Hibernate+SpringMVC整合:实战三,…

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);

request.setAttribute("department", department);

return "/department/updateDepartment";

}

@RequestMapping(value="updateDepartment")

public String updateDepartment(Department department) {

iDepartmentService.updateEntity(department);

return "redirect:/department/showAllDepartments";

}

public String deleteDepartment(Long 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">

部门名称:<input type="text" name="dname"><br/>

部门描述:<textarea rows="5" cols="20" name="description"></textarea><br/>

<input type="reset" value="重置">

<input type="submit" value="提交">

</form>

updateDepartment.jsp:

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

<input type="hidden" name="did" value="${department.did}">

部门名称:<input type="text" name="dname" value="${department.dname }"><br/>

部门描述:<textarea rows="5" cols="20" name="description">${department.description }</textarea><br/>

<input type="reset" value="重置">

<input type="submit" value="提交">

</form>
