PSQLException - spring boot 1.4.1 - spring data jpa - offsetdatetime/localdatetime identified as Bytestream

问题

While integrating spring data JPA with postgres. I have a DB table representing the following java object.

private class A {

@Column(name="createdTime", columnDefiniton="TIMESTAMP WITH TIMEZONE")
OffsetDateTime dateTime;
}

I'm trying to save to this table, however, i am getting

Caused by: org.postgresql.util.PSQLException: ERROR: column "created_time" is of type timestamp with time zone but expression is of type bytea
  Hint: You will need to rewrite or cast the expression.

I did notice that postgres jdbc jar has 2 versions of AbstractJdbcStatement & AbstractJdbc42Statement. As postgresql-9.4-1206-jdbc42.jar:9.4 supports JDBC 4.2, im assuming calling the wrong class is causing this exception.

回答1:

Spring data jpa starter 1.4.1.RELEASE uses hibernate 5.0.11. overriding hibernate.version property to the latest version fixed the issues.
