若依ruoyi 动态多数据源配置（多种不同类型的数据库mysql，oracle，sqlite3，sqlserver等等）_若依连接oracle和mysql

我使用的是mybaits-plus，具体根据自己的情况做更改

增加其他数据库的配置 ，我这里是sqlite3与sqlserver

        <dependency>
            <groupId>org.xerial</groupId>
            <artifactId>sqlite-jdbc</artifactId>
            <version>3.36.0.3</version>
        </dependency>

        <dependency>
            <groupId>com.microsoft.sqlserver</groupId>
            <artifactId>mssql-jdbc</artifactId>
            <version>10.2.3.jre8</version>
        </dependency>

         <dependency>
            <groupId>com.baomidou</groupId>
            <artifactId>mybatis-plus-boot-starter</artifactId>
             <version>3.5.1</version>
        </dependency>

        <!-- 动态数据源 -->
        <dependency>
            <groupId>com.baomidou</groupId>
            <artifactId>dynamic-datasource-spring-boot-starter</artifactId>
            <version>3.5.2</version>
        </dependency>

    <!-- 阿里数据库连接池 -->
        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>druid-spring-boot-starter</artifactId>
            <version>1.2.16</version>
        </dependency>

在ruoyi-framework的中修改DruidProperties类与DruidConfig类

package com.ruoyi.framework.config.properties;

import lombok.Data;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Configuration;

/**

@Data
@Configuration
@ConfigurationProperties(prefix = "spring.datasource.dynamic.druid")
public class DruidProperties {

    private int initialSize;

    private int minIdle;

    private int maxActive;

    private int maxWait;

    private int connectTimeout;

    private int socketTimeout;

    private int timeBetweenEvictionRunsMillis;

    private int minEvictableIdleTimeMillis;

    private int maxEvictableIdleTimeMillis;

    private String validationQuery;

    private boolean testWhileIdle;

    private boolean testOnBorrow;

    private boolean testOnReturn;

    private StatViewServlet statViewServlet = new StatViewServlet();

    @Data
    public static class StatViewServlet {

        private String urlPattern;
        private String loginUsername;
        private String loginPassword;
