07、注解式分布式静态配置文件和静态配置项

4.1. 配置类

定义

package com.example.disconf.demo.config;

import com.baidu.disconf.client.common.annotations.DisconfFile;
import com.baidu.disconf.client.common.annotations.DisconfFileItem;

/**
 * 静态 配置文件 示例
 *
 * @author liaoqiqi
 * @version 2022-6-17
 */
@DisconfFile(filename = "static.properties")
public class StaticConfig {

    private static int staticVar;

    @DisconfFileItem(name = "staticVar", associateField = "staticVar")
    public static int getStaticVar() {
        return staticVar;
    }

    public static void setStaticVar(int staticVar) {
        StaticConfig.staticVar = staticVar;
    }

}

使用

package com.example.disconf.demo.service;

import com.baidu.disconf.client.common.annotations.DisconfItem;
import com.example.disconf.demo.config.StaticConfig;

/**
 * 使用静态配置文件的示例<br/>
 * Plus <br/>
 * 静态配置项 使用示例
 *
 * @author liaoqiqi
 * @version 2022-8-14
 */
public class SimpleStaticService {

    private static int staticItem = 56;

    /**
     *
     * @return
     */
    public static int getStaticFileData() {

        return StaticConfig.getStaticVar();
    }
}

和

LOGGER.info("static file data:"
                        + SimpleStaticService.getStaticFileData());

4.2. 配置项

定义

package com.example.disconf.demo.service;

import com.baidu.disconf.client.common.annotations.DisconfItem;
import com.example.disconf.demo.config.StaticConfig;

/**
 * 使用静态配置文件的示例<br/>
 * Plus <br/>
 * 静态配置项 使用示例
 *
 * @author liaoqiqi
 * @version 2022-8-14
 */
public class SimpleStaticService {

    private static int staticItem = 56;

    /**
     *
     * @return
     */
    public static int getStaticFileData() {

        return StaticConfig.getStaticVar();
    }

    @DisconfItem(key = "staticItem")
    public static int getStaticItem() {
        return staticItem;
    }

    public static void setStaticItem(int staticItem) {
        SimpleStaticService.staticItem = staticItem;
    }
}

使用

LOGGER.info("static item data:"
+ SimpleStaticService.getStaticItem());
