spring boot,spring data jpa同一事务内修改不可见

目前我遇到这么个问题,在同一事务内,先saveAndFlush()了一条数据,在同一方法内,事务最终提交前,然后立刻查询此数据,但是并查不到。但是据我多年经验,同一事务内,尽管没提交,但是其修改在同一的当前的事务内应该是可见的才对呀。

困惑很久了,什么各种事务隔离性都试了,况且所谓事务隔离性,都是指不同事务间,我这是同一事务内都不可见,求求大侠们帮忙看看, 实在找不到解决思路了。谢谢大家,哎,没有C币,只能乞求大家了。

详细的代码和过程,我已经发在stackoverflow了,链接如下:

2个回答

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。

zwllxs 可是我就一个库哦,没有读写分离,我觉得肯定哪里配置或依赖有啥问题,实在找不出来了
一年多之前 回复

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");

        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

Spring boot + Spring Data JPA + Hibernate缓存问题
如题,项目框架为Spring boot + Spring Data JPA + Hibernate,hibernate中有Query.list()和query.iterator()方法,其中query.iterator()方法去查询时会用到缓存,返回的参数类型是Iterator,如果使用Spring Data JPA+hibernate如何实现查询一个list使用到缓存呢,JPA中的PagingAndSortingRepository接口中的findAll()方法返回的Iterator类型好像和query.iterator()的效果不一样,哪个哥们可以解答下,万分感激!

关于spring data jpa的问题.
spring boot 中通过爬虫爬取内容(中文),然后在mysql中插入数据。 我在本地测试是没问题的,一共13条数据都能采集并保存。但是我部署到云服务器的时候,只能保存11条数据; 我的save函数思路是这样的,如果数据库里没有该数据则插入数据到表中。 ```java if((gradeRepository.findByCourseName(grade.getCourseName()))==null){ 保存数据 } ``` 经过打印调试,发现少了的那两条记录的if的结果是false,也就是一开始数据库没有数据的情况下find返回的结果不为空……请问可能是什么原因?谢谢! 系统环境:腾讯云 Centos7.3, Mysql 5.6, Spring boot 1.5.6.RELEASE ![图片说明](https://img-ask.csdn.net/upload/201708/21/1503316702_263211.png)
spring boot中找不到jsp
查了一天了也没查到问题,我配置了mvc的前缀和后缀,可就是返回不了jsp,是打的war包有问题吗, 还是缺少什么web的包,它只会报Circular view path [/main]: would dispatch back to the current handler URL [/main] again. Check your ViewResolver setup! (Hint: This may be the result of an unspecified view, due to default view name generation.),实在是查不到怎么解决了,照着springboot的官方web例子改也不行,直接返回了字符串而不是jsp页面,真心求各位帮帮忙。 yml配置文件里的源码 ``` mvc: view: prefix: /WEB-INF/jsp/ suffix: .jsp ``` gradle的依赖包引入 ``` compile 'org.springframework.boot:spring-boot-starter-data-jpa' compile 'org.springframework.boot:spring-boot-starter-freemarker' compile 'org.springframework.boot:spring-boot-starter-groovy-templates' compile 'org.springframework.boot:spring-boot-starter-jdbc' compile 'com.h2database:h2:1.4.190' compile 'com.alibaba:fastjson:1.2.7' compile 'com.google.guava:guava:18.0' compile 'org.springframework.boot:spring-boot-starter-redis' compile 'org.springframework.boot:spring-boot-starter-web' // compile 'org.springframework.boot:spring-boot-starter-jetty' compile 'org.springframework.boot:spring-boot-starter-tomcat' compile 'org.apache.tomcat.embed:tomcat-embed-jasper' compile 'javax.servlet:jstl' compile 'org.apache.directory.studio:org.apache.commons.lang:2.6' compile 'commons-io:commons-io:2.4' compile 'mysql:mysql-connector-java' testCompile 'org.springframework.boot:spring-boot-starter-test' compile 'org.springframework.boot:spring-boot-starter-data-rest' compile 'org.springframework.boot:spring-boot-configuration-processor' compile 'com.googlecode.xmemcached:xmemcached:2.0.0' ``` controller ``` @RequestMapping("/main") public ModelAndView welcome1() { logger.error("111111111111111") return new ModelAndView("/main") } ``` 日志能打出来,但是这个main.jsp找不到 war包的目录结构 ![图片说明](https://img-ask.csdn.net/upload/201604/27/1461742939_597620.png) 又去查了一下,视频和例子都在说引入 compile 'org.springframework.boot:spring-boot-starter-tomcat' compile 'org.apache.tomcat.embed:tomcat-embed-jasper' 两个依赖后,注释为@Controller,直接return字符串类型的jsp名就可以 可就是还是不行,ViewResolver好像没有设置

Spring boot 多表关联问题
有这样两张表,新闻表news、新闻追踪表tarcing_news(记录访问量) CREATE TABLE `news` ( `news_id` int(11) NOT NULL AUTO_INCREMENT, `title` varchar(255) NOT NULL, `content` text NOT NULL, PRIMARY KEY (`news_id`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8; CREATE TABLE `tracing_news` ( `tracing_id` int(11) NOT NULL AUTO_INCREMENT, `news_id` int(11) NOT NULL, PRIMARY KEY (`tracing_id`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8; 现使用spring data jpa实现查询新闻内容和其对应的阅读量,sql文如下: SELECT n.*, tt.count FROM news n, (SELECT t.news_id,COUNT(1) AS 'count' FROM tracing_news t GROUP BY news_id) tt WHERE n.news_id = tt.news_id 请问,如果是这样,实体和repository应该怎么写?

@EnableTransactionManagement开启事务注解驱动
> Spring Boot 使用事务非常简单,首先使用注解 @EnableTransactionManagement 开启事务支持后,然后在访问数据库的Service方法上添加注解 @Transactional 便可。 > > 关于事务管理器,不管是JPA还是JDBC等都实现自接口 PlatformTransactionManager 如果你添加的是 spring-boot-starter-jdbc 依赖,框架会默认注入 DataSourceTransactionManager 实例。如果你添加的是 spring-boot-starter-data-jpa 依赖,框架会默认注入 JpaTransactionManager 实例。 这是其他博主给的结论,但是为什么我用了@EnableTransactionManagement注解,运行时,却报错“ No qualifying bean of type 'org.springframework.transaction.PlatformTransactionManager' available”,需要我手动注入TransactionManager,不是说会自动注入的嘛? ![图片说明](https://img-ask.csdn.net/upload/201907/11/1562807775_812625.png)

Python爬虫精简步骤1 获取数据
爬虫的工作分为四步: 1.获取数据。爬虫程序会根据我们提供的网址,向服务器发起请求,然后返回数据。 2.解析数据。爬虫程序会把服务器返回的数据解析成我们能读懂的格式。 3.提取数据。爬虫程序再从中提取出我们需要的数据。 4.储存数据。爬虫程序把这些有用的数据保存起来,便于你日后的使用和分析。 这一篇的内容就是:获取数据。 首先,我们将会利用一个强大的库——requests来获取数据。 在电脑上安装
