我有2个aplications和2个数据库。它们几乎是一样的。它实际上是2个电话簿。一个被称为电话簿其他电话簿2。还有2个数据库，phonebookdb和phonebookdb2。我使用Spring和Hibernate。我可以配置什么，这样可以工作。 我在context.xml中完成了这个：
<Resource name="jdbc/phonebookdb" auth="Container"
type="javax.sql.DataSource"
username="root" password=""
driverClassName="com.mysql.jdbc.Driver"
url="jdbc:mysql://localhost:3306/phonebookdb?useUnicode=true&characterEncoding=UTF-8"
maxActive="100" maxIdle="30" maxWait="10000" />
<Resource name="jdbc/phonebookdb2" auth="Container"
type="javax.sql.DataSource"
username="root" password=""
driverClassName="com.mysql.jdbc.Driver"
url="jdbc:mysql://localhost:3306/phonebookdb2?useUnicode=true&characterEncoding=UTF-8"
maxActive="100" maxIdle="30" maxWait="10000" />
<Resource auth="Container" driverClassName="com.mysql.jdbc.Driver" maxActive="100" maxIdle="30" maxWait="10000" name="jdbc/phonebookdb" password="" type="javax.sql.DataSource" url="jdbc:mysql://localhost:3306/phonebookdb?useUnicode=true&characterEncoding=UTF-8" username="root"/>
<Resource auth="Container" driverClassName="com.mysql.jdbc.Driver" maxActive="100" maxIdle="30" maxWait="10000" name="jdbc/phonebookdb2" password="" type="javax.sql.DataSource" url="jdbc:mysql://localhost:3306/phonebookdb2?useUnicode=true&characterEncoding=UTF-8" username="root"/>
<Realm className="org.apache.catalina.realm.DataSourceRealm" dataSourceName="jdbc/phonebookdb" debug="99" digest="md5" roleNameCol="ROLA" userCredCol="LOZINKA" userNameCol="EMAIL" userRoleTable="phonebook.ROLE" userTable="phonebookdb.KORISNICI"/>
<Realm className="org.apache.catalina.realm.DataSourceRealm" dataSourceName="jdbc/phonebookdb2" debug="99" digest="md5" roleNameCol="ROLA" userCredCol="LOZINKA" userNameCol="EMAIL" userRoleTable="phonebook2.ROLE" userTable="phonebookdb2.KORISNICI"/>
我实际上已经使它工作了，但与数据库通信的东西是不对的。当我尝试插入新用户（cro.korisnik）时，我得到了这个例外：
SEVERE: Cannot add or update a child row: a foreign key constraint fails (`phonebookdb`.`role`, CONSTRAINT `role_ibfk_5` FOREIGN KEY (`ROLA_ID`) REFERENCES `korisnici` (`KORISNIK_ID`) ON DELETE CASCADE ON UPDATE CASCADE)

答案 0 :(得分：0)
找到答案..我没有在映射到数据库表的持久化类中指定映射。 @Table（name =“phonebookdb.KORISNICI”） @Table（name =“phonebookdb2.KORISNICI”） 代替 @Table（name =“KORISNICI”） @Table（name =“KORISNICI”）
