SpringBoot結合Druid配置JNDI多數據源

Tomcat配置JNDI（%TOMCAT_HOME%/conf/context.xml）

<!-- 主庫 -->

master配置

@Configuration

public class MasterBaseDataSourceConfig {

    @Value("${db.datasource.jndiName.masterDB}")
    private String jndiName;

    }

    @Primary
    @Bean(name = "masterTransactionManager")

            throws Exception {

    }
}

cluster配置

public class ClusterBaseDataSourceConfig {

    @Value("${db.datasource.jndiName.clusterDB}")
    private String jndiName;

    }

    @Bean(name = "clusterTransactionManager")

        return new DataSourceTransactionManager(clusterDataSource());
    }

    @Bean(name = "clusterSqlSessionFactory")
    public SqlSessionFactory clusterSqlSessionFactory(@Qualifier("clusterDataSource") DataSource clusterDataSource)
