Springboot，tomcat 8，找不到Postgres的驱动程序

Question

I am using a spring boot applicaiton with Postgres.

But i can't get it running without adding my postgres.jar to the lib in the tomcat.

Are there any possibility to just use the postgres jar that i added within my application.

Realy want to issolate all my jar dependencies to my war and not change my Tomcat.

What i understand is it uses the the tomcat pooling for my application, are there any way to disable this?

This is my pom

Answer 1

You just need to add the postgres.jar as a dependency in your pom.xml.

<dependency>
    <groupId>org.postgresql</groupId>
    <artifactId>postgresql</artifactId>
</dependency>
