调用引用项目类方法时java.lang.ClassNotFoundException

我创建了一个spring restful动态web项目，并将其添加为第二个spring restful动态web项目中的引用，但在调用引用项目方法时出现了java.lang.ClassNotFoundException。我已将引用项目包括在类路径中以及部署程序集中。 这是代码

@RestController
@RequestMapping("/get")
public class GetController {

@GetMapping("/admin")
public ArrayList<Admin> get(){
    ArrayList<Admin> admins = new ArrayList<Admin>();
    AdminDao adminDao = new AdminDao(); // this is reference project object
    ArrayList<com.model.Admin> adminModel = new ArrayList<com.model.Admin(); // this is reference project Admin object
    adminModel = adminDao.getAllAdmin();
    for(int i=0; i<adminModel.size(); i++){
        admins.get(i).setAddress(adminModel.get(i).getAddress());
        admins.get(i).setAge(adminModel.get(i).getAge());
        admins.get(i).setEmail(adminModel.get(i).getEmail());
        admins.get(i).setId(adminModel.get(i).getId());
        admins.get(i).setName(adminModel.get(i).getName());
        admins.get(i).setPassword(adminModel.get(i).getPassword());
    }
    return admins;
}

告诉我我犯了什么错误。

谢谢。

请添加项目结构。我不明白什么是“SpringRESTfulDynamicWeb项目，并在第二个SpringRESTfulDynamicWeb项目中添加作为引用”。您是如何在服务器上的IDER上测试此功能的？@SauliusNext我添加了structureAdd package explorer视图。如果你喜欢混合项目，我建议将常用部分转移到单独的java项目中。@SauliusNext我添加了包explorer请阅读本文，我希望这将引导你找到正确的方法
