expr string sso pub ant other sof rom pos 1.在實體上使用@Table 註解 默認不加使用駝峰轉下劃線匹配
@Table(name="table_name")
public class Entity{
}2.實現 IDynamicTableName 接口
public class Entity implements IDynamicTableName{ @Override public String getDynamicTableName() { return “tableName”; } } 可以直接添加一個非數據庫字段 使用 @Transient 註解 外部直接設置表名 @Transient private String tableName; @Override public String getDynamicTableName() { return tableName; } IDynamicTableName 源碼定義： /*
