问题


I created a spring boot application with Rest Controller and Oracle on my local system, thru IDE its running fine, the mvn build was fine package was also good but if I run it as executable jar I am getting the below error. I have application.properties in which I have provided all spring.datasource, but here I am getting error. Please advise.

I am trying out Spring boot and trying to run it as a excutable jar.


回答1:


oracle.jdbc.driver.OracleDriver isn't found at runtime, because ojdbc7.jar is included with the system scope, which is just like provided in terms of visibility. It works in Eclipse because Eclipse doesn't botter with the scopes and just includes everything at runtime.

You need the dependency to be either compile or runtime at least. I believe it cannot be done with a file dependency.

Solution 1 - Define a local repository

Define a maven repository to point to your jar location:

<repositories>
  <repository>
    <id>project-local-repo</id>
    <url>file://${project.basedir}/src/lib/</url>
  </repository>
</repositories>

Move/rename your library to ${project.basedir}/src/lib/com/oracle/ojdbc7-12.1.0.1.jar

And then include it normally:

<dependency>
    <groupId>com.oracle</groupId>
    <artifactId>ojdbc7</artifactId>
    <version>12.1.0.1</version>
</dependency>

Solution 2 - install the library into your .m2

Use the following command to install jar into your .m2 repository:

mvn install:install-file -Dfile=<jarfilePath> \
    -DgroupId=<groupId> \
    -DartifactId=<artifactId> \
    -Dversion=<version> \
    -Dpackaging=<packaging> \
    -DlocalRepositoryPath=<repoPath>

I think the following should do the job:

mvn install:install-file -Dfile=..../src/lib/ojdbc7.jar \
    -DgroupId=com.oracle \
    -DartifactId=ojdbc7 \
    -Dversion=12.1.0.1 \
    -Dpackaging=jar

And then declare a normal dependency:

<dependency>
    <groupId>com.oracle</groupId>
    <artifactId>ojdbc7</artifactId>
    <version>12.1.0.1</version>
</dependency>
