MybatisPlus中如何调用Oracle存储过程

create table OLD_USER
(
  USER_ID                    NUMBER(6) not null primary key,
  LOGIN_NAME                 VARCHAR2(100) not null,
  REAL_NAME                  VARCHAR2(300),
  PASSWORD                   CHAR(64)
)

create table NEW_USER
(
  ID            NUMBER(11) not null primary key,
  CREATE_TIME   TIMESTAMP(6),
  UPDATE_TIME   TIMESTAMP(6),
  DELETED       NUMBER(1),
  ACCOUNT       VARCHAR2(255),
  USERNAME      VARCHAR2(255),
  PASSWORD      VARCHAR2(255)
)
