I want to programmatically enable Spring Boot Actuator metrics for Spring MVC (using Spring Boot 2.6.3).
I can put
management.metrics.web.server.request.autotime.enabled=true in the application.properties file to achieve this.
But I do not like .properties files for multiple reasons. I'd rather do it in code while defining my MeterRegistry bean.
Right now, my metrics configuration looks like this:
#Configuration
public class MetricsConfig {
#Value("${spring.profiles.active:default}")
private String activeProfile;
#Bean
public PrometheusMeterRegistry prometheusMeterRegistry() {
var config = new CustomPrometheusConfig(Duration.ofSeconds(10));
var registry = new PrometheusMeterRegistry(config);
registry.config()
.meterFilter(new AddPrefixMeterFilter("my."))
.meterFilter(new DistributionSummaryFilter())
.commonTags(
"instance", StringUtils.defaultString(System.getenv("HOSTNAME"), "no-hostname"),
"env", activeProfile)
.namingConvention(PrometheusNamingConvention.snakeCase);
new JvmMemoryMetrics().bindTo(registry);
new JvmThreadMetrics().bindTo(registry);
new JvmGcMetrics().bindTo(registry);
new JvmHeapPressureMetrics().bindTo(registry);
new LogbackMetrics().bindTo(registry);
return registry;
}
#Bean
public TimedAspect timedAspect(MeterRegistry registry) {
return new TimedAspect(registry);
}
public static class AddPrefixMeterFilter implements MeterFilter {
private final String prefix;
public AddPrefixMeterFilter(String prefix) {
this.prefix = prefix;
}
#NotNull
#Override
public Meter.Id map(Meter.Id id) {
return id.withName(prefix + id.getName());
}
}
public static class DistributionSummaryFilter implements MeterFilter {
#Override
public DistributionStatisticConfig configure(#NotNull Meter.Id id,
#NotNull DistributionStatisticConfig config) {
return DistributionStatisticConfig.builder()
.percentiles(0, 0.5, 0.95, 1)
.percentilesHistogram(true)
.build()
.merge(config);
}
}
public static class CustomPrometheusConfig implements PrometheusConfig {
private final Duration step;
private CustomPrometheusConfig(Duration step) {
this.step = step;
}
#NotNull
#Override
public Duration step() {
return step;
}
#NotNull

What I am trying to do? : I am new to Spring Integration and already have read many similar questions regarding error handling but I don't understand how to catch exceptions using error-channel?

Also currently, I am facing
required a bean of type org.springframework.messaging.support.ErrorMessage that could not be found
I need some assistance!
Thanking you in advance,
EDIT
#AllArgsConstructor
#Service
public class AsyncNonBlockingClient implements Connector {
TcpClientGateway tcpClientGateway;
#Override
public String send(final String payload) {
return tcpClientGateway.send(payload);
}
}
See documentation about messaging annotation:
Your problem is here: https://docs.spring.io/spring-integration/docs/current/reference/html/configuration.html#annotations_on_beans
#Bean
#ServiceActivator(inputChannel = "error-channel")
public void handleError(ErrorMessage em) {
This is a plain POJO method, therefore it cannot be marked with a #Bean. You use a #Bean really for beans to expose. Then you decide if that has to be a #ServiceActivator or not. So, just remove #Bean from this method and your error-channel consumer should be OK.
I am trying to use spring cache abstraction with Redis cache. I am unable to see the values in cache. Please help me if I am missing something in config :
As I am making the call multiple times actual fetch is happening. I tried connecting to same redis host port, I cant find there any keys as well.
PFB the implementation details.

I am trying to write and test an application that used spring-cloud with azure functions following this tutorial.
https://github.com/markusgulden/aws-tutorials/tree/master/spring-cloud-function/spring-cloud-function-azure/src/main/java/de/margul/awstutorials/springcloudfunction/azure
I am tryign to write a testcase and override the bean.
Here is the application class having function and handler Bean function.
