The spring boot exception org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name defined in file: Unsatisfied dependency expressed through field occurs when a problem occurs when a bean auto-wired on other beans that have not bean loaded in the spring boot application context. The exception org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name defined in file: Unsatisfied dependency expressed through constructor parameter 0 occurs if the constructor parameter is auto-wired with a bean that have not bean loaded in the spring boot application
If the bean is auto-wired in another bean, the bean must be loaded in the spring boot application context. Otherwise, the bean will not be auto-wired for the bean. The bean is not loaded in the context for the various reasons such as bean is not available, could not load, exception occurs while loading, exception occurs while initialising etc. The nested exception will show the reason for the exception org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name defined in file.
The nested exception will help you to fix UnsatisfiedDependencyException. The following list describes the common root causes that are seen in the nested exception.
NoSuchBeanDefinitionException: No qualifying bean of type
This exception occurs when the bean is not available or defined while auto-wired in another class.
s.c.a.AnnotationConfigApplicationContext : Exception encountered during context initialization – cancelling refresh attempt: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name ‘zoo’: Unsatisfied dependency expressed through field ‘lion’; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type ‘com.yawintutor.Lion’ available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}
If the root cause exception is displayed as No qualifying bean of type then follow the link below to resolve this exception.
NoSuchBeanDefinitionException: No qualifying bean of type
BeanCurrentlyInCreationException: Error creating bean with name: Requested bean is currently in creation
This exception happens when two beans are in circular dependences with each other.
s.c.a.AnnotationConfigApplicationContext : Exception encountered during context initialization – cancelling refresh attempt: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name ‘department’ defined in file [/SpringBootBean/target/classes/com/yawintutor/Department.class]: Unsatisfied dependency expressed through constructor parameter 0; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name ‘lion’ defined in file [/SpringBootBean/target/classes/com/yawintutor/Lion.class]: Unsatisfied dependency expressed through constructor parameter 0; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name ‘tiger’ defined in file [/SpringBootBean/target/classes/com/yawintutor/Tiger.class]: Unsatisfied dependency expressed through constructor parameter 0; nested exception is org.springframework.beans.factory.BeanCurrentlyInCreationException: Error creating bean with name ‘lion’: Requested bean is currently in creation: Is there an unresolvable circular reference?
If the root cause exception is displayed as Requested bean is currently in creation then follow the link below to resolve this exception.
BeanCurrentlyInCreationException: Error creating bean with name: Requested bean is currently in creation
NoUniqueBeanDefinitionException: No qualifying bean of type available: expected single matching bean but found
This exception occurs when the bean is auto-wired that matches two or more loaded beans in the spring boot application context.
s.c.a.AnnotationConfigApplicationContext : Exception encountered during context initialization – cancelling refresh attempt: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name ‘zoo’: Unsatisfied dependency expressed through field ‘animal’; nested exception is org.springframework.beans.factory.NoUniqueBeanDefinitionException: No qualifying bean of type ‘com.yawintutor.Animal’ available: expected single matching bean but found 2: lion,tiger
If the root cause exception is displayed as expected single matching bean but found then follow the link below to resolve this exception.
