我有一个现有对象，想使用 Java + POJO 编解码器在 MongoDB 中序列化。由于某种原因，驱动程序尝试创建枚举实例而不是使用 valueOF：

org.bson.codecs.configuration.CodecConfigurationException: Failed to decode 'phase'. Failed to decode 'value'. Cannot find a public constructor for 'SimplePhaseEnumType'.
at org.bson.codecs.pojo.PojoCodecImpl.decodePropertyModel(PojoCodecImpl.java:192)
at org.bson.codecs.pojo.PojoCodecImpl.decodeProperties(PojoCodecImpl.java:168)
at org.bson.codecs.pojo.PojoCodecImpl.decode(PojoCodecImpl.java:122)
at org.bson.codecs.pojo.PojoCodecImpl.decode(PojoCodecImpl.java:126)
at com.mongodb.operation.CommandResultArrayCodec.decode(CommandResultArrayCodec.java:52)

枚举：

public enum SimplePhaseEnumType {

PROPOSED("Proposed"),
INTERIM("Interim"),
MODIFIED("Modified"),
ASSIGNED("Assigned");
private final String value;

SimplePhaseEnumType(String v) {
    value = v;
}

public String value() {
    return value;
}

public static SimplePhaseEnumType fromValue(String v) {
    for (SimplePhaseEnumType c: SimplePhaseEnumType.values()) {
        if (c.value.equals(v)) {
            return c;
        }
    }
    throw …
