Describe what happened

使用@DSTransactional发生死循环，代码如下

package com.baomidou.samples.druid.test;

import com.baomidou.samples.druid.DruidApplication;
import com.baomidou.samples.druid.service.impl.TxService;
import org.junit.jupiter.api.Test;
import org.springframework.boot.test.context.SpringBootTest;

import javax.annotation.Resource;

/**
 * @author sunyj
 * @date 2024/1/14 20:42
 */
@SpringBootTest(classes = DruidApplication.class)
public class TxTest {
    @Resource
    private TxService txService;

    @Test
    public void testTx() {
        txService.tx();
    }
}

package com.baomidou.samples.druid.service.impl;

import com.baomidou.dynamic.datasource.annotation.DSTransactional;
import com.baomidou.dynamic.datasource.tx.TransactionContext;
import org.springframework.context.annotation.Lazy;
import org.springframework.stereotype.Service;
import org.springframework.transaction.support.TransactionSynchronization;

import javax.annotation.Resource;

@Service
public class TxService {

    @Lazy
    @Resource
    private TxService txService;

    @DSTransactional
    public void tx() {
        System.out.println("method tx");

        TransactionContext.registerSynchronization(new TransactionSynchronization() {
            @Override
            public void afterCommit() {
                txService.txAfterCommit();
            }
        });
    }

    @DSTransactional
    public void txAfterCommit() {
        System.out.println("method txAfterCommit");
    }
}

使用 @Transactional ， afterCommit只会调用一次, 代码如下

package com.baomidou.samples.druid.test;

import com.baomidou.samples.druid.DruidApplication;
import com.baomidou.samples.druid.service.impl.TxService;
import org.junit.jupiter.api.Test;
import org.springframework.boot.test.context.SpringBootTest;

import javax.annotation.Resource;

/**
 * @author sunyj
 * @date 2024/1/14 20:42
 */
@SpringBootTest(classes = DruidApplication.class)
public class TxTest {
    @Resource
    private TxService txService;

    @Test
    public void testTx() {
        txService.tx();
    }
}

package com.baomidou.samples.druid.service.impl;

import org.springframework.context.annotation.Lazy;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
import org.springframework.transaction.support.TransactionSynchronization;
import org.springframework.transaction.support.TransactionSynchronizationManager;

import javax.annotation.Resource;

@Service
public class TxService {

    @Lazy
    @Resource
    private TxService txService;

    @Transactional
    public void tx() {
        System.out.println("method tx");

        TransactionSynchronizationManager.registerSynchronization(new TransactionSynchronization() {
            @Override
            public void afterCommit() {
                txService.txAfterCommit();
            }
        });
    }

    @Transactional
    public void txAfterCommit() {
        System.out.println("method txAfterCommit");
    }
}

Expected Result: 和Spring的一致

Actual Result: 死循环

If there is an exception,or aop invalid,please attach the exception trace:

Steps to reproduce

• Step 1

• Step 2

• Step 3

现在的事务模板同一线程事务传播会在finally里invokeAfterCompletion清除此线程同步属性，确实可能存在aftercommit再套事务出现这个情况 @huayanYu 指派我吧，晚上或者明天修一下
