本片将主要说明QuickAlarm该如何使用，以及使用时需要注意事项
1. 基本使用姿势
首先我们不做任何的自定义操作，全部依靠系统默认的实现，我们的使用步骤如下
1. 添加注册文件
首先在项目的资源目录下，添加注册文件 alarm.properties，文件内容如下
## 应用名，必填
appName=test
## 报警规则文件所在的路径，如果采用系统默认加载方式，必填
## / 开头，表示存的是绝对路径
## 非/开头，表示存的是系统相对路径，一般是放在资源目录下
alarmConfPath=/tmp/alarmConfig
## 最大的报警类型，非必填
maxAlarmType=1000
## 默认报警用户，必填
defaultAlarmUsers=yihui
具体存放的位置，可以参考下图，放在resources目录下（源码中，是放在测试资源目录下的）
2. 添加报警规则
根据注册文件中指定的路径，设置报警规则文件，如我们的报警规则文件
内容为json串格式，支持格式化的json串解析，为了节省篇幅，下面压缩成一行，点击获取json格式化小工具
/tmp/alarmConig:
{"default":{"level":"LOG","autoIncEmergency":true,"max":30,"min":3,"threshold":[{"level":"SMS","threshold":20,"users":["345345345345","123123123123"]},{"level":"WEIXIN","threshold":10,"users":["yihui","erhui"]},{"level":"LOG","threshold":5,"users":["yihui","erhui"]}],"users":["yihui"]},"NPE":{"level":"WEIXIN","autoIncEmergency":false,"max":30,"min":0,"threshold":[{"level":"SMS","threshold":20,"users":["345345345345","123123123123"]},{"level":"WEIXIN","threshold":10,"users":["3h ui","4hui"]}],"users":["yihui"]},"XXX,YYY":{"level":"EMAIL","autoIncEmergency":true,"max":30,"min":3,"threshold":[{"level":"SMS","threshold":20,"users":["345345345345","123123123123"]},{"level":"WEIXIN","threshold":10,"users":["yihui","erhui"]},{"level":"EMAIL","threshold":5,"users":["[email protected]","[email protected]"]}],"users":["[email protected]"]}}
3. 测试类
一个简单的使用测试
@Test
public void sendMsg() throws InterruptedException {
String key = "NPE";
String title = "NPE异常";
String msg = "出现NPE异常了!!!";
AlarmWrapper.getInstance().sendMsg(key, title, msg); // 微信报警
// 不存在异常配置类型, 采用默认报警, 次数较小, 则直接部署出
AlarmWrapper.getInstance().sendMsg("zzz", "不存在xxx异常配置", "报警嗒嗒嗒嗒");
Thread.sleep(1000);
}
II. 报警执行机器扩展
前面的报警规则配置中，有WEIXIN, SMS, EMAIL的报警，但是系统只提供了两个NONE和LOG，所以我们可以看下如何自定义实现上面的三个
1. 实现IExecute接口
邮件报警
public class EmailExecute extends LogExecute {
@Override
public void sendMsg(List<String> users, String title, String msg) {
super.sendMsg(users, title, msg);
}
}
短信报警
/**
* Created by yihui on 2018/2/7.
*/
public class SmsExecute extends LogExecute {
@Override
public void sendMsg(List<String> users, String title, String msg) {
super.sendMsg(users, title, msg);
}
}
微信报警
/**
* Created by yihui on 2018/2/7.
