Usage

From source file:org.springframework.context.annotation.AutoProxyRegistrar.java

/**
 * Register, escalate, and configure the standard auto proxy creator (APC) against the
 * given registry. Works by finding the nearest annotation declared on the importing
 * {@code @Configuration} class that has both {@code mode} and {@code proxyTargetClass}
 * attributes. If {@code mode} is set to {@code PROXY}, the APC is registered; if
 * {@code proxyTargetClass} is set to {@code true}, then the APC is forced to use
 * subclass (CGLIB) proxying.//from   ww  w.j a  v a2 s  .  c  o  m
 * <p>Several {@code @Enable*} annotations expose both {@code mode} and
 * {@code proxyTargetClass} attributes. It is important to note that most of these
 * capabilities end up sharing a {@linkplain AopConfigUtils#AUTO_PROXY_CREATOR_BEAN_NAME
 * single APC}. For this reason, this implementation doesn't "care" exactly which
 * annotation it finds -- as long as it exposes the right {@code mode} and
 * {@code proxyTargetClass} attributes, the APC can be registered and configured all
 * the same.
