Spring Boot 2和Redshift连接性。

Question

Spring Boot 2和Redshift连接性。

5

我想要将Spring Boot 2与Redshift连接起来，由于Spring Boot 2默认使用HikariCP，而HikariCP没有明确的支持。有人成功连接到Redshift吗？

这是我的Spring Boot 2属性：

spring.datasource.driver-class-name=com.amazon.redshift.jdbc41.Driver
spring.datasource.url=jdbc:redshift://<someHost>.redshift.amazonaws.com:5439/XXX
spring.datasource.username=xxxxxx
spring.datasource.password=xxxxxx


spring.datasource.testWhileIdle = true
spring.datasource.validationQuery = SELECT 1

spring.jpa.show-sql = true
spring.jpa.hibernate.ddl-auto=validate
spring.jpa.properties.hibernate.dialect =  org.hibernate.dialect.PostgreSQL9Dialect

Maven POM.XML

        <dependency>
        <groupId>com.amazon.redshift</groupId>
        <artifactId>redshift-jdbc41</artifactId>
        <version>1.2.10.1009</version>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-jpa</artifactId>
    </dependency>

当我启动服务器时，会出现以下警告和错误：

我有同样的问题。你解决了这个问题吗？ - GarouDan

不，我仍在跟进HikariCP。https://github.com/brettwooldridge/HikariCP/issues/1144 - Sharaf Navas

正如异常所述... RedShift的JDBC驱动程序在createClob方法中进行了检查，并表示不支持某些SQL功能。您应该与亚马逊联系解决此问题。为什么Hibernate会调用它是Hibernate的问题。https://docs.oracle.com/javase/8/docs/api/java/sql/Connection.html#createClob-- - user8558216

我通过添加一个lib文件夹并在pom中指定redshift jar来解决了这个问题。 - Sharaf Navas

实际上，这不是一个异常。这是由LobCreatorBuilderImpl:124生成的日志。这通知您Redshift实现的Connection类不支持createClob()操作。

您可以将spring.jpa.properties.hibernate.jdbc.lob.non_contextual_creation设置为true。

一旦您这样做了，您现在将拥有一个不同的日志，其中显示：

HHH000421：禁用上下文LOB创建，因为hibernate.jdbc.lob.non_contextual_creation为true

这更加清晰。而且您仍然需要处理Redshift无法创建clobs的问题。
