package cn.silvernet.util;

import java.io.Serializable;

public class KeyUtils implements IdentifierGenerator,Configurable {

public String classname;
@Override

}

@Override

}

}

添加数据输出

CATALOG---null

IDENTIFIER_NORMALIZER---null

PK---id

SCHEMA---null

TABLE---t_info

TABLES---t_info

ENTITY_NAME---cn.silvernet.model.Info

JPA_ENTITY_NAME---Info

---------------------------------------

CATALOG---null

IDENTIFIER_NORMALIZER---null

PK---id

SCHEMA---null

TABLE---t_info

TABLES---t_info

ENTITY_NAME---cn.silvernet.model.Info

JPA_ENTITY_NAME---Info

---------------------------------------

Hibernate: insert into t_info (date, type, title, content, id) values (?, ?, ?, ?, ?)
