PrioritizedParameterNameDiscoverer (Spring Framework 4.3.30.RELEASE API)

java.lang.Object
- org.springframework.core.PrioritizedParameterNameDiscoverer

所有已实现的接口:
ParameterNameDiscoverer
直接已知子类:
DefaultParameterNameDiscoverer
```
public class PrioritizedParameterNameDiscoverer
extends Object
implements ParameterNameDiscoverer
```
ParameterNameDiscoverer implementation that tries several discoverer delegates in succession. Those added first in the addDiscoverer method have highest priority. If one returns null, the next will be tried.
The default behavior is to return null if no discoverer matches.
