Spring 启动 webflux 应用程序重新启动并导致重复的 EnhancerBySpringCGLIB
Spring boot webflux app restarts and causes duplicate EnhancerBySpringCGLIB
我有一个 Webflux 应用程序，在使用几分钟后会自动重启，sometimes I can use it for a couple of hours 然后突然重启，当它重启时会弹出一个错误，提示重复 EnhancerBySpringCGLIB。我知道之前有人问过这个问题，我尝试了建议的解决方案，但 none 奏效了。下面是我的日志

这就是我的 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())
.flatMap(country -> Mono.just(country.toBuilder()
.name(countryDto.getName())
.build()));
}
@Override
public IJWTUtil getJwtUtil() {
return jwtUtil;
}
}
我的ICountryService界面
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, V> {
@Getter
private final ModelMapper modelMapper;
abstract public E getRepository();
public abstract Mono<T> createModel(V v, Map<String, Claim> claims);
public abstract Mono<T> createUpdateModel(V v, Map<String, Claim> claims);
public abstract IJWTUtil getJwtUtil();
public Mono<T> validate(Mono<T> t) {
return t;
}
public Flux<T> validate(Flux<T> t) {
return t;
}
public BaseService() {
modelMapper = new ModelMapper();
}
@Override
public Mono<ResponseEntity<?>> create(V v, Optional<String> authorizationHeader) {
Map<String, Claim> claims = authorizationHeader.map(mAuthorizationHeader -> getJwtUtil().getAllClaims(mAuthorizationHeader)).orElse(new HashMap<>());
Mono<T> model = this.createModel(v, claims);
return create(model, claims)
.flatMap(__ -> Mono.<ResponseEntity<?>>just(ResponseEntity
.status(HttpStatus.CREATED)
.body(Response.builder()
.payLoad(HttpStatus.CREATED)
.build())))
.switchIfEmpty(Mono.defer(() ->
Mono.just(ResponseEntity.status(HttpStatus.INTERNAL_SERVER_ERROR)
.body(Response.builder()
.status(HttpStatus.INTERNAL_SERVER_ERROR)
.message("Unknown error occurred, try again")
.build()))));
}
@Override
public Mono<T> create(Mono<T> t, Map<String, Claim> claims) {
return validate(t)
.flatMap(k -> getRepository().save(k));
}
@Override
public Flux<T> createAll(List<T> t, Map<String, Claim> claims) {
return validate(Flux.fromIterable(t))
.thenMany(getRepository().saveAll(t));
}
}
最后是我的 IBaseService 界面
public interface IBaseService<T extends BaseModel, V extends BaseDto> {
Mono<ResponseEntity<?>> create(V v, Optional<String> authorizationHeader);
Mono<T> create(Mono<T> t, Map<String, Claim> claims);
Flux<T> createAll(List<T> t, Map<String, Claim> claims);
}
阅读后我发现 CGLIB 问题通常是由 @Transactional 注释引起的，因为它会生成代理，解决方法是将它 @Transactional 放在父级上其中我有，但应用程序重新启动后仍然弹出错误。
好的，所以我找到了罪魁祸首，原来是 Java 9 module-info.java，我遇到了使 RabbitMq 工作的问题，所有文件都已正确导入，但它指向说错误来自我的 module-info.java 所以我删除了它，在删除它之后我没有遇到这个问题（并且 RabbitMq 也工作过），根据我的理解，它们是内部的 类 没有被放置在需要访问我的 类 的允许列表上，并且由于该应用程序一直失败，该应用程序从那时起一直在运行，没有任何问题。
我有一个 Webflux 应用程序，在使用几分钟后会自动重启，sometimes I can use it for a couple of hours 然后突然重启，当它重启时会弹出一个错误，提示重复 EnhancerBySpringCGLIB。我知道之前有人问过这个问题，我尝试了建议的解决方案，但 none 奏效了。下面是我的日志

这就是我的 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())
.flatMap(country -> Mono.just(country.toBuilder()
.name(countryDto.getName())
.build()));
}
@Override
public IJWTUtil getJwtUtil() {
return jwtUtil;
}
}
我的ICountryService界面
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, V> {
@Getter
private final ModelMapper modelMapper;
abstract public E getRepository();
public abstract Mono<T> createModel(V v, Map<String, Claim> claims);
public abstract Mono<T> createUpdateModel(V v, Map<String, Claim> claims);
public abstract IJWTUtil getJwtUtil();
public Mono<T> validate(Mono<T> t) {
return t;
}
public Flux<T> validate(Flux<T> t) {
return t;
}
public BaseService() {
modelMapper = new ModelMapper();
}
@Override
public Mono<ResponseEntity<?>> create(V v, Optional<String> authorizationHeader) {
Map<String, Claim> claims = authorizationHeader.map(mAuthorizationHeader -> getJwtUtil().getAllClaims(mAuthorizationHeader)).orElse(new HashMap<>());
Mono<T> model = this.createModel(v, claims);
return create(model, claims)
.flatMap(__ -> Mono.<ResponseEntity<?>>just(ResponseEntity
.status(HttpStatus.CREATED)
.body(Response.builder()
.payLoad(HttpStatus.CREATED)
.build())))
.switchIfEmpty(Mono.defer(() ->
Mono.just(ResponseEntity.status(HttpStatus.INTERNAL_SERVER_ERROR)
.body(Response.builder()
.status(HttpStatus.INTERNAL_SERVER_ERROR)
.message("Unknown error occurred, try again")
.build()))));
}
@Override
public Mono<T> create(Mono<T> t, Map<String, Claim> claims) {
return validate(t)
.flatMap(k -> getRepository().save(k));
}
@Override
public Flux<T> createAll(List<T> t, Map<String, Claim> claims) {
return validate(Flux.fromIterable(t))
.thenMany(getRepository().saveAll(t));
}
}
最后是我的 IBaseService 界面
public interface IBaseService<T extends BaseModel, V extends BaseDto> {
Mono<ResponseEntity<?>> create(V v, Optional<String> authorizationHeader);
Mono<T> create(Mono<T> t, Map<String, Claim> claims);
Flux<T> createAll(List<T> t, Map<String, Claim> claims);
}
阅读后我发现 CGLIB 问题通常是由 @Transactional 注释引起的，因为它会生成代理，解决方法是将它 @Transactional 放在父级上其中我有，但应用程序重新启动后仍然弹出错误。
好的，所以我找到了罪魁祸首，原来是 Java 9 module-info.java，我遇到了使 RabbitMq 工作的问题，所有文件都已正确导入，但它指向说错误来自我的 module-info.java 所以我删除了它，在删除它之后我没有遇到这个问题（并且 RabbitMq 也工作过），根据我的理解，它们是内部的 类 没有被放置在需要访问我的 类 的允许列表上，并且由于该应用程序一直失败，该应用程序从那时起一直在运行，没有任何问题。
