Method Detail

init

public void init()

init

public void init(java.lang.String version)

registerResourceListeners

@OnResourceFileEvent(path="/",
                     filter=".*.xml",
                     events=MODIFY)
public void registerResourceListeners(java.net.URL url)

registerBasePackageFromConfiguration

public void registerBasePackageFromConfiguration()

register base package prefix from configuration file

registerComponentScanBasePackage

public void registerComponentScanBasePackage(java.lang.String basePackage)

Register both hotswap transformer AND watcher - in case of new file the file is not known to JVM and hence no hotswap is called. The file may even exist, but until is loaded by Spring it will not be known by the JVM. File events are processed only if the class is not known to the classloader yet.

Parameters:

basePackage - only files in a basePackage

register

@OnClassLoadEvent(classNameRegexp="org.springframework.beans.factory.support.DefaultListableBeanFactory")
public static void register(org.hotswap.agent.javassist.CtClass clazz)
                     throws org.hotswap.agent.javassist.NotFoundException,
                            org.hotswap.agent.javassist.CannotCompileException

Plugin initialization is after Spring has finished its startup and freezeConfiguration is called. This will override freeze method to init plugin - plugin will be initialized and the configuration remains unfrozen, so bean (re)definition may be done by the plugin.

Throws:

org.hotswap.agent.javassist.NotFoundException

org.hotswap.agent.javassist.CannotCompileException

cglibAopProxyDisableCache

@OnClassLoadEvent(classNameRegexp="org.springframework.aop.framework.CglibAopProxy")
public static void cglibAopProxyDisableCache(org.hotswap.agent.javassist.CtClass ctClass)
                                      throws org.hotswap.agent.javassist.NotFoundException,
                                             org.hotswap.agent.javassist.CannotCompileException

Throws:

org.hotswap.agent.javassist.NotFoundException

org.hotswap.agent.javassist.CannotCompileException