*/
public class WeiXinExecute extends LogExecute {
@Override
public void sendMsg(List<String> users, String title, String msg) {
super.sendMsg(users, title, msg);
}
}
说明，因为没有具体的实现，所以我们直接用日志输出来模拟，所以就都继承了LogExecute, 实际使用中，可以在上面补上相应的实现代码
2. 添加SPI定义
在 resources 目录下，新增
- 目录：META-INF/services/
- 文件：com.hust.hui.alarm.core.execut.api.IExecute
文件内容为上面几个实现类的全路径
com.hust.hui.alarm.core.test.execute.EmailExecute
com.hust.hui.alarm.core.test.execute.SmsExecute
com.hust.hui.alarm.core.test.execute.WeiXinExecute
目录结构如：
3. 测试
public static void main(String[] args) throws InterruptedException {
// 测试异常升级的case
// 计数 [1 - 2] 默认报警（即无日志） （其中 < 3 的是因为未达到下限, 采用的默认报警）
// 计数 [3 - 4] 默认邮件报警（其中 < 5 采用的默认报警, 与下面的区别是报警用户）
// 计数 [5 - 9] 邮件报警 （大于5小于10根据上升规则,还是选择邮件报警）
// 计数 [10 - 19] 微信报警
// 计数 [20 - 30] 短信报警
// 计数 [31 -] 默认报警 （超过上限, 不报警）
for (int i = 0; i < 40; i++) {
new Thread(new Runnable() {
@Override
public void run() {
AlarmWrapper.getInstance().sendMsg("YYY", "异常报警升级测试");
}
}).start();
}
Thread.sleep(1000 * 600);
}
实测输出结果如下:

III. 报警规则加载自定义
1. 实现IConfLoader接口
自定义加载器，给了一个最基本的
public class SelfAlarmConfLoader implements IConfLoader {
@Override
public RegisterInfo getRegisterInfo() {
RegisterInfo registerInfo = new RegisterInfo();
registerInfo.setMaxAlarmType(100);
registerInfo.setDefaultAlarmUsers("yihui");
registerInfo.setAppName("test");
return registerInfo;
}
@Override
public boolean alarmEnable() {
return true;
}
@Override
public int order() {
return 0;
}
@Override
public AlarmConfig getAlarmConfig(String alarmKey) {
//db 查询，获取对应的配置信息
// 下面是模拟，返回一个固定的配置
AlarmConfig alarmConfig = new AlarmConfig();
alarmConfig.setAlarmLevel("WEIXIN");
alarmConfig.setAutoIncEmergency(false);
alarmConfig.setMinLimit(10);
alarmConfig.setMaxLimit(14);
alarmConfig.setUsers(Arrays.asList("yihui"));
alarmConfig.setAlarmThreshold(Collections.emptyList());
return alarmConfig;
}
}
2. 添加SPI配置
在resources目录下新增
- 目录： META-INF/services
- 文件： com.hust.hui.alarm.core.loader.api.IConfLoader
文件内容
com.hust.hui.alarm.core.test.loader.SelfAlarmConfLoader
3. 测试
同样是上面的代码，输出结果
18:43:04.275 [sms-sender1-thread-2] INFO alarm - Do send msg by WEIXIN to user:[yihui], title: [test], msg: ip:172.17.13.18 >>> key:YYY >>> 异常数: 10 >>> 异常报警升级测试
18:43:04.275 [sms-sender1-thread-4] INFO alarm - Do send msg by WEIXIN to user:[yihui], title: [test], msg: ip:172.17.13.18 >>> key:YYY >>> 异常数: 12 >>> 异常报警升级测试
18:43:04.276 [sms-sender1-thread-1] INFO alarm - Do send msg by WEIXIN to user:[yihui], title: [test], msg: ip:172.17.13.18 >>> key:YYY >>> 异常数: 11 >>> 异常报警升级测试
18:43:04.275 [sms-sender1-thread-5] INFO alarm - Do send msg by WEIXIN to user:[yihui], title: [test], msg: ip:172.17.13.18 >>> key:YYY >>> 异常数: 14 >>> 异常报警升级测试
18:43:04.275 [sms-sender1-thread-3] INFO alarm - Do send msg by WEIXIN to user:[yihui], title: [test], msg: ip:172.17.13.18 >>> key:YYY >>> 异常数: 13 >>> 异常报警升级测试
4. 说明
系统默认的order是10，所以如果在测试上面的第二步时，不妨把com.hust.hui.alarm.core.test.loader.SelfAlarmConfLoader#order返回值，改成大于10，这样就会走到默认的配置加载类
采用 SelfAlarmConfLoader 时，前面说的两个基础配置文件，是可以没有的，完全不会有任何影响，因为对应的注册类和报警规则，都是右这个类内部提供了
IV. 小结
所有测试相关数据，均可以在测试工程中获取，请主要关注:
- 测试case
- 注册文件：alarmConfig
