20170318_系统管理_岗位管理_增删改查2
岗位管理_实现显示、删除、添加、修改
|-分析通用增删改查功能及命名规范
|-岗位管理----显示、删除
|-第一步：岗位管理空架action的搭建
|-第一段：action准备 和 struts.xml中配置 和 空jsp页面
|-第二段：service 准备
|-第二步：填写action中的方法内容 和 jsp页面内容 并完成测试
ps: 链接使用<s:a>自定义标签
ps：对象栈
|-岗位管理----添加、修改
步骤：action(得到参数封装成对象，并保存到数据库中)-->RoleService-->RoleServiceImpl(调用roleDao.save(role);)
=====================================================================
1 /** 列表 */ 2 public String list() throws Exception { 3 return "list"; 4 } 5 6 /** 删除 */ 7 public String delete() throws Exception { 8 return "toList"; 9 } 10 11 /** 添加页面 */ 12 public String addUI() throws Exception { 13 return "addUI"; 14 } 15 16 /** 添加 */ 17 public String add() throws Exception { 18 19 return "toList"; 20 } 21 22 /** 修改页面 */ 23 public String editUI() throws Exception { 24 25 return "editUI"; 26 } 27 28 /** 修改 */ 29 public String edit() throws Exception { 30 return "toList"; 31 }
=====================================================================
岗位管理----显示、删除
第一步：岗位管理空架搭建
第一段：action准备
RoleAction中的方法 、 struts.xml中配置<!-- 岗位管理 --> 、jsp页面（空）
注意：继承ActionSupport，添加@Controller、 @Scope("prototype")注解
第二段：service 准备
空架三层action、service、dao层搭建完成
第二步：填写action中的方法内容 和 jsp页面内容
action做一半：准备数据
页面做一半：显示数据
加在一起等于结果。
添加删除方法的内容：
ps:值栈中有：对象栈 + Map
list.jsp页面：
改进显示：
添加删除提醒：
数据库添加信息：
测试结果：
=====================================================================
岗位管理----添加、修改
添加：jsp页面-->action(得到参数封装成对象，并保存到数据库中)-->RoleService-->RoleServiceImpl(调用roleDao.save(role);)
重启服务器：
测试：
修改：
使用this.role = role.getName();和this.discription = role.getDescription();将这两个属性放到对象栈的栈顶，就可以自动回显。
测试修改：

岗位管理功能改：
栈顶放一个对象，取对象就是官方提供的一种方式即：ModelDriven

岗位管理效果修改：
显示效果：
=====================================================================
新建页面效果：
=====================================================================
修改：与addUI.jsp共用一个代码，只是表单提交数据的位置和 <s:hidden name="id"/>
