Maven Mybatis JTA SprintBoot分布式事物管理，拦截器管理事物

如果要源码参考请访问：https://download.csdn.net/download/liqi\_q/10445505

java中分布式事物JTA是比较常用的第三方服务，下面我是使用的Atomikos ，分布式事物主要是2.5之前和之后使用上有明显的区别，Springboot项目在配置数据源的时候多数据源的情况下项目启动要指定一个默认的数据源及@Primary，2.5版本之前使用的时候如果说处理两个业务方法，方法一是@Primary数据源在前的话，方法二失败了他会回滚数据，反之，如果是方法二在前@Primary再后面的话，方法二的数据不会回滚。

下面我贴出来我的数据源的配置application.properties文件内容

配置文件要有对应的映射类和数据源配置

通过上面的配置之后就可使分布式事物了，分布式事物使用有两种方式，一种是在方法或者类上面添加注解的方式，另一种是配置拦截器的方式实现。

方式一：@Transactional

方式二：

@Bean(name = "txProAdvice")
        public TransactionInterceptor getProAdvisor(DataSourceProProperties dataSourceProProperties) throws Exception {
            DataSourceTransactionManager transactionManager = new DataSourceTransactionManager(dataSourcePro(dataSourceProProperties));
            Properties properties = new Properties();
            properties.setProperty("get*", "PROPAGATION_REQUIRED,-Exception,readOnly");
            properties.setProperty("add*", "PROPAGATION_REQUIRED");
            properties.setProperty("save*", "PROPAGATION_REQUIRED");
            properties.setProperty("insert*", "PROPAGATION_REQUIRED");
            properties.setProperty("update*", "PROPAGATION_REQUIRED");
            properties.setProperty("delete*", "PROPAGATION_REQUIRED");
            TransactionInterceptor tsi = new TransactionInterceptor(transactionManager,properties);
            return tsi;
        }
        @Bean
        public BeanNameAutoProxyCreator txProProxy() {
            BeanNameAutoProxyCreator creator = new BeanNameAutoProxyCreator();
            creator.setInterceptorNames("txProAdvice");
            creator.setBeanNames("*Service", "*ServiceImpl");
            creator.setProxyTargetClass(true);
            return creator;
        }

指定mybatis相关的配置分页插件和xml存放路径

@Bean(name = "sqlSessionFactoryPro")
    public SqlSessionFactory sqlSessionFactoryPro(@Qualifier("dataSourcePro") DataSource dataSource)throws Exception {
        SqlSessionFactoryBean bean = new SqlSessionFactoryBean();
        bean.setDataSource(dataSource);
        bean.setTypeAliasesPackage("com.boot.mvn.dev.entity");
        PathMatchingResourcePatternResolver resolver = new PathMatchingResourcePatternResolver();
        bean.setConfigLocation(resolver.getResource("classpath:mybatis-config.xml"));
        bean.setMapperLocations(resolver.getResources("classpath:/mappers/pro/*Mapper.xml"));
        return bean.getObject();
    }
