AdvisedSupport (Spring Framework 5.3.5 API)

java.lang.Object
- org.springframework.aop.framework.ProxyConfig
- - org.springframework.aop.framework.AdvisedSupport

All Implemented Interfaces:

Serializable, Advised, TargetClassAware

Direct Known Subclasses:

ProxyCreatorSupport
```
public class AdvisedSupport
extends ProxyConfig
implements Advised
```
Base class for AOP proxy configuration managers. These are not themselves AOP proxies, but subclasses of this class are normally factories from which AOP proxy instances are obtained directly.
This class frees subclasses of the housekeeping of Advices and Advisors, but doesn't actually implement proxy creation methods, which are provided by subclasses.
This class is serializable; subclasses need not be. This class is used to hold snapshots of proxies.

```
    Description copied from interface: Advised
    
    Change the TargetSource used by this Advised object.
    Only works if the configuration isn't frozen.
    
    Specified by:
    
    setTargetSource in interface Advised
    
    Parameters:
    
    targetSource - new TargetSource to use

public void setTargetClass(@Nullable
                           Class<?> targetClass)
```
    Set a target class to be proxied, indicating that the proxy should be castable to the given class.
    Internally, an EmptyTargetSource for the given target class will be used. The kind of proxy needed will be determined on actual creation of the proxy.
    This is a replacement for setting a "targetSource" or "target", for the case where we want a proxy based on a target class (which can be an interface or a concrete class) without having a fully capable TargetSource available.
