2 基于Mybatis 方式

2.1 添加DatabaseIdProvider配置

package com.xs.dsy.config;

import org.apache.ibatis.mapping.DatabaseIdProvider;
import org.apache.ibatis.mapping.VendorDatabaseIdProvider;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import java.util.Properties;

/**
 * @Copyright (C), 2016-2023 MP
 * @ClassName: DsyDateSourceConfg
 * @Author: hf
 * @Date: 2023/4/24 15:50
 * @Description: 动态数据源Provider配置
 */
@Configuration
public class DsyDateSourceConfig {

    /**
     * 自动识别使用的数据库类型
     * 在mapper.xml中databaseId的值就是跟这里的value值对应,Key值必须是数据库供应商的标识ID，
     * 
     * 数据库标识ID名称: dataSource.getConnection().getMetaData().getDatabaseProductName();
     * 
     * 如果没有databaseId选择则说明该sql适用所有数据库
     */
    @Bean
    public DatabaseIdProvider getDatabaseIdProvider() {
        DatabaseIdProvider databaseIdProvider = new VendorDatabaseIdProvider();
        Properties properties = new Properties();
        properties.setProperty("Oracle", "oracle");
        properties.setProperty("MySQL", "mysql");
        properties.setProperty("PostgreSQL", "PostgreSQL");
        databaseIdProvider.setProperties(properties);
        return databaseIdProvider;
    }

}

2.2 在Mybatis的XML中,指定SQL语句的databaseId标签

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper
        PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.xs.dsy.ed.mapper.EdSysUserMapper">

    <!--MySQL数据库指定-->
    <select id="all" databaseId="mysql" resultType="com.xs.dsy.ed.domain.EdSysUser">
         SELECT * FROM ED_SYS_USER
    </select>

    <!--Oracle数据库指定-->
    <select id="all" databaseId="oracle" resultType="com.xs.dsy.ed.domain.EdSysUser">
         SELECT * FROM ed_sys_user
    </select>

    <!--PostgreSQL数据库指定-->
    <select id="all" databaseId="PostgreSQL" resultType="com.xs.dsy.ed.domain.EdSysUser">
         SELECT * FROM ed_sys_user
    </select>

</mapper>

2.3 控制器接口样例

package com.xs.dsy.ed.controller;

import com.xs.common.core.controller.BaseController;
import com.xs.common.core.domain.PageQuery;
import com.xs.common.core.domain.R;
import com.xs.common.core.page.TableDataInfo;
import com.xs.common.core.validate.AddGroup;
import com.xs.common.core.validate.EditGroup;
import com.xs.dsy.ed.domain.EdSysUser;
import com.xs.dsy.ed.domain.bo.EdSysUserBo;
import com.xs.dsy.ed.domain.vo.EdSysUserVo;
import com.xs.dsy.ed.service.EdSysUserService;
import lombok.RequiredArgsConstructor;
import org.springframework.validation.annotation.Validated;
import org.springframework.web.bind.annotation.*;

import javax.sql.DataSource;
import javax.validation.constraints.NotEmpty;
import javax.validation.constraints.NotNull;
import java.sql.Connection;
import java.sql.DatabaseMetaData;
import java.sql.SQLException;
import java.util.Arrays;
import java.util.HashMap;
import java.util.List;

/**
 * 用户信息-前端控制器
 *
 * @author Lion Li
 */
@Validated
@RequiredArgsConstructor
@RestController
@RequestMapping("/system/user")
public class EdSysUserController extends BaseController {

    private final EdSysUserService userService;

    private final DataSource dataSource;

    /**
     * 查询用户信息列表
     */
    @GetMapping("/queryAll")
    public R<Object> queryAll() throws SQLException {

        //1.0 获取数据源信息
        HashMap<String, Object> map = new HashMap<>();
        Connection connection = dataSource.getConnection();
        DatabaseMetaData metaData = connection.getMetaData();
        map.put("driverName", metaData.getDriverName());
        map.put("driverVersion", metaData.getDriverVersion());
        map.put("databaseProductName", metaData.getDatabaseProductName());
        map.put("databaseProductVersion", metaData.getDatabaseProductVersion());
        
        //2.0 查询数据
        List<EdSysUser> rows = userService.all();
        map.put("rows", rows);


        return R.ok(map);
    }
}

2.4 呈现效果

• 当项目配置的数据源是不同的数据库时,同一个接口会自动切换查询不同的数据库，从而只需注意部分语法兼容,不影响原有业务逻辑。
