如何创建一个多项目spring mvc（带前端和后端项目）

标签： spring spring-mvc multi-project

我是spring mvc的新手，我想用maven创建一个多项目应用程序，使用angularjs和requirejs创建一个项目前端（css，javascript和html），以及一个带有spring mvc的后端项目，可以访问mongodb数据库，例如在我的前端项目中，我做了一个如下调用：

$http.post('login/makeLogin', $scope.user)
            .success(function(data) {
                               ....
                         }

然后使用一个映射此请求的LoginController进入我的后端项目：

@Controller
@RequestMapping(value="/login")
public class LoginController {

    @Autowired
    private UserService userService;

    @RequestMapping(value="/makeLogin", method=RequestMethod.POST)
    public @ResponseBody User makeLogin(@RequestBody User user){
        System.out.println("login");
        User userlogin = userService.login(user.getLogin(), user.getPassword());

        return userlogin;
    }
}

我不知道如何以spring mvc方式执行此操作，我使用spring mvc分别测试每个项目，每个项目都有效，目前我使用maven添加后端项目作为前端的依赖项，创建一个包含所有clases的唯一war文件，然后我从前端servlet-context中的后端导入servlet-context：

    <annotation-driven />

    <!-- Handles HTTP GET requests for /resources/** by efficiently serving up static resources in the ${webappRoot}/resources directory -->
    <resources mapping="/resources/**" location="/resources/" />


    <beans:import resource="classpath*:backend-context.xml"/>
    <context:annotation-config />

    <context:component-scan base-package="com.siellano.frontend" />
    <context:component-scan base-package="com.siellano.backend" />
在我的后端上下文中的

是使用mongodb和spring mvc的所有配置，但是当服务器部署前端项目时，这会引发异常：

现在，我是如何实现这一点的，或者我做错了什么，或者这可以用spring mvc吗？

userService 

@Service
public class UserService {

    @Autowired
    UserRepository userRepository;

    public User login(String username,String password){

        User user = userRepository.findByLoginAndPassword(username, password);

        return user;
    }
}

我发布了我的userService，并告诉我的应用程序现在可以工作，但我想知道有多少方法可用于此，哪个更好（例如我阅读有关maven模块），它在我添加后端上下文时有效我的前端web.xml中的-xml
