文档描述
当定义BarService并定义BarServiceStub时，配置如下其实是不会生效的
<dubbo:service interface="com.foo.BarService" stub="true" />

if(local !=null){ // 文档中并没有与local相关的参数解释
if(local=="true"){
local=interfaceName+"Local";
}
Class<?> localClass;
try {
localClass = ClassHelper.forNameWithThreadContextClassLoader(local);
} catch (ClassNotFoundException e) {
throw new IllegalStateException(e.getMessage(), e);
}
if(!interfaceClass.isAssignableFrom(localClass)){
throw new IllegalStateException("The local implemention class " + localClass.getName() + " not implement interface " + interfaceName);
}
}
if(stub !=null){
if(stub=="true"){ // 最坑爹的错误是这里，文档说stub="true"默认interfaceName+Local（实际是+Stub，参见下一个注释），可是这是String对象啊，如果外面stub赋值不是stub="true"的话，设置了true也不会进来，应该修改为stub.equals("true")，上面Local也一样
stub=interfaceName+"Stub"; // 这里文档中的解释有误，文档中写的是+Local，即与上面的Local一致
