Spring ConversionFailedException: Failed to convert from type java.util.ArrayList<?> to type java.ut...

org.springframework.core.convert.ConversionFailedException: Failed to convert from type [java.util.ArrayList<?>] to type [java.util.List<org.springframework.core.io.Resource>] for value '[/assets/]'; nested exception is org.springframework.core.convert.ConverterNotFoundException: No converter found capable of converting from type [java.util.ArrayList<?>] to type [org.springframework.core.io.Resource]

原因beanID冲突

源代码样式

<mvc:annotation-driven conversion-service="conversionService"> <mvc:message-converters> <bean class="org.springframework.http.converter.StringHttpMessageConverter" /> <bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter" /> </mvc:message-converters> </mvc:annotation-driven> <bean id="conversionService" class="org.springframework.format.support.FormattingConversionServiceFactoryBean"> <property name="formatters"> <set> <bean class="com.ivlo.crm.extend.MyDateFormatter"></bean> </set> </property> </bean> <mvc:resources mapping="/assets/**" location="/assets/" />

将conversionService 换一个ID名称 例如 conversionDateService 既可以正常运行了
