[Spring Framework] UserDetailsService에서 HttpServletRequest 받기

0. RequestContextListener 설정

 

web.xml에서 RequestContextListener 리스너 클래스를 등록한다.

 

<listener>
    <listener-class>
        org.springframework.web.context.request.RequestContextListener
    </listener-class>
</listener>

 

 

1. HttpServletRequest 꺼내기

 

UserDetailsService의 구현 클래스에서 RequestContextHolder에서 Request 객체를 꺼내어 사용하면 된다.

 

    @Override
    public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
        
        EmployeeVO empVO = new EmployeeVO();
        empVO.setEmpId(username);
        empVO = empMapper.login(empVO);
        
        AccessLogVO acsLogVO = new AccessLogVO();
        acsLogVO.setLogId(username);
        acsLogVO.setAcntType("EMPLOYEE");
        
        acsLogMapper.insertLog(acsLogVO);
        
        HttpServletRequest request = 
                ((ServletRequestAttributes) RequestContextHolder.getRequestAttributes())
                    .getRequest();
        
        System.out.println("---------------------------------------------");
        System.out.println("Hello there! : " + request.getRemoteAddr());
        System.out.println("---------------------------------------------");
        
        return empVO == null ? null : new EmpDetails(empVO);
    }
