SpringBootTest 在使用 Docker 构建 Jenkins 期间由于 UnsatisfiedDependencyException 而失败

Question

First of all, it might look duplicate to other post on stackoverflow, and I tried couple of solutions. But, none solving my issue.

Issue:

Springboot test getting failed due to UnsatisfiedDependencyException during jenkins build. But, interestingly, on local system I don't see same exception and I'm able to build same codebase without any error/exception.

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'myAppServiceImpl' defined in file [/use/jenkins/path to class/MyAppServiceImpl.class]: Unsatisfied dependency expressed through constructor parameter 1;

I'm getting this issue only during jenkins build whereas on my local system. I'm able to build the same codebase without any issue. So, I'm not sure what should I make change to make it work on platform.

Due to restriction, I won't be able to share exact code, but I'm sharing similar to it.

package com.tg.app.main.engine

@SpringBootApplication
@EnableConfigurationProperties(MyApplicationProperties.class)
@ComponentScan("com.tg.app")
class MyApplication{
// main method
}

Test

@RunWith(SpringRunner.class)
@SpringBootTest(webEnvironment=WebEnvironment.RANDOM_PORT, classes=MyApplication.class)
@AutoConfigurationMockMvc
@AutoConfigureWebTestClient(timeout="100000")
class MyApplicationTest{

 @Autowire
 private MyAppService myAppService;

//codes

}

Service

   package com.tg.app.main.engine.service
   public interface MyAppService{
   //method declaration
   }

   @Service
   public MyAppServiceImpl implements MyAppService{
   private UserService userService
   private String xyz;

      @Autowire
      public MyAppServiceImpl(String xyz, UserService userService){
       this.xyz=xyz;
       this.userService=userService;
      }
   }

I also tried adding MyAppService as below as suggested in some post.

@SpringBootTest(webEnvironment=WebEnvironment.RANDOM_PORT, classes={MyApplication.class, MyAppService.class})

Then, one of the post on stackoverflow ( Must use mockbean instead of autowired ) suggesting not to use @MockBean (Although, I tried it, which didn't helped in my case). So, I'm not sure what should I do to fix this issue. Need help. Since, this is only occurring on platform, so not possible to hit and trail there multiple times.

Please let me know, if any other information is required.

==Edit==

The same code was earlier working fine. This time we have upgraded the SpringBoot version from 2.0 to 2.1 and removed couple of unnecessary libraries. As mentioned above, code is just to give you an idea about the structure of code. They aren't actual code. Another thing to note here is, I'm able to successfully build same code on local machine and even bring up the service without any issue . So, I'm very sure, nothing wrong with the code. It's something to do with platform where this code is getting built.

I noted couple of differences between my local machine and platform. First, build triggered using Docker , which isn't the case when I'm doing in local (just executing maven command). And other one is, Integration Testing running using OpenJDK ( maven 3.3.9-jdk-8 ) on platform whereas on my local I'm using Java Hotspot (Oracle jdk-8) . Other than this, I didn't see any difference between local system and platform.

Thanks.

Answer 1

The problem is with your String xyz in MyAppServiceImpl , Spring isn't actually finding an autowire candidate, you could add to your test class:

@MockBean
private String xyz = "whatever you are trying to inject";

This way you will surpass your failed dependency injection

Answer 2

Looking at code that is not currently causing the issue is a wast of time.

If you can`t share the actual code due to confidentiality, then you should create a test project that gives you the same error and share here.

That been said, I advise you to check for any profiles in maven that are active in your machine, but is disabled in the jenkins environment, or vice versa.
