es做分页查询的时候，我设置的每页显示10条数据，如果我查询出来的数据小于10条，返回的数据为什么会是空数据呢

初步怀疑是不是不支持嵌套,数组啥的呀
然后我就翻了翻源码,发现了这个
我的错误就是在最后一个else里出现的
仔细一看,发现这个地方循环只要走了两次,或者前面的条件不成立就肯定会抛这个异常,这怎么看上去像是有点问题呢
@SuppressWarnings("unchecked")
Object extractFromSource(Map<String, Object> map) {
Object value = map;
boolean first = true;
// each node is a key inside the map
for (String node : path) {
if (value == null) {
return null;
} else if (first || value instanceof Map) {
first = false;
value = ((Map<String, Object>) value).get(node);
} else {
throw new SqlIllegalArgumentException("Cannot extract value [{}] from source", fieldName);
}
}
return unwrapMultiValue(value);
}es启动报:unknown setting [network.hosts] 不知是哪里配置的问题,求助
