Consider injecting the bean as one of its interfaces or forcing the use of CGLib-based proxies by setting proxyTargetClass=true on @EnableAsync and/or @EnableCaching.

问题描述

Spring Boot 项目，启用事务支持时出现以下错误：

Error starting ApplicationContext. To display the auto-configuration report re-run your application with ‘debug’ enabled.

Description:

The bean ‘departmentDao’ could not be injected as a ‘com.wanyu.fams.dao.DepartmentDao’ because it is a JDK dynamic proxy that implements:

Action:

Consider injecting the bean as one of its interfaces or forcing the use of CGLib-based proxies by setting proxyTargetClass=true on @EnableAsync and/or @EnableCaching.

也就是添加了一个注解：@Transactional // 启用事务处理，启动的时候就报错了。

解决方法
在 application.properties 或者 application.yml 配置文件中添加配置：

以下为 application.properties 中的配置方法：

解决问题

spring.aop.proxy-target-class=true

application.yml 写法有点不同：

spring:
  aop:
    proxy-target-class: true

失败的尝试

有文章指出：在springboot启动类中添加如下代码，最终解决问题，我尝试失败，错误依旧！

@Bean
    @ConditionalOnMissingBean
    public DefaultAdvisorAutoProxyCreator defaultAdvisorAutoProxyCreator() {
        DefaultAdvisorAutoProxyCreator daap = new DefaultAdvisorAutoProxyCreator();
        daap.setProxyTargetClass(true);
        return daap;
    }
