SpringBoot中的多个事务管理详解
作者：刻苦的樊同学
这篇文章主要介绍了SpringBoot中的多个事务管理详解,事务管理是一种组织和协调各种活动和资源的方法,以实现特定目标,它涉及规划、执行和监控各种任务,以确保项目或组织的顺利运行,需要的朋友可以参考下
springboot多个事务管理
导入依赖
<!-- jta 管理多个数据源的事务--> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-jta-atomikos</artifactId> </dependency>
在application.properties配置文件中对两个数据库的配置内容稍作修改。
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文件夹下新建dbconfig包
里面分别写两个类和application.properties配置文件的信息相对应，配置文件中共配置了两个数据源，那么dbconfig包中就需要写两个类，分别是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;
}
在上篇文章中已经配置了数据源的两个配置类，这里需要修改一下。
@Configuration//注解到springboot容器中
@MapperScan(basePackages="com.gyf.test1.mapper",sqlSessionFactoryRef="test1SqlSessionFactory")
public class DataSource01 {
// 配置数据源
@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 {
// 配置数据源
@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);
}
}
启动类加上注解配置
@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 )
{
//启动springboot项目
SpringApplication.run(App.class,args);
}
}
