我正在调用适配器并使用自定义登录模块保护该适配器，但我未定义任何自定义身份验证器。
然后我创建了一个我调用此适配器的Web服务，现在当它调用它时，它会显示调用进入自定义登录模块的凭据，然后出现以下异常。

我的自定义登录模块：
public class MyCustomLoginModule implements WorkLightLoginModule {
private String USERNAME ,PASSWORD;
public void init(Map<String, String> options) throws MissingConfigurationOptionException {
}
public MyCustomLoginModule() {
ResourceBundle rb = ResourceBundle.getBundle("cardappsettings", Locale.ENGLISH);
USERNAME = rb.getString("DispatcherPushUserID") ;
PASSWORD = rb.getString("DispatcherPushUserPassword") ;
}
public boolean login(Map<String, Object> authenticationData) {
System.out.println("Inside Push Adapter ");
System.out.println("login was called: " + ((String)authenticationData.get("user.name")) +"/"+ ((String)authenticationData.get("user.password")));
System.out.println("user name:"+ ((String)authenticationData.get("user.name")).equals(USERNAME) );
System.out.println("user password:"+ ((String)authenticationData.get("user.password")).equals(PASSWORD) );
if (((String)authenticationData.get("user.name")).equals(USERNAME) && ((String)authenticationData.get("user.password")).equals(PASSWORD))
{ System.out.println("MyCustomLoginModule - User authenticated Successfully");
return true;
}
else
{ System.out.println("MyCustomLoginModule - throwing exception...");
throw new RuntimeException("Invalid credentials");}
}
public UserIdentity createIdenity(String loginModule) {
HashMap<String, Object> customAttributes = new HashMap<String, Object>();
customAttributes.put("AuthenticationDate", new Date());
UserIdentity identity = new UserIdentity(loginModule, USERNAME, null, null, customAttributes, PASSWORD);
return identity;
}
public void logout() {
USERNAME = null;
PASSWORD = null;
}
public void abort() {
USERNAME = null;
PASSWORD = null;
}
@Override
public MyCustomLoginModule clone() throws CloneNotSupportedException {
return (MyCustomLoginModule) super.clone();
}
}
我的 authenticationConfig.xml
<loginModule name="PushAppLoginModule">
<className>com.rc.MyCustomLoginModule</className>
</loginModule>
请建议，我是否需要声明自定义身份验证器？或者其他任何东西都缺失了。
非常感谢

首先，您必须一起使用authenticator和loginmodule。登录模块知道如何验证凭据，但它没有关于如何收集凭据的线索。根据您的登录模块代码看起来您的凭据是用户名和密码。在这种情况下，您可以使用开箱即用的FormBasedAuthenticator（参见WL入门）。如果您需要一些自定义逻辑，则需要实现自定义验证器以及登录模块。
