Java 正在尝试将Spring应用程序部署到Tomcat

我正在尝试制作一个简单的SpringWeb应用程序。我用mvn包制作war文件。当e将文件部署到Tomcat时，它会给我一个无法修复的异常。我将把我所有的代码复制到这里。我希望有人能帮助我修复我的项目

HelloController.java

    package com.nikola.hellocontroller;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;



import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.AbstractController;


public class HelloController extends AbstractController {

    @Override
    protected ModelAndView handleRequestInternal(HttpServletRequest arg0, HttpServletResponse arg1)
            throws Exception {
        ModelAndView modelandview = new ModelAndView("HelloPage");
        modelandview.addObject("welcomeMessage", "Good Day.");

        return modelandview;
    }
}

我认为spring-dispatcher-servlet.xml中的Bean配置是错误的。该类的软件包是错误的。使用以下命令：

<?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-3.0.xsd">

    <bean id="HandlerMappping"
          class="org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping" />

    <bean name="/welcome.html" class="com.nikola.hellocontroller.HelloController" />


    <bean id="viewResolver"
          class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix">

也可以尝试删除弹簧腹板套的4.1.1。 我认为可能存在版本冲突

或运行 清洁包装 并查看目标目录中的WEB-INF/lib

---

您应该看到spring-webmvc-4.1.1.jar

还有另一个错误的包。已完成版本：）我做了所有更改。现在没有例外，但当我部署war文件并在这个url上打开它时，会出现以下错误消息：HTTP Status 404-type Status report message description请求的资源不可用。Apache Tomcat/7.0.56创建的war文件的名称是什么？似乎/NENOV上下文名称是错误的。根据war文件确定其大小写。我还认为您需要在web.xml中添加spring侦听器来初始化spring：org.springframework.web.context.ContextLoaderListener我已经解决了我的问题。正确的url是localhost:8080/NENOV/welcome.html
