could not be found for the javaType (java.util.List) : jdbcType (null) combination.

• Jave

问题描述： Type handler was null on parameter mapping for property ‘gyWarehouseCode’. It was either not specified and/or could not be found for the javaType (java.util.List) : jdbcType (null) combination.

解决方案1：如果属性’gyWarehouseCode’的java类型为java.util.List，请确保指定了正确的jdbcType。

  INSERT INTO your_table (gyWarehouseCode) VALUES
  
    (#{code, jdbcType=VARCHAR})

解决方案2：在java对应的实体类对应的字段上加上(typeHandler = JacksonTypeHandler.class)这个注解

@TableField(typeHandler = JacksonTypeHandler.class)

private List  gyWarehouseCode
