@wendal 这样 public Object doLogin(@Attr("loginToken") AuthenticationToken token, HttpServletRequest req, HttpSession session) {} 的方法中，HttpServletRequest req 算是请求吗？

@wendal 从客户端向服务端发送请求产生req对象，我是从定时任务调用另一个方法怎么产生请求呢？（基础不好。。。。）

@wendal 嗯 我试试

@wendal 我是这样写的 还是为null

@IocBean(args = {"refer:dao"})
public class ZuzhijigouService extends Service<sw_zuzhijigou> {

	private static final Log log = Logs.get();
	
    public ZuzhijigouService(Dao dao) {
        super(dao);
    }
    
    XmlanlayService xmlanlayService;
 	
    @Inject
    SysLogService sysLogService;
 	//操作数据库将数据存入数据库
 	public int save(File file) throws DocumentException, ParseException{
 		
 		int r = 1;
 		List<Map<String,String>> list = xmlanlayService.xmlChangeString(file);
 		if(list.size()!=0) {
 			//逻辑处理
 	        			
 	        			
 	    		sysLogService.async(Sys_log.c("info", "执行存入日志", "执行成功", null));
 	    	}else {
 	    		log.info("无返回数据");
 	    	}
 		return r;
    		
    }

sysLogService（不是我写的类）

        LinkedBlockingQueue<Sys_log> queue = this.queue;
        if (queue != null)
            try {

Sys_log （也不是我写的类）

 public static Sys_log c(String type, String tag, String msg, String source) {
        Sys_log sysLog = new Sys_log();
        if (type == null || tag == null || msg == null) {
            throw new RuntimeException("type/tag/msg can't null");
        }
        if (source == null) {
            StackTraceElement[] tmp = Thread.currentThread().getStackTrace();
            if (tmp.length > 2) {
                source = tmp[2].getClassName() + "#" + tmp[2].getMethodName();
            } else {
                source = "main";
            }

        }
        sysLog.type = type;
        sysLog.tag = tag;
        sysLog.src = source;
        sysLog.msg = msg;
        sysLog.ip = StringUtil.getRemoteAddr();
        Object u = SecurityUtils.getSubject().getPrincipal();
        String uid = "";
        String nickname = "";
        if (u != null) {
            if (u instanceof Sys_user) {
                nickname = ((Sys_user) u).getNickname();
                uid = ((Sys_user) u).getId();
            } else if (u instanceof String) {
                nickname = ((String) u);
            }
        }
        sysLog.setOpBy(uid);
        sysLog.setOpAt((int) (System.currentTimeMillis() / 1000));
        sysLog.nickname = nickname;
        return sysLog;
    }

@wendal 是取ip 调用的类（下面的方法）调取 Mvcs.getReq(); 为空 想弄明白什么原理。。。

public static String getRemoteAddr() {
        HttpServletRequest request = Mvcs.getReq();
        String remoteAddr = request.getHeader("X-Real-IP");
        if (Strings.isNotBlank(remoteAddr)) {
            remoteAddr = request.getHeader("X-Forwarded-For");
        } else if (Strings.isNotBlank(remoteAddr)) {
            remoteAddr = request.getHeader("Proxy-Client-IP");
        } else if (Strings.isNotBlank(remoteAddr)) {
            remoteAddr = request.getHeader("WL-Proxy-Client-IP");
        }
        String ip = remoteAddr != null ? remoteAddr : Strings.sNull(request.getRemoteAddr());
        if (isIPv4Address(ip) || isIPv6Address(ip)) {
            return ip;
        }
        return "";
    }

@wendal 我明白了 多谢！
