配置攔截器：

package top.mschen.blog.common.config;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Component;
import org.springframework.web.servlet.HandlerInterceptor;

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

@Component
public class LogInterceptor implements HandlerInterceptor{

    private static Logger LOGGER= LoggerFactory.getLogger(LogInterceptor.class);

    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
        LOGGER.info("請求路徑：{}", request.getRequestURI());
        return true;
    }
}
 

新增攔截器：也可以直接實現WebMvcConfigurer介面

package top.mschen.blog.common.config;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.InterceptorRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;


/**
 * WebMvcConfigurationSupport
 * WebMvcConfigurerAdapter
 * WebMvcConfigurer
 */
@Configuration
public class WebMvcConfig {

    @Autowired
    private LogInterceptor logInterceptor;

    @Bean
    public WebMvcConfigurer webMvcConfigurer(){
        return new WebMvcConfigurer(){
            @Override
            public void addInterceptors(InterceptorRegistry registry) {
                registry.addInterceptor(logInterceptor).addPathPatterns("/**");
            }
        };
    }

//    /**
//     * addPathPatterns 新增攔截規則
//     * excludePathPatterns 排除攔截規則
//     *
//     * @param registry
//     */
//    @Override
//    public void addInterceptors(InterceptorRegistry registry) {
//        registry.addInterceptor(logInterceptor).addPathPatterns("/**");
//        super.addInterceptors(registry);
//    }
}
