问答 syslog 记录错误信息该怎么记录？

@Slog(tag="编辑用户", after="用户名={args[0].loginname},新用户信息=${args[0]},编辑结果=${re.msg}")

这个是正常的 ，如果出现错误的时候我该怎么记录了，我想把堆栈错误信息记录到数据库中

@Slog(tag="编辑用户", after="用户名={args[0].loginname},新用户信息=${args[0]},编辑结果=${re.msg}" error="${e}")

这样写貌似没啥效果啊，另外我想把错误专门进行分类便于查找错误改怎么改？

注册个el方法，把e传进去，返回堆栈信息

我这样写的不行

@At("/addDo")
	@Ok("json")
	@RequiresPermissions("sys:area:save")
	@Slog(tag="添加地区", after="地区信息=${args[0]},添加结果=${re.msg}", error="错误原因为${e}")
	public Object addDo(@Param("area") Area area) {
		try {
			int i = 1/0;
			if (!Strings.isBlank(area.getName())) {
				Area a = areaService.fetch(Cnd.where("name", "=",area.getName()));
				if (a != null)
					return Result.error("sys.area.duplicate");
			}
			area.setOpBy(getUserId());
			area.setOpAt((int) (System.currentTimeMillis() / 1000));
			areaService.insertArea(area);
			return Result.success("system.success");
		} catch (Exception e) {
			return Result.error("system.error");
		}
	}

看nutz more中是这样说的
args 方法参数
re 方法返回值,仅 after时可用
e 异常对象,仅error时可用
req 请求对象,仅mvc请求作用域内可用
resp 响应对象,仅mvc请求作用域内可用
方法参数 依赖ecj或jdk8的-paramters编译选项.
是有异常对象e的捏。

是报错还是怎样?

看你的代码, 不像有异常抛出去呢?

int i = 1/0; runtime异常啊 我看了下 因为slog是以前的代码 没有捕获异常，所以没有e,现在更新为最新的，应该没问题。

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

doLog("aop.error", error, chain, e); 貌似没有执行 ，我像外抛异常也没有进入filter的catch里面去

进这个filter方法没

进入了filter方法啊 但是不会进入catch里面去

那就是你的方法没抛出异常啊

抛了异常啊 

@At("/addDo")
	@Ok("json")
	@RequiresPermissions("sys:area:save")
	@Slog(tag="添加地区", after="地区信息=${args[0]},添加结果=${re.msg}", error="错误原因为${e}")
	public Object addDo(@Param("area") Area area) throws Exception{
		try {
			int i = 1/0;
			if (!Strings.isBlank(area.getName())) {
				Area a = areaService.fetch(Cnd.where("name", "=",area.getName()));
				if (a != null)
					return Result.error("sys.area.duplicate");
			}
			area.setOpBy(getUserId());
			area.setOpAt((int) (System.currentTimeMillis() / 1000));
			areaService.insertArea(area);
			return Result.success("system.success");
		} catch (Exception e) {
			return Result.error("system.error");
		}
	}

这样写有错吗？

被catch了, 拦截器又怎么能catch到呢?

} catch (Exception e) {

这个不try cach我前台又没办法给提示啊。

难道我日志打到service层 然后再controller里面try catch?

是的, 业务逻辑放在service层嘛
