权限模块_分配权限_实现分配权限的基本功能

选哪个就能存起来那个，能回显。有依赖关系

把一组相关功能放在一起

RoleAction.java

    /**
     * 设置权限页面
     */
    public String setPrivilegeUI() {
        
        //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
        
        if(role.getPrivileges() != null) {
            privilegeIds = new Long[role.getPrivileges().size()];//Long数组放拥有的权限Id
            int index = 0;
            for(Privilege priv : role.getPrivileges()) {
                privilegeIds[index++] = priv.getId();//从0开始把权限Id找出来
                
            }
        }
        return "setPrivilegeUI";
    }
    /**
     * 设置权限
     */
    public String setPrivilege() {
        //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
        List<Privilege> privilegeList = privilegeService.getByIds(privilegeIds);
        role.setPrivileges(new HashSet<Privilege>(privilegeList));
        
        //3.更新到数据库
        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中岗位管理增加一个属性

<result name="setPrivilegeUI">/WEB-INF/jsp/roleAction/setPrivilegeUI.jsp</result>

在roleAction文件夹中增加一个setPrivilegeUI.jsp页面

setPrivilegeUI.jsp

全选

权限模块使用权限实现登录与注销的功能

UserAction.java

/** 登录页面 */
    public String loginUI() {
        
        return "loginUI";
    }
    /** 登录 */
    public String login() {
        User user = userService.findByLoginNameAndPassword(model.getLoginName(),model.getPassword());
        if(user == null) {
            addFieldError("login","用户名或密码不正确");
            return "loginUI";
        }else {
            //登录用户
            ActionContext.getContext().getSession().put("user", user);
            return "toIndex";
        }
        
    }
    /** 注销 */
    public String logout() {
        ActionContext.getContext().getSession().remove("user");
        return "logout";
    }

Struts.xml中用户管理新增3个属性

　　 <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", "有错了！");

JSP中：

　　<s:fielderror fieldName="name"/>

　　<s:fielderror/>显示全部错误消息

UserService.java

public interface UserService extends DaoSupport<User>{
    /**
     * 根据用户名与密码查询用户
     * @param loginName
     * @param password
     * @return
     */
    User findByLoginNameAndPassword(String loginName, String password);

}

UserServiceImpl.java

@Service
@Transactional    //可以不用写了，因为父类有
public class UserServiceImpl extends DaoSupportImpl<User> implements UserService{

    public User findByLoginNameAndPassword(String loginName, String password) {
        
        //使用密码的MD5摘要进行对比
        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();
    }
}
