Java 警告：在名为'；调度员'；

我刚刚开始实现简单的SpringRESTAPI应用程序。我的web.xml文件如下所示

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://java.sun.com/xml/ns/javaee"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
id="WebApp_ID" version="3.0">


<display-name>Archetype Created Web Application</display-name>

<servlet>
    <servlet-name>dispatcher</servlet-name>
    <servlet-class>
        org.springframework.web.servlet.DispatcherServlet
    </servlet-class>
    <load-on-startup>1</load-on-startup>
</servlet>

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

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>/WEB-INF/dispatcher-servlet.xml</param-value>
</context-param>

<listener>
    <listener-class>
        org.springframework.web.context.ContextLoaderListener
    </listener-class>
</listener>

然后我在tomcat服务器中部署了它，并尝试访问它

然后，我的控制台日志中出现以下错误

WARNING: No mapping found for HTTP request with URI [/SpringRestServer/suntravel] in DispatcherServlet with name 'dispatcher'

项目结构

任何帮助都将不胜感激

谢谢

您需要在应用程序上下文配置中解开

元素。这将注册bean来处理带注释的控制器

<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"

<mvc:annotation-driven/>

<bean

    <property name="prefix">
        <value>/WEB-INF/</value>
    </property>
    <property name="suffix">
        <value>.jsp</value>
    </property>
</bean>

尝试使用dispatcher-servlet.xml

web inf中是否有Bob.jsp？如果是这样，我想你的意思是你的url在这里使用Bob作为请求的参数你在web inf中有任何.jsp文件吗？是的，idex，jsp。如果我尝试加载index.jsp页面，请复制index.jsp，将其命名为blah.jsp，并对其进行一些修改，这样您就可以区分index和blah之间的区别。然后启动您的服务器，将浏览器指向，并让我知道您是否看到blah.jsp。什么是mvc：注释驱动元素？那么dispatcher servletmy bad会发生什么情况！！这是新的dispatcher-servlet.xml。更新了PostTry。但同样的警告也出现在MVC项目中。试图保持文件名与您的相同：。

 http://localhost:8080/SpringRestServer/suntravel?Bob    < wrong
 http://localhost:8080/SpringRestServer/suntravel/Bob    < right
