***************************
APPLICATION FAILED TO START
***************************

Description:

The bean 'sysDictService' could not be injected because it is a JDK dynamic proxy

The bean is of type 'com.sun.proxy.$Proxy134' and implements:
	org.springframework.aop.SpringProxy
	org.springframework.aop.framework.Advised
	org.springframework.cglib.proxy.Factory
	com.baomidou.mybatisplus.extension.service.IService
	org.springframework.core.DecoratingProxy

Expected a bean of type 'com.sozone.basis.dict.service.SysDictService' which 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.

Solution 1:

        // StartApplication.java Add this method to the project startup class
	@Bean
	@ConditionalOnMissingBean
	public DefaultAdvisorAutoProxyCreator defaultAdvisorAutoProxyCreator() {
		DefaultAdvisorAutoProxyCreator daap = new DefaultAdvisorAutoProxyCreator();
		daap.setProxyTargetClass(true);
		return daap;
	}
	

Solution 2:

// application.yml
spring:
  aop:
    proxy-target-class: true

Problem Description:

When sorting out the project framework, there was a sudden problem. The original framework did not have this problem. I don’t know if it was caused by a dependency. . .
Finally, use solution one to successfully solve the problem. The second solution could not be solved, and I also recorded it casually, maybe I will encounter it again later.
