I'm upgrading spring-boot to 2.6.2 and spring-cloud to 2021.0.0, and after upgrading, the brave.Tracer was not able to autowired in a #Configuration class.
The Tracer is autowired as parameter with #Bean component.
I have tried solutions in this question but doesn't work.
here is the #Configuration class:
#Configuration
#ConditionalOnWebApplication
#AutoConfigureAfter(CommonsAutoConfig.class)
#EnableConfigurationProperties({CorsConfig.class, TracingConfiguration.class})
public class WebCommonsAutoConfig
{
......
#Bean(name = "httpRestRequestResponseLogger")
#RefreshScope
public FilterRegistrationBean httpRestRequestResponseLogger(
RequestResponseLogger requestResponseLogger,
HeaderAccessor headerAccessor,
Tracer tracer,
HeaderExtractor<HttpServletRequestLoggingWrapper> httpHeaderExtractor)
{
final HttpLogFilter httpLogFilter= new HttpLogFilter(requestResponseLogger,
headerAccessor, tracer, httpHeaderExtractor);
final FilterRegistrationBean registrationBean = new FilterRegistrationBean();
registrationBean.setFilter(httpLogFilter);
registrationBean.setDispatcherTypes(ASYNC, ERROR, FORWARD, INCLUDE, REQUEST);
registrationBean.setOrder(HttpLogFilter.ORDER);
return registrationBean;
}
....
}
With the following error log:
...
Caused by: org.springframework.beans.factory.UnsatisfiedDependencyException: Error
creating bean with name 'scopedTarget.httpRestRequestResponseLogger' defined in class
path resource [com/vzt/WebCommonsAutoConfig.class]: Unsatisfied dependency expressed

...
Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No
qualifying bean of type 'brave.Tracer' available: expected at least 1 bean which
qualifies as autowire candidate. Dependency annotations: {}
So what shall I do to make the brave.Tracer autowired in this #Configuration class?
Most likely you need to add #AutoConfigureAfter(BraveAutoConfiguration.class). I understand that spring cloud sleuth is on the classpath?

With a configuration class you could initialize your beans manually, specially if they need custom names.
#Configuration
public class MyCustomConfiguration {
#Bean(name ="headerProcessor")
public ItemProcessor<FileHeader, FileHeader> headerProcessorBean() {
ItemProcessor<FileHeader, FileHeader> myBean = new HeaderProcessor<>();
//Do whaterever you need to initilize your bean
return myBean;
}
#Bean(name ="detailProcessor")
public ItemProcessor<FileDetail, FileDetail> detailProcessorBean() {
ItemProcessor<FileDetail, FileDetail> myBean = new ItemProcessor<>();
//Do whaterever you need to initilize your bean
return myBean;
}
}
In this way these beans will be available for autowiring.
I'm using Spring Boot 2.2.4 and I'm trying to a custom Executor
Below are the relevant classes
#Configuration
#ManagedResource
public class ExecutorConfig {
#Bean(name = "detailsScraperExecutor")
public Executor getDetailsAsyncExecutor() {
ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor();
executor.setCorePoolSize(5);
executor.setQueueCapacity(1000000);
executor.setThreadNamePrefix("detailsScraperExecutor-");
executor.initialize();
return executor;
}
}
and the following class which tries to use it.
#Component
#Profile("!test")
public class DetailsScraper {
private static final Logger logger = LoggerFactory.getLogger(DetailsScraper.class);
#Autowired
#Qualifier("detailsScraperExecutor")
private ThreadPoolTaskExecutor detailsScraperExecutor;
}
When I run the application I get the following error
org.springframework.beans.factory.UnsatisfiedDependencyException:

Even though I have named it detailsScraperExecutor Spring can't find it? Why is that?
You need to inject the same type of class as declared in configuration but not a higher-level one. But you can use the lower-level one.
#Autowired
private Executor detailsScraperExecutor;
I am using spring retry (http://docs.spring.io/spring-retry/docs/1.1.2.RELEASE/apidocs/) in a maven project and I have the following unit test
#RunWith(SpringJUnit4ClassRunner.class)
#ContextConfiguration
public class RetriableFileManagerTest {
#Autowired
#Qualifier("asset")
private AssetResource assetResource;
#Test
public void testRetry() throws URISyntaxException {
byte[] image = this.assetResource.fetchResource("name", "path");
verify(assetResource, times(3)).fetchResource("name", "path");
Assert.assertEquals("should be equal", "image", new String(image));
}
#Configuration
#EnableRetry
public static class SpringConfig {
#Bean(name = "asset")
public AssetResource assetResource() throws Exception {
AssetResource remoteService = mock(AssetResource.class);
when(remoteService.fetchResource(anyString(), anyString()))
.thenThrow(new RuntimeException("Remote Exception 1"))
.thenThrow(new RuntimeException("Remote Exception 2"))
.thenReturn("Completed".getBytes());
return remoteService;
}
}
}
However when I try to run the test it fails with
Caused by: org.springframework.beans.factory.BeanCreationException: Could not autowire field: private ctp.cms.actions.handlers.repository.resources.AssetResource ctp.cms.actions.handlers.filemanager.RetriableFileManagerTest.assetResource; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [ctp.cms.actions.handlers.repository.resources.AssetResource] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

Finally figured out the issue, I had to move the #Retryable annotation to the interface that AssetResource implements and autowire this interface type to the unit test.
Error message says
No qualifying bean of type
[ctp.cms.actions.handlers.repository.resources.AssetResource] found
for dependency
How is ctp.cms.actions.handlers.repository.resources.AssetResource declared?
Do you have #Component (#Service or similar annotation on it?) Is this package enabled for #ComponentScan ?

