如何在Spring Boot application.properties中配置Oracle RAC

Question

我正在使用Spring Boot 1.5.0.release，我想使用oracle RAC（快速連接故障轉移）和jdbc字符串將應用程序連接到oracle數據庫：

spring.datasource.url:jdbc:oracle:thin:jdbc:oracle:thin:@(DESCRIPTION=(ENABLE=BROKEN)(LOAD_BALANCE=ON)(FAILOVER=ON)(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=rac1-vip-ent.mncplaymedia.com)(PORT=1521))(ADDRESS=(PROTOCOL=TCP)(HOST=rac2-vip-ent.mncplaymedia.com)(PORT=1521))(ADDRESS=(PROTOCOL=TCP)(HOST=rac3-vip-ent.mncplaymedia.com)(PORT=1521))(ADDRESS=(PROTOCOL=TCP)(HOST=rac4-vip-ent.mncplaymedia.com)(PORT=1521))(ADDRESS=(PROTOCOL=TCP)(HOST=rac5-vip-ent.mncplaymedia.com)(PORT=1521)))(CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=ent)(FAILOVER_MODE=(TYPE=SELECT)(METHOD=BASIC)(RETRIES = 180)(DELAY = 5))))

spring.datasource.username:xxxx
spring.datasource.password:xxx
spring.datasource.driver-class-name:oracle.jdbc.driver.OracleDriver

而且我得到錯誤數據源返回null像這樣：

Caused by: java.sql.SQLTransientConnectionException: DataSource returned null unexpectedly
at com.zaxxer.hikari.pool.PoolBase.newConnection(PoolBase.java:343) ~[HikariCP-2.5.1.jar:na]
at com.zaxxer.hikari.pool.HikariPool.checkFailFast(HikariPool.java:506) ~[HikariCP-2.5.1.jar:na]
... 71 common frames omitted

任何人之前都會遇到此問題，請幫助我解決此問題。 對不起，我的英語不好。

您可以通過Spring博客查看UCP嗎？
