在dropwizard中

我有一个简单的dropwizard应用程序。现在当用户尝试登录时 无效的凭据，它只是不断弹出登录框（在一个 浏览器客户端）。 我希望能够抛出一个异常，返回一个允许用户使用的JSON 知道认证失败了。

我尝试了以下内容：

@Override
 public Optional<SimplePrincipal> authenticate(BasicCredentials credentials) 
throws AuthenticationException {
 DPSLookup dps = new DPSLookup(credentials.getUsername(), credentials.
getPassword(), ldap);
 if (!dps.dpsLookup()) {
                   throw new InvalidCredentialException("Access Denied");
                }
               else { 
                 SimplePrincipal user = new SimplePrincipal(credentials.
getUsername());
                 return Optional.of(user);
                }
  }

然后我有一个InvalidCredentialException类： 公共类InvalidCredentialException扩展AuthenticationException {

public InvalidCredentialException(String message) {
super(message);
}

}

然而我现在得到500响应错误，但有以下异常：

答案 0 :(得分：0)

这里最简单的方法是让InvalidCredentialException扩展NotAuthorizedException，Jersey可以理解扩展WebApplicationException的任何内容并将它们转换为适当的HTTP响应，而不是让它们在服务器上处理。由于InvalidCredentialException已经支持消息，因此最好直接抛出它。
