# 1. 編寫 一個類 并且實現AccessDeniedHandler 的 handle 方法
```
import org.springframework.security.access.AccessDeniedException;
import org.springframework.security.web.access.AccessDeniedHandler;
import org.springframework.stereotype.Component;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
//
@Component
public class WebAccessDeniedHandler implements AccessDeniedHandler {
@Override
public void handle(HttpServletRequest request, HttpServletResponse response, AccessDeniedException accessDeniedException) throws IOException, ServletException {
System.out.println("授權失敗");
}
}
```
# 2. 在配置文件中添加配置
~~~
@Autowired
private WebAccessDeniedHandler accessDeniedHandler;
@Override
protected void configure(HttpSecurity http) throws Exception {
http.exceptionHandling()
.accessDeniedHandler(accessDeniedHandler); // 失敗處理的邏輯
）
~~~
