tomcat下如何配置多个数据源

Question

应该写在server.xml中
 <Resource name="UserDatabase" auth="Container"
              type="org.apache.catalina.UserDatabase"
              description="User database that can be updated and saved"
              factory="org.apache.catalina.users.MemoryUserDatabaseFactory"
              pathname="conf/tomcat-users.xml" />
    <Resource 
  name="jdbc/BJCMS"
  auth="Container"
      type="javax.sql.DataSource" 
  driverClassName="com.microsoft.sqlserver.jdbc.SQLServerDriver" 
      url="jdbc:sqlserver://192.168.1.198:31416;DatabaseName=BJ_JRJCMS"
  username="JRJCMS" 
      password="JRJCMS" 
  maxActive="4" 
  maxIdle="2" 
  maxWait="5000" />
    <Resource 
  name="jdbc/PUBCMS"
  auth="Container"
      type="javax.sql.DataSource" 
  driverClassName="com.microsoft.sqlserver.jdbc.SQLServerDriver" 
      url="jdbc:sqlserver://192.168.1.198:31416;DatabaseName=PUB_JRJCMS"
  username="JRJCMS" 
      password="JRJCMS" 
  maxActive="4"
