【中文标题】为啥 MySQL 和 JPA 会发生“java.sql.SQLException: Incorrect string value...”【英文标题】：Why "java.sql.SQLException: Incorrect string value..." is happened with MySQL and JPA为什么 MySQL 和 JPA 会发生“java.sql.SQLException: Incorrect string value...” 【发布时间】：2020-07-02 07:14:39 【问题描述】：

我使用以下工具开发 API。

Kotlin 1.3.61 Spring Boot 2.2.4 码头工人 JPA mysql 8.0

应用程序和数据库是使用 docker 构建的。

我尝试使用 UUID 插入数据，但发生了“java.sql.SQLException: Incorrect string value...”。

堆栈跟踪如下。

Hibernate: select todo0_.id as id1_0_0_, todo0_.content as content2_0_0_, todo0_.created_at as created_3_0_0_, todo0_.is_done as is_done4_0_0_, todo0_.updated_at as updated_5_0_0_ from todo todo0_ where todo0_.id=?
Hibernate: insert into todo (content, created_at, is_done, updated_at, id) values (?, ?, ?, ?, ?)

我研究了这个错误，我可以找到说这个原因是字符集的文章。

但我的 my.conf 已经将字符集设置为 utf8mb4 并且数据库变量是 utf8mb4。

我的.conf

[mysqld]
character-set-server=utf8mb4
explicit-defaults-for-timestamp=1
general-log=1
general-log-file=/var/log/mysql/mysqld.log

[client]
default-character-set=utf8mb4

“显示变量如“chara%”的结果；”

+--------------------------+--------------------------------+

我的application.yml没有明确写成字符集，所以我在后面加了“?character_set_server=utf8mb4”。

application.yml

spring:

    active: localhost

将字符集添加到application.yml后，我尝试再次插入，但结果没有改变。

为什么会发生“java.sql.SQLException: Incorrect string value...”？

部分源代码如下。

ddl

CREATE TABLE IF NOT EXISTS `todo_db`.`todo` (
    `id` CHAR(36) NOT NULL,
    `content` VARCHAR(100) NOT NULL,
    `is_done` BOOLEAN,

    `updated_at` DATETIME,
    PRIMARY KEY(`id`)
);

        val createdAt: LocalDateTime?,

        @Column(name = "updated_at")

【问题讨论】：

你已经包含了除了 Java 代码的所有内容，我认为我们也需要看到这一点。检查字符串。它可能包含零值。无论如何，错误消息表明该字符串可能包含垃圾。 @TimBiegeleisen 感谢您的评论。问题区增加了一些代码。 @ThorbjørnRavnAndersen 感谢您的评论。我会检查字符串。总是非常、非常仔细地查看原始异常，即使它可能在堆栈跟踪中很下方。 【参考方案1】：

我有同样的问题，我解决了这个添加到 yml 配置：

以上是关于为啥 MySQL 和 JPA 会发生“java.sql.SQLException: Incorrect string value...”的主要内容，如果未能解决你的问题，请参考以下文章