#SpringBootApplication
#ComponentScan(basePackages = { "com.package" })
public class DataFunctions extends AzureSpringBootRequestHandler<GenericMessage<Optional<String>>, Data> {
#FunctionName("addData")
public HttpResponseMessage addDataRun(
#HttpTrigger(name = "add", methods = {
HttpMethod.POST }, authLevel = AuthorizationLevel.FUNCTION) HttpRequestMessage<Optional<String>> request,
final ExecutionContext context) throws JsonParseException, JsonMappingException, IOException {
context.getLogger().info("Java HTTP trigger processed a POST request.");
try {
handleRequest(new GenericMessage<Optional<String>>(request.getBody()), context);
} catch (ServiceException ex) {
ErrorMessage em = new ErrorMessage();
return request.createResponseBuilder(handleException(ex, em)).body(em).build();
}
return request.createResponseBuilder(HttpStatus.CREATED).build();
}
#Autowired
MyService mService;
#Bean
public Consumer<GenericMessage<Optional<String>>> addData() {
ObjectMapper mapper = new ObjectMapper();
return req -> {
SomeModel fp = null;
try {
fp = mapper.readValue(req.getPayload().get(), SomeModel.class);
} catch (Exception e) {
throw new ServiceException(e);
}
mService.addData(fp);
};
}
}
I want to test by overriding the above bean.
Cosmosdb spring configuration
#Configuration
#EnableDocumentDbRepositories
public class CosmosDBConfig extends AbstractDocumentDbConfiguration {
#Value("${cosmosdb.collection.endpoint}")
private String uri;
#Value("${cosmosdb.collection.key}")
private String key;
#Value("${cosmosdb.collection.dbname}")
private String dbName;
#Value("${cosmosdb.connect.directly}")
private Boolean connectDirectly;
#Override
public DocumentDBConfig getConfig() {
ConnectionPolicy cp = ConnectionPolicy.GetDefault();
if (connectDirectly) {
cp.setConnectionMode(ConnectionMode.DirectHttps);
} else {
cp.setConnectionMode(ConnectionMode.Gateway);
}
return DocumentDBConfig.builder(uri, key, dbName).connectionPolicy(cp).build();
}
}
Here is the configuration
#TestConfiguration
#PropertySource(value = "classpath:application.properties", encoding = "UTF-8")
#Profile("test")
#Import({DataFunctions.class})
public class TestConfig {
#Bean(name="addData")
#Primary
public Consumer<GenericMessage<Optional<String>>> addData() {
return req -> {
System.out.println("data mock");
};
}
#Bean
#Primary
public DocumentDBConfig getConfig() {
return Mockito.mock(DocumentDBConfig.class);
}
}
Finally the test class
#RunWith(SpringRunner.class)
//#SpringBootTest //Enabling this gives initialization error.
#ActiveProfiles("test")
public class TempTest {
#InjectMocks
DataFunctions func;
#Mock
MyService mService;
#Before
public void setup() {
MockitoAnnotations.initMocks(this);
}
private Optional<String> createRequestString(final String res) throws IOException {
InputStream iStream = TempTest.class.getResourceAsStream(res);
String charset="UTF-8";
try (BufferedReader br = new BufferedReader(new InputStreamReader(iStream, charset))) {
return Optional.of(br.lines().collect(Collectors.joining(System.lineSeparator())));
}
}
#Test
public void testHttpPostTriggerJava() throws Exception {
#SuppressWarnings("unchecked")
final HttpRequestMessage<Optional<String>> req = mock(HttpRequestMessage.class);
final Optional<String> queryBody = createRequestString("/test-data.json");
doNothing().when(mService).addData(Mockito.any(SomeModel.class));
doReturn(queryBody).when(req).getBody();
doAnswer(new Answer<HttpResponseMessage.Builder>() {
#Override
public HttpResponseMessage.Builder answer(InvocationOnMock invocation) {
HttpStatus status = (HttpStatus) invocation.getArguments()[0];
return new HttpResponseMessageMock.HttpResponseMessageBuilderMock().status(status);
}
}).when(req).createResponseBuilder(any(HttpStatus.class));
final ExecutionContext context = mock(ExecutionContext.class);
doReturn(Logger.getGlobal()).when(context).getLogger();
doReturn("addData").when(context).getFunctionName();
// Invoke
final HttpResponseMessage ret = func.addDataRun(req, context);
// Verify
assertEquals(ret.getStatus(), HttpStatus.CREATED);
}
}
For this case instead of test configuration addData the actual bean is called from DataFunctions class. Also the database connection is also created when it should use the mocked bean from my test configuration. Can somebody please point out what is wrong in my test configuration?
