最近的项目使用多数据源，于是想起之前mybatis-plus系列的dynamic-datasource-springboot-starter 由于springboot2.x使用hikari作为默认数据库连接池，就是用springboot2.X+mybatis-plus3.x+dynamic-datasource-springboot-starter3.0.0进行了集成，代码如下 MybatisConfiguration.java
package com.share.config;
import com.baomidou.mybatisplus.extension.plugins.PaginationInterceptor;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
@Configuration
public class MybatisConfiguration {
/**
* 分页插件注册
* @return
*/
@Bean
public PaginationInterceptor paginationInterceptor() {
return new PaginationInterceptor();
}
}BaseEntity.java

import com.baomidou.mybatisplus.annotation.TableField;
import com.baomidou.mybatisplus.annotation.TableId;

import java.util.Date;
@Data
public class BaseEntity implements Serializable {
private static final long serialVersionUID = 5741450406019549099L;
@TableId(type = IdType.AUTO)
private Long id;
@TableField(value = "create_time")
private Date createTime;
@TableField(value = "update_time")
private Date updateTime;
@TableField(value = "delete_time")
private Date deleteTime;
}User.java
