共享配置资源

引言

最近一个项目要做私有化，本身配置这一块，用的是配置中心，现在要兼容私有化和公有化的部署方式。考虑到避免针对不同的部署方式，维护两套代码，计划配置模块化。私有话对用私有化的本地配置，公有化对应公有化的配置中。通过共享配置的模式，模块化配置，支持可插拔。

配置模块

在引言中描述的背景下，将模块查分出来，测试的时候发现除了问题，根本不起作用，网上搜了一番，多少多环境的配置，比如针对开发，测试，预发，生成环境(dev，test， exp，prod)的配置分离，查到了共享配置是通过解压jar包方式，姿势不对，放弃了，感觉不考虑。使用英文Google一下，找到答案，论英语的重要性。一个资源绑定的插件maven-remote-resources-plugin，具体连接见附件。从此可以看出，认知范围，直接影响你的思想及行为。

废话，少说，操作起来

在共享配置模块ananas-config中添加如下插件

 <plugin>
                <artifactId>maven-remote-resources-plugin</artifactId>
                <version>1.7.0</version>
                <executions>
                    <execution>
                        <goals>
                            <goal>bundle</goal>
                        </goals>
                    </execution>
                </executions>
                <configuration>
                    <includes>
                        <include>**/properties/*.properties</include>
                        <include>**/conf/*.properties</include>
                        <include>**/conf/*.xml</include>
                        <include>**/*.yml</include>
                        <include>**/*.xml</include>
                    </includes>
                </configuration>
            </plugin>

在ananas-web模块中引用共享配置模块，同时添加maven-remote-resources-plugin插件

<dependency>
			<groupId>com.homestory</groupId>
			<artifactId>ananas-config</artifactId>
			<version>${ananas.config.version}</version>
</dependency>

...
<!--引用远程共享资源-->
<plugin>
	<groupId>org.apache.maven.plugins</groupId>
	<artifactId>maven-remote-resources-plugin</artifactId>
	<version>1.7.0</version>
	<configuration>
		<resourceBundles>
			<resourceBundle>com.homestory:ananas-config:${ananas.config.version}</resourceBundle>
		</resourceBundles>
	</configuration>
	<executions>
		<execution>
			<goals>
				<goal>process</goal>
			</goals>
		</execution>
	</executions>
</plugin>

 classpath和classpath的区别](https://www.jianshu.com/p/a4b6904d90aa)

在延伸一下，如何动态修改环境变量呢？

profile：（dev，test， exp，prod；）

如果不在application-.{profile}properties的文件中，我们可以通过重写

PropertySource注解配置

@Component
@ConfigurationProperties(prefix = "spring.datasource")
@PropertySource(value = "classpath:properties/druidConfig.properties", encoding = "UTF-8")//需要设置UTF-8，防止乱码
@Data
public class DruidConfig {
    ...
}

注意PropertySource，不支持classpath*，只支持classpath:
