1.在實(shí)體上使用@Table 注解 默認(rèn)不加使用駝峰轉(zhuǎn)下劃線匹配

@Table(name="table_name")
public class Entity{

}

2.實(shí)現(xiàn) IDynamicTableName 接口

public class Entity   implements IDynamicTableName{

@Override
public String getDynamicTableName() {

    return “tableName”;
}
}

可以直接添加一個(gè)非數(shù)據(jù)庫(kù)字段 使用 @Transient 注解  外部直接設(shè)置表名

 @Transient 
    private String tableName;

@Override
public String getDynamicTableName() {

    return  tableName;
}
