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.
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.
