我有2個應用程序和2個數據庫。他們幾乎是一樣的。它實際上是2個電話簿。一個被命名爲phonebook other phonebook2。還有2個數據庫，phonebookdb和phonebookdb2。我使用Spring和Hibernate。我可以配置什麼，所以這可以工作。 我在context.xml中做到了這一點：Tomcat部署2個應用程序與2個數據庫
<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" />
在server.xml中我已經做到了這一點：
<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"/>
我已做了它的工作，但一些與交際與DATABSE是不對的。當我嘗試將新用戶（CRO korisnik）我得到這個異常：
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)
