P4jmvc beta version

(Declaration: currently, the p4jmvc internal beta version only supports spring MVC and is only for your technical reference .)

Attachment Source: http://download.csdn.net/detail/partner4java/5220557

Purpose: simplify the controller and perform common curd operations. The controller does not need to write a line of code, but only needs to inherit the code.

Note: p4jmvc mainly uses p4jorm.

For example, we only need to input a fixed parameter ID to modify and delete the city information controller)

Inherited from basemanageview, you only need to complete two additional points:

1. Input two generic types: entity and formbean;

2. input the parameter constructorBasemanageview p4jdao.

@Controller@RequestMapping("/manage/city/*")public class CityManageView extends BaseManageView<City, CityForm>{@SuppressWarnings("unused")private CityService cityService;@Autowiredpublic CityManageView(CityService cityService) {super(cityService);this.cityService = cityService;}}

The core functions are provided by class basemanageview (For details, refer to the source code of the attachment ):
