Method Examples

resolve

ConstructionInjectionPointDependencyResolver resolver = new ConstructionInjectionPointDependencyResolver();
  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

ConstructionInjectionPointDependencyResolver resolver = new ConstructionInjectionPointDependencyResolver();
  resolver.setBeanFactory(beanFactory);
  Method method = MethodUtils.findMethod(Config.class, "setMyService", MyService.class);
  Set<String> dependentBeanNames = new LinkedHashSet<>();
  resolver.resolve(method, beanFactory, dependentBeanNames);
  // dependentBeanNames is empty — methods are ignored

resolve

ConstructionInjectionPointDependencyResolver resolver = new ConstructionInjectionPointDependencyResolver();
  resolver.setBeanFactory(beanFactory);
  // Given: @Autowired public Config(Map<String, MyDependency> deps) { }
  Constructor<?> constructor = ConstructorUtils.findConstructor(Config.class, Map.class);
  Parameter parameter = constructor.getParameters()[0];
  Set<String> dependentBeanNames = new LinkedHashSet<>();
  resolver.resolve(parameter, beanFactory, dependentBeanNames);
  // dependentBeanNames contains bean names matching the parameter type

Usage

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 Constructor parameters.

Example Usage

`ConstructionInjectionPointDependencyResolver resolver = new ConstructionInjectionPointDependencyResolver();
  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(Method method, ConfigurableListableBeanFactory beanFactory, Set<String> dependentBeanNames)

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

Example Usage

`ConstructionInjectionPointDependencyResolver resolver = new ConstructionInjectionPointDependencyResolver();
  resolver.setBeanFactory(beanFactory);
  Method method = MethodUtils.findMethod(Config.class, "setMyService", MyService.class);
  Set dependentBeanNames = new LinkedHashSet<>();
  resolver.resolve(method, beanFactory, dependentBeanNames);
  // dependentBeanNames is empty — methods 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 Constructor. Parameters from methods are silently skipped.

Example Usage

`ConstructionInjectionPointDependencyResolver resolver = new ConstructionInjectionPointDependencyResolver();
  resolver.setBeanFactory(beanFactory);
  // Given: @Autowired public Config(Map deps) { `
  Constructor constructor = ConstructorUtils.findConstructor(Config.class, Map.class);
  Parameter parameter = constructor.getParameters()[0];
  Set dependentBeanNames = new LinkedHashSet<>();
  resolver.resolve(parameter, beanFactory, dependentBeanNames);
  // dependentBeanNames contains bean names matching the parameter type
}
