這篇文章主要介紹了SpringBoot中的多個事務管理詳解,事務管理是一種組織和協(xié)調(diào)各種活動和資源的方法,以實現(xiàn)特定目標,它涉及規(guī)劃、執(zhí)行和監(jiān)控各種任務,以確保項目或組織的順利運行,需要的朋友可以參考下

springboot多個事務管理

導入依賴

<!-- jta 管理多個數(shù)據(jù)源的事務-->
<dependency>
  <groupId>org.springframework.boot</groupId>
  <artifactId>spring-boot-starter-jta-atomikos</artifactId>
</dependency>

在application.properties配置文件中對兩個數(shù)據(jù)庫的配置內(nèi)容稍作修改。

mysql.datasource.test1.url = jdbc:mysql://localhost:3306/test1?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
# Mysql 2
mysql.datasource.test2.url =jdbc:mysql://localhost:3306/test2?useUnicode=true&characterEncoding=utf-8
mysql.datasource.test2.username =root
mysql.datasource.test2.password =123456
mysql.datasource.test2.minPoolSize = 3
mysql.datasource.test2.maxPoolSize = 25
mysql.datasource.test2.maxLifetime = 20000
mysql.datasource.test2.borrowConnectionTimeout = 30
mysql.datasource.test2.loginTimeout = 30
mysql.datasource.test2.maintenanceInterval = 60
mysql.datasource.test2.maxIdleTime = 60
mysql.datasource.test2.testQuery = select 1

在java文件夾下新建dbconfig包

里面分別寫兩個類和application.properties配置文件的信息相對應，配置文件中共配置了兩個數(shù)據(jù)源，那么dbconfig包中就需要寫兩個類，分別是DBconfig1和DBconfig2，下面省略了set和get方法。

@ConfigurationProperties("mysql.datasource.test1")
public class DBConfig1 {
    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;
}

@ConfigurationProperties("mysql.datasource.test2")
public class DBConfig2 {
    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;
}

在上篇文章中已經(jīng)配置了數(shù)據(jù)源的兩個配置類，這里需要修改一下。

@Configuration//注解到springboot容器中
@MapperScan(basePackages="com.gyf.test1.mapper",sqlSessionFactoryRef="test1SqlSessionFactory")
public class DataSource01 {

    // 配置數(shù)據(jù)源
    @Primary
    @Bean(name = "test1DataSource")
    public DataSource testDataSource(DBConfig1 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("test1DataSource");

        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 = "test1SqlSessionFactory")
    public SqlSessionFactory testSqlSessionFactory(@Qualifier("test1DataSource") DataSource dataSource)
            throws Exception {
        SqlSessionFactoryBean bean = new SqlSessionFactoryBean();
        bean.setDataSource(dataSource);
        return bean.getObject();
    }

    @Bean(name = "test1SqlSessionTemplate")
    public SqlSessionTemplate testSqlSessionTemplate(
            @Qualifier("test1SqlSessionFactory") SqlSessionFactory sqlSessionFactory) throws Exception {
        return new SqlSessionTemplate(sqlSessionFactory);
    }
}

@Configuration//注解到springboot容器中
@MapperScan(basePackages="com.gyf.test2.mapper",sqlSessionFactoryRef="test2SqlSessionFactory")
public class DataSource02 {

    // 配置數(shù)據(jù)源
    @Bean(name = "test2DataSource")
    public DataSource testDataSource(DBConfig2 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("test2DataSource");
        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 = "test2SqlSessionFactory")
    public SqlSessionFactory testSqlSessionFactory(@Qualifier("test2DataSource") DataSource dataSource)
            throws Exception {
        SqlSessionFactoryBean bean = new SqlSessionFactoryBean();
        bean.setDataSource(dataSource);
        return bean.getObject();
    }
    @Bean(name = "test2SqlSessionTemplate")
    public SqlSessionTemplate testSqlSessionTemplate(
            @Qualifier("test2SqlSessionFactory") SqlSessionFactory sqlSessionFactory) throws Exception {
        return new SqlSessionTemplate(sqlSessionFactory);
    }
}

啟動類加上注解配置

@EnableAutoConfiguration
//@ComponentScan(basePackages = {"com.gyf.dbconfig","com.gyf.datasource","com.gyf.web","com.gyf.test1.service","com.gyf.test2.service"})
@ComponentScan(basePackages = {"com.gyf"})
@EnableConfigurationProperties(value = {DBConfig1.class, DBConfig2.class})
public class App
{
    public static void main( String[] args )
    {
        //啟動springboot項目
        SpringApplication.run(App.class,args);
    }
}
