使用Spring Boot外部化mongo json查询

Question

我刚刚开始使用Spring-Boot的spring data MongoDb。

我主要想要实现的是将上面的本机mongo json查询外部化到配置文件中，并在上面的注释中引用它。

在Hibernate中使用jpa时，Spring数据支持类似的内容。但不确定我们是否可以使用spring data mongodb和spring Boot来做同样的事情。

像这样做（我只是为API解释）

假设您有一个实体用户

在顶部将有用户域

public class User extends CoreDomain {
private static final long serialVersionUID = -4292195532570879677L;
@Length(min = 2)
private String name;
@Length(min = 2)
@UniqueUserName(message = "User name already registered,Please choose something Different")
private String userName;
@Length(min = 6)
private String password;
}

public class UserController extends CoreController {

@Autowired
private UserService userService;

/*
 * This controller is for getting the UserDetails on passing the UserId in
 * the @param Annotation
 */
@GET
@Path("{id}")
public User getUser(@PathParam("id") String UserId) {
    User user = new User();
    user = userService.findUserId(UserId);

    if (user == null)
        throw new NotFoundException();
    log.info("The userId you searched is having the details as :" + user);
    return user;
}}

public interface UserService {
// Boolean authenticateUser(User user);

User findUserId(String UserId);

}

public class UserServiceImpl implements UserService {
@Setter
@Autowired
private UserRepository userRepository;

/*
 * This method will find user on the basis of their userIds passed in the
 * parameter.
 */
@Override
public User findUserId(String UserId) {
    User userIdResult = userRepository.findOne(UserId);
    log.info("The userDetail is" + userIdResult);
    return userIdResult;
}

在针对user的mongoRepository中，我们将有：一个默认查询findbyid（String userId）；

希望这能帮助你。
