当尝试连接 mirthconnect 以使用 mariaDB 而不是 Derby 嵌入式数据库时,创建数据库时 mirth connect 失败。

使用:

  • Ubuntu 18.04 LTS
  • MariaDB 10.1.29-MariaDB-6
  • 欢乐连接 3.6.0
  • Java openjdk 10.0.1

设置步骤:

  1. 安装玛丽亚数据库
  2. 安装 Mirth 连接。
  3. 创建要与 Mirth 一起使用的数据库
  4. 在 Maria DB 中创建 mirth 用户
  5. 配置 mirth connect 以连接到 Maria DB
  6. 开始欢乐服务

启动 mirthconnect 服务时,会引发以下异常。

已创建一半的数据库表

show tables;
+------------------------+
| Tables_in_mirthconnect |
+------------------------+
| CHANNEL                |
| EVENT                  |

| SCHEMA_INFO            |
| SCRIPT                 |

谁能告诉我:

  • 例外意味着什么?
  • 如何解决错误?

有问题的错误

Caused by: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Specified key was too long; max key length is 767 bytes

似乎与密钥长度有关 - 数据库默认字符集是 utf16 而不是 utf8,因此由于字符大小(以字节为单位),其中一张表的密钥大小实际上大于 767 字节。

为 mirth 创建数据库时 - 确保字符集设置为 UTF8

create database mirthconnect character set utf8 collate utf8_general_ci;
