- 配置管理系统提供系统参数配置管理,例如数据库的配置信息等,配置参数修改以后可以实时推送到客户端(基于netty4), 方便系统动态修改运行参数。
- 可以建多个项目,每个项目分为三种profile(development、test、production), 能够控制profile 级别的权限。
- 所有参数均由development profile配置,test和production profile继承development profile配置,也可以覆盖其配置。 test和production profile只提供修改功能。
- client 备份配置信息到本地文件系统,如果server不可用,可以使用本地备份。client 能够定时重连server,保证client高可用。
- client 提供ConfigurationListener,当某个属性发生变化(add、update、clear), ConfigurationListener能够接收到ConfigurationEvent。
- server 备份配置文件系统系统,如果数据库不用,能够保证对客户端提供数据(待完善)。

super-diamond-server中嵌入tomcat运行,构建部署包:mvn install assembly:single -Pproduction,生成super-diamond-server-1.0.0-SNAPSHOT-bin.tar.gz文件, 解压运行bin/server.sh start命令。
在conf\META-INF\scripts目录中,提供mysql和oracle建表脚本,理论也支持其它数据库,在conf\META-INF\res\config-production.properties文件中修改数据库配置。
在conf_user表中添加用户admin,密码000000的加密值为:670b14728ad9902aecba32e22fa4f6bd
客户端参考apache configuration,实现其中的部分功能。例如:
public class PropertiesConfigurationTest {
@Test
public void testConfig() throws ConfigurationRuntimeException {
String config = "username = melin \r\n";
config += "port=8000 \r\n";
config += "reload=true \r\n";
PropertiesConfiguration configuration = new PropertiesConfiguration();
configuration.load(config);
Assert.assertEquals("melin", configuration.getString("username"));
Assert.assertEquals(8000, configuration.getInt("port"));
Assert.assertTrue(configuration.getBoolean("reload"));
}
@Test
public void testInterpolator() throws ConfigurationRuntimeException {
String config = "app.home = /tmp/home \r\n";
config += "zk.home=${app.home}/zk \r\n";
config += "hbase.home=${app.home}/hbase \r\n";
PropertiesConfiguration configuration = new PropertiesConfiguration();
configuration.load(config);
Assert.assertEquals("/tmp/home", configuration.getString("app.home"));
Assert.assertEquals("/tmp/home/zk", configuration.getString("zk.home"));
Assert.assertEquals("/tmp/home/hbase", configuration.getString("hbase.home"));
}
@Test
public void testSysProperties() throws ConfigurationRuntimeException {
String config = "javaVersion = ${sys:java.version} \r\n";
PropertiesConfiguration configuration = new PropertiesConfiguration();
configuration.load(config);
Assert.assertEquals(System.getProperty("java.version"), configuration.getString("javaVersion"));
}
@Test
public void testSysEvns() throws ConfigurationRuntimeException {
String config = "javaHome = ${env:JAVA_HOME}/lib \r\n";
PropertiesConfiguration configuration = new PropertiesConfiguration();
configuration.load(config);
Assert.assertEquals(System.getenv("JAVA_HOME") + "/lib", configuration.getString("javaHome"));
}
}
PropertiesConfiguration config = new PropertiesConfiguration("localhost", 5001, "test", "development");
config.addConfigurationListener(new ConfigurationListenerTest());
config.getString("jdbc.url")
spring 使用方式
<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>
host和port可以在启动jvm时,通过参数配置 -Dspuerdiamond.host=127.0.0.1 -Dspuerdiamond.port=8283
<bean id="propertiesConfiguration" class="com.github.diamond.client.PropertiesConfigurationFactoryBean">
<constructor-arg index="0" value="test" />
<constructor-arg index="1" value="development" />
</bean>
ApplicationContext applicationContext = new ClassPathXmlApplicationContext("bean.xml");
PropertiesConfiguration config = PropertiesConfigurationFactoryBean.getPropertiesConfiguration();
config.getString("jdbc.url")
