idea 创建redis idea创建ssm项目

 

前言

博客描述：

本内容是基于idea和maven的一个SSM项目搭建的demo。创建项目时，记得联网（很重要）。

首先需要确定你的idea的maven，java环境是否正常。如下：

1 、创建项目

 

在上一步，点击Finish。完成创建。

2、完善目录结构

操作：选中main文件夹，创建Directory。并标记为相应的文件夹类型。

 

第一步：创建文件夹（目录）

选中main文件夹，使用快捷键（alt + inseert），使用键盘上、下键选中Dieectory。点击创建（名字分别是java、resources、test）。

第二步：标记指定的目录类型

标记成功时：发现头标，颜色发生了变化。

第三步：配置mysql数据库（可以不配）

本人建议，配置上，因为很好用，可以当做Nativcat来用，而且提示很多。（谁用谁知道）

 

到这里，如果测试成功，那恭喜你，配置好了。Apply -> ok 就可以去使用了。

第四步：pom.xml文件

        return "User{" +
                "id=" + id +
                ", name='" + name + '\'' +
                ", password='" + password + '\'' +
                ", birthday=" + birthday +

@Service
public class UserServiceImpl implements UserService {

    @Autowired

@Controller
public class UserController {

    @Autowired
    private UserService userService;

    @RequestMapping("index.action")
    public String toIndex(HttpServletRequest request){
        request.getSession().setAttribute("userList", userService.userList());
        return "index";
    }
}

第7步：resources中的配置文件
