第一步添加atomikos的依赖
第二步配置数据源，我这里有2个数据库(ruan和youxianqi)，你有多少就加多少。
spring: datasource: system: jdbc-url: jdbc:oracle:thin:@localhost:1521/orcl driver-class-name: oracle.jdbc.OracleDriver username: yuan password: 1234 initial-size: 5 min-idle: 5 max-active: 20 min-evictable-idle-time-millis: 300000 validation-query: SELECT 1 FROM DUAL test-while-idle: true kllogt: jdbc-url: jdbc:oracle:thin:@localhost:1521/orcl driver-class-name: oracle.jdbc.OracleDriver username: youxianqi password: youxianqi initial-size: 5 min-idle: 5 max-active: 20 min-evictable-idle-time-millis: 300000 validation-query: SELECT 1 FROM DUAL test-while-idle: truelogging: level: org.springframework.web: debug
然后创建DBConfig1和DBConfig2，这两个实体类就是存放两个数据源的数据的。
package com.cgb.config; import org.springframework.boot.context.properties.ConfigurationProperties; @ConfigurationProperties(prefix = "spring.datasource.system")public class DBConfig1 { private String jdbc-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 getJdbc-url() { return url; } public void setJdbc-url(String jdbc-url) { this.jdbc-url= jdbc-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; } }
然后创建两个数据源RuanMyBatisConfig和YouMyBatisConfig，注意@Primary注解只能有一个。
package com.cgb.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.context.annotation.Bean;import org.springframework.context.annotation.Configuration;import org.springframework.context.annotation.Primary;import com.atomikos.jdbc.AtomikosDataSourceBean;import com.cgb.config.DBConfig1;import com.MySQL.jdbc.jdbc2.optional.MysqlXADataSource; @Configuration@MapperScan(basePackages = "com.cgb.ruan", sqlSessionTemplateRef = "testSqlSessionTemplate")public class RuanMyBatisConfig { // 配置数据源 @Primary @Bean(name = "dataSource1") 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("dataSource1"); 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("dataSource1") 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); }}
