Spring Boot WebFlux 应用程序重新启动并导致重复的 EnhancerBySpringCGLIB 错误。

Spring boot webflux app restarts and causes duplicate EnhancerBySpringCGLIB

问题

我有一个`Webflux`应用,在使用几分钟后会自动重新启动,`有时我可以使用几个小时`然后突然重新启动,当它重新启动时会弹出一个错误,显示重复的`EnhancerBySpringCGLIB`。我知道这个问题以前已经被提过,并且我尝试了建议的解决方案,但都没有奏效。下面是我的日志:

这是我的`CountryServiceImpl`的样子:

@Service
@Qualifier("CountryServiceImpl")
public class CountryServiceImpl extends BaseService<Country, CountryDto, CountryRepository> implements ICountryService {

	@Lazy
	@Autowired
	private CountryRepository countryRepository;

	@Lazy
	@Autowired
	private IJWTUtil jwtUtil;

	@Override
	public CountryRepository getRepository() {
		return countryRepository;
	}

	@Override
	public Mono<Country> createModel(CountryDto countryDto, Map<String, Claim> claims) {
		Country country = getModelMapper().map(countryDto, Country.class);
		country.setStatus(BaseModel.Status.ENABLED);
		return Mono.just(country);
	}

	@Override
	public Mono<Country> createUpdateModel(CountryDto countryDto, Map<String, Claim> claims) {
		return getRepository().findById(countryDto.getId())

						.name(countryDto.getName())
						.build()));
	}

	@Override
	public IJWTUtil getJwtUtil() {
		return jwtUtil;
	}
}

我的`ICountryService`接口:

public interface ICountryService extends IBaseService<Country, CountryDto> {
}

我的`BaseService`实现:

@Transactional
public abstract class BaseService<T extends BaseModel, V extends BaseDto, E extends BaseRepository<T>> implements IBaseService<T

I have a `Webflux` app that restarts automatically after a few minutes of usage, `sometimes I can use it for a couple of hours` then suddenly it restarts, when it restarts an error pops up saying duplicate `EnhancerBySpringCGLIB`. I know this question has been asked before and I tried the suggested solutions but none worked. below is my log

My `ICountryService` interface


	public interface ICountryService extends IBaseService&lt;Country, CountryDto&gt; {
	}


My `BaseService` Impl

	@Transactional
	public abstract class BaseService&lt;T extends BaseModel, V extends BaseDto, E extends BaseRepository&lt;T&gt;&gt; implements IBaseService&lt;T, V&gt; {

		@Getter
		private final ModelMapper modelMapper;

		abstract public E getRepository();

		public abstract Mono&lt;T&gt; createModel(V v, Map&lt;String, Claim&gt; claims);

		public abstract Mono&lt;T&gt; createUpdateModel(V v, Map&lt;String, Claim&gt; claims);

		public abstract IJWTUtil getJwtUtil();

		public Mono&lt;T&gt; validate(Mono&lt;T&gt; t) {
			return t;
		}

		public Flux&lt;T&gt; validate(Flux&lt;T&gt; t) {
			return t;
		}



		public BaseService() {
			modelMapper = new ModelMapper();
		}

		@Override
		public Mono&lt;ResponseEntity&lt;?&gt;&gt; create(V v, Optional&lt;String&gt; authorizationHeader) {
			Map&lt;String, Claim&gt; claims = authorizationHeader.map(mAuthorizationHeader -&gt; getJwtUtil().getAllClaims(mAuthorizationHeader)).orElse(new HashMap&lt;&gt;());
			Mono&lt;T&gt; model = this.createModel(v, claims);
			return create(model, claims)
					.flatMap(__ -&gt; Mono.&lt;ResponseEntity&lt;?&gt;&gt;just(ResponseEntity
							.status(HttpStatus.CREATED)
							.body(Response.builder()
									.payLoad(HttpStatus.CREATED)
									.build())))
					.switchIfEmpty(Mono.defer(() -&gt;
							Mono.just(ResponseEntity.status(HttpStatus.INTERNAL_SERVER_ERROR)
									.body(Response.builder()
											.status(HttpStatus.INTERNAL_SERVER_ERROR)
											.message(&quot;Unknown error occurred, try again&quot;)
											.build()))));
		}

		@Override
		public Mono&lt;T&gt; create(Mono&lt;T&gt; t, Map&lt;String, Claim&gt; claims) {
			return validate(t)
					.flatMap(k -&gt; getRepository().save(k));
		}


		@Override
		public Flux&lt;T&gt; createAll(List&lt;T&gt; t, Map&lt;String, Claim&gt; claims) {
			return validate(Flux.fromIterable(t))
					.thenMany(getRepository().saveAll(t));
		}
	}


And finally My `IBaseService` Interface

	public interface IBaseService&lt;T extends BaseModel, V extends BaseDto&gt; {

		Mono&lt;ResponseEntity&lt;?&gt;&gt; create(V v, Optional&lt;String&gt; authorizationHeader);

		Mono&lt;T&gt; create(Mono&lt;T&gt; t, Map&lt;String, Claim&gt; claims);

		Flux&lt;T&gt; createAll(List&lt;T&gt; t, Map&lt;String, Claim&gt; claims);
	}

After doing some reading I found out that `CGLIB` issues are usually caused by the `@Transactional` annotation as it generates proxies, a way around is to put it `@Transactional` on the parent of which I have but the error still pops up after the app restarts.

好的,以下是翻译好的部分:

好的,我找到了问题的根源,原来是`Java 9`的`module-info.java`文件,我在使用`RabbitMq`时遇到了问题,所有文件都被正确地导入了,但是它指出错误是来自我的`module-info.java`文件,所以我将它移除后,这个问题就没有再出现(RabbitMq也正常工作了)。据我理解,有一些内部类没有被放入允许访问列表中,这些类需要访问我的类,因此应用程序一直在失败。自那时以来,该应用程序一直在正常运行,没有任何问题。

Ok, so I found the culprit, turns out it was the `Java 9` `module-info.java`, I encountered an issue making `RabbitMq` work, all files were imported correctly but it was pointing to say the error was coming from my `module-info.java` so I removed it, after removing it I have not had this problem (and RabbitMq worked too), from my understanding, their are internal classes that were not put on the allow list that need to access my classes and because of that the app kept failing, the app has been working since then without any problems.
