SpringBoot自定义拦截器

### 1、创建拦截类 ###

@Configuration
    public class InterceptorAdapterConfig implements WebMvcConfigurer {
        
    
        @Override
        public void addInterceptors(InterceptorRegistry interceptorRegistry) {
        
            InterceptorRegistration registry = interceptorRegistry.addInterceptor(new InterceptorConfigurer());
    
            registry.addPathPatterns("/**");
        }
    
    }

### 2、创建具体拦截配置 ###

import javax.servlet.http.HttpServletRequest;
    import javax.servlet.http.HttpServletResponse;
    import java.util.ArrayList;
    import java.util.Map;
    
    /**
     * 系统中的拦截器配置
     */
    
    public class InterceptorConfigurer implements HandlerInterceptor {
        
        private Logger logger = LoggerFactory.getLogger(InterceptorConfigurer.class);
    
        @Override
        public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object o) throws Exception {
        
            try {
        
                // 这里面可以写自己想搞的业务
    	   String token="";
    	   String userId="";
       
                // 不做拦截的地址
                if (!checkRequestURI(request)) {
        
                  
                }
                return true;
            } catch (Exception e) {
        
                throw new Exception(e.getMessage(), e);
            }
        }
    
        public boolean checkRequestURI(HttpServletRequest request) {
        
            if (request.getRequestURI().equals("*****")) {
        
                return true;
            }
            return false;
        }
    
        @Override
        public void postHandle(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Object o,
                               ModelAndView modelAndView) {
        
            // Do nothing because of X and Y.
        }
    
        @Override
        public void afterCompletion(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse,
                                    Object o, Exception e) {
        
            // Do nothing because of X and Y.
        }
    
    }
