權限模塊_分配權限_實現分配權限的基本功能
選哪個就能存起來那個，能回顯。有依賴關系
把一組相關功能放在一起
RoleAction.java
/** * 設置權限頁面 */ public String setPrivilegeUI() { //准備回顯的數據 Role role = roleService.getById(model.getId()); ActionContext.getContext().getValueStack().push(role);//放到棧頂,從棧頂找對象 if(role.getPrivileges() != null) { privilegeIds = new Long[role.getPrivileges().size()];//Long數組放擁有的權限Id int index = 0; for(Privilege priv : role.getPrivileges()) { privilegeIds[index++] = priv.getId();//從0開始把權限Id找出來 } } return "setPrivilegeUI"; } /** * 設置權限 */ public String setPrivilege() { //1.從數據庫中獲取原對象 Role role = roleService.getById(model.getId());//role是根據id來的 //2.設置要修改的屬性 List<Privilege> privilegeList = privilegeService.getByIds(privilegeIds); role.setPrivileges(new HashSet<Privilege>(privilegeList)); //3.更新到數據庫 roleService.update(role); return "toList"; } private Long[] privilegeIds; public void setPrivilegeIds(Long[] privilegeIds) { this.privilegeIds = privilegeIds; } public Long[] getPrivilegeIds() { return privilegeIds; }
PrivilegeService.java
public interface PrivilegeService extends DaoSupport<Privilege> { }
PrivilegeServiceImpl.java
@Service @Transactional public class PrivilegeServiceImpl extends DaoSupportImpl<Privilege> implements PrivilegeService{ }
BaseAction.java中增加
@Resource protected PrivilegeService privilegeService;
在struts.xml中崗位管理增加一個屬性
<result name="setPrivilegeUI">/WEB-INF/jsp/roleAction/setPrivilegeUI.jsp</result>
在roleAction文件夾中增加一個setPrivilegeUI.jsp頁面
setPrivilegeUI.jsp

全選
權限模塊__使用權限__實現登錄與注銷的功能
UserAction.java
/** 登錄頁面 */ public String loginUI() { return "loginUI"; } /** 登錄 */ public String login() { User user = userService.findByLoginNameAndPassword(model.getLoginName(),model.getPassword()); if(user == null) { addFieldError("login","用戶名或密碼不正確"); return "loginUI"; }else { //登錄用戶 ActionContext.getContext().getSession().put("user", user); return "toIndex"; } } /** 注銷 */ public String logout() { ActionContext.getContext().getSession().remove("user"); return "logout"; }
Struts.xml中用戶管理新增3個屬性
<result name="loginUI">/WEB-INF/jsp/userAction/loginUI.jsp</result> <result name="logout">/WEB-INF/jsp/userAction/logout.jsp</result> <result name="toIndex" type="redirectAction">/index.jsp</result
Action中
addFieldError("name", "有錯了！");
JSP中：
<s:fielderror fieldName="name"/>
<s:fielderror/>顯示全部錯誤消息
UserService.java
public interface UserService extends DaoSupport<User>{ /** * 根據用戶名與密碼查詢用戶 * @param loginName * @param password * @return */ User findByLoginNameAndPassword(String loginName, String password); }
UserServiceImpl.java
@Service @Transactional //可以不用寫了，因為父類有 public class UserServiceImpl extends DaoSupportImpl<User> implements UserService{ public User findByLoginNameAndPassword(String loginName, String password) { //使用密碼的MD5摘要進行對比 String md5Digest = DigestUtils.md5Hex(password); return (User) getSession().createQuery(// "FROM User u WHERE u.longinName=? AND u.password=?")// .setParameter(0, loginName)// .setParameter(1, md5Digest)// .uniqueResult(); } }
