网上很多教程的配置比较老，并且不支持多数据源。踩坑后记录下，看了下MybatisPlus在github中提问非常不优化，文档也没有标注这块，只能看了下源码。
(1).首先需要加载MybatisPlus的多数据源组件，maven坐标如下
代码语言：javascript复制<dependency>
<groupId>com.baomidou</groupId>
<artifactId>dynamic-datasource-spring-boot-starter</artifactId>
<version>3.5.2</version>
</dependency>(2).配置多数据库src/main/resources/application.yml
代码语言：javascript复制spring:
datasource:
dynamic:
primary: ds1 #设置默认的数据源或者数据源组,默认值即为master
strict: false #严格匹配数据源,默认false. true未匹配到指定数据源时抛异常,false使用默认数据源
datasource:
ds1: # X2会员档案
url: jdbc:oracle:thin:@152.80.196.29:1523:orcl
username: a_gls_10247622
password: 123456
driver-class-name: oracle.jdbc.driver.OracleDriver
ds2: # Erp数据库
url: jdbc:mysql://181.179.241.251:3309/ellassay_erp
username: gaojiufeng
password: 123456
driver-class-name: com.mysql.cj.jdbc.Driver
mybatis-plus:
mapper-locations: classpath:mapper/*.xml
configuration:
map-underscore-to-camel-case: false(3).分页组件配置src/main/java/com/ellassay/x2/sync/config/MybatisPlusConfig.java
代码语言：javascript复制package com.ellassay.x2.sync.config;
import com.baomidou.mybatisplus.extension.plugins.MybatisPlusInterceptor;
import com.baomidou.mybatisplus.extension.plugins.inner.PaginationInnerInterceptor;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
@Configuration
public class MybatisPlusConfig {
@Bean
public MybatisPlusInterceptor mybatisPlusInterceptor() {
MybatisPlusInterceptor interceptor = new MybatisPlusInterceptor();
interceptor.addInnerInterceptor(new PaginationInnerInterceptor());
return interceptor;
}
}切记此处不需要设置DB_TYPE，切记此处不需要设置DB_TYPE，切记此处不需要设置DB_TYPE！！！
(4).查询代码如下：
代码语言：javascript复制// 分页设置
Page<X2UserEntity> x2Page = new Page<>(i, pageSize);
// 查询分页结果
Page<X2UserEntity> x2UserPage = x2UserMapper.selectPage(x2Page, queryWrapper);
List<X2UserEntity> x2UserList = x2UserPage.getRecords();xml文件如下：
代码语言：javascript复制<?xml version="1.0" encoding="UTF-8"?>
