Map<String,Map<String,Object>> |
SequenceDataSourceHolder.getSequenceRecordByName(String selectSql,
String minValueColumnName,
String maxValueColumnName,
String innerStepColumnName,
String sequenceName)
根据sequenceName 获取当前db里的指定sequence记录的各字段值
|
void |
MultipleSequence.init()
初始化各个数据源的sequence，如果不存在记录就插入一条到db
|
void |
SequenceDataSourceHolder.initSequenceRecord(int index,
String sequenceName,
int innerStep,
int outStep,
long minValue,
long maxValue,
String valueColumnName)
初始化sequence 记录，如果db里存在该记录就跳过；否则对此进行初始化
|
void |
MultipleSequenceDao.initSequenceRecord(String sequenceName,
long minValue,
long maxValue,
int innerStep)
初始化sequence的初始值,每个数据源都要去检查一遍，如果不存在就插入一条记录
