如果我有线
<context:component-scan base-package="uni.inso" />
<mvc:annotation-driven />
在我的dispatcher-servlet.xml中,我将从我的tomcat中收到此错误消息:
WARN "http-bio-8080"-exec-1 servlet.PageNotFound:1108 - No mapping found for HTTP request with URI [/inso/home] in DispatcherServlet with name 'dispatcher'
但是,如果我在我的web-application-config中有这两行,它可以正常工作。 此外,InternalViewResolver不会在dispatcher-servlet-xml中工作,但在web-application-config中也可以。 为什么会这样?
我得到了以下web.xml
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

也许你真的想在你的web.xml中做这样的事情:
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/web-application-config.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<servlet>
<servlet-name>dispatcher</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/dispatcher-servlet.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>

我认为你没有在你的包中定义任何控制器servlet,因此它无法为任何URL找到任何类型的映射。
@Controller
public class HelloController{
@RequestMapping(value = "/hello", method = RequestMethod.GET)
public String printHello(ModelMap model) {
model.addAttribute("message", "Hello Spring MVC Framework!");
return "hello";
}
}
您也可以参考此Tutorial。
