如何在java spring中为请求添加用户名和密码

import org.springframework.web.servlet.HandlerInterceptor;
import org.springframework.web.servlet.ModelAndView;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class AuthInterceptor implements HandlerInterceptor {

    @Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
        // 在请求头中添加用户名和密码
        request.addHeader("username", "your_username");
        request.addHeader("password", "your_password");
        return true;
    }

    @Override
    public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler, ModelAndView modelAndView) throws Exception {
        // 在请求处理完成后的操作
    }

    @Override
    public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex) throws Exception {
        // 在请求完成后的操作
    }
}

@Configuration
public class AppConfig extends WebMvcConfigurerAdapter {

    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        registry.addInterceptor(new AuthInterceptor()).addPathPatterns("/**");
    }
}

@Configuration
public class AppConfig {

    @Bean
    public AuthInterceptor authInterceptor() {
        return new AuthInterceptor();
    }

    @Configuration
    public class WebMvcConfig extends WebMvcConfigurerAdapter {

        @Autowired
        private AuthInterceptor authInterceptor;

        @Override
        public void addInterceptors(InterceptorRegistry registry) {
            registry.addInterceptor(authInterceptor).addPathPatterns("/**");
        }
    }
}
