本文详细介绍了如何在Spring Boot项目中使用Atomikos实现跨数据源的分布式事务管理，包括引用jta-atomikos依赖、配置多数据源、整合MyBatis以及在Service层使用注解实现事务控制。

1.引用jta-atomikos架包

<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-jta-atomikos</artifactId>
</dependency>

2,首先配置数据源，因为是要演示分布式事务管理所以要配置多个数据源（2个）

# Mysql 1
mysql.datasource.test1.url = jdbc:mysql://localhost:3306/test01?useUnicode=true&characterEncoding=utf-8
mysql.datasource.test1.username = root
mysql.datasource.test1.password = root
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/test02?useUnicode=true&characterEncoding=utf-8
mysql.datasource.test2.username =root
mysql.datasource.test2.password =root
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

3，配置读取数据库属性文件

DBConfig1.java

package com.itmayiedu.config;
import org.springframework.boot.context.properties.ConfigurationProperties;
@ConfigurationProperties(prefix = "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;
public String getUrl() {
return url;
}
public void setUrl(String url) {
this.url = url;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public int getMinPoolSize() {
return minPoolSize;
}
public void setMinPoolSize(int minPoolSize) {
this.minPoolSize = minPoolSize;
}
public int getMaxPoolSize() {
return maxPoolSize;
}
public void setMaxPoolSize(int maxPoolSize) {
this.maxPoolSize = maxPoolSize;
}
public int getMaxLifetime() {
return maxLifetime;
}
public void setMaxLifetime(int maxLifetime) {
this.maxLifetime = maxLifetime;
}
public int getBorrowConnectionTimeout() {
return borrowConnectionTimeout;
}
public void setBorrowConnectionTimeout(int borrowConnectionTimeout) {
this.borrowConnectionTimeout = borrowConnectionTimeout;
}
public int getLoginTimeout() {
return loginTimeout;
}
public void setLoginTimeout(int loginTimeout) {
this.loginTimeout = loginTimeout;
}
public int getMaintenanceInterval() {
return maintenanceInterval;
}
public void setMaintenanceInterval(int maintenanceInterval) {
this.maintenanceInterval = maintenanceInterval;
}
public int getMaxIdleTime() {
return maxIdleTime;
}
public void setMaxIdleTime(int maxIdleTime) {
this.maxIdleTime = maxIdleTime;
}
public String getTestQuery() {
return testQuery;
}
public void setTestQuery(String testQuery) {
this.testQuery = testQuery;
}
}

DBConfig2.java

package com.itmayiedu.config;
import org.springframework.boot.context.properties.ConfigurationProperties;
@ConfigurationProperties(prefix = "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;
public String getUrl() {
return url;
}
public void setUrl(String url) {
this.url = url;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public int getMinPoolSize() {
return minPoolSize;
}
public void setMinPoolSize(int minPoolSize) {
this.minPoolSize = minPoolSize;
}
public int getMaxPoolSize() {
return maxPoolSize;
}
public void setMaxPoolSize(int maxPoolSize) {
this.maxPoolSize = maxPoolSize;
}
public int getMaxLifetime() {
return maxLifetime;
}
public void setMaxLifetime(int maxLifetime) {
this.maxLifetime = maxLifetime;
}
public int getBorrowConnectionTimeout() {
return borrowConnectionTimeout;
}
public void setBorrowConnectionTimeout(int borrowConnectionTimeout) {
this.borrowConnectionTimeout = borrowConnectionTimeout;
}
public int getLoginTimeout() {
return loginTimeout;
}
public void setLoginTimeout(int loginTimeout) {
this.loginTimeout = loginTimeout;
}
public int getMaintenanceInterval() {
return maintenanceInterval;
}
public void setMaintenanceInterval(int maintenanceInterval) {
this.maintenanceInterval = maintenanceInterval;
}
public int getMaxIdleTime() {
return maxIdleTime;
}
public void setMaxIdleTime(int maxIdleTime) {
this.maxIdleTime = maxIdleTime;
}
public String getTestQuery() {
return testQuery;
}
public void setTestQuery(String testQuery) {
this.testQuery = testQuery;
}
}

4,配置TestMyBatisConfig1，TestMyBatisConfig2，将两个数据源放入atomikos进行一个管理

TestMyBatisConfig1

package com.itmayiedu.datasource;
import java.sql.SQLException;
import javax.sql.DataSource;
import org.apache.ibatis.session.SqlSessionFactory;
import org.mybatis.spring.SqlSessionFactoryBean;
import org.mybatis.spring.SqlSessionTemplate;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.boot.jta.atomikos.AtomikosDataSourceBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Primary;
import com.itmayiedu.config.DBConfig1;
import com.mysql.jdbc.jdbc2.optional.MysqlXADataSource;
@Configuration
@MapperScan(basePackages = "com.itmayiedu.test01", sqlSessionTemplateRef = "testSqlSessionTemplate")
public class TestMyBatisConfig1 {
// 配置数据源
@Primary
@Bean(name = "testDataSource")
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("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;
}
@Primary
@Bean(name = "testSqlSessionFactory")
public SqlSessionFactory testSqlSessionFactory(@Qualifier("testDataSource") DataSource dataSource)
throws Exception {
SqlSessionFactoryBean bean = new SqlSessionFactoryBean();
bean.setDataSource(dataSource);
return bean.getObject();
}
@Primary
@Bean(name = "testSqlSessionTemplate")
public SqlSessionTemplate testSqlSessionTemplate(
@Qualifier("testSqlSessionFactory") SqlSessionFactory sqlSessionFactory) throws Exception {
return new SqlSessionTemplate(sqlSessionFactory);
}
}

TestMyBatisConfig2

package com.itmayiedu.datasource;
import java.sql.SQLException;

import org.apache.ibatis.session.SqlSessionFactory;
import org.mybatis.spring.SqlSessionFactoryBean;
import org.mybatis.spring.SqlSessionTemplate;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.boot.jta.atomikos.AtomikosDataSourceBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import com.itmayiedu.config.DBConfig1;
import com.itmayiedu.config.DBConfig2;
import com.mysql.jdbc.jdbc2.optional.MysqlXADataSource;
@Configuration
//basePackages 最好分开配置如果放在同一个文件夹可能会报错
@MapperScan(basePackages = "com.itmayiedu.test02", sqlSessionTemplateRef = "testSqlSessionTemplate2")
public class TestMyBatisConfig2 {
// 配置数据源
@Bean(name = "testDataSource2")
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("testDataSource2");
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 = "testSqlSessionFactory2")
public SqlSessionFactory testSqlSessionFactory(@Qualifier("testDataSource2") DataSource dataSource)
throws Exception {
SqlSessionFactoryBean bean = new SqlSessionFactoryBean();
bean.setDataSource(dataSource);
return bean.getObject();
}
@Bean(name = "testSqlSessionTemplate2")
public SqlSessionTemplate testSqlSessionTemplate(
@Qualifier("testSqlSessionFactory2") SqlSessionFactory sqlSessionFactory) throws Exception {
return new SqlSessionTemplate(sqlSessionFactory);
}
}
