这些jar包最好是下载好了的,因为没有使用meaven创建项目

根项目创建resources文件夹

在src创建你需要的文件

准备一个页面,测试项目是否创建成功

准备Controller

@Controller
@RequestMapping("/department")
public class DepartmentController {
    @Autowired
    private IDepartmentService departmentService;

    @RequestMapping("/index")
    public String index(){
        return "index";
    }

    @RequestMapping("/list")
    @ResponseBody
    public List<Department> list(){
        return departmentService.findAll();
    }
}

输入路径测试
http://localhost/department/index


有些问题我很难跟你解释,你能懂吗

小结:这个是spring+springMVC+mybatis的普通web项目集成,项目搭建没有使用meaven结构创建,目的就是为了使我们更加清楚整个项目的结构,在使用meaven搭建的时候更加清晰那部分是做什么的,就暂时写这些
