杰克逊的 ObjectMapper 的单个实例不起作用

Question

我正在使用杰克逊的 ObjectMapper 的单个实例，配置反序列化功能在我的应用程序中对未知属性失败是 false。
有时会出现错误

冲突/不明确的属性名称定义（隐式名称 'indskr_indskr_customeraddress_v2id'）：找到多个显式名称：[customeraddressid_v2_id、indskr_indskr_customeraddress_v2id]，还有隐式访问器：[field com.indegene .bulkdata.dto.CustomerAddress#indskr_indskr_customeraddress_v2id][visible=true,ignore=false,explicitName=false]

异常仅出现在开发环境中，无法在我的本地系统中重现。这是零星的问题。

mObjectMapper = new ObjectMapper();
         mObjectMapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);

 private String indskr_indskr_customeraddress_v2id;

@JsonGetter("indskr_indskr_customeraddress_v2id")
    public String getIndskr_indskr_customeraddress_v2id() {
        return indskr_indskr_customeraddress_v2id;
    }
 @JsonSetter("customeraddressid_v2_id")
    public void setIndskr_indskr_customeraddress_v2id(String indskr_indskr_customeraddress_v2id) {
        this.indskr_indskr_customeraddress_v2id = indskr_indskr_customeraddress_v2id;
    }

堆栈跟踪

预期：我不应该得到错误
实际：有时它会抛出错误

Answer 1

检查这部分错误：

找到多个显式名称：[customeraddressid_v2_id, indskr_indskr_customeraddress_v2id]，还有隐式访问器：[field com.indegene.bulkdata.dto.CustomerAddress#indskr_indskr_customeraddress_v2id]

您会注意到有 两个 显式声明，因此您可能在其他地方有一个与 @JsonSetter 冲突的 @JsonProperty 注释。删除额外的注释应该可以解决它。
