我得到 "ERROR: 无法从数据库中获取SequenceInformation，java.sql.SQLException.Numeric Overflow "错误。Numeric Overflow "错误，当我试图创建SessionFactory对象时。我使用的是Java 1.8u74和hibernate 5.4.0版本。我的DB版本是12c。
请帮我解决这个问题。
以下是我的代码。
package suman.examples;
public class Student {
private int ID;
private String NAME;
public int getID() {
return ID;
}
public void setID(int iD) {
ID = iD;
}
public String getNAME() {
return NAME;
}
public void setNAME(String nAME) {
NAME = nAME;
}
}

我会把这个int改成long。
看上去数据类型是long，比int大，所以当赋值发生时，就会有溢出，你的数据就会溢出 SessionFactory 爆炸。请看堆栈跟踪中的这一行。
在oracle.jdbc.driver.GeneratedResultSet.getLong(GeneratedResultSet.java:558)
把类型改成长型，看看你能不能把你的 Hibernate SessionFactory 启动和运行。
