Method Examples

getAnnotation

AutowiredInjectionPointDependencyResolver resolver = new AutowiredInjectionPointDependencyResolver();
  // Given: @Bean public User user(@Autowired MyDependency[] deps) { ... }
  Method method = MethodUtils.findMethod(Config.class, "user", MyDependency[].class);
  Parameter parameter = method.getParameters()[0];
  Autowired autowired = resolver.getAnnotation(parameter);
  // autowired is non-null since @Autowired is present on the parameter

resolve

AutowiredInjectionPointDependencyResolver resolver = new AutowiredInjectionPointDependencyResolver();
  resolver.setBeanFactory(beanFactory);
  // Given: @Autowired private Optional<List<MyDependency>> test;
  Field field = ReflectionUtils.findField(Config.class, "test");
  Set<String> dependentBeanNames = new LinkedHashSet<>();
  resolver.resolve(field, beanFactory, dependentBeanNames);
  // dependentBeanNames contains bean names matching the field type

resolve

AutowiredInjectionPointDependencyResolver resolver = new AutowiredInjectionPointDependencyResolver();
  resolver.setBeanFactory(beanFactory);
  // Given: @Autowired public Config(Map<String, MyDependency> test) { }
  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

getAnnotation

public Autowired getAnnotation(Parameter parameter)

Get the Autowired annotation from the given Parameter.

First looks for @Autowired directly on the parameter. If not found, falls back to looking for @Autowired on the declaring method or constructor.

Example Usage

`AutowiredInjectionPointDependencyResolver resolver = new AutowiredInjectionPointDependencyResolver();
  // Given: @Bean public User user(@Autowired MyDependency[] deps) { ... `
  Method method = MethodUtils.findMethod(Config.class, "user", MyDependency[].class);
  Parameter parameter = method.getParameters()[0];
  Autowired autowired = resolver.getAnnotation(parameter);
  // autowired is non-null since @Autowired is present on the parameter
}

resolve

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

Resolve the dependent bean names from the given Field if it is annotated with Autowired. Fields without the annotation are silently skipped.

Example Usage

`AutowiredInjectionPointDependencyResolver resolver = new AutowiredInjectionPointDependencyResolver();
  resolver.setBeanFactory(beanFactory);
  // Given: @Autowired private Optional> test;
  Field field = ReflectionUtils.findField(Config.class, "test");
  Set dependentBeanNames = new LinkedHashSet<>();
  resolver.resolve(field, beanFactory, dependentBeanNames);
  // dependentBeanNames contains bean names matching the field type
`

resolve

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

Resolve the dependent bean names from the given Parameter if it or its declaring method/constructor is annotated with Autowired. Parameters without the annotation are silently skipped.

Example Usage

`AutowiredInjectionPointDependencyResolver resolver = new AutowiredInjectionPointDependencyResolver();
  resolver.setBeanFactory(beanFactory);
  // Given: @Autowired public Config(Map test) { `
  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
}
