mybaits3.4 返回主键失败（Error getting generate?400报错

在项目中进行新增后，根据返回主键在更新数据，但是使用mybaits的主键返回。直接报错了

1.第一种实现方式 ，有人说返回的是一个对象，所以设置keyProperty="对象.字段"

 <insert id="insert" parameterType="cn.com.cathayins.dal.model.DocRecordDO" useGeneratedKeys="true" keyProperty="record.id">
      
    insert into t_doc_record (id, doc_no, product_code, 
      channel_code, schema_code, agreement_print_type, 
      doc_process_cd, doc_inter_method, doc_type_cd, 
      doc_template_code, doc_email_code, doc_path, 
      doc_status_cd, doc_count, gmt_create, is_valid, 
      gmt_modified, tenant_code, doc_xml)
    values (#{id,jdbcType=BIGINT}, #{docNo,jdbcType=VARCHAR}, #{productCode,jdbcType=VARCHAR}, 
      #{channelCode,jdbcType=BIGINT}, #{schemaCode,jdbcType=VARCHAR}, #{agreementPrintType,jdbcType=INTEGER}, 
      #{docProcessCd,jdbcType=TINYINT}, #{docInterMethod,jdbcType=VARCHAR}, #{docTypeCd,jdbcType=TINYINT}, 
      #{docTemplateCode,jdbcType=VARCHAR}, #{docEmailCode,jdbcType=VARCHAR}, #{docPath,jdbcType=VARCHAR}, 
      #{docStatusCd,jdbcType=TINYINT}, #{docCount,jdbcType=INTEGER}, now(), #{isValid,jdbcType=TINYINT}, 
      now(), #{tenantCode,jdbcType=VARCHAR}, #{docXml,jdbcType=LONGVARCHAR})
  </insert>

2.第二种实现方式

 <insert id="insert" parameterType="cn.com.cathayins.dal.model.DocRecordDO" useGeneratedKeys="true" keyProperty="id">
      
    insert into t_doc_record (id, doc_no, product_code, 
      channel_code, schema_code, agreement_print_type, 
      doc_process_cd, doc_inter_method, doc_type_cd, 
      doc_template_code, doc_email_code, doc_path, 
      doc_status_cd, doc_count, gmt_create, is_valid, 
      gmt_modified, tenant_code, doc_xml)
    values (#{id,jdbcType=BIGINT}, #{docNo,jdbcType=VARCHAR}, #{productCode,jdbcType=VARCHAR}, 
      #{channelCode,jdbcType=BIGINT}, #{schemaCode,jdbcType=VARCHAR}, #{agreementPrintType,jdbcType=INTEGER}, 
      #{docProcessCd,jdbcType=TINYINT}, #{docInterMethod,jdbcType=VARCHAR}, #{docTypeCd,jdbcType=TINYINT}, 
      #{docTemplateCode,jdbcType=VARCHAR}, #{docEmailCode,jdbcType=VARCHAR}, #{docPath,jdbcType=VARCHAR}, 
      #{docStatusCd,jdbcType=TINYINT}, #{docCount,jdbcType=INTEGER}, now(), #{isValid,jdbcType=TINYINT}, 
      now(), #{tenantCode,jdbcType=VARCHAR}, #{docXml,jdbcType=LONGVARCHAR})
  </insert>

3.第三种 

 <insert id="insert" parameterType="cn.com.cathayins.dal.model.DocRecordDO">
    <selectKey resultType="java.lang.Long" order="AFTER" keyProperty="id">
          SELECT LAST_INSERT_ID()
      </selectKey> 
      
    insert into t_doc_record (id, doc_no, product_code, 
      channel_code, schema_code, agreement_print_type, 
      doc_process_cd, doc_inter_method, doc_type_cd, 
      doc_template_code, doc_email_code, doc_path, 
      doc_status_cd, doc_count, gmt_create, is_valid, 
      gmt_modified, tenant_code, doc_xml)
    values (#{id,jdbcType=BIGINT}, #{docNo,jdbcType=VARCHAR}, #{productCode,jdbcType=VARCHAR}, 
      #{channelCode,jdbcType=BIGINT}, #{schemaCode,jdbcType=VARCHAR}, #{agreementPrintType,jdbcType=INTEGER}, 
      #{docProcessCd,jdbcType=TINYINT}, #{docInterMethod,jdbcType=VARCHAR}, #{docTypeCd,jdbcType=TINYINT}, 
      #{docTemplateCode,jdbcType=VARCHAR}, #{docEmailCode,jdbcType=VARCHAR}, #{docPath,jdbcType=VARCHAR}, 
      #{docStatusCd,jdbcType=TINYINT}, #{docCount,jdbcType=INTEGER}, now(), #{isValid,jdbcType=TINYINT}, 
      now(), #{tenantCode,jdbcType=VARCHAR}, #{docXml,jdbcType=LONGVARCHAR})
  </insert>

综上， 1,2直接报错。。3没错，但是对象里面的id值仍为null，没有赋值成功

求大神解惑，到底哪方面有问题
