Autowired bean is null in CGLib proxy

I use CGlib proxy for intercept methods in controller and add some behavior for this.
But I've faced with problem when controller has autowired beans it didn't init and returned as null
#RestController
#RequestMapping("/test")
public class TestController {
#Autowired
private TestService service;
#PostMapping(
path = "/annotatedEndpoint",
consumes = MediaType.APPLICATION_JSON_UTF8_VALUE,
produces = MediaType.APPLICATION_JSON_UTF8_VALUE)
#SessionInfo
public ResponseEntity checkAnnotation(#RequestBody RequestDto request) {
SessionResponse response = request.getSessionInfo();
String test = service.getTestResult();
return ResponseEntity.ok(response);
}
}
In debugger I see that bean' class has inited TestService, but proxy didn't and tests fail with NullPointerException
org.springframework.web.util.NestedServletException: Request processing failed; nested exception is java.lang.NullPointerException

As I understand proxy is a "subclass" for a target class and I though that it just intercepts methods but uses superclass fields
Could I use superclass inited field, or autowire bean correctly in proxy?
TestService is a just dummy check-component
import org.springframework.stereotype.Service;
#Service
public class TestService implements TestServiceInterface {
public String getTestResult() {
return "check service";
}
}
Proxy building as
Enhancer enhancer = new Enhancer();
enhancer.setSuperclass(beanClass);
enhancer.setCallback(new SessionMethodInterceptor(sessionService));
return enhancer.create();

Looks like I've figured out how it can be resolved
I should pass original bean to interceptor
public Object postProcessAfterInitialization(Object bean, String beanName) throws BeansException {
if (classesWithAnnotatedMethods.get(beanName) != null) {
Enhancer enhancer = new Enhancer();
enhancer.setSuperclass(bean.getClass());
enhancer.setCallback(new SessionMethodInterceptor(bean));
return enhancer.create();
}
return bean;
}
And in the interceptor:
#RequiredArgsConstructor
public class SessionMethodInterceptor implements MethodInterceptor {
private final Object originalBean;
#Override
public Object intercept(Object obj, Method method, Object[] args, MethodProxy proxy) throws Throwable {
// * args' changes *
return method.invoke(originalBean, args);
}

GeoTools org.geotools.data.DataSourceException: dataType out of range

I'm trying to decode a Base64 encryption of a GeoTiff file, and after that get a GeoTiffReader using that file for later use. When I try this I keep getting this exception. I am new to GeoTools so there might be something obvious that I am missing here. Anny suggestions on how I can work around this issue?
Code:
public GeoLongLatGenerator(String base64) {
this.base64GeoTiff = base64.split(",")[1];
//Decode Base64 of GeoFile
try {
byte[] decodedStr = Base64.getDecoder().decode(base64GeoTiff);
String geoTiffString = new String(decodedStr, StandardCharsets.UTF_8);
try {
File GeoTiffFile = new File("geoTiff.tiff");
FileUtils.writeStringToFile(GeoTiffFile, geoTiffString, StandardCharsets.UTF_8);
AbstractGridFormat format = new GeoTiffFormat();
Hints hints = null;
if (format instanceof GeoTiffFormat) {
hints = new Hints(Hints.FORCE_LONGITUDE_FIRST_AXIS_ORDER,Boolean.TRUE);
GeoTiffReader reader = (GeoTiffReader) format.getReader(GeoTiffFile, hints);
GridCoverage2D cov = reader.read(null);
Envelope2D bbox = cov.getEnvelope2D();
printBBOX(bbox);
}else {
System.out.println("Format is not geoTiff: " + format.toString());
}
The Exception:

Subscribing to MailChimp list: Content Type '' not supported

I am trying to subscribe via Java SpringBoot, but I am facing a problem which I have a hard time to figure out why it's doing this.
public class MailChimpLogic implements ISubscribeLogic {
private final WebClient.Builder builder = WebClient.builder();
public ResponseEntity subscribe(MailChimpModelRequest request) {
String baseUri = "https://us7.api.mailchimp.com/3.0/lists/***";
String username = "***";
String token = "****-us7";
MailChimpResponse userSubscribed = builder.build()
.post()
.uri(baseUri)
.header("Authorization", "Basic " + Base64Utils
.encodeToString((username + ":" + token).getBytes(UTF_8)))
.body(BodyInserters.fromObject(request))
.retrieve()
.bodyToMono(MailChimpResponse.class)
.doOnError( e -> {
e.printStackTrace();
System.out.println("something happend" + e);
})
.block();
return new ResponseEntity(userSubscribed, HttpStatus.OK);
}
}
I tried to add
.contentType(MediaType.APPLICATION_JSON)
.accept( MediaType.ALL ) // I tried to use this one by one
And I even tried to use APPLICATION_JSON_UTF8 as content type but no success.
Here is the stacktrace:

