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
