Entityframework usage (6) static repository

In the previous article, we introduced unity to help build various repository and unitofwork.

At the same time, we inject unitycontainer into the implementation of servicelocator,

 
1Unityservicelocator locator =NewUnityservicelocator (container );2Servicelocator. setlocatorprovider () => Locator );
 

If the number of tables is too large, it is too cumbersome to inject ixxxrepository into the service class. To find a concise method, we will introduce servicelocator and static classes here, although both methods are not suitable for unit testing.

 1     Public   Static   Class  Repository  2   {  3      Public   Static Irepository <customer> MERs  4   {  5         Get { Return Servicelocator. Current. getinstance <irepository <customer> ();}  6   }  7   8       Public   Static  Void  Commit ()  9   {  10 Servicelocator. Current. getinstance <iunitofwork> (). Commit ();  11   }  12 }

If we have a new table definition, we only need to add a new attribute. For example, add a supplier table supplier.

1Public StaticIrepository <supplier>Suppliers2 {3Get{ReturnServicelocator. Current. getinstance <irepository <supplier>();}4}
 

In this way, our businessCodeIt can be simpler,

 1       Public   Void  Insertcustomer (domainmodels. Customer customer)  2  {  3 Customer entity = Mapper. Map <domainmodels. Customer, Customer> (Customer );  4   5   Repository. Customers. insert (entity );  6   Repository. Commit ();  7   8 Customer. ID = Entity. ID;  9   }  10  11       Public   Void  Updatecustomer (domainmodels. Customer customer)  12   {  13 Customer entity = repository. MERs. Query (). Single (C => C. ID = Customer. ID );  14   15 Entity. Name = Customer. Name;  16 Entity. Address = Customer. address;  17 Entity. Phone = Customer. Phone;  18   19   Repository. MERs. Update (entity );  20   21   Repository. Commit ();  22 }
