spring boot 集成 superdiamond

摘要: spring boot很好用，superdiamond是同事推荐的配置管理服务，也不错，两者怎么集成呢？

spring boot用spring新的 Enviroment 类来管理属性配置。Super diamond (https://github.com/melin/super-diamond) 默认给的是用 以下配置

<bean class="org.springframework.context.support.PropertySourcesPlaceholderConfigurer">
<property name="properties" ref="propertiesConfiguration" />
</bean>

<bean id="propertiesConfiguration" class="com.github.diamond.client.PropertiesConfigurationFactoryBean">
<constructor-arg index="0" value="localhost" />
<constructor-arg index="1" value="5001" />
<constructor-arg index="2" value="test" />
<constructor-arg index="3" value="development" />
</bean>

这样的配置导致superdiamond的配置信息是优先级最低，不能起到集中管理，覆盖打包到jar中的application.properties的目的。如果设置PropertySourcesPlaceHoderConfigurer 的 localOverride = true 的话，那么superdiamond的优先级又太高。总之我希望superdiamond的配置优先级要低于环境变量和jvm properties，但是要高于application properties。那就不要用PropertySourcesPlaceHoderConfigurer了，直接把propertie插入到Enviroment里面就好了。

SpringApplication app = new SpringApplication(Application.class);
app.addInitializers((ApplicationContextInitializer<ConfigurableApplicationContext>) applicationContext -> {
ConfigurableEnvironment environment = applicationContext.getEnvironment();
if (Arrays.stream(environment.getActiveProfiles())
.filter(x -> "superdiamond".equals(x)).findAny().isPresent()) {
try {
loadSuperDiamond(environment);
} catch (Exception e) {
e.printStackTrace();
}
}
});
app.run(args);
}

static void loadSuperDiamond(ConfigurableEnvironment enviroment) throws Exception {
PropertiesConfigurationFactoryBean propertiesConfigurationFactoryBean = new PropertiesConfigurationFactoryBean(
enviroment.getProperty("superdiamond.host"),
Integer.parseInt(enviroment.getProperty("superdiamond.port")),
enviroment.getProperty("superdiamond.proj", "superdiamond.proj"),
enviroment.getProperty("superdiamond.profile", "superdiamond.profile"),
enviroment.getProperty
3ff0
("superdiamond.modules", "superdiamond.modules")
);
Properties properties = propertiesConfigurationFactoryBean.getObject();
enviroment.getPropertySources().addAfter("random", new PropertiesPropertySource("superdiamond", properties));
}