And this is my code when I recive error:
#Autowired
public DummyController(ActuatorMetricsPrinter metricsPrinter) {
this.metricsPrinter = metricsPrinter;
}
I have a class ActuatorMetricsPrinter that show the metrics but I have a problem when try fill this repository
*EDIT *
#Component
public class ActuatorMetricsPrinter {
private MetricRepository repository;
private static final String TEMPLATE = "Metric: %s [%s]";
private Collection<PublicMetrics> publicMetrics = null;
public String printAllMetrics() {
StringBuilder sb = new StringBuilder();
for (PublicMetrics pm : publicMetrics) {
sb.append("Public Metric: " + pm.getClass().getName());
sb.append("\n\n");
for (Metric<?> m : pm.metrics()) {
sb.append(String.format(TEMPLATE, m.getName(), m.getValue().toString()));
sb.append("\n");
}
}
return sb.toString();
}
#Autowired
public void MetricExporterService(MetricRepository repository) {
this.repository = repository;
}
And
#Controller
public class DummyController {
private final ActuatorMetricsPrinter metricsPrinter;
#Autowired
public DummyController(ActuatorMetricsPrinter metricsPrinter) {
this.metricsPrinter = metricsPrinter;
}
#RequestMapping(value = "/customMetrics", method = RequestMethod.GET)
#ResponseBody
public String printMetrics() {
return metricsPrinter.printAllMetrics();
}
#Bean
public ActuatorMetricsPrinter publicMetrics() {
return new ActuatorMetricsPrinter();
}
}
Thank you very much!
Spring beans factory not found a bean Collection<PublicMetrics> publicMetrics for autowarid; try to create a list of PublicMetrics
see : Spring autowire a list
Auto-wiring a List using util schema gives NoSuchBeanDefinitionException
In your case the actual problem is initializing the constructor for ActuatorMetricsPrinter. You have it Autowired to take in a Collection so Spring is trying to find the set of PublicMetrics beans to use as a collection and it cannot find any. Here is the error in what you provided above that points to that. I ran into the same issue myself at one point.
No qualifying bean of type
[org.springframework.boot.actuate.endpoint.PublicMetrics] found for
dependency [collection of
org.springframework.boot.actuate.endpoint.PublicMetrics]: expected at
least 1 bean which qualifies as autowire candidate for this
dependency.
From the Spring Docs on Autowired:
In case of a Collection or Map dependency type, the container will
autowire all beans matching the declared value type. In case of a Map,
the keys must be declared as type String and will be resolved to the
corresponding bean names.
Since the PublicMetrics are not declared as beans I think the right way to do it is by autowiring to a MetricRepository. See this link and the Exporting Metrics section there as a reference. There is a link to a sample application. Here is some modified code that you can use.
#Autowired
public MetricExporterService(MetricRepository repository) {
this.repository = repository;
}
public String printAllMetrics() {
StringBuilder sb = new StringBuilder();
for (Metric metric : repository.findAll()) {
sb.append(String.format(TEMPLATE, metric.getName(), metric.getValue().toString()));
}
return sb.toString();
}
I am using Spring boot and Liquibase.
Using this url as guidelines
http://docs.spring.io/spring-boot/docs/current-SNAPSHOT/reference/htmlsingle/
In pom.xml, the below entry is present so that spring boot knows about liquibase.
<dependency>
<groupId>org.liquibase</groupId>
<artifactId>liquibase-core</artifactId>
</dependency>
and put the changelog file in resources folder.
db.changelog-master.xml
Now Spring boot first tring to find db.changelog-master.yaml in classpath and throwing the exception like this.
Cannot find changelog location: class path resource [db/changelog/db.changelog-master.yaml
To Fix the Issue, I have added the bean like below in my class and tried to set changeLog proprty.
#Configuration
#ComponentScan
#EnableAutoConfiguration
public class SampleDataJpaApplication {
#Autowired
LiquibaseProperties properties;
#Autowired
private DataSource dataSource;
#Bean
public SpringLiquibase liquibase() {
SpringLiquibase liquibase = new SpringLiquibase();
properties.setChangeLog("classpath:/db/changelog/db.changelog-master.xml");
liquibase.setChangeLog(this.properties.getChangeLog());
liquibase.setContexts(this.properties.getContexts());
liquibase.setDataSource(this.dataSource);
liquibase.setDefaultSchema(this.properties.getDefaultSchema());
liquibase.setDropFirst(this.properties.isDropFirst());
liquibase.setShouldRun(this.properties.isEnabled());
return liquibase;
}
public static void main(String[] args) throws Exception {
Logger logger = LoggerFactory.getLogger("SampleDataJpaApplication");
SpringApplication springApplication = new SpringApplication();
springApplication.run(SampleDataJpaApplication.class, args);
}
}
but it is failing with the message.

Please provide the inputs here, why i am getting this exception or Is there any any other available way to override the same class so that i can change the changeLog property of liquibase properties.
I'm not entirely sure what the exact runtime path to your change log is, but why don't you just use the "liquibase.*" properties in application.properties? You should be able to leave out the Liquibase #Bean and let Boot do it for you.
If you prefer to add you own Liquibase #Bean then take the hint and make sure you define a LiquibaseProperties bean as well (e.g. by declaring #EnableConfigurationProperties(LiquibaseProperties.class)).
