如何在Dropwizard v1.1.0中使用UnitOfWorkAwareProxyFactory

问题描述

我需要在dropwizard中的资源外部调用DAO方法.看手册我不清楚如何使用它.手册说

  SessionDao dao = new SessionDao(hibernateBundle.getSessionFactory());ExampleAuthenticator exampleAuthenticator =新UnitOfWorkAwareProxyFactory(hibernateBundle).create(ExampleAuthenticator.class，SessionDao.class，dao); 

谁能告诉我调用DAO的 exampleAuthenticator 方法的用法.

感谢Kedar

解决方案

工作解决方案

 /**初始化代理dao以进行授权*/AuthenticatorDAOProxy authenticatorDAOProxy =新的UnitOfWorkAwareProxyFactory(hibernateBundle).create(AuthenticatorDAOProxy.class，DeviceDAO.class，deviceDAO); 

我们现在可以在球衣资源之外使用 authenticatorDAOProxy

需要注意的一件事， AuthenticatorDAOProxy 应该有一个接受 DeviceDAO

的构造函数.

现在您的proxyDao会变成

 公共类AuthenticatorDAOProxy {私有DeviceDAO deviceDAO;public AuthenticatorDAOProxy(DeviceDAO deviceDAO){this.deviceDAO = deviceDAO;}@UnitOfWorkpublic Boolean checkIsDeviceValid(String deviceId，User user){设备设备= deviceDAO.getByDeviceIdAndUser(deviceId，user);if(device！= null&&device.getIsActive()== true){返回true；}返回false；}} 

I need to call DAO methods outside resource in dropwizard.Looking at the manual Im unclear how to use it. The manual says

SessionDao dao = new SessionDao(hibernateBundle.getSessionFactory());
ExampleAuthenticator exampleAuthenticator = new
    UnitOfWorkAwareProxyFactory(hibernateBundle)
           .create(ExampleAuthenticator.class, SessionDao.class, dao);

Can anyone show me the usage of exampleAuthenticator methods which call DAO.

Thanks, Kedar

解决方案

Working solution

/** initializing proxy dao for authorization */
AuthenticatorDAOProxy authenticatorDAOProxy = new UnitOfWorkAwareProxyFactory(hibernateBundle)
            .create(AuthenticatorDAOProxy.class, DeviceDAO.class, deviceDAO);

We can now use authenticatorDAOProxy outside jersey resources

One thing to note., AuthenticatorDAOProxy should have a constructor accepting DeviceDAO

Now your proxyDao will look like

public class AuthenticatorDAOProxy {

  private DeviceDAO deviceDAO;

  public AuthenticatorDAOProxy(DeviceDAO deviceDAO) {
    this.deviceDAO = deviceDAO;
  }

  @UnitOfWork
  public Boolean checkIsDeviceValid(String deviceId, User user) {
    Device device = deviceDAO.getByDeviceIdAndUser(deviceId, user);
    if (device != null && device.getIsActive() == true) {
        return true;
    }
    return false;
  }
}
