如果出现下列错误

或者在ui-manger项目的pom.xml文件中

在spring-mvc.xml中加入名称空间
配置spring-mvc.xml
<?xml version="1.0" encoding="UTF-8"?> <!-- 配置自动扫描的包 -->
<context:component-scan base-package="com.component.handler"/>
<!-- 配置视图解析器 -->
<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">

如果有其他问题可能是jar包下载失败，可以将你的maven仓库删除重新下载，你也可以按alt+F5，选择项目更新，也可能是你的eclipse没有maven配置或者评论下方留言，如果有时间我可以帮你看看
伪静态效果
通过让DispatcherServlet映射*.html实现伪静态。可以将由SpringMVC处理的动态请求从表面看起来像是访问一个HTML静态页面，这样让项目不容易被猜到用什么技术实现的。
给黑客入侵制造障碍。
一定程度上有利于SEO优化：让搜索引擎更容易找到我们的网站。
我自己写好的项目，完整版的SSM整合reverse和parent父项目下有子项目，导入带有spring插件的eclipse时，子项目从父项目中导入就即可，注意有spring插件的eclipse要maven配置
我们做个首页展示
首页展示
创建index.jsp
可能报错，解决方案
在index.jsp中执行转发操作
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%
request.getRequestDispatcher("/index.html").forward(request, response);
%>
为/index.html地址映射一个handler方法
package com.component.handler;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
public class PortalMainHandler {
@RequestMapping("/index")
public String showIndexPage() {
//准备首页要显示的数据……
return "portal/main";
}
}
经过spring-mvc.xml的视图解析器拼接，我们创建main.jsp
页面自己写，现在直接
就可以看到自己的页面了
还可以将原型代码（前端人员写的）加入main.jsp中
但是加上base标签
<base href="http://${pageContext.request.serverName }:${pageContext.request.serverPort}${pageContext.request.contextPath}/"/>
注意点1：端口号和contextPath之间不要再加“/”。
注意点2：contextPath后面要加“/”。
样式加一下
