このプロパティをapplication.propertiesに追加します。

spring.jpa.properties.hibernate.jdbc.lob.non_contextual_creation=true

参照 ：

同様の問題がありました。私はこの解決策に従い、それは私のために働いた

http://vkuzel.blogspot.com/2016/03/spring-boot-jpa-hibernate-atomikos.html

# Disable feature detection by this undocumented parameter. Check the org.hibernate.engine.jdbc.internal.JdbcServiceImpl.configure method for more details.
spring.jpa.properties.hibernate.temp.use_jdbc_metadata_defaults = false

# Because detection is disabled you have to set correct dialect by hand.
spring.jpa.database-platform=org.hibernate.dialect.PostgreSQL9Dialect

これはHibernate当時の問題であり、回避策として次のフラグを使用できます。プロパティで次の構成を設定します。

spring.jpa.properties.hibernate.jdbc.lob.non_contextual_creation=true

以下のための春のブート2.xxのこのフラグ単に無効文脈LOBの作成ができますが、本当に適切にチェック答えを知りたい場合はUPDATE V1を。

更新されたV1

これはHibernateの問題でした。が 含まれる2.0.xまでの最新バージョンのSpring Bootを使用している場合は、こちらをご覧ください。この問題は5.4.0.CR1で修正されているため、その依存関係を追加する必要があります。2.1.xHibernate 5.3.10.finalHibernate version

Gradleの場合：

compile('org.hibernate:hibernate-core:5.4.2.Final')

Mavenの場合：

<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-core</artifactId>
    <version>5.4.2.Final</version>
</dependency>

V2「SPRING BOOT 2.2.0.M（1-4）」を更新しました

さらにSpring boot v2.2.0.Mx、現在Hibernate v5.4.xこの問題はこれらのバージョンで修正されています。

hibernate.propertiesを追加して解決

hibernate.jdbc.lob.non_contextual_creation=true

の他のソリューションは機能application.propertiesしませんでした。これは、XML hibernate.cfg.xmlでも実行できます。

Spring Bootバージョン：2.0.2.RELEASE

次のYaml構成を使用して解決します。

spring:
  jpa:
    properties:
      hibernate:
        jdbc:
          lob:
            non_contextual_creation: true
    database-platform: org.hibernate.dialect.PostgreSQL9Dialect

spring:      
  jpa:
    properties:
      hibernate:
        temp:
          use_jdbc_metadata_defaults: false
        jdbc:
          lob:
            non_contextual_creation: true

use_jdbc_metadata_defaults：falseまたはnon_contextual_creation：true 2つのアイテムが正常に機能します

Spring Bootバージョン：2.1.x.RELEASEでも同じ問題に直面しました。それは働いた：

spring.jpa.properties.hibernate.jdbc.lob.non_contextual_creation=true 

私はこのことで一日苦労していました。

• 春のブーツバージョン 2.2.5

• Postgres： 42.2.10

• サーバー上のPostgresのバージョン： PostgreSQL 11.6 on x86_64-pc-linux-gnu, compiled by gcc (GCC) 4.9.3, 64-bit

Hibernate構成でSpring JPAデータを使用していました。sessionFactoryを使用します。

ハイバネート構成：

@Bean(name = "sessionFactory")
@Primary
public LocalSessionFactoryBean sessionFactory(){
    LocalSessionFactoryBean sessionFactoryBean = new LocalSessionFactoryBean();
    sessionFactoryBean.setDataSource(assetHealthDataSource);
    sessionFactoryBean.setMappingDirectoryLocations(new Resource[]{new ClassPathResource("mappings")});
    sessionFactoryBean.setHibernateProperties(hibernateProperties());

    return sessionFactoryBean;
}

休止状態のプロパティ：

private final Properties hibernateProperties() {
    Properties hibernateProperties = new Properties();
    hibernateProperties.setProperty(
            "hibernate.dialect", "org.hibernate.dialect.PostgreSQL9Dialect");
    hibernateProperties.setProperty(
            "hibernate.jdbc.lob.non_contextual_creation", "true");
    hibernateProperties.setProperty(
            "hibernate.temp.use_jdbc_metadata_defaults", "false");
    hibernateProperties.setProperty(
            "hibernate.show_sql", environment.getProperty("assetHealthDataSource.hibernate.showSQL"));
    hibernateProperties.setProperty(
            "hibernate.format_sql", environment.getProperty("assetHealthDataSource.hibernate.formatSQL"));
    hibernateProperties.setProperty(
            "hibernate.transaction.auto_close_session", "false");
    hibernateProperties.setProperty(
            "hibernate.hibernate.connection.release_mode", "auto");
    hibernateProperties.setProperty(
            "hibernate.hikari.maximumPoolSize", "3");
    hibernateProperties.setProperty(
            "hibernate.default_schema", "MY_SCHEMA");

    return hibernateProperties;
}

しかし、すべてが適切に機能していませんでした。これを解決するのを助けることができるどんな提案でも喜んで見てください。どうもありがとうございました。
