SpringBoot事务管理入门

一.SpringBoot整合事务管理。

SpringBoot整合事务管理只需要在主要方法上加@Transition注解即可。

二.SpringBoot分布式事务管理。

配置数据源文件：

# Mysql 1
mysql.datasource.test.url = jdbc:mysql://localhost:3306/test?serverTimezone=GMT%2B8&useUnicode=true&characterEncoding=utf-8
mysql.datasource.test.username = root
mysql.datasource.test.password = 123456

mysql.datasource.test.minPoolSize = 3
mysql.datasource.test.maxPoolSize = 25
mysql.datasource.test.maxLifetime = 20000
mysql.datasource.test.borrowConnectionTimeout = 30
mysql.datasource.test.loginTimeout = 30
mysql.datasource.test.maintenanceInterval = 60
mysql.datasource.test.maxIdleTime = 60
mysql.datasource.test.testQuery = select 1


# Mysql 2
mysql.datasource.test1.url =jdbc:mysql://localhost:3306/test1?serverTimezone=GMT%2B8&useUnicode=true&characterEncoding=utf-8
mysql.datasource.test1.username =root
mysql.datasource.test1.password =123456

mysql.datasource.test1.minPoolSize = 3
mysql.datasource.test1.maxPoolSize = 25
mysql.datasource.test1.maxLifetime = 20000
mysql.datasource.test1.borrowConnectionTimeout = 30
mysql.datasource.test1.loginTimeout = 30
mysql.datasource.test1.maintenanceInterval = 60
mysql.datasource.test1.maxIdleTime = 60
mysql.datasource.test1.testQuery = select 1

配置数据库连接：

@ConfigurationProperties(prefix = "mysql.datasource.test")
public class DbConfig {
    private String url;
    private String username;
    private String password;
    private int minPoolSize;
    private int maxPoolSize;
    private int maxLifetime;
    private int borrowConnectionTimeout;
    private int loginTimeout;
    private int maintenanceInterval;
    private int maxIdleTime;
    private String testQuery;

省略set、get.....

public class TestConfig {

    public DataSource testDataSource(DbConfig testConfig) throws SQLException {
        MysqlXADataSource mysqlXaDataSource = new MysqlXADataSource();
        mysqlXaDataSource.setUrl(testConfig.getUrl());
        mysqlXaDataSource.setPinGlobalTxToPhysicalConnection(true);
        mysqlXaDataSource.setPassword(testConfig.getPassword());
        mysqlXaDataSource.setUser(testConfig.getUsername());
        mysqlXaDataSource.setPinGlobalTxToPhysicalConnection(true);

        AtomikosDataSourceBean xaDataSource = new AtomikosDataSourceBean();
        xaDataSource.setXaDataSource(mysqlXaDataSource);
        xaDataSource.setUniqueResourceName("testDataSource");

        xaDataSource.setMinPoolSize(testConfig.getMinPoolSize());
        xaDataSource.setMaxPoolSize(testConfig.getMaxPoolSize());
        xaDataSource.setMaxLifetime(testConfig.getMaxLifetime());
        xaDataSource.setBorrowConnectionTimeout(testConfig.getBorrowConnectionTimeout());
        xaDataSource.setLoginTimeout(testConfig.getLoginTimeout());
        xaDataSource.setMaintenanceInterval(testConfig.getMaintenanceInterval());
        xaDataSource.setMaxIdleTime(testConfig.getMaxIdleTime());
        xaDataSource.setTestQuery(testConfig.getTestQuery());
        return xaDataSource;
    }

    @Bean(name = "testSqlSessionFactory")
    public SqlSessionFactory testSqlSessionFactory(@Qualifier("testDataSource") DataSource dataSource)
            throws Exception {
        SqlSessionFactoryBean bean = new SqlSessionFactoryBean();
        bean.setDataSource(dataSource);
        return bean.getObject();
    }

    @Bean(name = "testSqlSessionTemplate")
    public SqlSessionTemplate testSqlSessionTemplate(
            @Qualifier("testSqlSessionFactory") SqlSessionFactory sqlSessionFactory) throws Exception {
        return new SqlSessionTemplate(sqlSessionFactory);
    }

}

service：

controller：

运行结果：

控制台：

加载atomikos信息。 

 运行结果报错，并且数据库1、2都未添加数据，说明事务回滚了。
