无法部署Spring Boot Jar应用程序

Question

I'm developping a spring boot application and it works fine when I run the command:

mvn spring-boot:run

But when deploying jar file with the command:

java -jar target\\jarfile.jar

I get the following error:

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'employeeResource': Unsatisfied dependency expressed through field 'hrServicesSilo'; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'hrServicesSilo': Unsatisfied dependency expressed through field 'employeeService'; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'employeeService': Unsatisfied dependency expressed through field 'employeeRepository'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'employeeRepository': Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: Not a managed type: class com.intranet.si.model.hr.Employee

        at org.springframework.beans.factory.annotation.InjectionMetadata.inject(InjectionMetadata.java:88) ~[spring-beans-4.3.14.RELEASE.jar!/:4.3.14.RELEASE]

What am I doing wrong?

Answer 1

I can see a repository so I assume you use spring-data . It is strange that it works in maven and not working after packaging so you can try the following:

1. Check that you use spring-maven-plugin to package your application.
2. Try to add @EntityScan("com.intranet.si.model.hr") (can also be com.intranet.si.model to recursivly catch all models in the package and sub-packages) to one of your configuration classes or to the application class (the one annotated with @SpringBootApplication ). This will notify spring + hibernate where to scan for entities. Also make sure your entity is annotated with @Entity .
3. I guess that you already have @EnableJpaRespotories in one of your configuration files but make sure it is configured as well.
