springsecurity4添加验证码的示例代码-创新互联
spring security是一个很大的模块,本文中只涉及到了自定义参数的认证。spring security默认的验证参数只有username和password,一般来说都是不够用的。由于时间过太久,有些忘,可能有少许遗漏。好了,不废话。
spring以及spring security配置采用javaConfig,版本依次为4.2.5,4.0.4
总体思路:自定义EntryPoint,添加自定义参数扩展AuthenticationToken以及AuthenticationProvider进行验证。
首先定义EntryPoint:
import org.springframework.security.core.AuthenticationException; import org.springframework.security.web.authentication.LoginUrlAuthenticationEntryPoint; import javax.servlet.ServletException; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import java.io.IOException; public class MyAuthenticationEntryPoint extends LoginUrlAuthenticationEntryPoint { public MyAuthenticationEntryPoint(String loginFormUrl) { super(loginFormUrl); } @Override public void commence(HttpServletRequest request, HttpServletResponse response, AuthenticationException authException) throws IOException, ServletException { super.commence(request, response, authException); } }
