Spring 数据 r2dbc 错误 - 截断不正确的 DOUBLE 值

Question

我正在使用 Spring 数据 r2dbc 并面临一个奇怪的问题。

implementation 'org.springframework.boot:spring-boot-starter-data-r2dbc'
runtimeOnly 'dev.miku:r2dbc-mysql'
runtimeOnly 'mysql:mysql-connector-java'

更新查询出错。

@Modifying
@Query("UPDATE appt SET notes = :newNotes WHERE appt_id = :apptId AND org_id = :orgId")
Mono<Integer> updateAppt(long apptId, int orgId, String newNotes);

错误：-

通过 SQL 工作台查询工作正常。

UPDATE appt SET notes = 'Test create Appointment - Updated' WHERE appt_id = 1 AND org_id = 2;

Answer 1

当他们解释查询方法时，请注意 Spring 数据 R2DBC 文档中的第二个信息提示：

R2DBC 存储库内部使用Statement.bind(…)按索引将参数绑定到占位符。

请尝试将您的方法定义为：

@Modifying
@Query("UPDATE appt SET notes = :newNotes WHERE appt_id = :apptId AND org_id = :orgId")
Mono<Integer> updateAppt(String newNotes, long apptId, int orgId);

请注意参数顺序的变化。

MySQL 显然在抱怨将'Test create Appointment - Updated'值用作数字。
