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...
