@Component
public class AuthorizeInterceptor extends HandlerInterceptorAdapter {

    private Logger log = LoggerFactory.getLogger(AuthorizeInterceptor.class);

    @Autowired
    private Environment env;

    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
        log.info("env:",env);
        return true;
    }
}

env是null，某些使用@Value()的配置也无法获取值，总是null
我们添加这个拦截器registry.addInterceptor(new Interceptor()).addPathPatterns("/**");是new！
获得价值的一种方法是BeanFactory.getBean("beanname")。
但是我怎样才能让Spring Manager这个拦截器，所以我可以使用@Autowired

最佳答案

应该是log.info("env: {}", env);

我相信您忘记了在记录器调用中放置占位符{}。
