Spring framework กับ Multi Action Controller

บทความเกี่ยวกับ : Spring framework กับ Multi Action Controller


มาดูตัวอย่างการสร้าง Multi Action กับ Spring กัน นะครับ

Controller Class

package com.en.controller;

import org.springframework.web.servlet.mvc.multiaction.MultiActionController;

import com.en.model.MasterModel;

public class MasterController extends MultiActionController{
    protected MasterModel model;
    protected String defaultScreen;
    public MasterModel getModel() {
        return model;
    }

    public void setModel(MasterModel model) {
        this.model = model;
    }

    public String getDefaultScreen() {
        return defaultScreen;
    }

    public void setDefaultScreen(String defaultScreen) {
        this.defaultScreen = defaultScreen;
    }

   
}

package com.en.controller;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.web.servlet.ModelAndView;

import com.en.dto.ExampleDto;
import com.en.model.ExampleModel;

public class ExampleController extends MasterController{
    public ModelAndView loadMethod(HttpServletRequest request, HttpServletResponse response) {
        ModelAndView mv = new ModelAndView(this.getDefaultScreen());       
        String pk=request.getParameter("code_id");
        ExampleDto dto=(ExampleDto)this.getModel().getDataObj(new Integer(pk));       
        mv.addObject("dto", dto);       
        mv.addObject("action","load");       
        return mv;
    }

    public ModelAndView insertMethod(HttpServletRequest request, HttpServletResponse response) {
        ModelAndView mv=null;
        try {
            mv = new ModelAndView(this.getDefaultScreen());       
            String pk="0";
            String tdesc=request.getParameter("tdesc");
            String edesc=request.getParameter("edesc");
            ExampleDto dto=new ExampleDto();
            dto.setCodeId(new Integer(pk));
            dto.setTdesc(tdesc);
            dto.setEdesc(edesc);
            this.getModel().insertData(dto);
            mv.addObject("dto", dto);
            mv.addObject("action","insert");
        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        return mv;
    }
   
    public ModelAndView deleteMethod(HttpServletRequest request, HttpServletResponse response) {
        ModelAndView mv = new ModelAndView(this.getDefaultScreen());       
        String pk=request.getParameter("code_id");
        ExampleDto dto=new ExampleDto();
        dto.setCodeId(new Integer(pk));
        this.getModel().deleteData(dto);       
        mv.addObject("action","delete");
        return mv;
    }
   
    public ModelAndView callWS(HttpServletRequest request, HttpServletResponse response) {
        ModelAndView mv = new ModelAndView(this.getDefaultScreen());       
        String pk=request.getParameter("code_id");
        ExampleModel model=(ExampleModel)this.model;
        ExampleDto dto=(ExampleDto)model.getDataWS(pk);       
        mv.addObject("dto",dto);       
        mv.addObject("action","ws");
        return mv;
    }
   
    public ModelAndView callSAP(HttpServletRequest request, HttpServletResponse response) {
        ModelAndView mv = new ModelAndView(this.getDefaultScreen());       
        ExampleModel model=(ExampleModel)this.model;
        model.callSAPDummy1();               
        mv.addObject("action","sap");
        return mv;
    }
 }

Controller สร้างไปเรื่อยๆ ตาม Action ที่มีเลยนะครับกำหนด Method ได้ตามใจฉันเลยทีเดียว
จากนั้นมาทำการสร้าง Spring Config ตามนี้เลย

ตามนั้นเลยครับอยากรู้อะไรเพิ่มเติมสอบถามได้
