-INF/view 文件夾中而不是在它之外也是一種很好的做法。 添加該 bean 后,您不會返回 display.jsp
你的控制器方法應該看起來像
@RequestMapping("/add")
public String add() {
return "display";
}
此外,避免在您的 bean xml 中使用版本也是明智之舉,如果上述方法無助於嘗試使用類似
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:tx="http://www.springframework.org/schema/tx"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc.xsd
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx.xsd">
您可以像這樣調用“/addController/add”
@Controller
@RequestMapping("/addController ")
public class AddController {
@RequestMapping("/add")
public String add() {
return "display";
}
}
