Method Examples

resolve

BeanMethodInjectionPointDependencyResolver resolver = new BeanMethodInjectionPointDependencyResolver();
  resolver.setBeanFactory(beanFactory);
  Field field = ReflectionUtils.findField(Config.class, "myField");
  Set<String> dependentBeanNames = new LinkedHashSet<>();
  resolver.resolve(field, beanFactory, dependentBeanNames);
  // dependentBeanNames is empty — fields are ignored

resolve

BeanMethodInjectionPointDependencyResolver resolver = new BeanMethodInjectionPointDependencyResolver();
  resolver.setBeanFactory(beanFactory);
  Constructor<?> constructor = ConstructorUtils.findConstructor(Config.class, Map.class);
  Set<String> dependentBeanNames = new LinkedHashSet<>();
  resolver.resolve(constructor, beanFactory, dependentBeanNames);
  // dependentBeanNames is empty — constructors are ignored

resolve

BeanMethodInjectionPointDependencyResolver resolver = new BeanMethodInjectionPointDependencyResolver();
  resolver.setBeanFactory(beanFactory);
  // Given: @Bean public User user(@Autowired MyDependency[] deps) { ... }
  Method method = MethodUtils.findMethod(Config.class, "user", MyDependency[].class);
  Parameter parameter = method.getParameters()[0];
  Set<String> dependentBeanNames = new LinkedHashSet<>();
  resolver.resolve(parameter, beanFactory, dependentBeanNames);
  // dependentBeanNames contains bean names matching MyDependency

Usage

Maven Dependency

Method Details

resolve

public void resolve(Field field, ConfigurableListableBeanFactory beanFactory, Set<String> dependentBeanNames)

No-op implementation. Field injection points are not resolved by this resolver since it only handles Bean @Bean method parameters.

Example Usage

`BeanMethodInjectionPointDependencyResolver resolver = new BeanMethodInjectionPointDependencyResolver();
  resolver.setBeanFactory(beanFactory);
  Field field = ReflectionUtils.findField(Config.class, "myField");
  Set dependentBeanNames = new LinkedHashSet<>();
  resolver.resolve(field, beanFactory, dependentBeanNames);
  // dependentBeanNames is empty — fields are ignored
`

resolve

public void resolve(Constructor constructor, ConfigurableListableBeanFactory beanFactory, Set<String> dependentBeanNames)

No-op implementation. Constructor injection points are not resolved by this resolver since it only handles Bean @Bean method parameters.

Example Usage

`BeanMethodInjectionPointDependencyResolver resolver = new BeanMethodInjectionPointDependencyResolver();
  resolver.setBeanFactory(beanFactory);
  Constructor constructor = ConstructorUtils.findConstructor(Config.class, Map.class);
  Set dependentBeanNames = new LinkedHashSet<>();
  resolver.resolve(constructor, beanFactory, dependentBeanNames);
  // dependentBeanNames is empty — constructors are ignored
`

resolve

public void resolve(Parameter parameter, ConfigurableListableBeanFactory beanFactory, Set<String> dependentBeanNames)

Resolve the dependent bean names from the given Parameter only if the parameter belongs to a Method annotated with Bean @Bean. Parameters from non-@Bean methods and constructors are silently skipped.

Example Usage

`BeanMethodInjectionPointDependencyResolver resolver = new BeanMethodInjectionPointDependencyResolver();
  resolver.setBeanFactory(beanFactory);
  // Given: @Bean public User user(@Autowired MyDependency[] deps) { ... `
  Method method = MethodUtils.findMethod(Config.class, "user", MyDependency[].class);
  Parameter parameter = method.getParameters()[0];
  Set dependentBeanNames = new LinkedHashSet<>();
  resolver.resolve(parameter, beanFactory, dependentBeanNames);
  // dependentBeanNames contains bean names matching MyDependency
}
