认证
jsp页面进行登录
<form action="login" method="post">
<table>
<tr>
<td>用户名：</td>
<td><input type="text" name="name"/></td>
</tr>
<tr>
<td>密码：</td>
<td><input type="password" name="password"/></td>
</tr>
<tr>
<td>登录</td>
<td><input type="submit"/></td>
</tr>
</table>
</form>
验证用户
@RequestMapping(value = "/login",method = RequestMethod.POST)
public String logins(User user) {
Subject currentUser = SecurityUtils.getSubject();
if (!currentUser.isAuthenticated()) {
UsernamePasswordToken token = new UsernamePasswordToken(user.getName(),user.getPassword());
//记住密码
token.setRememberMe(true);
try {
//这里会调用认证方法
currentUser.login(token);
System.out.println("登录成功!");
return "welcome";
} catch (UnknownAccountException uae) {
System.out.println("用户名错误"+token.getPrincipal());
} catch (IncorrectCredentialsException ice) {
System.out.println("密码错误"+token.getPrincipal());
} catch (LockedAccountException lae) {
System.err.println("账号已经锁定"+token.getPrincipal());
}
catch (AuthenticationException ae) {
System.out.println("发生其他错误！");
throw ae;
}
}
return "login";
}
进行认证
public class ShiroRealm extends AuthenticatingRealm{
//认证方法
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
//①、把AuthenticationToken转换为UsernamePasswordToken。
UsernamePasswordToken upToken = (UsernamePasswordToken) token;
//②、从UsernamePasswordToken中获取username
String username = upToken.getUsername();
//③、调用数据库的方法，从数据库中查询username对应的记录。
UserService userService = new UserService();
User user = userService.login(username);
//④、若用户不存在，则可以跑出UnknownAccountException异常。
if(user == null) {
throw new UnknownAccountException("用户不存在");
}
//⑤、根据用户信息的情况，决定是否需要抛出其它AuthenticationException异常。
if(user.isLock()) {
throw new LockedAccountException("用户被锁定");
}
//盐值
ByteSource salt = ByteSource.Util.bytes("www.znsd.com");
//⑥、根据用户的情况，来构建AuthenticationInfo对象并返回。
AuthenticationInfo info = new SimpleAuthenticationInfo(user,user.getPassword(),salt,this.getName());
return info;
}
这里我只是模拟一下，真正的还是要查询数据库的
@Service
public class UserService {
public User login(String name) {
if("admin".equals(name)) {
//ture就是锁定的意思
User user=new User("admin","5489abfd2e375f20485584c704a1a9da",false);
return user;
}
if("zhangsan".equals(name)) {
User user=new User("张三","b961a66f118748a2b9d73d72c65870b7",false);
return user;
}
return null;
}
}
授权(在认证的基础上进行添加)
在这里的授权的意思是一些页面需要授权给用户才能访问一些页面。
授权要实现AuthorizingRealm，刚好是AuthenticatingRealm认证的子类，所以有两个方法。
public class ShiroRealm extends AuthorizingRealm{
//认证方法
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
//①、把AuthenticationToken转换为UsernamePasswordToken。
UsernamePasswordToken upToken = (UsernamePasswordToken) token;
//②、从UsernamePasswordToken中获取username
String username = upToken.getUsername();
//③、调用数据库的方法，从数据库中查询username对应的记录。
UserService userService = new UserService();
User user = userService.login(username);
//④、若用户不存在，则可以跑出UnknownAccountException异常。
if(user == null) {
throw new UnknownAccountException("用户不存在");
}
//⑤、根据用户信息的情况，决定是否需要抛出其它AuthenticationException异常。
if(user.isLock()) {
throw new LockedAccountException("用户被锁定");
}
//盐值
ByteSource salt = ByteSource.Util.bytes("www.znsd.com");
//⑥、根据用户的情况，来构建AuthenticationInfo对象并返回。
AuthenticationInfo info = new SimpleAuthenticationInfo(user,user.getPassword(),salt,this.getName());
return info;
}
//授权方法
@Override
protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
System.out.println("执行授权的操作！");
// 授权方法的步骤：
// 1、从PrincipalCollection中来获取登录用户的信息。
User user = (User)principals.getPrimaryPrincipal();
// 2、利用登录用户的信息来验证当前用户的角色或者权限。
Set<String> roles = new HashSet<>();
SimpleAuthorizationInfo info = new SimpleAuthorizationInfo(roles);
roles.add("user");
if ("admin".equals(user.getName())) {
roles.add("admin");
roles.add("user:query");
info.setStringPermissions(roles);
}
return info;
}
}
添加了两种验证策略(其实上面已经配置了的，只是单独拿出来,比较好看点)
