//action的代码

package cn.itcast.actions;

import javax.annotation.Resource;
import javax.servlet.http.HttpServletRequest;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

import cn.itcast.pojos.Dep;
import cn.itcast.service.DealDaoService;

@Controller //指明这个类是一个控制器的类，处理请求的
@RequestMapping("/dep.do") //这是指明这个控制器类只能处理emp.do的请求
public class DealAction {
@Resource
private DealDaoService service;
@RequestMapping(params="p=regist")//这是指明这个方法处理p=regist的请求
public String registDep(HttpServletRequest request){

  String depname = request.getParameter("depname");
  Dep dep = new Dep();
  dep.setDepname(depname);

  service.registDep(dep);

  return "/result.jsp";//这是返回到以这个字符窜为视图的页面
}

}

//这是pojos

package cn.itcast.pojos;

public class Dep implements java.io.Serializable {
private Integer depid;
private String depname;
public Dep() {
}

public Dep(String depname) {
this.depname = depname;
}

public Integer getDepid() {
return this.depid;
}

public void setDepid(Integer depid) {
this.depid = depid;
}

public String getDepname() {
return this.depname;
}

public void setDepname(String depname) {
this.depname = depname;
}

}
