@(springboot多个事务管理)
参考上篇文章配置多数据源
Springboot使用jta管理多个事务。
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);
}
}
