Question

将spring数据JPA与postgres集成在一起。我有一个表示以下java对象的数据库表。

private class A {

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

我正在尝试保存到此表，但是，我正在

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.

我注意到postgres jdbc jar有2个版本的AbstractJdbcStatement ＆安培; AbstractJdbc42Statement。由于postgresql-9.4-1206-jdbc42.jar：9.4支持JDBC 4.2，我假设调用错误的类导致此异常。

PSQLException - spring boot 1.4.1 - spring data jpa - offsetdatetime / localdatetime标识为Bytestream
