Error attempting to get column 'createDate' from result set.

• 换用高版本的druid数据源

springboot项目，关于InvalidDataAccessApiUsageException: Error attempting to get column ‘createTime’ from result set. Cause: java.sql.SQLFeatureNotSupportedException ; null; nested exception is java.sql.SQLFeatureNotSupportedException的解决办法。

swagger测试接口报错：

{
  "timestamp": "2021-05-03T06:49:19.496+00:00",
  "status": 500,
  "error": "Internal Server Error",
  "message": "",
  "path": "/system/cfg/pos/"
}

后端控制台报错：

 Error attempting to get column 'createDate' from result set.  Cause: java.sql.SQLFeatureNotSupportedException
; null; nested exception is java.sql.SQLFeatureNotSupportedException] with root cause

java.sql.SQLFeatureNotSupportedException: null
	at com.alibaba.druid.pool.DruidPooledResultSet.getObject(DruidPooledResultSet.java:1771) ~[druid-1.1.10.jar:1.1.10]
	at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) ~[na:1.8.0_152]
	

报错原因

因为我在项目中使用了Mybati-plus，同时使用了druid数据源，由于druid数据源的版本太低，不支持JDK8中的LocalDate、LocalTime、LocalDateTime等日期类型，所以解决方案就是下载新版本的druid依赖。

解决方法

换用版本高于或等于1.1.21以上的jar包

<!--druid 数据源-->
<dependency>
    <groupId>com.alibaba</groupId>
    <artifactId>druid-spring-boot-starter</artifactId>
    <version>1.1.21</version>
</dependency>

换用高版本的druid数据源

[
  {
    "id": 1,
    "name": "技术总监",
    "createDate": "2020-03-31",
    "enabled": true
  },
  {
    "id": 2,
    "name": "运营总监",
    "createDate": "2020-03-31",
    "enabled": true
  },
  {
    "id": 3,
    "name": "市场总监",
    "createDate": "2020-03-31",
    "enabled": true
  },
  {
    "id": 4,
    "name": "研发工程师",
    "createDate": "2020-03-31",
    "enabled": true
  },
  {
    "id": 5,
    "name": "运维工程师",
    "createDate": "2020-03-31",
    "enabled": true
  }
]

完美解决！！！！
