没有'org.springframework.boot.orm.jpa.EntityManagerFactoryBuilder'类型的限定bean

In Java project, I am using Sprig Boot 1.5.3.RELEASE. It is connecting with two databases i.e. MongoDB and Microsoft SQLServer. When I run it with spring-boot:run goal, it works fine. However, when I try to run it with package goal then below error is reported by test cases despite the fact that those test cases are not connecting to SQL Server database:

在Java项目中,我使用的是Sprig Boot 1.5.3.RELEASE。它连接两个数据库,即MongoDB和Microsoft SQLServer。当我用spring-boot运行它:运行目标时,它运行正常。但是,当我尝试使用包目标运行它时,测试用例会报告以下错误,尽管这些测试用例未连接到SQL Server数据库:

The spring-boot:run goal is defined by the Mojo included within the spring-boot-maven-plugin project. You can find it here. https://github.com/spring-projects/spring-boot/blob/8e3baf3130220a331d540cb07e1aca263b721b38/spring-boot-tools/spring-boot-maven-plugin/src/main/java/org/springframework/boot/maven/RunMojo.java.

spring-boot:run目标由spring-boot-maven-plugin项目中包含的Mojo定义。你可以在这里找到它。 https://github.com/spring-projects/spring-boot/blob/8e3baf3130220a331d540cb07e1aca263b721b38/spring-boot-tools/spring-boot-maven-plugin/src/main/java/org/springframework/boot/maven/RunMojo。 java的。

The requiresDependencyResolution scope is set to Test. This will include the dependencies from each phase on the classpath. Take a look at the specification here. https://maven.apache.org/developers/mojo-api-specification.html

requiresDependencyResolution范围设置为Test。这将包括类路径上每个阶段的依赖关系。看看这里的规范。 https://maven.apache.org/developers/mojo-api-specification.html

The package goal provided by Maven wouldn't include these additional dependencies on the classpath and I believe that is the cause of your issues.

Maven提供的包目标不会在类路径中包含这些额外的依赖项,我相信这是导致问题的原因。

Spring Boot provides a repackage goal which is what should be used for building out executable spring-boot applications.

Spring Boot提供了一个重新打包目标,它应该用于构建可执行的spring-boot应用程序。

However, to get more to the point. I think if you update your test to exclude an additional class it might fix your problem.

但是,要获得更多关键点。我认为如果您更新测试以排除其他类,它可能会解决您的问题。

@DataMongoTest(excludeAutoConfiguration = {EmbeddedMongoAutoConfiguration.class, HibernateJpaAutoConfiguration.class})

@DataMongoTest(excludeAutoConfiguration = {EmbeddedMongoAutoConfiguration.class,HibernateJpaAutoConfiguration.class})
