我使用IntelliJ生成Spring MVC应用程序,并使用Spring 4.0.5.RELEASE进行此学习。我按照了一本书的教程,认为我按照书中所说的那样配置了所有内容,但我一直得到令人沮丧的404错误。我发布了我的src / main / webapp / WEB-INF / web.xml内容,如下所示:
<web-app version="2.4"

我的mvc-dispatcher-servlet.xml内容是:
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc"

<context:component-scan base-package="com.rcholic.news"/>
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/pages/"/>
<property name="suffix" value=".jsp"/>
</bean>
</beans>
我的applicationContext.xml几乎为空:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
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">
</beans>
我的控制器是:
@Controller
public class HomeController {
@RequestMapping(value = "/hello", method = RequestMethod.GET)
public String printWelcome(ModelMap model) {
model.addAttribute("message", "Hello world!");
return "pages/hello";
}
}
答案 0 :(得分:4)
您尚未使用
在mvc-dispatcher-servlet.xml
中启用MVC堆栈
<mvc:annotation-driven />
因此没有注册任何@Controller
处理程序方法。
请记住添加适当的mvc
命名空间声明。
请注意您当前的InternalResourceViewResolver
,其中包含
<property name="prefix" value="/WEB-INF/pages/"/>
<property name="suffix" value=".jsp"/>
以及处理程序方法返回的视图名称
return "pages/hello";
资源将在
中查找/WEB-INF/pages/pages/hello.jsp
这对我来说似乎不对。
