[Spring Boot] Interceptor 설정하기

이번에는 Interceptor 에 대해서 포스팅하고자 합니다. 

Interceptor 에 대한 기본이해는 이미 하셨으리라 생각하고 설정하는 부분만 나갑니다.

src/main/java/kr.mythsoft.stats/common/Interceptor/StatsInterceptor.java

package kr.mythsoft.stats.common.Interceptor;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Component;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.handler.HandlerInterceptorAdapter;

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

/**

@Component
public class StatsInterceptor extends HandlerInterceptorAdapter {
    private static final Logger logger = LoggerFactory.getLogger(StatsInterceptor.class);

    @Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
        logger.info("Interceptor > preHandle");
        return true;
    }

    @Override
    public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler, ModelAndView modelAndView) throws Exception {
        logger.info("Interceptor > postHandle");
    }

    @Override
    public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object object, Exception arg3) throws Exception {
        logger.info("Interceptor > afterCompletion" );
    }
}

src/main/java/kr.mythsoft.stats/config/StatsConfig.java

package kr.mythsoft.stats.config;

import kr.mythsoft.stats.common.Interceptor.StatsInterceptor;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.InterceptorRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;

/**

 */
@Configuration
public class StatsConfig extends WebMvcConfigurerAdapter {
    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        registry.addInterceptor(new StatsInterceptor());
    }
}
