改进_使用ModelDroven方案
@Controller @Scope("prototype") public class RoleAction extends ActionSupport implements ModelDriven<Role>{//把ModelDriven放到栈顶，帮我们封装参数 //在Action里面要用到Service,用注解@Resource，另外在RoleServiceImpl类上要添加注解@Service @Resource private RoleService roleService; private Role model = new Role(); public Role getModel() { return model; } /*private Long id; //实现了ModelDriven，这些属性及setget方法就不用写了 private String name; //栈顶的Role中有了这些属性 private String description; public Long getId() { return id; } public void setId(Long id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } public String getDescription() { return description; } public void setDescription(String description) { this.description = description; }*/ /** * 列表 */ public String list() { List<Role> roleList = roleService.findAll(); ActionContext.getContext().put("roleList", roleList);//用ognl里的#号来获取map的东西 return "list"; } /** * 删除 */ public String delete() { roleService.delete(model.getId()); //取参数可以从model里获取了 return "toList"; } /** * 添加页面 */ public String addUI() { return "addUI"; } /** * 添加 */ public String add() { /*//封装到对象中 Role role = new Role(); role.setName(model.getName());//名称和说明怎么得到，跟id一样声明字段，setget方法 role.setDescription(model.getDescription()); //保存到数据库中 roleService.save(role);*/ //添加的方法可以简化成一行代码 roleService.save(model); return "toList"; } /** * 修改页面 */ public String editUI() { //准备回显的数据 Role role =roleService.getById(model.getId()); ActionContext.getContext().getValueStack().push(role);//放到栈顶,从栈顶找对象 return "editUI"; } /** * 修改 */ public String edit() { //1.从数据库中获取原对象 Role role = roleService.getById(model.getId());//role是根据id来的 //2.设置要修改的属性 role.setName(model.getName()); role.setDescription(model.getDescription()); //3.更新到数据库 roleService.update(role); return "toList"; } }
套用美工写好的页面效果
图片样式拷过来并指定正确的路径
从静态页面中拷贝这两个文件夹
分别在list.jsp、addUI.jsp、editUI.jsp中替换美工做好的页面代码
修改路径
添加循环<s:iterator>及修改里面的name，description和删除修改添加的超链接
修改完的list.jsp

添加功能与修改功能使用同一个页面
添加的时候不用隐藏id，提交的地址不一样，其他差不多一样
addUI.jsp和editUI.jsp保留一个并改名为savaUI.jsp
同时在struts.xml文件中要修改
<result name="saveUI">/WEB-INF/jsp/roleAction/saveUI.jsp</result>
下一步要修改RoleAction.java中的return
return "saveUI";
saveUI.jsp