I was able to resolve the first part of cosmos db config loading by marking it with
#Configuration
#EnableDocumentDbRepositories
#Profile("!test")
public class CosmosDBConfig extends AbstractDocumentDbConfiguration {
...
}
Also had to mark the repository bean as optional in the service.
public class MyService {
#Autowired(required = false)
private MyRepository myRepo;
}
Didn't use any spring boot configuration other than this.
#ActiveProfiles("test")
public class FunctionTest {
...
}
For the second part of providing mock version of Mock handlers, I simply made the test config file as spring application as below.
#SpringBootApplication
#ComponentScan(basePackages = { "com.boeing.da.helix.utm.traffic" })
#Profile("test")
public class TestConfiguration {
public static void main(final String[] args) {
SpringApplication.run(TestConfiguration.class, args);
}
#Bean(name="addData")
#Primary
public Consumer<GenericMessage<Optional<String>>> addData() {
return req -> {
System.out.println("data mock");
};
}
}
and made use of this constructor from azure functions library in spring cloud in my constructor
public class AppFunctions
extends AzureSpringBootRequestHandler<GenericMessage<Optional<String>>, List<Data>> {
public AppFunctions(Class<?> configurationClass) {
super(configurationClass);
}
}
public AzureSpringBootRequestHandler(Class<?> configurationClass) {
super(configurationClass);
}
Hope it helps someone.
I have the following sftp camel component configuration:
#Configuration
public class FtpCamelComponent {
#Value("${SFTP_HOST}")
private String sftpHost;
#Value("${SFTP_KNOWNHOST}")
private String sftpKnownHost;
#Value("${SFTP_KEY}")
private String sftpKey;
#Value("${SFTP_USER}")
private String sftpUser;
#Value("{SFTP_DIRECTORY}")
private String sftpFileDirectory;
#Bean
public SftpConfiguration sftpConfiguration(){
SftpConfiguration sftpConfiguration = new SftpConfiguration();
sftpConfiguration.setUsername(sftpUser);
sftpConfiguration.setHost(sftpHost);
sftpConfiguration.setKnownHostsFile(sftpKnownHost);
sftpConfiguration.setPrivateKeyFile(sftpKey);
sftpConfiguration.setDirectory(sftpFileDirectory);
return sftpConfiguration;
}
#Bean
public SftpEndpoint sftpEndpoint(SftpConfiguration sftpConfiguration){
SftpEndpoint sftpEndpoint = new SftpEndpoint();
sftpEndpoint.setConfiguration(sftpConfiguration);
sftpEndpoint.setEndpointUriIfNotSpecified("sftp");
return sftpEndpoint;
}
#Bean
public SftpComponent sftpComponent(SftpEndpoint sftpEndpoint){
SftpComponent sftpComponent = new SftpComponent();
sftpComponent.setEndpointClass(sftpEndpoint.getClass());
return sftpComponent;
}
}
I added the component to my camel context:
#Configuration
#Import({FtpCamelComponent.class,
SftpCamelRoute.class})
public class SftpCamelContext extends CamelConfiguration {
#Autowired
SftpComponent sftpComponent;
#Bean(name = "sftpCamelContext")
protected CamelContext createCamelContext() throws Exception {
SpringCamelContext camelContext = new SpringCamelContext();
camelContext.setApplicationContext(getApplicationContext());
camelContext.addComponent("sftp", sftpComponent);
return camelContext;
}
}
Why can't I just use sftp: in my camel route as I have already configured it and added it to my camel context?
#Bean(name = "FileToSftp")
public RouteBuilder fileToSFTP(){
return new RouteBuilder() {
public void configure() {
from("direct:fileToSftp")
.to("file:export/b1?fileName=export.csv")
.setHeader("CamelFileName", constant("export.csv"))
.to("sftp://dev#localhost:/export/in/?knownHostsFile=key/knownhost&privateKeyFile=key/id_rsa.pub&localWorkDirectory=export/b1&download=false");
}
};
}
