以下是：

appServlet-servlet.xml中

<?xml version="1.0" encoding="UTF-8"?>

    <!-- DispatcherServlet Context: defines this servlet's request-processing

</beans:beans>

的web.xml

<?xml version="1.0" encoding="UTF-8"?>

<web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" >




<servlet>
        <servlet-name>appServlet</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
        </servlet>
<servlet-mapping>
<servlet-name>appServlet</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>




</web-app>

HelloController.java

@Controller
@RequestMapping("/welcome")
public class HelloController  {

    @RequestMapping("/hello")
    public ModelAndView helloWorld(HttpServletRequest arg0,
            HttpServletResponse arg1) throws Exception {
        return new ModelAndView("/HelloWorld.jsp");
    }

}

在DispatcherServlet中找不到带有URI [/ HelloWorld / welcome / hello]的HTTP请求的映射，名称为＆＃39; appServlet＆＃39; 我正在使用spring 3.2.0如果添加了所有必需的jar文件。我正在使用没有maven。请尝试帮助我

Answer 1

来自春季参考文档：

DispatcherServlet是一个实际的Servlet（它继承自HttpServlet基类），因此在Web应用程序的web.xml中声明。您需要使用同一web.xml文件中的URL映射来映射您希望DispatcherServlet处理的请求。这是标准的Java EE Servlet配置;以下示例显示了这样的DispatcherServlet声明和映射：

<web-app>
<servlet>
    <servlet-name>example</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
    <servlet-name>example</servlet-name>
    <url-pattern>/example/*</url-pattern>
</servlet-mapping>
</web-app>

在前面的示例中，所有以/ example开头的请求都将由 DispatcherServlet实例名为example。

Answer 2

从您的URI中删除HelloWorld并尝试通过/ welcome / hello访问

春天3.2.0没有发现uri
