springboot-配置多数据源之番外篇（分包实现）

场景：

随着业务发展，系统连接多数据库成为常态，继前面AOP的实现方式之后，这里记录一下分包实现的方式。

实现：

1.pom.xml

<?xml version="1.0" encoding="UTF-8"?>

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">

    <modelVersion>4.0.0</modelVersion>

    <parent>

        <groupId>com.mumu</groupId>

        <artifactId>springboot-mumu</artifactId>

        <version>1.0-SNAPSHOT</version>

    </parent>

    <artifactId>mumu-web</artifactId>

    <dependencies>

        <!-- web -->

        <dependency>

            <groupId>org.springframework.boot</groupId>

            <artifactId>spring-boot-starter-web</artifactId>

        </dependency>

        <!-- aop -->

        <dependency>

            <groupId>org.springframework.boot</groupId>

            <artifactId>spring-boot-starter-aop</artifactId>

        </dependency>

        <!-- mysql -->

        <dependency>

            <groupId>mysql</groupId>

            <artifactId>mysql-connector-java</artifactId>

            <scope>runtime</scope>

        </dependency>

        <!-- sqlserver -->

        <dependency>

            <groupId>com.microsoft.sqlserver</groupId>

            <artifactId>mssql-jdbc</artifactId>

            <scope>runtime</scope>

        </dependency>

        <!-- mybatis-plus -->

        <dependency>

            <groupId>com.baomidou</groupId>

            <artifactId>mybatis-plus-boot-starter</artifactId>

            <version>3.0.5</version>

        </dependency>

    </dependencies>

    <build>

        <plugins>

            <plugin>

                <groupId>org.springframework.boot</groupId>

                <artifactId>spring-boot-maven-plugin</artifactId>

            </plugin>

        </plugins>

    </build>

</project>

2.配置文件

server:

  port: 9587

spring:

  datasource:

    hikari:

      master:

        driverClassName: com.mysql.cj.jdbc.Driver

        jdbcUrl: jdbc:mysql://127.0.0.1:3306/boltloan?serverTimezone=GMT%2B8&useUnicode=true&characterEncoding=utf8

        username: root

        password: 123456

      slave:

        driverClassName: com.microsoft.sqlserver.jdbc.SQLServerDriver

        jdbcUrl: jdbc:sqlserver://127.0.0.1:1433;DatabaseName=TestDB

        username: SA

        password: <1234567890@Passw0rd>

#mybatis-plus

mybatis-plus:

  type-aliases-package: com.mumu.model

  mapper-locations: classpath:/mapper/**/*.xml

  configuration:

    jdbc-type-for-null: null

    map-underscore-to-camel-case: true

    cache-enabled: false

  global-config:

    db-config:

      id-type: auto

      field-strategy: not_empty

3.数据源配置类

采用注解的方式：每种数据源，使用一个对应注解！

敬请期待...
