Spring-boot-1.3.1
Resin-4.0.47
部署Spring?Boot到Resin后，出現(xiàn)異常：

異常的大概問題就是菊匿，創(chuàng)建'userWoundedArmyMapper'時失敗跌捆，因為無法注入sqlSessionFactory失敗抄瓦。
而sqlSessionFactory在MybatisAutoConfiguration中創(chuàng)建的煞额，故需要先創(chuàng)建MybatisAutoConfiguration栈顷，在創(chuàng)MybatisAutoConfiguration時失敗，因為無法注入MybatisProperties漓概。
創(chuàng)建MybatisProperties后漾月，初始化MybatisProperties失敗，因為它的初始化是由ConfigurationPropertiesBindingPostProcessor進行初始化的胃珍，在ConfigurationPropertiesBindingPostProcessor中梁肿，使用了Javax?Validation，在應(yīng)用中使用了Hibernate的Validation實現(xiàn)觅彰，找不到ConfigurationImpl的定義吩蔑。
進行遠(yuǎn)程Debug，并結(jié)合jvminspect.jar填抬，發(fā)現(xiàn)Resin/lib目錄下存在validation-api和hibernate-validator烛芬，且版本與項目引用的版本不一致。
ConfigurationImpl類飒责，發(fā)現(xiàn)靜態(tài)代碼塊
static{
Version.touch();
}
private static final Log?log?=?LoggerFactory.make();
LoggerFactory類的make方法：
public static Log?make()?{
Throwable?t?=newThrowable();
StackTraceElement?directCaller?=?t.getStackTrace()[1];
returnLogger.getMessageLogger(?Log.class,?directCaller.getClassName()?);
}
其中使用了jboss的logging赘娄，很有可能是jboss?logging存在多個版本導(dǎo)致ConfigurationImpl靜態(tài)代碼塊執(zhí)行失敗，發(fā)現(xiàn)Resin/lib下存在jboss-logging宏蛉，于是問題明朗了遣臼。
由于重復(fù)的validation-api、hibernate-validator檐晕、jboss-logging暑诸，導(dǎo)致加載ConfigurationImpl后進行靜態(tài)代碼塊執(zhí)行時，引用jboss?logger錯誤辟灰，導(dǎo)致ConfigurationImpl出現(xiàn)NoClassDefFoundError个榕。
解決方法：刪除Resin/lib下的validation-api、hibernate-validator芥喇、jboss-loggingjar包西采。
之后，又出現(xiàn)了另外的問題：
java.lang.IndexOutOfBoundsException:?Index:?0,?Size:?0
at?java.util.ArrayList.rangeCheck(ArrayList.java:635)?~[na:1.7.0_67]
at?java.util.ArrayList.get(ArrayList.java:411)?~[na:1.7.0_67]
at?com.caucho.server.webapp.WebApp.hasListener(WebApp.java:2197)?~[resin.jar:4.0.47]
at?com.caucho.server.webapp.WebApp.addListenerObject(WebApp.java:2148)?~[resin.jar:4.0.47]
at?com.caucho.server.webapp.WebApp.addListener(WebApp.java:2108)?~[resin.jar:4.0.47]
經(jīng)過查看Resin源碼继控，發(fā)現(xiàn)這是resin-4.0.45版本中引入的bug：
/**
*?Returns?true?if?a?listener?with?the?given?type?exists.
*/
public?boolean?hasListener(ArrayList?listeners,?Class?listenerClass)
{
for?(int?i?=?0;?i?<?listeners.size();?i++)?{
Object?listener?=?_listeners.get(i);
if?(listener.getClass().equals(listenerClass))?{
return?true;
}
}
return?false;
}
其中Object?listener?=?_listeners.get(i);的_listeners使用了類屬性械馆，而不是參數(shù)listeners，導(dǎo)致異常武通，這個BUG只能等后續(xù)版本修復(fù)霹崎。
于是，我下載了未引入這個BUG的Resin-4.0.44版本冶忱，運行之后尾菇，又發(fā)現(xiàn)了新的問題：
Custom?bean?class?'{0}'?is?not?public.??Bean?classes?must?be?public,?concrete,?and?have?a?zero-argument?constructor.
經(jīng)過查看Resin源碼，發(fā)現(xiàn)com.caucho.server.dispatch.FilterConfigImpl的setFilterClass方法：
@DisableConfig
public?void?setFilterClass(Class?filterClass)
{
this._filterClass?=?filterClass;
Config.validate(this._filterClass,?Filter.class);
}
這又是Resin的一個BUG，當(dāng)直接添加Filter對象到ServletContext時派诬，Resin還會去驗證Filter的CLass是不是public的類劳淆。這個Bug在Resin-4.0.46中修復(fù)了。
servlet:?drop?instantiation?check?for?instances?of?servlets?and?filters?(#5934)
@DisableConfig
public?void?setFilterClass(Class?filterClass)
{
_filterClass?=?filterClass;
if?(_filter?==?null)
Config.validate(_filterClass,?Filter.class);
}
為了解決這個問題默赂，必須使用Resin-4.0.46以后的版本沛鸵。
綜合Resin上訴2個BUG，導(dǎo)致Resin目前沒有一個版本可以完美支持Spring?Boot缆八，只能換Tomcat和Jetty了曲掰。
