Java 带休息和休息的弹簧靴；JPA，建筑战

我正在尝试学习本教程：

我已经成功地创建了一个Rest控制器并通过eclipse运行它，并且我能够在浏览器中获得JSON响应。我使用了ApacheDerby嵌入式数据库

我现在想做的是在我单独的Tomcat实例（非嵌入式）上运行它，并对MySQL数据库进行JNDI查找

上面提到的教程没有提到JNDI，所以我看了一下，建议添加

spring.datasource.jndi-name=java:comp/env/jdbc/mydb

转到application.properties文件

我非常确定我已经正确地设置了Tomcat，因为我以前在另一个应用程序中使用过JNDI查找，但是尝试使用Maven构建WAR失败：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaAutoConfiguration': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private javax.sql.DataSource org.springframework.boot.autoconfigure.orm.jpa.JpaBaseConfiguration.dataSource; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dataSource' defined in class path resource [org/springframework/boot/autoconfigure/jdbc/JndiDataSourceAutoConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [javax.sql.DataSource]: Factory method 'dataSource' threw exception; nested exception is org.springframework.jdbc.datasource.lookup.DataSourceLookupFailureException: Failed to look up JNDI DataSource with name 'java:comp/env/jdbc/finance'; nested exception is javax.naming.NoInitialContextException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file:  java.naming.factory.initial

教程似乎不完整，或者我错过了什么？我不知道如何继续。

什么时候发生异常

NoInitialContextException

可由嵌入式Tomcat引发，因为在运行mvn Package时，它没有默认启用JNDI。何时发生异常

NoInitialContextException

可以由嵌入式Tomcat抛出，因为在运行mvn包时，它没有默认启用JNDI
