我正在尝试序列化递归 Map 和Jackson在一起 RuntimePermission 访问异常。以下是堆栈跟踪：

递归类型定义为：

public class FilterTree extends TreeMap<String, FilterTree> {
}

对象正在序列化，如下所示：

Map<Integer, FilterTree> tree = new TreeMap<>(Collections.reverseOrder());
tree.put(0, new FilterTree());

ObjectMapper mapper = new ObjectMapper();
String jsonStr = mapper.writeValueAsString(tree); // here lies the exception

有什么我明显做错的吗？

jackson库在序列化递归数据结构方面没有任何问题。
我正在使用以下库

compile group: 'com.fasterxml.jackson.core', name: 'jackson-core', version: '2.8.5'
compile group: 'com.fasterxml.jackson.core', name: 'jackson-databind', version: '2.8.5'

我能够序列化您提供的类似数据结构。参见下面的代码

public class Test {

static class FilterTree extends TreeMap<String, FilterTree> {
}

public static void main(String[] args) throws JsonProcessingException {
    Map<Integer, FilterTree> tree = new TreeMap<>(Collections.reverseOrder());
    FilterTree childTree = new FilterTree();
    childTree.put("aaa", new FilterTree());
    childTree.put("bbb", new FilterTree());
    childTree.get("bbb").put("ccc", new FilterTree());
    tree.put(0, childTree);

    ObjectMapper mapper = new ObjectMapper();
    String jsonStr = mapper.writeValueAsString(tree);
    System.out.println(jsonStr);
}

}
我得到的结果是

{"0":{"aaa":{},"bbb":{"ccc":{}}}}

所以我不认为Jackson图书馆有任何问题。
从您提供的堆栈跟踪来看，似乎您正在使用 elastic-search plugin 检查以下内容
你用的是什么版本的Jackson？
jackson库是否捆绑在elasticsearch插件中？如果是，那么elasticsearch是否为对象Map器或json序列化提供任何配置？
被序列化的字段不是私有的/受保护的，可以访问。
另外，如果您使用的是旧版本的ElasticSearch插件，您可以尝试升级该版本，看看它是否解决了问题
我发现很少有类似的问题像你报道的那样。。检查它们是否有任何帮助（尽管它们是一些老问题。。（2017年起）
