protected boolean executeLogin(jakarta.servlet.ServletRequest request,
 jakarta.servlet.ServletResponse response)
                        throws Exception

Throws:

Exception

createToken

protected abstract org.apache.shiro.authc.AuthenticationToken createToken(jakarta.servlet.ServletRequest request,
 jakarta.servlet.ServletResponse response)
                                                                   throws Exception

Throws:

Exception

createToken

 String password,
 jakarta.servlet.ServletRequest request,
 jakarta.servlet.ServletResponse response)

createToken

protected org.apache.shiro.authc.AuthenticationToken createToken(String username,
 String password,
 boolean rememberMe,
 String host)

onLoginSuccess

protected boolean onLoginSuccess(org.apache.shiro.authc.AuthenticationToken token,
 org.apache.shiro.subject.Subject subject,
 jakarta.servlet.ServletRequest request,
 jakarta.servlet.ServletResponse response)
                          throws Exception

Throws:

Exception

onLoginFailure

protected boolean onLoginFailure(org.apache.shiro.authc.AuthenticationToken token,
 org.apache.shiro.authc.AuthenticationException e,
 jakarta.servlet.ServletRequest request,
 jakarta.servlet.ServletResponse response)

getHost

protected String getHost(jakarta.servlet.ServletRequest request)

Returns the host name or IP associated with the current subject. This method is primarily provided for use during construction of an AuthenticationToken.

The default implementation merely returns ServletRequest.getRemoteHost().

Parameters:

request - the incoming ServletRequest

Returns:

the InetAddress to associate with the login attempt.

isRememberMe

protected boolean isRememberMe(jakarta.servlet.ServletRequest request)

Returns true if "rememberMe" should be enabled for the login attempt associated with the current request, false otherwise.

This implementation always returns false and is provided as a template hook to subclasses that support rememberMe logins and wish to determine rememberMe in a custom mannner based on the current request.

Parameters:

request - the incoming ServletRequest

Returns:

true if "rememberMe" should be enabled for the login attempt associated with the current request, false otherwise.
