ruoyi(若依)配置多数据源(mysql+postgresql)，rouyi(Springboot)多数据源设置

一、除了MySQL驱动，我们还需要用到postgresql的驱动，所以我们先把驱动的依赖给导入进来

                           org.postgresql            postgresql        

二，修改application-druid.yml:

# 数据源配置spring:    datasource:        type: com.alibaba.druid.pool.DruidDataSource        druid:            # 主库数据源            master:                driverClassName: com.mysql.cj.jdbc.Driver                url: jdbc:mysql://localhost:3306/i_ren_shi?useUnicode=true&characterEncoding=utf8&zeroDateTimeBehavior=convertToNull&useSSL=true&serverTimezone=GMT%2B8                username: root                password: root            # 从库数据源            slave:                # 从数据源开关/默认关闭                enabled: true                driverClassName: org.postgresql.Driver                url: jdbc:postgresql://localhost:5432/easytrack                username: 123456                password: 123456            easytrack:                # 从数据源开关/默认关闭                enabled: true                driverClassName: org.postgresql.Driver                url: jdbc:postgresql://localhost:5432/easytrack                username: 123456                password: 123456

三、新数据源的配置

（1）修改DatasourceType

package com.ruoyi.common.enums;public enum DataSourceType{        MASTER,        SLAVE,        EASYTRACK}

（2）修改DruidConfig，这里有很多细节要注意，就是大小写的问题

  @Bean    @ConfigurationProperties("spring.datasource.druid.easytrack")    @ConditionalOnProperty(prefix = "spring.datasource.druid.easytrack", name = "enabled", havingValue = "true")    public DataSource easyTrackDataSource(DruidProperties druidProperties)    {        DruidDataSource dataSource = DruidDataSourceBuilder.create().build();        return druidProperties.dataSource(dataSource);    }    @Bean(name = "dynamicDataSource")    @Primary    public DynamicDataSource dataSource(DataSource masterDataSource)    {        Map targetDataSources = new HashMap<>();        targetDataSources.put(DataSourceType.MASTER.name(), masterDataSource);        setDataSource(targetDataSources, DataSourceType.SLAVE.name(), "slaveDataSource");        setDataSource(targetDataSources, DataSourceType.EASYTRACK.name(), "easyTrackDataSource");        return new DynamicDataSource(masterDataSource, targetDataSources);    }

（3）使用选择数据源，会自动切换数据源

@DataSource(value = DataSourceType.EASYTRACK)
