java – 用jackson删除JSON元素

我有一个特定的 JSON节点,对应于import org.codehaus.jackson.JsonNode,而不是
import org.codehaus.jackson.map.JsonNode.

[
    {
        "givenname": "Jim","formattedname": "jimJackson","familyName": null,"middleName": "none","honorificPrefix": "mr","honorificSuffix": "none"
    },{
        "givenname": "john","formattedname": "johnLasher",{
        "givenname": "carlos","formattedname": "carlosAddner","honorifiPrefix": "mr",{
        "givenname": "lisa","formattedname": "liSaray","honorificPrefix": "mrs",{
        "givenname": "bradshaw","formattedname": "bradshawLion",{
        "givenname": "phill","formattedname": "phillKane",{
        "givenname": "Gabriel","formattedname": "gabrielMoosa","honorificSuffix": "none"
    }
]

我想从上述数组的所有JSON节点中删除“familyName”和“middleName”.有没有办法实现这一点？

解决方法

我没有测试过这个,但我觉得这样做会做你想要的：

import org.codehaus.jackson.node.ObjectNode;
// ...
for (JsonNode personNode : rootNode) {
    if (personNode instanceof ObjectNode) {
        ObjectNode object = (ObjectNode) personNode;
        object.remove("familyName");
        object.remove("middleName");
    }
}

您也可以使用Jackon的原始解析API更有效地执行此操作,但代码将会更加复杂.
