我尝试使用this tutorial将Apache OFBiz从derby迁移到mysql。在entityengine.xml进行更改之前，我使用defaultData执行了ofbiz，并将数据从webtools导出到xml文件中。之后，我做了所有上述更改，创建了工作的db模式和用户。但是当我在这些更改后运行ofbiz时，我收到了一条带有消息的例外
`invalid delegator name!`
为什么？我目前正在使用16.011版本的OFBiz。以下是我的委托人和数据源的样子

最近改变了Apache OFBiz包结构，提到的tuturial并不完全是最新的。我改变了“org.ofbiz”。条目“org.apache.ofbiz”。在教程中。
请再试一次并报告现在是否适合您。

（我使用OFBiz版本16.11.02，此时为最新版本）
为数据库创建用户：
create database ofbiz;
create database ofbizolap;
create database ofbiztenant;
use mysql;
select database();
create user ofbiz@localhost;
create user ofbizolap@localhost;
create user ofbiztenant@localhost;
UPDATE mysql.user
SET authentication_string = PASSWORD('ofbiz'), password_expired = 'N'
WHERE User = 'ofbiz' AND Host = 'localhost';
FLUSH PRIVILEGES;
UPDATE mysql.user
SET authentication_string = PASSWORD('ofbizolap'), password_expired = 'N'
WHERE User = 'ofbizolap' AND Host = 'localhost';
FLUSH PRIVILEGES;
UPDATE mysql.user
SET authentication_string = PASSWORD('ofbiztenant'), password_expired = 'N'
WHERE User = 'ofbiztenant' AND Host = 'localhost';
FLUSH PRIVILEGES;
grant all privileges on *.* to 'ofbiz'@localhost identified by 'ofbiz';
grant all privileges on *.* to 'ofbizolap'@localhost identified by 'ofbizolap';
grant all privileges on *.* to 'ofbiztenant'@localhost identified by 'ofbiztenant';
使用端口号，默认，它是3306
jdbc-uri="jdbc:mysql://127.0.0.1:3306/ofbiz?autoReconnect=true"
找到单词derby，将其更改为mysql。
然后
gradlew cleanAll --info
gradlew loadDefault --info
gradlew ofbiz --info
