Java 重写hybris Commoni18n服务roundCurrency方法

尝试使用

Alias

覆盖

springbean

我想超越

roundCurrency

commoni18n服务的

method

OOTB定义

<alias alias="commonI18NService" name="defaultCommonI18NService"/>
<bean id="defaultCommonI18NService" class="de.hybris.platform.servicelayer.i18n.impl.DefaultCommonI18NService"  parent="abstractBusinessService">
    <property name="languageDao" ref="languageDao"/>
    <property name="currencyDao" ref="currencyDao"/>
    <property name="countryDao" ref="countryDao"/>
    <property name="regionDao" ref="regionDao"/>
    <property name="conversionStrategy" ref="conversionStrategy"/>
</bean>

注入自定义bean：-

<alias alias="commonI18NService" name="defaultCustomCommonI18NService"/>
<bean id="defaultCustomCommonI18NService" class="com.extended.service.impl.DefaultCustomCommonI18NService"  parent="defaultCommonI18NService"/>



但它在服务器启动时抛出异常

发生这种情况是因为
defaultConverterRegistry
的自动布线策略是
byType
：

<bean id="defaultConverterRegistry" ... autowire="byType" >

您如何发现问题是由
defaultConverterRegistry
引起的？我无法查看该类的源代码。假设“defaultConverterRegistry”具有公共I18N服务，如@Autowiredit在此处声明的：…\hybris\bin\platform\ext\core\resources\servicelayer-spring.xml，并且它存在于您提供的堆栈跟踪中，如果您想查看e DefaultModelConverterRegistry.class的源您需要使用java反编译器。我没有找到任何与
DefaultModelConverterRegistry
相关的stacktrace，我也尝试使用反编译器检查
DefaultModelConverterRegistry
的源代码，但没有运气。我假设这个类有自动连接的
Commoni18n服务
，它是造成问题的原因。
<bean id="defaultConverterRegistry" ... autowire="byType" >

<bean id="defaultCustomCommonI18NService" class="com.extended.service.impl.DefaultCustomCommonI18NService"  parent="defaultCommonI18NService" primary="true" />
