搭建基于SpringBoot+sentry的日志报警系统

我们可以通过Sentry来收集线上错误日志并进行告警、监控及任务分配处理

初始化项目

通过初始化项目。

依赖：

Spring Web

集成Sentry

在pom.xml中dependencies节点下添加如下配置

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

添加配置文件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();
    }

}

添加测试的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程序后启动

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

启动后访问：http://127.0.0.1:8080报错，我们就完成了Sentry的基本集成，查看日志发现由于我们没有配置DSN，Sentry不会做任何操作

*** Couldnt find a suitable DSN, Sentry operations will do nothing! See documentation: https://docs.sentry.io/clients/java/ ***

我们在官网sentry.io中注册登录后创建我们的Sentry项目

创建成功后在配置中找到DNS，并复制

配置DSN：

在SpringBoot项目的resources目录新建一个sentry.properties，并添加以下配置

stacktrace.app.packages=   #关闭无关的warning
dsn=https://public:private@host:port/1  #位置setting-project（选中你sentry项目）-SDK-SETUP-Client keys(DSN)，第一个DSN

请求DefaultController 的，会抛出异常，此时登录sentry查看，成功收集到了第一条错误
