springboot 使用事務報錯
報錯信息：
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.
解決方法：
①在啓動類上添加@EnableAspectJAutoProxy(proxyTargetClass = true)註解：
@Configuration
@SpringBootApplication
@EnableTransactionManagement(proxyTargetClass = true) //開始事務
public class DemoApplication {
public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
}
②在報錯的service上添加@Scope(proxyMode = ScopedProxyMode.TARGET_CLASS)註解：
@Service
@Scope(proxyMode = ScopedProxyMode.TARGET_CLASS)
public class ReportImpl{
}
分析ScopedProxyMode可以發現不同的參數值就對應了不同的代理類型。
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;
}
