Hibernate整合postgresql出错

环境

Spring Boot + JPA + Hibernate + Postgresql

问题

启动时抛出异常：

java.lang.reflect.InvocationTargetException: null
	at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) ~[na:1.8.0_201]
	at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) ~[na:1.8.0_201]

	......

找到关键代码如下：

final Class connectionClass = Connection.class;
Method createClobMethod = connectionClass.getMethod( "createClob", NO_ARG_SIG );
if ( createClobMethod.getDeclaringClass().equals( Connection.class ) ) {
	// If we get here we are running in a jdk 1.6 (jdbc 4) environment...
	// Further check to make sure the driver actually implements the LOB creation methods.  We
	// check against createClob() as indicative of all; should we check against all 3 explicitly?
	try {
		Object clob = createClobMethod.invoke( jdbcConnection, NO_ARGS );

Hibernate尝试调用Connection.createClob方法时抛出空指针异常，原因是postgresql不支持Lob操作，所以其实现的driver中就没有createClob方法的实现。

解决方案

Postgreqsql和Hibernate二选一
