指定事务管理器 bean 后找不到匹配的编辑器或转换策略

Question

我是新手，正在尝试创建一个 Spring5 MVC/Hibernate5 Web 应用程序，但是当我启动 Tomcat 时出现以下错误：

最初的问题与事务管理器有关，在添加事务管理器 bean 定义之前，应用程序启动正常但失败并显示错误消息，指出它无法创建事务线程。

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'customerController' defined in ServletContext resource [/WEB-INF/spring/store.xml]: Initialization of bean failed; nested exception is org.springframework.beans.ConversionNotSupportedException: Failed to convert property value of type 'com.sun.proxy.$Proxy210 implementing com.store.service.CustomerService,java.io.Serializable,org.springframework.aop.SpringProxy,org.springframework.aop.framework.Advised,org.springframework.core.DecoratingProxy' to required type 'com.store.service.CustomerServiceImpl' for property 'customerService'; nested exception is java.lang.IllegalStateException: Cannot convert value of type 'com.sun.proxy.$Proxy210 implementing com.store.service.CustomerService,java.io.Serializable,org.springframework.aop.SpringProxy,org.springframework.aop.framework.Advised,org.springframework.core.DecoratingProxy' to required type 'com.store.service.CustomerServiceImpl' for property 'customerService': no matching editors or conversion strategy found

我的 web.xml ：

我想在您的CustomerController课程中，您注入的不是接口，而是 的实现CustomerService，如下所示：public class CustomerController {&nbsp; &nbsp; @Autowired&nbsp; &nbsp; private CustomerServiceImpl customerService;}具体类是代理的，因此您应该将注入点指定为接口：public class CustomerController {&nbsp; &nbsp; @Autowired&nbsp; &nbsp; private CustomerService customerService;}
