同一事物内是可见的，你这个问题可能不是事务导致的，有种可能是你提交的数据库是写数据库，你读的数据库是读库，在你读的时候读库和写库还没有同步，也会出现明明提交了但是还是读不到的问题。你具体在看下吧。

我解决了, 正是事务配置问题。
经过琢磨研究，我把事务配置修改成如下解决了:

package com.hl.core.conf;

import org.springframework.aop.framework.autoproxy.BeanNameAutoProxyCreator;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.transaction.PlatformTransactionManager;
import org.springframework.transaction.interceptor.TransactionInterceptor;

import java.util.Properties;

//@Component
@Configuration
public class TxConfig2 {
    @Autowired
    private PlatformTransactionManager transactionManager;

    @Bean(name = "txAdvice")
    public TransactionInterceptor getAdvisor() throws Exception {
        System.out.println("transactionManager = " + transactionManager);
        Properties properties = new Properties();
        properties.setProperty("init*", "PROPAGATION_REQUIRED,-Exception");
        properties.setProperty("add*", "PROPAGATION_REQUIRED,-Exception");
        properties.setProperty("insert*", "PROPAGATION_REQUIRED,-Exception");
        properties.setProperty("create*", "PROPAGATION_REQUIRED,-Exception");
        properties.setProperty("persist*", "PROPAGATION_REQUIRED,-Exception");
        properties.setProperty("update*", "PROPAGATION_REQUIRED,-Exception");
        properties.setProperty("modify*", "PROPAGATION_REQUIRED,-Exception");
        properties.setProperty("merge*", "PROPAGATION_REQUIRED,-Exception");
        properties.setProperty("bind*", "PROPAGATION_REQUIRED,-Exception");
        properties.setProperty("del*", "PROPAGATION_REQUIRED,-Exception");
        properties.setProperty("drop*", "PROPAGATION_REQUIRED,-Exception");
        properties.setProperty("remove*", "PROPAGATION_REQUIRED,-Exception");
        properties.setProperty("reset*", "PROPAGATION_REQUIRED,-Exception");
        properties.setProperty("cancel*", "PROPAGATION_REQUIRED,-Exception");
        properties.setProperty("login*", "PROPAGATION_REQUIRED,-Exception");
        properties.setProperty("save*", "PROPAGATION_REQUIRED,-Exception");
        properties.setProperty("update*", "PROPAGATION_REQUIRED,-Exception");
        properties.setProperty("delete*", "PROPAGATION_REQUIRED,-Exception");
        properties.setProperty("*", "PROPAGATION_REQUIRED,-Exception,readOnly");
        TransactionInterceptor tsi = new TransactionInterceptor(transactionManager, properties);
        return tsi;
    }
    @Bean
    public BeanNameAutoProxyCreator txProxy() {
        BeanNameAutoProxyCreator creator = new BeanNameAutoProxyCreator();
        creator.setInterceptorNames("txAdvice");
        creator.setBeanNames("*Service","*Dao");
        creator.setProxyTargetClass(true);
        return creator;
    }
}

这个坑，踩了我很久，此解决方案，已同步更新到stackoverflow了
