创建配置文件

在敲Demo之前，需要在Disconf上创建自己的APP，然后在APP的某个环境下创建配置文件，如下面截图中的流程，这里就简单创建了一个redis.properties，内容是redis的IP和端口号，Key值分别是redis.host和redis.port。

创建Demo

1、使用工具

Eclipse Kepler Release

Maven

2、创建项目

创建一个Maven Project，修改pom.xml文件，加载所需要的jar包。

[html] view plain copy

<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<guava.version>16.0.1</guava.version>
<java.version>1.7</java.version>
</properties>
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.3.2.RELEASE</version>
</parent>
<dependencies>
<dependency>
<groupId>com.baidu.disconf</groupId>
<artifactId>disconf-client</artifactId>
<version>2.6.31</version>
</dependency>
<dependency>
<groupId>redis.clients</groupId>
<artifactId>jedis</artifactId>
<version>2.1.0</version>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter</artifactId>
<exclusions>
<exclusion>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-logging</artifactId>
</exclusion>
</exclusions>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-log4j</artifactId>
</dependency>
</dependencies>
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
</plugins>
</build>

2、添加配置文件

在resources包下添加配置文件，分别为applicationContext.xml、disconf.properties，如果需要的话，还要添加log4j的配置文件，以便查看控制台打印的信息。

applicationContext.xml，要注意修改红色加粗部分，修改为自己创建的包路径。

[html] view plain copy

<property name="ignoreUnresolvablePlaceholders" value="true" />
<property name="propertiesArray">
<list>
<ref bean="configproperties_disconf" />
</list>
</property>
</bean>
</beans>

disconf.properties，具体的配置项可以参考官网：http://disconf.readthedocs.io/zh_CN/latest/config/src/client-config.html#disconf-client

[html] view plain copy

# 是否使用远程配置文件，true(默认)会从远程获取配置，false则直接从本地获取配置
disconf.enable.remote.conf=true
# 配置服务器的HOST，用逗号分隔
disconf.conf_server_host=192.168.111.130:8080
# 版本号
disconf.version=1.0.0
# APP的名称
disconf.app=YZEvaluationSystem
# 添加的配置文件所在的环境
disconf.env=local
# 忽略分布式配置
disconf.ignore=
# 获取远程配置重试次数
disconf.conf_server_url_retry_times=1
# 获取远程配置重试时休眠时间
disconf.conf_server_url_retry_sleep_seconds=1
# 用户自定义的下载路径
disconf.user_define_download_dir=./config

log4j.xml

[html] view plain copy

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">
<log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/" debug="false">
<appender name="CONSOLE" class="org.apache.log4j.ConsoleAppender">
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="[%d{dd/MM/yy hh:mm:ss:sss z}] %t %5p %c{2}: %m%n" />
</layout>
</appender>
<root>
<level value="INFO" />
<appender-ref ref="CONSOLE" />
</root>
</log4j:configuration>

3、创建相应的类

在创建好的包路径下创建一个JedisConfig类和DisconfRunMain类。

JedisConfig类

[java] view plain copy

package com.tgb.service;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.context.annotation.Configuration;
import com.baidu.disconf.client.common.annotations.DisconfFileItem;
import com.baidu.disconf.client.common.update.IDisconfUpdate;
@Configuration
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);
}
}

DisconfRunMain类

[java] view plain copy

package com.tgb.service;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ImportResource;
@SpringBootApplication
@ImportResource({ "classpath:applicationContext.xml" })
// 引入disconf
public class DisconfRunMain{
public static void main(String args[]) {
SpringApplication.run(Application.class, args);
}
}

4、执行main方法

在main方法上右键run as Java Application即可启动，启动过程会打印Spring Boot启动信息、Disconf的初始化配置信息、连接Zookeeper的信息以及打印出redis.properties文件的内容信息。从文件夹中查看项目，会发现项目路径下多出一个config文件夹，里面是下载到本地的redis.properties文件，是因为在disconf.properties中设置了下载路径为./config。
