The bean \'xxx\' could not be injected as a \'com.zp.demo.service.xxx\' because it is a JDK dynamic proxy that implements: com.zp.demo.service.ReportService

springboot 使用事务报错

报错信息：

Description:

The bean \'reportImpl\' could not be injected as a \'com.zp.demo.service.Impl.ReportImpl\' because it is a JDK dynamic proxy that implements:
    com.zp.demo.service.ReportService


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.

解决方法：

①在启动类上添加@EnableAspectJAutoProxy(proxyTargetClass = true)注解：

@Configuration
@SpringBootApplication
@EnableTransactionManagement(proxyTargetClass = true) //开始事务
public class DemoApplication {



    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }

②在报错的service上添加@Scope(proxyMode = ScopedProxyMode.TARGET_CLASS)注解：

@Service
@Scope(proxyMode = ScopedProxyMode.TARGET_CLASS)
public class ReportImpl{
 
 

}

 

 分析ScopedProxyMode可以发现不同的参数值就对应了不同的代理类型。

public enum ScopedProxyMode {
 
    /**
     * Default typically equals {@link #NO}, unless a different default
     * has been configured at the component-scan instruction level.
     */
    DEFAULT,
 
    /**
     * Do not create a scoped proxy.
     * <p>This proxy-mode is not typically useful when used with a
     * non-singleton scoped instance, which should favor the use of the
     * {@link #INTERFACES} or {@link #TARGET_CLASS} proxy-modes instead if it
     * is to be used as a dependency.
     */
    NO,
 
    /**
     * Create a JDK dynamic proxy implementing <i>all</i> interfaces exposed by
     * the class of the target object.
     */
    INTERFACES,
 
    /**
     * Create a class-based proxy (uses CGLIB).
     */
    TARGET_CLASS;
 
}
