Package net.ttddyy.observation.boot

Class SpringJdbcProxyFactory

java.lang.Object

net.ttddyy.observation.boot.SpringJdbcProxyFactory

All Implemented Interfaces:

net.ttddyy.dsproxy.proxy.JdbcProxyFactory

public class SpringJdbcProxyFactory
extends Object
implements net.ttddyy.dsproxy.proxy.JdbcProxyFactory

JdbcProxyFactory implementation using spring's ProxyFactory.

Using Spring's proxy mechanism allows other Spring-based libraries to correctly introspect and extract the underlying target object from the proxy.

This is particularly useful when Spring infrastructure components need to inspect the concrete type of a proxied object. For example, Spring Cloud's refresh scope logic checks whether a DataSource bean is a specific implementation such as HikariCP. When the DataSource is wrapped by this proxy factory, Spring can still extract the underlying target object and perform such checks correctly. (see issue#99)
