因为用了Springmvc 做请求控制 所以首页<welcome-file-list>配置信息放在Springmvc配置的上面

JDBC的配置

DAO实现类

service实现类

最后controller
package cn.springmvc.controller;
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import cn.springmvc.model.User;
import cn.springmvc.service.UserService;
@Controller
@RequestMapping("/home")
public class UserController {
@Autowired
private UserService userService;
@RequestMapping("/user")
public String index(Model model){
List<User> findAllUser = userService.findAllUser();
model.addAttribute("UserAll",findAllUser);
return "index";
}
}
访问
最后配置通过域名或者IP直接访问项目
tomcat conf-->server.xml配置修改
<Connector connectionTimeout="20000" port="80" protocol="HTTP/1.1" redirectPort="8443"/>
在<host><host>中间 加上
<Context path="" docBase="项目名（就是部署到webapps下面的名字）" debug="0"/>
上面项目已经设置首页了 直接输入localhost或者IP或者你申请的域名直接访问项目。
