SPRING BOOT 环境下减少中间件依赖的UNIT测试

SPRING BOOT 环境下,测试有时会依赖于外部的中间件,如Mysql,Activemq,Mongodb等,那如何能减少这种依赖呢?
SPRING BOOT其实已经实现了自动化配置。

Mongodb

SPRING BOOT的自动化配置文件:org.springframework.boot.autoconfigure.mongo.embeddedEmbedded.MongoAutoConfiguration.java

www.0245.com_【官方首页】-澳门威尼斯在pom.xml中新增一test profile,并添加相应jar包,这样可防止对其他profile的影响,如果是在Eclipse跑测试,需在Project的属性中指定Active Profile为test,以覆盖pom.xml的定义。
www.0245.com_【官方首页】-澳门威尼斯这种方式即使是使用SPRING DATA MONGODB的REPOSITORY也是适用的。

    <profile>
        <id>test</id>
        <dependencies>
            <dependency>
                <groupId>de.flapdoodle.embed</groupId>
                <artifactId>de.flapdoodle.embed.mongo</artifactId>
                <scope>test</scope>
            </dependency>
        </dependencies>
        <activation>
            <activeByDefault>false</activeByDefault>
        </activation>
    </profile>
在application-test.yaml中添加端口,其他如IP那些信息都不需要
spring:
   data:
      mongodb:
         port: 27017

ActiveMQ

只需更改application-test.yml中的brokerUrl为vm://embedded即可
spring:
   activemq:
      broker-url: vm://embedded?broker.persistent=false,useShutdownHook=false
      in-memory: true
      non-blocking-redelivery: true
      #packages:
        #trust-all: false
        #trusted: com.memorynotfound
      pool:
        block-if-full: true
        block-if-full-timeout: -1
        create-connection-on-startup: true
        enabled: false
        expiry-timeout: 0
        idle-timeout: 30000
        max-connections: 1
        maximum-active-session-per-connection: 500
        reconnect-on-exception: true
        time-between-expiration-check: -1
        use-anonymous-producers: true
        user: admin
        #password: ENC(hWJHuMyhydTqyF32neasTw==)
        password: admin

关系型数据库

将在application-test.yml中的数据库信息删除,同时在pom.xml中添加jar包依赖,这边是采用HSQL数据库
    <profile>
        <id>test</id>
        <dependencies>
            <dependency>
                <groupId>org.hsqldb</groupId>
                <artifactId>hsqldb</artifactId>
                <scope>test</scope>
            </dependency>
        </dependencies>
        <activation>
            <activeByDefault>false</activeByDefault>
        </activation>
    </profile>
