本文介绍如何在 Spring MVC 中实现自定义拦截器及参数解析器，包括配置 WebAdapter 类来添加请求拦截器和参数解析器，实现权限验证等功能。

1.

@Configuration
public class ApplicationWebAdapter extends WebMvcConfigurerAdapter {
   @Override
   public void addArgumentResolvers(List<HandlerMethodArgumentResolver> argumentResolvers) {
      super.addArgumentResolvers(argumentResolvers);
      argumentResolvers.add(new LaborHeaderResolver());
   }
   @Override
   public void addInterceptors(InterceptorRegistry registry) {
      registry.addInterceptor(new LogInterceptor())
         .addPathPatterns("/**");
      super.addInterceptors(registry);
   }
}

2.

public class AuthenticationInterceptor implements HandlerInterceptor {

	@Autowired
	private UserService userService;

	@Override
	public boolean preHandle(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse,
		Object handler) throws Exception {
		// 如果不是映射到方法直接通过
		if (!(handler instanceof HandlerMethod)) {
			return true;
		}
		HandlerMethod handlerMethod = (HandlerMethod)handler;
		Method method = handlerMethod.getMethod();
		LoginRequired methodAnnotation = method.getAnnotation(LoginRequired.class);
		if (methodAnnotation != null) {
	
		}
		return true;
	}
	@Override
	public void postHandle(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Object o,
		ModelAndView modelAndView) throws Exception {

	}

	@Override
	public void afterCompletion(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse,
		Object o, Exception e) throws Exception {


	}
