- org.springframework.beans.factory.config.TypedStringValue
- 所有已实现的接口:
BeanMetadataElement
public class TypedStringValue extends Object implements BeanMetadataElement
Holder for a typed String value. Can be added to bean definitions in order to explicitly specify a target type for a String value, for example for collection elements.This holder will just store the String value and the target type. The actual conversion will be performed by the bean factory.

方法详细资料
setValue
public void setValue(@Nullable String value)
Set the String value.Only necessary for manipulating a registered value, for example in BeanFactoryPostProcessors.
setTargetType
public void setTargetType(Class<?> targetType)
Set the type to convert to.Only necessary for manipulating a registered value, for example in BeanFactoryPostProcessors.
getTargetType
public Class<?> getTargetType()
Return the type to convert to.
setTargetTypeName
public void setTargetTypeName(@Nullable String targetTypeName)
Specify the type to convert to.
getTargetTypeName
@Nullable public String getTargetTypeName()
Return the type to convert to.
hasTargetType
public boolean hasTargetType()
Return whether this typed String value carries a target type .
resolveTargetType
@Nullable public Class<?> resolveTargetType(@Nullable ClassLoader classLoader) throws ClassNotFoundException
Determine the type to convert to, resolving it from a specified class name if necessary. Will also reload a specified Class from its name when called with the target type already resolved.- 参数:
classLoader
- the ClassLoader to use for resolving a (potential) class name- 返回:
- the resolved type to convert to
- 抛出:
ClassNotFoundException
- if the type cannot be resolved
setSource
public void setSource(@Nullable Object source)
Set the configuration sourceObject
for this metadata element.The exact type of the object will depend on the configuration mechanism used.
getSource
@Nullable public Object getSource()
从接口复制的说明:BeanMetadataElement
Return the configuration sourceObject
for this metadata element (may benull
).- 指定者:

getSpecifiedTypeName
@Nullable public String getSpecifiedTypeName()
Return the type name as actually specified for this particular value, if any.
setDynamic
public void setDynamic()
Mark this value as dynamic, i.e. as containing an expression and hence not being subject to caching.
isDynamic
public boolean isDynamic()
Return whether this value has been marked as dynamic.
