Gradle项目之Spring.profile.开发.测试.生产环境的配置和切换之一键部署

背景：

软件开发过程一般涉及“开发 -> 测试 -> 部署上线”多个阶段，每个阶段的环境的配置参数会有不同，如数据源，文件路径等。为避免每次切换环境时都要进行参数配置等繁琐的操作，可以通过spring的profile功能来进行配置参数的切换。

部署阶段最原始的方式是连接服务器，停掉tomcat，备份之前的war，替换war，启动tomcat，这个过程不繁复，但是一天来两次也是够烦的了。

环境配置：

jdk8，gradle3.2，IntelliJ IDEA，tomcat8。

1：springprofile

1：建立文件夹environment，里面放着三个不同环境的配置文件

2：在配置文件中配置profile-beans。注意：需要放在最下面，并且，所有的配置文件都需要加上profile-beans，不然会失效，切记切记。

</bean>

<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.jniu.*.dao" />
<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" />

</bean>

<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com/jniu/*/dao/mapper/*"/>
</bean>

<!-- 使用annotation注解方式配置事务 -->
<tx:annotation-driven transaction-manager="transactionManager" />

<beans profile="dev">

</beans>
<beans profile="pro">
<context:property-placeholder ignore-resource-not-found="true" location="classpath:environment/pro_xyfapp.properties"/>
</beans>
</beans>

3：通过设置spring.profiles.default和spring.profiles.active这两个属性来激活和使用对应的配置文件。
设置方式有多种：
在web.xml中作为web应用的上下文参数context-param；

在web.xml中作为DispatcherServlet的初始化参数；

作为JNDI条目；

作为环境变量；

作为JVM的系统属性；

在集成测试类上，使用@ActiveProfiles注解配置。

如果在程序中也使用到了spring.profiles.active，可以按照以下代码获取web.xml中的value值：

import javax.servlet.ServletContext;
import org.springframework.web.context.WebApplicationContext;

public class WebContextListener extends org.springframework.web.context.ContextLoaderListener{
public WebApplicationContext initWebApplicationContext(ServletContext servletContext) {
String env = servletContext.getInitParameter("spring.profiles.active");
//env可以设置在缓存中，供项目使用
return super.initWebApplicationContext(servletContext);
}
}

2：使用gradle进行一键部署（该步骤全部都是修改gradle配置文件）

1：安装插件 apply plugin: 'war'
2：设置remotes
remotes {

    deployServer_test {

        host = '1.1.1.1'

        user = 'root'

        password = 'password'

    }

    deployServer_pro {

        host = '2.2.2.2'

        user = 'root'

        password = 'password'

    }

}
3：编写shell命令，这段配置就不写了，最会下面贴出整个gradle文件
4：最后，打开idea的Terminal面板，该面板默认就是项目根目录，输入gradle clean war deploy_test回车即可

apply plugin: 'org.hidetake.ssh'
apply plugin: 'war'
apply plugin: 'java'
apply plugin: 'idea'
