- protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authcToken) throws AuthenticationException {
- UsernamePasswordToken token = (UsernamePasswordToken) authcToken;
- User user = accountManager.findUserByUserName(token.getUsername());
- if (user != null) {
- return new SimpleAuthenticationInfo(user.getUserName(), user.getPassword(), getName());
- } else {
- return null;
- }
- }
二、授权实现
而授权实现则与认证实现非常相似,在我们自定义的Realm中,重载doGetAuthorizationInfo()方法,重写获取用户权限的方法即可。
- protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
- String userName = (String) principals.fromRealm(getName()).iterator().next();
- User user = accountManager.findUserByUserName(userName);
- if (user != null) {
- SimpleAuthorizationInfo info = new SimpleAuthorizationInfo();
- for (Group group : user.getGroupList()) {
- info.addStringPermissions(group.getPermissionList());
- }
- return info;
- } else {
- return null;
- }
- }
