搭建基於SpringBoot+sentry的日誌報警系統

我們可以通過Sentry來收集線上錯誤日誌並進行告警、監控及任務分配處理

初始化專案

通過Spring initializr初始化專案。

依賴：

• Spring Web

整合Sentry

在pom.xml中dependencies節點下新增如下設定

<dependency>
    <groupId>io.sentry</groupId>
    <artifactId>sentry-spring</artifactId>
    <version>1.7.30</version>
</dependency>

新增組態檔SentryConfig.java

@Configuration
public class SentryConfig {

    @Bean
    public HandlerExceptionResolver sentryExceptionResolver() {
        return new io.sentry.spring.SentryExceptionResolver();
    }

    @Bean
    public ServletContextInitializer sentryServletContextInitializer() {
        return new io.sentry.spring.SentryServletContextInitializer();
    }

}

新增測試的DefaultController.java

package com.testdemo.sentry;

import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class SentryController {

    @GetMapping
    public void index() {
        throw new NullPointerException();
    }

    @GetMapping(value = "/user")
    public void getUser() {
        throw new IndexOutOfBoundsException("user size=10,req=11");
    }
}

打包Spring-boot程式後啓動

$ ./mvnw package
$ java -jar target/sentry-0.0.1-SNAPSHOT.jar

啓動後存取：http://127.0.0.1:8080報錯，我們就完成了Sentry的基本整合，檢視日誌發現由於我們沒有設定DSN，Sentry不會做任何操作

*** Couldn't find a suitable DSN, Sentry operations will do nothing! See documentation: https://docs.sentry.io/clients/java/ ***

我們在官網sentry.io中註冊登錄後建立我們的Sentry專案

 

建立成功後在設定中找到DNS，並複製

設定DSN：

在SpringBoot專案的resources目錄新建一個sentry.properties，並新增以下設定

stacktrace.app.packages=   #關閉無關的warning
dsn=https://public:private@host:port/1  #位置setting-project（選中你sentry專案）-SDK-SETUP-Client keys(DSN)，第一個DSN

 

請求DefaultController 的，會拋出異常，此時登錄sentry檢視，成功收集到了第一條錯誤
