Než som sa pridal spring-data-start-jpa
a h2-database
závislostí, bolo hádzanie tieto chyby.
Ja povolené Axon auto-konfiguráciu do jeho vec.
Tu je trasovanie zásobníka som dostal:
org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'postProductsController': Unsatisfied dependency expressed through method 'setCommandGateway' parameter 0; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'commandGateway' defined in class path resource [org/axonframework/springboot/autoconfig/AxonAutoConfiguration.class]: Unsatisfied dependency expressed through method 'commandGateway' parameter 0; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'axonServerCommandBus' defined in class path resource [org/axonframework/springboot/autoconfig/AxonServerAutoConfiguration.class]: Unsatisfied dependency expressed through method 'axonServerCommandBus' parameter 2; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'commandBus' defined in class path resource [org/axonframework/springboot/autoconfig/AxonAutoConfiguration.class]: Unsatisfied dependency expressed through method 'commandBus' parameter 1; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.axonframework.spring.config.AxonConfiguration': Cannot resolve reference to bean 'org.axonframework.config.Configurer' while setting constructor argument; nested exception is org.springframework.beans.factory.BeanCurrentlyInCreationException: Error creating bean with name 'org.axonframework.config.Configurer': Requested bean is currently in creation: Is there an unresolvable circular reference?

Tu je ukážka radič som sa vytvorili:
@RestController
@RequestMapping(path = "/api/v1/products")
public class PostProductsController {
private CommandGateway commandGateway;
@Autowired
public void setCommandGateway(CommandGateway commandGateway) {
this.commandGateway = commandGateway;
}
@PostMapping
public String createProduct(@RequestBody CreateProductRestModel createProductRestModel){
CreateProductCommand createProductCommand = CreateProductCommand.builder()
.price(createProductRestModel.getPrice())
.quantity(createProductRestModel.getQuantity())
.title(createProductRestModel.getTitle())
.productId(UUID.randomUUID().toString())
.build();
String returnValue;
try{
returnValue = commandGateway.sendAndWait(createProductCommand);
} catch (Exception e){
returnValue = e.getLocalizedMessage();
}
return returnValue;
}
}
Potom, čo som pridal závislostí, začalo hádzať tieto chyby:
