![]() No qualifying bean of type '' available:Įxpected at least 1 bean which qualifies as autowire candidate. Unsatisfied dependency expressed through field 'lion' nested exception is } Output s.c.a.AnnotationConfigApplicationContext : Exception encountered during context initialization - cancelling refresh attempt: The Lion class is not available as spring boot bean, the NoSuchBeanDefinitionException has occurred. In the example below, the Zoo class is trying to inject the Lion class into it. If the java class is trying to inject another class and the injection class is not available at the spring boot ApplicationContext, the NoSuchBeanDefinitionException exception will be thrown. Solution 1 – Bean Not Available in ApplicationContext The reason could be either that the bean is not available or that it is not possible to locate the bean or that an error occurred while injecting the bean. If any bean is not available or unable to inject a bean, The exception NoSuchBeanDefinitionException is thrown. Spring boot loads all the beans into the ApplicationContext and dependent beans are injected. Dependency annotations: Causeĭependency injection is one of the features of the spring boot. If BeanFactory unable to load any java bean, this exception “.NoSuchBeanDefinitionException: No qualifying bean of type available” is thrown in the console log at the start of the spring boot application.Įxception s.c.a.AnnotationConfigApplicationContext : Exception encountered during context initialization - cancelling refresh attempt: .UnsatisfiedDependencyException: Error creating bean with name 'zoo': Unsatisfied dependency expressed through field 'lion' nested exception is .NoSuchBeanDefinitionException: No qualifying bean of type '' available: expected at least 1 bean which qualifies as autowire candidate. ![]() In spring boot, BeanFactory loads all the java beans in the spring boot application context. The java class should be configured with annotations like Or the bean class can be annotated by in the class. ![]() If the Java class is not loaded in the context of the spring boot, the exception will be thrown. The spring boot application can insert the bean either by class type or by Java naming convention. If none of them matches, the exception .NoSuchBeanDefinitionException: No qualifying bean of type will be thrown. If the bean is not available when the spring boot bean is annotated by from the spring boot ApplicationContext, this exception will be thrown from the application. The spring boot exception .NoSuchBeanDefinitionException: No qualifying bean of type available and .NoSuchBeanDefinitionException: No qualifying bean of type defined occurs when the bean is not available or defined while auto-wired in another class.
