要自定義Spring Security失敗登錄的處理邏輯,可以通過實現AuthenticationFailureHandler接口來實現。具體步驟如下:
import org.springframework.security.core.AuthenticationException;
import org.springframework.security.web.authentication.AuthenticationFailureHandler;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
public class CustomAuthenticationFailureHandler implements AuthenticationFailureHandler {
@Override
public void onAuthenticationFailure(HttpServletRequest request, HttpServletResponse response, AuthenticationException exception) throws IOException, ServletException {
// 處理登錄失敗的邏輯
System.out.println("登錄失敗");
}
}
@Configuration
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
@Autowired
private CustomAuthenticationFailureHandler customAuthenticationFailureHandler;
@Override
protected void configure(HttpSecurity http) throws Exception {
http
.formLogin()
.loginPage("/login")
.failureHandler(customAuthenticationFailureHandler);
}
}
通過以上步驟,就可以實現自定義Spring Security失敗登錄的處理邏輯。在登錄失敗時,會調用CustomAuthenticationFailureHandler中的onAuthenticationFailure方法來處理登錄失敗的邏輯。
