tuscany can't support generic interface perfect
-----------------------------------------------
Key: TUSCANY-3926
URL: https://issues.apache.org/jira/browse/TUSCANY-3926
Project: Tuscany
Issue Type: Bug
Components: Java SCA Assembly Model
Affects Versions: Java-SCA-1.6.2
Environment: tuscany 1.6.x
Reporter: fzhong
I created a generic interface as an component interface,I got an error when i
called the generic method exposed by the component service.See more details as
follows:
1.generic interface
public interface OtaService<T> {
/**
* 根据id获取对象
* */
public T get(Long id);
/**
*
* */
public List<T> queryList(T t,boolean fuzzy);
/**
* 根据id获取对象
* */
public List<T> getList(Long...id);
/**
* 根据id删除对象
* */
public void del(Long...id);
/**
* 新增对象
* */
public Long insert(T t);
/**
* 更新对象
* */
public void update(T t);
}
2.@Remotable
public interface UserService extends OtaService<User>{
/**
* 校验用户名密码,通过返回用户ID，其他返回null
* */
public Long checkUserPassword(String username,String password);
/**
* 根据角色获取用户列表
* */
public List<User> getUserByRole(Long... roleId);
/**
* 根据授权获取用户列表
* */
public List<User> getUserByAuthority(Long... authorityId);
/**
* 根据资源获取用户列表
* */
public List<User> getUserByResource(Long... resourceId);
}
UserService is an remotable interface ,that extends the OtaService interface.
3.UserServiceImpl implemented UserService interface.You can get it from
attachment;
When I called the method that's parameter types are generic,such as
queryList(T t,boolean fuzzy), insert(T t),update(T t),it threw exceptions.
