目前遇到的用法基本上是这样的，@SLog(tag = "Add", msg = "Add:sOrder")
如果想要使用它纪录异常，目前wk(并非最新的slog)该怎么改呢？

@At("/test")
	@SLog(tag = "test", msg = "${obj.msg}")
	public Object test(HttpServletRequest req) {
		try {
			throw new RuntimeException("456");
		} catch (Exception e) {
			return Result.error("test-error");
		}
	}

result构造

public Result(int code, String msg, Object data) {
        this.code = code;
        this.msg = Mvcs.getMessage(Mvcs.getActionContext().getRequest(), msg);
        this.data = data;
    }

本来想用 msg = "${obj.xxx}"
看了帖子发现obj好像是被注解的方法所在的类。
目前SysLogAopInterceptor的方法

  public SysLogAopInterceptor(SysLogService sysLogService, SLog slog, Method method) {
        this.msg = new CharSegment(slog.msg());
        if (msg.hasKey()) {
            els = new HashMap<String, El>();
            for (String key : msg.keys()) {
                els.put(key, new El(key));
            }
        }
        this.sysLogService = sysLogService;
        this.source = method.getDeclaringClass().getName() + "#" + method.getName();
        this.tag = slog.tag();
        SLog _s = method.getDeclaringClass().getAnnotation(SLog.class);
        if (_s != null) {
            this.tag = _s.tag() + "," + this.tag;
        }
        this.async = slog.async();
        this.before = slog.before();
        this.after = slog.after();
        this.error = slog.error();
    }

    public void filter(InterceptorChain chain) throws Throwable {
        if (before)
            doLog("aop.before", chain, null);
        try {
            chain.doChain();
            if (after)
                doLog("aop.after", chain, null);
        } catch (Throwable e) {
            if (error)
                doLog("aop.after", chain, e);
            throw e;
        }
    }

    protected void doLog(String t, InterceptorChain chain, Throwable e) {
        String _msg = null;
        if (msg.hasKey()) {
            Context ctx = Lang.context();
            ctx.set("args", chain.getArgs());
            ctx.set("return", chain.getReturn());
            Context _ctx = Lang.context();
            for (String key : msg.keys()) {
                _ctx.set(key, els.get(key).eval(ctx));
            }
            _msg = msg.render(_ctx).toString();
        } else {
            _msg = msg.getOrginalString();
        }
        Sys_log sysLog = Sys_log.c(t, tag, _msg, source);
        if (async)
            sysLogService.async(sysLog);
        else
            sysLogService.sync(sysLog);
    }

最新版的slog代码还在看，感觉要换的话要动很多东西囧
