Java获取Oracle数据库序列值

import javax.sql.DataSource;

import org.springframework.jdbc.support.incrementer.OracleSequenceMaxValueIncrementer;

import com.sinotrans.framework.core.util.ContextUtils;

public class OracleSequence {
private static DataSource ds = null;

//静态初始化一个数据源
static {
if (ds == null)
ds = (DataSource) ContextUtils.getBean("dataSource");
}
//定义静态方法
public static String getNextVal(String seqName) {
OracleSequenceMaxValueIncrementer incr = new OracleSequenceMaxValueIncrementer(ds, seqName);
return incr.nextStringValue();
}
//定义静态方法
public static Long getNextValLong(String seqName) {
OracleSequenceMaxValueIncrementer incr = new OracleSequenceMaxValueIncrementer(ds, seqName);
return incr.nextLongValue();
}
}