I had 2 main problems which I identified with the help of fellow SO memeber #Trein.
The first problem is that my request was empty, this was because the models was missing a getter, setter and constructor.
Next I used
.contentType(MediaType.APPLICATION_JSON)
.syncBody(request)
This was making sure that the application type was set and the body was synced automaticly.
And for the last part I checked my request and it misnamed the json property's. Spring Boot expects Camel Cased Json name's, to change this I used the annotation #JsonProperty("New-Value")
And everything was working as a charm!

java.lang.IllegalArgumentException: Can't create an instance of class

My requirement is do password validation using JNA and I have wrote sample codes for this.
I have a java class as below,
public enum _NET_VALIDATE_PASSWORD_TYPE implements NativeMapped {
NetValidateAuthentication,
NetValidatePasswordChange,
NetValidatePasswordReset;
#Override
public Object fromNative(Object nativeValue, FromNativeContext context) {
return values()[(Integer) nativeValue];
//return ordinal();
}
#Override
public Object toNative() {
//return values();
return ordinal();
}
#Override
public Class<?> nativeType() {
return Integer.class;
}
}
calling the above enum method in below interface method,
public int NetValidatePasswordPolicy(String servername, String qualifier, _NET_VALIDATE_PASSWORD_TYPE validationType, LMAccess.NET_VALIDATE_PASSWORD_CHANGE_INPUT_ARG password, PointerByReference bufptr);
I have called the method from my service class,
_NET_VALIDATE_PASSWORD_TYPE enumvalue = _NET_VALIDATE_PASSWORD_TYPE.valueOf(_NET_VALIDATE_PASSWORD_TYPE.class,"NetValidatePasswordChange");
Netapi32Extn.INSTANCE.NetValidatePasswordPolicy(null, null, enumvalue, input,bufptr);
while execute I'm getting the below error,
2018-10-07 17:37:06.821 ERROR 31616 --- [nio-7777-exec-2] com.merckgroup.biop.utils.LogFactory : UserManagementController-Can't create an instance of class com.merckgroup.biop.win32.Netapi32Extn$_NET_VALIDATE_PASSWORD_TYPE, requires a no-arg constructor: java.lang.InstantiationException: com.merckgroup.biop.win32.Netapi32Extn$_NET_VALIDATE_PASSWORD_TYPE

Could some one please help me to resolve this issue?

The NativeMapped docs states
Implementations of this interface must provide a no-args constructor.
public enum _NET_VALIDATE_PASSWORD_TYPE implements NativeMapped {
NetValidateAuthentication,
NetValidatePasswordChange,
NetValidatePasswordReset;
private _NET_VALIDATE_PASSWORD_TYPE() { }
#Override
public Object fromNative(Object nativeValue, FromNativeContext context) {
return values()[(Integer) nativeValue];
//return ordinal();
}
#Override
public Object toNative() {
//return values();
return ordinal();
}
#Override
public Class<?> nativeType() {
return Integer.class;
}
}

Could not perform RPC via Ribbon(and Eureka)

I am trying to write helloworld application using micro servise technique. In more details - I use spring cloud.
My hello world application interacts like this:
hello_service has single rest method:
#GetMapping("/hello")
public String hello(#RequestParam("name") String name) {
return "Hello " + name + "!";
}
hello_world_service uses hello_service and pass world as parameter
For routing I try to use ribbon+eurika. But I get following error:
I get following error:

Please help me to fix this issue.
P.S.
Full source code can be found here: https://github.com/gredwhite/spring-cloud

I found out that issue was related with service name hello_service.
In result of the URI parsing hello_service was a credentials. I fixed issue replacing hello_service with hello-service
