我正在尝试使用Spring Boot应用程序中的DataSource访问数据库。我的数据源的Jndi名称是java：jboss / datasources / Mypool。我正在将应用程序作为war文件部署在JBoss EAP服务器中。
在pom.xml中，我删除了Apache Tomcat AS，如下所示：
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
<exclusions>
<exclusion>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
</exclusion>
</exclusions>
</dependency>
我在application.yml中添加了以下几行：
spring:
datasource:
driver-class-name: oracle.jdbc.driver.OracleDriver
jndi-name: java:jboss/datasources/MyPool
但是当我尝试从DAO类访问数据库时，它抛出以下异常：

当我通过驱动程序管理器而不是数据源访问数据库时，即当我在application.yml中包含以下行时，相同的代码正在工作：
spring:
datasource:
driver-class-name: oracle.jdbc.driver.OracleDriver
url: testurl
username: test
password: test
因此，代码中没有问题。请帮忙。
