Question

我有一个新的Spring Boot（1.2.1.RELEASE）web / Jpa应用程序，我想连接到JNDI数据源（在独立的Tomcat的context.xml中定义的Oracle数据库）。

但是当我尝试这个时，我总是得到以下异常;

Unable to register MBean [org.apache.tomcat.dbcp.dbcp2.BasicDataSource@102f8ea9] with key 'dataSource'; nested exception is javax.management.InstanceAlreadyExistsException: Catalina:type=DataSource,class=javax.sql.DataSource,name="jdbc/npacore"

我的pom.xml看起来像这样：

JNDI配置在appliation.properties中看起来像这样：

spring.datasource.jndi-name=java:/comp/env/jdbc/npacore
spring.datasource.driverClassName=oracle.jdbc.driver.OracleDriver
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.Oracle10gDialect

我在这里关注MySQL的非常相似的博客：Spring Boot with JNDI Datasource

Answer 1

你在Spring Boot中点击了this issue。您可以通过将spring.jmx.enabled设置为false来解决此问题。

使用带有JNDI Oracle数据源的独立Tomcat进行Spring Boot
