Fasterxml Jackson自动将非布尔值转换为布尔值

假设您将布尔字段映射为对象类型（有HARDI回答）有两种方法：

1.自定义设置方法 -

    public class DTO {    String key1;    Object booleanKey;    public Object getBooleanKey() {        return booleanKey;    }    public void setBooleanKey(Object booleanKey) {        if (booleanKey instanceof Boolean) { this.booleanKey = booleanKey;        } else { // custom pre here        }    }    public String getKey1() {        return key1;    }    public void setKey1(String key1) {        this.key1 = key1;    }    }

2.编写自定义反序列化器-

class BooleanKeyDeserializer extends JsonDeserializer<Object> {@Overridepublic Object deserialize(JsonParser p, DeserializationContext ctxt) throws IOException, JsonProcessingException {    Object object = p.readValueAs(Object.class);    if (!(object instanceof Boolean)) {        // custom pre here    }    return object;}}

注释您要对其执行自定义反序列化的字段-

class DTO {String key1;@JsonDeserialize(using = BooleanKeyDeserializer.class)Object booleanKey;//setters getters}
