SpringBoot2.0+與Mybatis-puls整合多數據源（dynamic-datasource-spring-boot-starter）
寫在前面
在我們的項目中不可避免有時候和第三方對接中需要接入多數據源，一般來講我們大多數是採用AOP方式去動態的調整數據源，也有通過Druid去配置主從數據源的，本篇文章主要介紹多個數據源分開使用的情況，我們採用的苞米豆團隊的dynamic-datasource-spring-boot-starter 去實現多數據源
代碼實現部分如下
首先貼出我們的entity，Service，
UserEntity
package org.wuyd.testdockgame.entity;
import com.baomidou.mybatisplus.annotation.TableId;
import com.baomidou.mybatisplus.annotation.TableName;
import lombok.Builder;
import lombok.Data;
import java.io.Serializable;
/**
* @author wuyd
* 2019/7/11 10:33
*/
@Data
@Builder
@TableName("user")
public class UserEntity implements Serializable {
@TableId("id")
private Integer id;
private String age;
private String name;
private String password;
private String sex;
}
UserMapper
package org.wuyd.testdockgame.mapper;
import com.baomidou.mybatisplus.core.mapper.BaseMapper;
import org.apache.ibatis.annotations.Mapper;
import org.wuyd.testdockgame.entity.UserEntity;
/**
* @author wuyd
* 2019/7/11 10:40
*/
@Mapper
public interface UserMapper extends BaseMapper<UserEntity> {
}
UserService
package org.wuyd.testdockgame.service;
import com.baomidou.mybatisplus.extension.service.IService;
import org.wuyd.testdockgame.entity.UserEntity;
/**
* @author wuyd
* 2019/7/11 10:42
*/
public interface UserService extends IService<UserEntity> {
}
兩個實現類，不同數據源的UserServiceImpl
package org.wuyd.testdockgame.service.impl;
import com.baomidou.dynamic.datasource.annotation.DS;
import com.baomidou.mybatisplus.extension.service.impl.ServiceImpl;
import org.springframework.stereotype.Service;
import org.wuyd.testdockgame.entity.UserEntity;
import org.wuyd.testdockgame.mapper.UserMapper;
import org.wuyd.testdockgame.service.UserService;
/**
* @author wuyd
* 2019/7/11 10:43
*/
@Service("userService1")
public class UserService1Impl extends ServiceImpl<UserMapper, UserEntity> implements UserService {
}
package org.wuyd.testdockgame.service.impl;
import com.baomidou.dynamic.datasource.annotation.DS;
import com.baomidou.mybatisplus.extension.service.impl.ServiceImpl;
import org.springframework.stereotype.Service;
import org.wuyd.testdockgame.entity.UserEntity;
import org.wuyd.testdockgame.mapper.UserMapper;
import org.wuyd.testdockgame.service.UserService;
/**
* @author wuyd
* 2019/7/11 10:43
*/
@DS("db2")
@Service("userService2")
public class UserService2Impl extends ServiceImpl<UserMapper, UserEntity> implements UserService {
}
