</beans>4. 控制器實現
(1)命令控制器
package com.zf.ssh.test.controller;
import java.util.HashMap;
import java.util.Map;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.BaseCommandController;
import com.zf.ssh.test.Command;
public class CommandController extends BaseCommandController
{
private String viewPage;
@Override
protected ModelAndView handleRequestInternal(HttpServletRequest arg0, HttpServletResponse arg1) throws Exception
{
// create bean.
Object commandObject = getCommand(arg0);
bindAndValidate(arg0, commandObject);
Command command = (Command) commandObject;
Map<String, String> modeMap = new HashMap<String, String>();
modeMap.put("command", command.getCommand());
return new ModelAndView(getViewPage(), modeMap);
}
public String getViewPage()
{
return viewPage;
}
public void setViewPage(String viewPage)
{
this.viewPage = viewPage;
}
}
(2)表單控制器
package com.zf.ssh.test.controller;
import java.util.HashMap;
import java.util.Map;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.SimpleFormController;
import com.zf.ssh.test.Command;
public class FormController extends SimpleFormController
{
private String viewPage;
public String getViewPage()
{
return viewPage;
}
public void setViewPage(String viewPage)
{
this.viewPage = viewPage;
}
public ModelAndView onSubmit(Object command)
{
Command content = (Command) command;
Map<String, String> modelMap = new HashMap<String, String>();
modelMap.put("form", content.getCommand());
return new ModelAndView(getViewPage(), modelMap);
}
}
(3)多動作控制器
package com.zf.ssh.test.controller;
import java.util.HashMap;
import java.util.Map;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.web.servlet.ModelAndView;
public class MultiActionController extends org.springframework.web.servlet.mvc.multiaction.MultiActionController
{
private String viewPage;
public String getViewPage()
{
return viewPage;
}
public void setViewPage(String viewPage)
{
this.viewPage = viewPage;
}
public ModelAndView insert(HttpServletRequest req, HttpServletResponse res)
{
String content = (String) req.getParameter("multiAction");
Map<String, String> modelMap = new HashMap<String, String>();
modelMap.put("multiAction", "INSERT: " + content);
return new ModelAndView(getViewPage(), modelMap);
}
public ModelAndView update(HttpServletRequest req, HttpServletResponse res)
{
String content = (String) req.getParameter("multiAction");
Map<String, String> modelMap = new HashMap<String, String>();
modelMap.put("multiAction", "UPDATE: " + content);
return new ModelAndView(getViewPage(), modelMap);
}
public ModelAndView delete(HttpServletRequest req, HttpServletResponse res)
{
String content = (String) req.getParameter("multiAction");
Map<String, String> modelMap = new HashMap<String, String>();
modelMap.put("multiAction", "DELETE: " + content);
return new ModelAndView(getViewPage(), modelMap);
}
}
5.數據類
package com.zf.ssh.test;
public class Command
{
private String command;
public String getCommand()
{
return command;
}
public void setCommand(String command)
{
this.command = command;
}
}
