使用 c3p0 休眠：createClob() 尚未实现
hibernate with c3p0: createClob() is not yet implemented
在我的项目中，我开始使用 c3p0 和 hibernate 来重新连接到数据库，因为 hibernate 不会在数据库失败时恢复连接。
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-c3p0</artifactId>
<version>5.2.9.Final</version>
</dependency>
我使用的是休眠版本：
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-core</artifactId>
<version>5.2.9.Final</version>
</dependency>
postgresql 驱动程序是：
<dependency>
<groupId>org.postgresql</groupId>
<artifactId>postgresql</artifactId>
<version>42.1.4</version>
</dependency>
c3p0配置为：
properties.put("hibernate.c3p0.preferredTestQuery","SELECT 1");
properties.put("hibernate.c3p0.testConnectionOnCheckout","true");
properties.put("hibernate.c3p0.acquireRetryAttempts","1");
properties.put("hibernate.c3p0.acquireIncrement","1");
properties.put("hibernate.c3p0.idleConnectionTestPeriod","60");
但我不断收到此错误：

我必须注意，我不是在给 createClob() 打电话！
那么在 Tomcat 7 启动期间我应该更改什么以消除此错误？我还从 tomcat 的 lib 目录中删除了 postgresql 驱动程序。
在您的 persistence.xml
上设置 hibernate.jdbc.lob.non_contextual_creation=true
以防万一有人在搜索 postgresql 等效错误时发现此线程：
java.sql.SQLFeatureNotSupportedException: Method org.postgresql.jdbc.PgConnection.createClob() is not yet implemented.
application.properties:
# disable driver's feature detection
spring.jpa.properties.hibernate.temp.use_jdbc_metadata_defaults = false
# without detection you have to set the dialect by hand
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.PostgreSQLDialect
顺便说一句：Spring Boot 2.0.0.RELEASE 使用损坏的 postgresql 驱动程序版本，我必须指定 42.2.0 以便完全加载驱动程序：
Caused by: java.lang.RuntimeException: Failed to load driver class org.postgresql.Driver in either of HikariConfig class loader or Thread context classloader
更新 2018-03-01：
根据这个问题，Stacktrace 被认为是一个警告，可以忽略
https://github.com/spring-projects/spring-boot/issues/12007#issuecomment-369388646
更新 2018-03-13：
现在有一个官方错误报告：
https://hibernate.atlassian.net/browse/HHH-12368
在 Spring 引导中，在 application.properties 上设置此 属性 修复问题：
spring.jpa.properties.hibernate.jdbc.lob.non_contextual_creation=true
在我的项目中，我开始使用 c3p0 和 hibernate 来重新连接到数据库，因为 hibernate 不会在数据库失败时恢复连接。
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-c3p0</artifactId>
<version>5.2.9.Final</version>
</dependency>
我使用的是休眠版本：
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-core</artifactId>
<version>5.2.9.Final</version>
</dependency>
postgresql 驱动程序是：
<dependency>
<groupId>org.postgresql</groupId>
<artifactId>postgresql</artifactId>
<version>42.1.4</version>
</dependency>
c3p0配置为：
properties.put("hibernate.c3p0.preferredTestQuery","SELECT 1");
properties.put("hibernate.c3p0.testConnectionOnCheckout","true");
properties.put("hibernate.c3p0.acquireRetryAttempts","1");
properties.put("hibernate.c3p0.acquireIncrement","1");
properties.put("hibernate.c3p0.idleConnectionTestPeriod","60");
但我不断收到此错误：

我必须注意，我不是在给 createClob() 打电话！
那么在 Tomcat 7 启动期间我应该更改什么以消除此错误？我还从 tomcat 的 lib 目录中删除了 postgresql 驱动程序。
在您的 persistence.xml
hibernate.jdbc.lob.non_contextual_creation=true
以防万一有人在搜索 postgresql 等效错误时发现此线程：
java.sql.SQLFeatureNotSupportedException: Method org.postgresql.jdbc.PgConnection.createClob() is not yet implemented.
application.properties:
# disable driver's feature detection
spring.jpa.properties.hibernate.temp.use_jdbc_metadata_defaults = false
# without detection you have to set the dialect by hand
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.PostgreSQLDialect
顺便说一句：Spring Boot 2.0.0.RELEASE 使用损坏的 postgresql 驱动程序版本，我必须指定 42.2.0 以便完全加载驱动程序：
Caused by: java.lang.RuntimeException: Failed to load driver class org.postgresql.Driver in either of HikariConfig class loader or Thread context classloader

根据这个问题，Stacktrace 被认为是一个警告，可以忽略

更新 2018-03-13：
现在有一个官方错误报告： https://hibernate.atlassian.net/browse/HHH-12368
在 Spring 引导中，在 application.properties 上设置此 属性 修复问题：
spring.jpa.properties.hibernate.jdbc.lob.non_contextual_creation=true
