问题描述

我在本地系统上使用Rest Controller和Oracle创建了一个Spring Boot应用程序，通过其IDE运行良好，mvn构建很好，程序包也不错，但是如果我将其作为可执行jar运行，则会出现以下错误。我已经提供了所有spring.datasource的application.properties，但是在这里出现错误。

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.

我正在尝试Spring Boot并尝试将其作为可执行的jar运行。

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

推荐答案

oracle.jdbc.driver.OracleDriver ，因为ojdbc7.jar包含在 system 范围内，就像提供的 在可见度方面。它可以在Eclipse中使用，因为Eclipse不会在作用域中苦苦挣扎，而只是在运行时包含了所有内容。

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.

您需要对依赖项进行 compile 或运行时。我相信这不能通过文件依赖项来完成。

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

定义一个Maven存储库以指向您的jar位置：

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>

将库移动/重命名为 $ {project.basedir} / src / lib / com / oracle / ojdbc7-12.1.0.1.jar

然后正常包含它：

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



解决方案2-将库安装到您的.m2



使用以下命令将jar安装到您的.m2存储库中：

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>

我认为以下应能完成工作：

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

，然后声明一个正常的依赖项：

And then declare a normal dependency:

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