@Transactional可在抽象类上定义，且能生效

定义一个抽象类

import com.shopping.base.repository.sync.ipos.coupon.IposCzklbRepository;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.transaction.annotation.Transactional;

@Transactional(rollbackFor = Exception.class)
public abstract class AbstractHandler {
    @Autowired
    HandlerRepository HandlerRepository;
    
	public abstract void test();
    
}

继承抽象类

import org.springframework.stereotype.Component;

@Component
public class AHandler extends AbstractHandler {

    @Override
    public void test() {
        System.out.println(super.iposCzklbRepository.findAll());
    }
}

在其他地方注入

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;


@RestController
public class TestController {

	@Autowired
    private AbstractHandler handler;

  
    @GetMapping("/handler")
    public String handler() throws Exception {
        handler.test();
        return "SUCCESS";
    }
}

能够调用执行

更改一下test()方法，

super.iposCzklbRepository.deleteById(97);
int i = 1 / 0;

事务也能生效
