BeanDefinitionVisitor

public BeanDefinitionVisitor(org.springframework.util.StringValueResolver valueResolver)

Create a new BeanDefinitionVisitor, applying the specified value resolver to all bean metadata values.

参数:

valueResolver - the StringValueResolver to apply

BeanDefinitionVisitor

protected BeanDefinitionVisitor()

Create a new BeanDefinitionVisitor for subclassing. Subclasses need to override the resolveStringValue(java.lang.String) method.

方法详细资料

visitBeanDefinition

public void visitBeanDefinition(BeanDefinition beanDefinition)

Traverse the given BeanDefinition object and the MutablePropertyValues and ConstructorArgumentValues contained in them.

参数:

beanDefinition - the BeanDefinition object to traverse
