我有一个物体。我正在尝试将我的对象转换为hashmap。如下所示:
@XmlRootElement
@XmlType(propOrder = {"isIdAvail","isFrndAvail","otherDetails"})
@XmlAccessorType(XmlAccessType.FIELD)
public class MyObject implements Serializable {
private boolean isIdAvail;
private boolean isFrndAvail;
private List<OtherDetails> otherDetails;
//getters and Setters
}
我将上述对象作为响应,我正尝试将其转换为Map,如下所示:
HashMap<String, Object> result;
result = new ObjectMapper().setDefaultPropertyInclusion(
JsonInclude.Value.construct(Include.ALWAYS,
Include.NON_NULL)).convertValue(response, HashMap.class);
上述程序的输出为:
{
"isIdAvail": true,
"isFrndAvail": true,
"otherDetails": [
{}
]
}
当尝试将上述对象响应转换为Hashmap时,即使我有NON_NUL,我也会收到以下异常:
java.lang.IllegalArgumentException: (was java.lang.NullPointerException) (through reference chain: com.myproject.org.bump.tref.model.FullDetailsResponse["fullOtherDetails"]->java.util.ArrayList[0]->com.myproject.org.bump.tref.model.FullOtherDetails["otherDetails"]->java.util.ArrayList[0]->com.myproject.org.bump.tref.model.FullDetailsResponse["otherLineId"])
在这里,任何建议都非常有用,因为浪费了很多其他类似的线程,其中包括我已经在做的了NON_NULL。 提前致谢。请问有人有什么想法吗?
