spring boot Interceptor 설정

spring boot Interceptor 설정 하는 방법 입니다.

생각 보다 간단 하네요.



우선 WebMvcConfig.java



package com.kr.spot.system;
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.DefaultServletHandlerConfigurer;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.config.annotation.InterceptorRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
import org.springframework.web.servlet.view.InternalResourceViewResolver;

/** * Created by ian on 2017. 7. 12.. */
@Configuration@EnableWebMvc
public class WebMvcConfig extends WebMvcConfigurerAdapter {
   
   @Override   
   public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) {
      configurer.enable();   }

   @Bean   
   public InternalResourceViewResolver viewResolver() {
      InternalResourceViewResolver resolver = new InternalResourceViewResolver();      
      resolver.setPrefix("views/");      
      resolver.setSuffix(".jsp");      
      return resolver;   
   }

   /* 로그인 인증 Interceptor 설정 */   
   @Autowired   
   private com.kr.spot.system.LoginInterceptor loginInterceptor;   
   /* 캐시 Interceptor 설정 */   
   @Autowired    
   private com.kr.spot.system.CachingInterceptor cachingInterceptor;   
   /* 기본 Interceptor 설정 */   
   @Autowired   
   private com.kr.spot.system.BaseInterceptor baseInterceptor;
   
   @Override   
   public void addInterceptors(InterceptorRegistry registry) {
      registry.addInterceptor(loginInterceptor)
            .addPathPatterns("/**")
            .excludePathPatterns("/CO0301/**");

      registry.addInterceptor(cachingInterceptor)
            .addPathPatterns("/**")
            .excludePathPatterns("/CO0301/**");

      registry.addInterceptor(baseInterceptor)
            .addPathPatterns("/**");   
   }

}




addPathPatterns 는 Interceptor 가 실행 되어야할 페이지 규칙

excludePathPatterns 는 Interceptor 가 실행 제외되어야할 페이지 규칙 입니다.



다음은 LoginInterceptor.java 입니다.



package com.kr.spot.system;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Component;
import org.springframework.web.servlet.HandlerInterceptor;
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 LoginInterceptor implements HandlerInterceptor {
   
   private static final Logger logger = LoggerFactory.getLogger(LoginInterceptor.class);      

   @Override   
   public boolean preHandle( HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
      //로그인 정보 확인 및 처리            
      //1. 세션 정보 확인       
      if(request.getSession().getAttribute("sEmpNo") == null){
         // 로그인 페이지 이동          
         logger.info( "go login page");         
         response.sendRedirect("/CO0301");      
      }
      
      return true;   
   }

   @Override   public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler,                          
                                      ModelAndView modelAndView) throws Exception {
      // TODO Auto-generated method stub   
   }

   @Override   public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex)
         throws Exception {
      // TODO Auto-generated method stub   }

   }


이렇게 하시면 됩니다.

크게 어려울건 없네요.



spring boot 설정 하면서 이게 제일 쉬운거 같네여 ㅜㅜ
