我是靠谱客的博主冷静魔镜，最近开发中收集的这篇文章主要介绍no matching editors or conversion strategy found 的解决办法，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

错误的具体情况如下：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'signInService' defined in ServletContext resource [/WEB-INF/applicationContext-beans.xml]: Initialization of bean failed; nested exception is org.springframework.beans.ConversionNotSupportedException: Failed to convert property value of type 'com.sun.proxy.$Proxy55 implementing com.moment.dao.userInfo.SignInDaoImpl,org.springframework.aop.SpringProxy,org.springframework.aop.framework.Advised' to required type 'com.moment.dao.userInfo.SignInDao' for property 'signInDao'; nested exception is java.lang.IllegalStateException: Cannot convert value of type [com.sun.proxy.$Proxy55 implementing com.moment.dao.userInfo.SignInDaoImpl,org.springframework.aop.SpringProxy,org.springframework.aop.framework.Advised] to required type [com.moment.dao.userInfo.SignInDao] for property 'signInDao': no matching editors or conversion strategy found

额，贴上错误后看着，总觉得怪怪的，还是截图吧：

上面是错误，解决办法，很简单：

<aop:config proxy-target-class="true"> ，表示可以用类注入：

如我的配置文件：

  <tx:advice transaction-manager="transactionManager" id="tm">
		<tx:attributes>
			<tx:method name="get*" read-only="true" propagation="REQUIRED"/>
			<tx:method name="query*" read-only="true" propagation="REQUIRED"/>
		</tx:attributes>
	</tx:advice>
	
	<aop:config proxy-target-class="true">
		<aop:pointcut expression="execution(* com.moment.dao.*.*(..))" id="tp"/>
		<aop:advisor advice-ref="tm" id="ta" pointcut-ref="tp"/>
	</aop:config>
