SpringBoot中双数据源的配置详解

前言申明

　　springBoot配置双数据源主要是配置类的书写和配置文件的书写，本文采用yml的形式进行配置，mapper和pojo两个个数据库都共用一个路径，dao层分开书写，各自配置文件中直接配置各自扫描路径即可。本文只讲解如何配置双数据源，如需配置单数据源的童鞋，可参看该链接：https://www.cnblogs.com/zblwyj/p/10668803.html

一、导入jar包

<dependency>
　　<groupId>org.mybatis.spring.boot</groupId>
　　<artifactId>mybatis-spring-boot-starter</artifactId>
　　<version>2.0.0</version>
</dependency

<dependency>
　　<groupId>com.alibaba</groupId>
　　<artifactId>druid</artifactId>
　　<version>1.1.9</version>
</dependency>
<!-- sqlite3驱动包 -->
<dependency>
　　<groupId>org.xerial</groupId>
　　<artifactId>sqlite-jdbc</artifactId>
</dependency>

二、书写配置文件View Code

# Tomcat
server:
    tomcat:
        uri-encoding: UTF-8
        max-threads: 1000
        min-spare-threads: 30
    port: 8088
#spring
spring:
    # 指定静态资源的路径
    resources:
        static-locations: classpath:/static/,classpath:/views/,file:${web.upload},file:${web.ueditorUpload}
# 数据源一
    datasource:
           master:
             jdbc-url: jdbc:sqlite:D:/java/xy.db
#        jdbc-url: jdbc:sqlite:/usr/java/myfile/xy.db
             driver-class-name: org.sqlite.JDBC
             username: 
             password:
#数据源二
           other:
             driver-class-name: org.sqlite.JDBC
# 方式一：  引用外部文件
             jdbc-url: jdbc:sqlite:D:/system.db
             username: 
             password:
      
                 
# Mybatis配置
#mybatis:
#    mapperLocations: classpath:mapper/**/*.xml
#    configLocation: classpath:/mybatis.xml
    
# sql打印
logging:
    level: debug
    level.com.xuanyin: debug
#    path: logs/
#    file: admin.log
