Spring Boot Factory method 'dataSource' threw exception with message: Failed to determine a suitable driver class

问题

我正在尝试构建一个使用Maven的Spring Boot项目的JAR文件。我正在使用IntelliJ IDE,并且当我在IntelliJ上运行项目时,它可以正常运行。

问题出现在我创建一个.JAR文件并尝试运行应用程序时,我遇到了以下错误:

01:10:49.889 [main] ERROR org.springframework.boot.SpringApplication -- Application run failed
org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaConfiguration': Unsatisfied dependency expressed through constructor parameter 0: Error creating bean with name 'dataSource' defined in class path resource [org/springframework/boot/autoconfigure/jdbc/DataSourceConfiguration$Hikari.class]: Failed to instantiate [com.zaxxer.hikari.HikariDataSource]: Factory method 'dataSource' threw exception with message: Failed to determine a suitable driver class

        ...

应用程序连接到MySQL数据库。以下是我的属性文件:

spring.datasource.url = jdbc:mysql://localhost:3306/ss_package_service
spring.datasource.username = root
spring.datasource.password = password
spring.datasource.driver-class-name = com.mysql.cj.jdbc.Driver

spring.jpa.generate-ddl = true
spring.jpa.hibernate.ddl-auto = update
spring.jpa.show-sql = true

这是我的POM文件:

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

        ...
    </dependencies>
    <build>

            </plugin>
        </plugins>
    </build>
</project>

我尝试删除了.m2文件夹并运行了mvn cleanmvn install,但没有成功。

欢迎提出建议。

I am trying to build a jar file of a spring boot project that uses maven. I am using Intellij IDE, and when I run the project on Intellij, it runs without issues.
The issue is when I create a .jar file and try to run the application I get the following error

The application connects to mysql database.
The following is my properties file

spring.datasource.url = jdbc:mysql://localhost:3306/ss_package_service
spring.datasource.username = root
spring.datasource.password = password
spring.datasource.driver-class-name = com.mysql.cj.jdbc.Driver


spring.jpa.generate-ddl = true
spring.jpa.hibernate.ddl-auto = update
spring.jpa.show-sql = true

and here is the pom file

&lt;?xml version=&quot;1.0&quot; encoding=&quot;UTF-8&quot;?&gt;

			&lt;scope&gt;test&lt;/scope&gt;
		&lt;/dependency&gt;
		&lt;dependency&gt;
			&lt;groupId&gt;com.fasterxml.jackson.core&lt;/groupId&gt;
			&lt;artifactId&gt;jackson-core&lt;/artifactId&gt;
			&lt;version&gt;2.15.1&lt;/version&gt;
		&lt;/dependency&gt;
	&lt;/dependencies&gt;

	&lt;build&gt;
		&lt;plugins&gt;
			&lt;plugin&gt;
				&lt;groupId&gt;org.springframework.boot&lt;/groupId&gt;
				&lt;artifactId&gt;spring-boot-maven-plugin&lt;/artifactId&gt;
			&lt;/plugin&gt;
		&lt;/plugins&gt;
	&lt;/build&gt;

&lt;/project&gt;

I tried removing the .m2 folder and run maven clean and maven install and no luck

Any suggestion will be appreciated.

你在pom.xml中有一个小拼写错误。这是正确的版本:

<dependency>
    <groupId>com.mysql</groupId>
    <artifactId>mysql-connector-j</artifactId>
    <version>8.0.33</version>
</dependency>
英文:

You have a small typo in pom.xml. This is the correct one:

&lt;dependency&gt;
    &lt;groupId&gt;com.mysql&lt;/groupId&gt;
    &lt;artifactId&gt;mysql-connector-j&lt;/artifactId&gt;
    &lt;version&gt;8.0.33&lt;/version&gt;
&lt;/dependency&gt;

所以,在进行了大量研究和头疼之后,我意识到在使用Intellij IDE创建jar文件时,application.properties没有被读取。

在测试不同方法时发生了这个错误以及其他错误,因为我通过Intellij生成了jar文件(Build -> Build Artifacts.)而不是使用maven。

为了解决这个问题,我改用了maven deploy,它生成了带有所有所需依赖项的正确的jar文件。

我希望这能帮到遇到同样问题的人。

英文:

So, after a lot of research and hair pulling I realized the application.properties is not being read when using Intellij IDE to create the jar file.

This error occurred and other errors as I was testing different approaches, because I generated the jar through Intellij (Build -> Build Artifacts. ) instead of using maven.

To resolve this I used maven deploy instead which generated the correct jar file with all required dependencies.

I hope this will help someone with the same issue.
