package com.lrq.sh.web.controller;

import java.util.Collection;

import javax.servlet.http.HttpServletRequest;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

import com.itheima.sh.domain.Department;
import com.itheima.sh.service.IDepartmentService;

@Controller
@RequestMapping(value = "/department")
public class DepartmentController {
       @Autowired
  IDepartmentService iDepartmentService;

  @RequestMapping(value = "addDepartment")
    public String addDepartment(Department department) {
                iDepartmentService.saveEntity(department);
          return "redirect:/department/showAllDepartments";
   }
   @RequestMapping(value = "addUI")
    public String addUI(){
              return "/department/addDepartment";

       @RequestMapping(value = "showAllDepartments")
       public String showAllDepartments(HttpServletRequest request) {
              Collection<Department> departments = iDepartmentService
                               .getAllEntities();
          request.setAttribute("departments", departments);
           return "/department/showAllDepartments";
    }
   @RequestMapping(value="updateUI")
   public String updateUI(HttpServletRequest request,Long did){
                Department department = iDepartmentService.getEntity(Department.class, did);

           iDepartmentService.deleteEntity(did);
               return "redirect:/department/showAllDepartments";

}

对应的jsp页面showAllDepartments.jsp


<c:forEach items="${departments }" var="department">
                                   <tr>
                                          <td>${department.dname }</td>
                                           <td>${department.description }</td>
                                     <td>
                                                  <a href="http://rongqiang1992.blog.163.com/blog/${pageContext.request.contextPath }/department/updateUI?did=${department.did }">
                                                      修改
                                              </a>
                                                  <a href="http://rongqiang1992.blog.163.com/blog/${pageContext.request.contextPath }/department/deleteDepartment?did=${department.did }">
                                                       除
                                              </a>
                                          </td>
                                 </tr>
                         </c:forEach>
                          <tr>
                                  <td>
                                          <a href="http://rongqiang1992.blog.163.com/blog/${pageContext.request.contextPath }/department/addUI">添 部门</a>
                                  </td>
                         </tr>

注意:我的jsp页面的路径:是WEB-INF/jsp/department/xxx;
因此在控制器返回的路由串中需要加上对应的路径,department;(重定向除外);
addDepartment.jsp

<form action="${pageContext.request.contextPath }/department/addDepartment" method="post">
