上一章介绍了disconf的安装预配置，这章主要介绍下disconf与spring集成

1、添加依赖

<dependency>
                <groupId>com.baidu.disconf</groupId>
                <artifactId>disconf-client</artifactId>
                <version>2.6.36</version>
            </dependency>

2、修改配置文件

修改spring的配置文件spring-config.xml

添加初始化配置

<bean id="disconfMgrBean" class="com.baidu.disconf.client.DisconfMgrBean"
    		destroy-method="destroy">
    		<property name="scanPackage" value="com.abcde" />
    	</bean>
    	<bean id="disconfMgrBean2" class="com.baidu.disconf.client.DisconfMgrBeanSecond"
    		init-method="init" destroy-method="destroy">
    	</bean>
    
    	<aop:aspectj-autoproxy />

增加一个disconf.properties配置文件到classpath下：

# 是否使用远程配置文件
    # true(默认)会从远程获取配置 false则直接获取本地配置
    disconf.enable.remote.conf=true
    
    #
    # 配置服务器的 HOST,用逗号分隔  127.0.0.1:8004,127.0.0.1:8004
    #
    disconf.conf_server_host=172.20.50.26:8990
    #disconf.conf_server_host=127.0.0.1:80
    
    # 版本, 请采用 X_X_X_X 格式 
    disconf.version=1_0_0_0
    
    # APP 请采用 产品线_服务名 格式 
    disconf.app=pinganwj_appt
    
    # 环境disco
    disconf.env=dev
    
    # 忽略哪些分布式配置，用逗号分隔
    disconf.ignore=
    
    # 获取远程配置 重试次数，默认是3次
    disconf.conf_server_url_retry_times=1
    # 获取远程配置 重试时休眠时间，默认是5秒
    disconf.conf_server_url_retry_sleep_seconds=1
    
    # 用户指定的下载文件夹, 远程文件下载后会放在这里
    disconf.user_define_download_dir=./disconf/download
    
    # 下载的文件会被迁移到classpath根路径下，强烈建议将此选项置为 true(默认是true)
    disconf.enable_local_download_dir_in_class_path=true

3、通过xml的分布式配置

添加静态配置文件

<bean id="configproperties_no_reloadable_disconf"
    		class="com.baidu.disconf.client.addons.properties.ReloadablePropertiesFactoryBean">
    		<property name="locations">
    			<list>
    				<value>file:config/global.properties</value>
    				<value>file:config/jdbc.properties</value>
    				<value>file:config/config-db.properties</value>
    				<value>file:config/clinic-api.properties</value>
    			</list>
    		</property>
    	</bean>
    <bean id="propertyConfigurerForProject1" class="com.abcde.core.base.utils.PropertyPlaceholder">
    		<property name="ignoreResourceNotFound" value="true" />
    		<property name="ignoreUnresolvablePlaceholders" value="true" />
    		<property name="propertiesArray">
    			<list>
    				<ref bean="configproperties_no_reloadable_disconf" />
    			</list>
    		</property>
    	</bean>

添加动态配置（托管式），启动时下载配置文件；配置文件变化时，负责动态推送。程序不会自动reload配置，需要自己写回调函数(实现IDisconfUpdate接口，并添加DisconfUpdateService注解)。

<bean id="configproperties_reloadable_disconf"
    		class="com.baidu.disconf.client.addons.properties.ReloadablePropertiesFactoryBean">
    		<property name="locations">
    			<list>
    				<value>file:config/kafka.properties</value>
    				<value>file:config/emailSendConfig.properties</value>
    			</list>
    		</property>
    	</bean>
    
    <bean id="propertyConfigurerForProject"
    		class="com.baidu.disconf.client.addons.properties.ReloadingPropertyPlaceholderConfigurer">
    		<property name="ignoreResourceNotFound" value="true" />
    		<property name="ignoreUnresolvablePlaceholders" value="true" />
    		<property name="propertiesArray">
    			<list>
    				<ref bean="configproperties_reloadable_disconf" />
    			</list>
    		</property>
    	</bean>

@Component
    @DisconfUpdateService(confFileKeys = { "kafaka.properties" })
    public class KafakaConfigCallback implements IDisconfUpdate {
    
        @Override
        public void reload() throws Exception {
        }
    
    }

4、基于注解的分布式配置

@Configuration    
    @DisconfFile(filename="redis.properties")  
    public class JedisConfig implements IDisconfUpdate {    
        
        protected static final Logger LOGGER = LoggerFactory    
                .getLogger(JedisConfig.class);    
        
        // 代表连接地址    
        private String host;    
        
        // 代表连接port    
        private int port;    
        
        /**  
         * 地址, 分布式文件配置  
         *   
         * @return  
         */    
        @DisconfFileItem(name = "redis.host", associateField = "host")    
        public String getHost() {    
        
            return host;    
        }    
        
        public void setHost(String host) {    
        
            this.host = host;    
        }    
        
        /**  
         * 端口, 分布式文件配置  
         *   
         * @return  
         */    
        @DisconfFileItem(name = "redis.port", associateField = "port")    
        public int getPort() {    
        
            return port;    
        }    
        
        public void setPort(int port) {    
        
            this.port = port;    
        }    
        
        public void reload() throws Exception {    
        
            LOGGER.info("host: " + host);    
        }    
    }
