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Spring initializr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.bohanzhang.sentry;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
public class DefaultController {
@GetMapping
public void index() {
throw new NullPointerException();
}
}
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
*** Couldn't 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有以下种方法
在sentry.properties
中设置
dsn=https://public:private@host:port/1
在Java属性中配置
$ java -Dsentry.dsn=https://public:private@host:port/1 -jar target/sentry-0.0.1-SNAPSHOT.jar
在环境变量中配置
SENTRY_DSN=https://public:private@host:port/1 java -jar target/sentry-0.0.1-SNAPSHOT.jar
在代码中配置
import io.sentry.Sentry;
Sentry.init("https://public:private@host:port/1");
我们成功收集到了第一条错误
