Java apache中没有错误，但我得到一个404错误,java,spring,spring-mvc,Java,Spring,Spring Mvc,我已经做了一天了，不明白为什么它不起作用。我遵循了一个教程，阅读了spring文档，仍然不理解，更好的是还有一些错误要处理 Mar 19, 2015 6:42:04 PM org.apache.tomcat.util.digester.SetPropertiesRule begin WARNING: [SetPropertiesRule]{Server/Service/Engine/Host/Context} Setting property 'source' to 'org.eclip

你好，来自JSP的世界。。。

提供servlet.xml

        <property
            name="suffix"
            value=".jsp"></property>
    </bean>
</beans>

最后说明：

使用SpringWebMVCjar。checkpom.xml您所需要的就是这个
添加到offers-servlet.xml。请查看以下注释以了解更多信息 -不要在eclipse中使用run-on-server并从浏览器请求

package com.learnspring.controller;

import javax.servlet.http.HttpServletRequest;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.ModelAndView;

@Controller
@RequestMapping(value = "/")
public class OffersController {
    @RequestMapping(method = RequestMethod.GET)
    public ModelAndView homeGet(HttpServletRequest request) {
        System.out.println("Check mapping");
        ModelAndView model = new ModelAndView("home");
        return model;
    }
}

重写“/”Servlet映射的警告是必须按名称检索默认Servlet的RequestDispatcher 而不是通过路径。DefaultServletHttpRequestHandler将尝试要在启动时自动检测容器的默认Servlet，使用大多数主要Servlet容器的已知名称列表（包括Tomcat、Jetty、GlassFish、JBoss、Resin、WebLogic和 WebSphere）

您试图访问哪个url？你在听哪个教程？显示完整的stacktrace和你要点击的url.caveofprograming.com我买了一系列视频来帮助自己学习spring。堆栈跟踪是，如果有必要的话，我使用的是apache 8.0。部署在tomcat中的war文件的名称是什么？我的控制器名称（servlet）命名为offers-servlet.xml我在servlet下的web.xml文件中的显示名称命名为“offers”，servlet类为org.springframework.web.servlet.DispatcherServlet。因此，我遵循的默认规则正确吗？@jocdrew21确定请将侦听器添加到您的web。xml@jocdrew21Can请您向这个url localhost:8080/JavaSpringMVCTake2/发出请求，我意识到您在请求时忘记了/。这是一个剪切粘贴错误，是的，我正在使用localhost:8080/JavaSpringMVCTake2/这太令人沮丧了。。。谢谢你的帮助。不客气，它能解决你的问题吗？你现在能看到home.jsp吗？
