Strange UnsatisfiedDependencyExceptions with spring boot tests
问题
org.springframework.beans.factory.UnsatisfiedDependencyException: 创建名为 'mycompany.service.DerpProcessorTest' 的 bean 时发生错误: 对字段 'derp' 表达的未满足的依赖项; 嵌套异常是 org.springframework.beans.factory.NoSuchBeanDefinitionException: 没有类型为 'mycompany.service.DerpProcessor' 的符合条件的 bean: 预期至少有 1 个 bean 符合自动装配候选项的要求。依赖注释: {@org.springframework.beans.factory.annotation.Autowired(required=true)}
英文:
So, I'm trying to inject a dependency to my test class with @Autowired, but I am getting weird errors with certain dependencies.
I've tried to isolate the issue and this is the simplest example:
package mycompany.service;
import lombok.extern.slf4j.Slf4j;
import org.springframework.stereotype.Service;
@Service
public class GenericDataProcessor {
}
package mycompany.service;
import com.fasterxml.jackson.databind.ObjectMapper;
import mycompany.config.ServiceTestConfiguration;
import mycompany.query.CachedQueryService;
import mycompany.sink.ProcessedDataSink;
import org.junit.jupiter.api.Test;
import org.junit.runner.RunWith;
import org.mockito.junit.MockitoJUnitRunner;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.boot.test.mock.mockito.MockBean;
import org.springframework.test.context.ActiveProfiles;
import org.springframework.test.context.ContextConfiguration;
@RunWith(MockitoJUnitRunner.class)
@ActiveProfiles("test")
@SpringBootTest(classes = {ServiceTestConfiguration.class})
@ContextConfiguration(classes = {ObjectMapper.class})
class GenericDataProcessorTest {
@Autowired
GenericDataProcessor genericDataProcessor;
@Autowired
ObjectMapper objectMapper;
@MockBean
ProcessedDataSink processedDataSink;
@MockBean
CachedQueryService cachedQueryService;
@Test
void test() {
}
}
This works just fine. But now when I just copypaste this (all to the same packages) as DerpProcessor and DerpProcessorTest like this:
package mycompany.service;
import org.springframework.stereotype.Service;
@Service
public class DerpProcessor {
}
package mycompany.service;
import com.fasterxml.jackson.databind.ObjectMapper;
import mycompany.config.ServiceTestConfiguration;
import mycompany.query.CachedQueryService;
import mycompany.sink.ProcessedDataSink;
import org.junit.jupiter.api.Test;
import org.junit.runner.RunWith;
import org.mockito.junit.MockitoJUnitRunner;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.boot.test.mock.mockito.MockBean;
import org.springframework.test.context.ActiveProfiles;
import org.springframework.test.context.ContextConfiguration;
@RunWith(MockitoJUnitRunner.class)
@ActiveProfiles("test")
@SpringBootTest(classes = {ServiceTestConfiguration.class})
@ContextConfiguration(classes = {ObjectMapper.class})
class DerpProcessorTest {
@Autowired
DerpProcessor derp;
@Autowired
ObjectMapper objectMapper;
@MockBean
ProcessedDataSink processedDataSink;
@MockBean
CachedQueryService cachedQueryService;
@Test
void test() {
}
}
I get the following error:
org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'mycompany.service.DerpProcessorTest': Unsatisfied dependency expressed through field 'derp'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'fi.cinia.dataconsumerservice.service.DerpProcessor' available: expected at least 1 bean which qualifies as autowire candidate.

I get the same error both when running it with IntelliJ & mvn command line. I also checked the target folder and it's building the DerpProcessor DerpProcessorTest classes correctly. There are also no weird configurations that would either filter DerpProcessor out or only include GenericDataProcessor
Really starting to run out of ideas & considering a career as a hermit fisherman.

唉，天哪，刚发完我注意到我有以下代码：
@Bean
@Primary
public GenericDataProcessor genericDataProcessor() {
return new GenericDataProcessor();
}
但是没有以下代码：
@Bean
@Primary
public DerpProcessor derpProcessor() {
return new DerpProcessor();
}
谢谢，橡皮鸭们！
英文:
Argh, JFC, just after posting this I noticed that I have
@Bean
@Primary
public GenericDataProcessor genericDataProcessor() {
return new GenericDataProcessor();
}
But no
@Bean
@Primary
public DerpProcessor derpProcessor() {
return new DerpProcessor();
}
Thanks, rubberducks!
