Question

我正在尝试使用带有Postgres的Spring Boot Data JDBC构建API。

我有一个简单的pojo，希望写到一张桌子上

：

public final class Test {
   private final String id;
   private final String definition;
}

该表有2列，即varchar id列和jsonb definition列。

使用简单的CRUD存储库保存pojo时，出现以下错误。

ERROR: column "definition" is of type jsonb but expression is of type character varying

通常，解决方案是在application.yml中传递spring.datasourcehikari.connection-properties: stringtype=unspecified，但我无法使它正常工作。

当我激活hikari的调试日志记录时，我可以看到我为其激活的其他设置（例如池名称）

HikariConfig testPool - configuration:
HikariConfig allowPoolSuspension.............false
HikariConfig autoCommit......................true
HikariConfig catalog.........................none
HikariConfig connectionInitSql...............none
HikariConfig connectionTestQuery.............none
HikariConfig connectionTimeout...............30000
HikariConfig dataSource......................none
HikariConfig dataSourceClassName.............none
HikariConfig dataSourceJNDI..................none
HikariConfig dataSourceProperties............{password=<masked>}
HikariConfig driverClassName................."org.postgresql.Driver"
HikariConfig healthCheckProperties...........{}
HikariConfig healthCheckRegistry.............none
HikariConfig idleTimeout.....................600000
HikariConfig initializationFailTimeout.......1
HikariConfig isolateInternalQueries..........false
HikariConfig jdbcUrl.........................jdbc:postgresql://localhost/test
HikariConfig leakDetectionThreshold..........0
HikariConfig maxLifetime.....................1800000
HikariConfig maximumPoolSize.................10
HikariConfig metricRegistry..................none
HikariConfig metricsTrackerFactory...........none
HikariConfig minimumIdle.....................10
HikariConfig password........................<masked>
HikariConfig poolName........................"testPool"
HikariConfig readOnly........................false
HikariConfig registerMbeans..................false
HikariConfig scheduledExecutor...............none
HikariConfig schema..........................none
HikariConfig threadFactory...................internal
HikariConfig transactionIsolation............default
HikariConfig username........................"test"
HikariConfig validationTimeout...............5000
HikariDataSource testPool - Starting...
HikariPool testPool - Added connection org.postgresql.jdbc.PgConnection@49ba49a7
HikariDataSource testPool - Start completed.

这是我的application.yml：

spring:
  datasource:
    url: jdbc:postgresql://localhost/test
    username: test
    hikari:
      connection-properties: stringtype=unspecified
      poolName: testPool
logging.level.com.zaxxer.hikari: DEBUG

有什么想法吗？

编辑：

这是存储库界面：

@Repository
interface TestRepository extends org.springframework.data.repository.<Test, String>{
}

我认为您需要使用以下属性文件中的data-source-properties

spring.datasource.hikari.data-source-properties = stringtype =未指定

然后在“定义”的getter上方添加两个注释。

@基本 @Enumerated（EnumType.STRING）公共字符串getDefinition（）{ 返回定义； }
