@JSONField 枚举序列化 栈溢出

[linxinqiang90]

版本:1.2.72,1.2.73,1.2.75
枚举中只有一个值，并且被@JSONField，序列化时溢出
枚举2个值以上，序列化正常。

@Data
public class TestEntity {
    private TestEnum testEnum;
    private String testName;
}

public enum TestEnum {
    @JSONField(name = "xx")
    test1("1");
//    @JSONField(name = "xx2")
//    test2("2");
    private String title;

    private TestEnum(String title) {
        this.title = title;
    }

}

   public static void main(String[] args) {
        TestEntity testEntity = new TestEntity();
        testEntity.setTestName("xxxx");
        testEntity.setTestEnum(TestEnum.test1);
        System.out.println(JSON.toJSONString(testEntity));
    }
