jvm-sandbox使用
1 快速安裝
1.1 下載解壓
# 下載最新版本的JVM-SANDBOX wget http://ompc.oss-cn-hangzhou.aliyuncs.com/jvm-sandbox/release/sandbox-stable-bin.zip # 解壓 unzip sandbox-stable-bin.zip1.2 掛載目標應用
# 進入沙箱執行指令碼 cd sandbox/bin # 常用命令!!! # 目標JVM程序73366(假設，使用jps命令檢視) ./sandbox.sh -p 73366 #解除安裝沙箱 ./sandbox.sh -p 73366 -S #查詢沙箱 ./sandbox.sh -p 73366 -l #重新整理沙箱 ./sandbox.sh -p 73366 -F #使用自定義module執行(my-sandbox-module:自定義的module名字，addLog自定義切入方法名字) ./sandbox.sh -p 73366 -d 'my-sandbox-module/addLog' #日誌配置及檢視 #配置檔案在 /sandbox/cfg/sandbox-logback.xml #預設日誌路徑 ~/logs/sandbox/sandbox.log
2 快速使用demo
本例採用maven多工程模式：(注意自己的父子結構引用)
主pom.xml(參考)

2.1 springboot-sandbox程式碼
啟動類SandboxApp
import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; @SpringBootApplication public class SandboxApp { public static void main(String[] args) { SpringApplication.run(SandboxApp.class, args); } }需要被掛載切入方法的類TestSandbox
import lombok.extern.slf4j.Slf4j; import org.springframework.boot.ApplicationArguments; import org.springframework.boot.ApplicationRunner; import org.springframework.stereotype.Component; import java.util.concurrent.atomic.LongAdder; @Slf4j @Component public class TestSandbox implements ApplicationRunner { private final LongAdder longAdder = new LongAdder(); @Override public void run(ApplicationArguments args) throws Exception { while (true) { longAdder.add(1); try { Thread.sleep(2000); } catch (InterruptedException e) { e.printStackTrace(); } test(longAdder); } } private void test(LongAdder longAdder) { log.info("TestSandBox------->" + longAdder); } }打包上傳伺服器使用java -jar 啟動
2.2 module-sandbox程式碼
切入方法類MySandBoxModule
import com.alibaba.jvm.sandbox.api.Information; import com.alibaba.jvm.sandbox.api.Module; import com.alibaba.jvm.sandbox.api.annotation.Command; import com.alibaba.jvm.sandbox.api.listener.ext.Advice; import com.alibaba.jvm.sandbox.api.listener.ext.AdviceListener; import com.alibaba.jvm.sandbox.api.listener.ext.EventWatchBuilder; import com.alibaba.jvm.sandbox.api.resource.ModuleEventWatcher; import lombok.extern.slf4j.Slf4j; import org.kohsuke.MetaInfServices; import javax.annotation.Resource; @MetaInfServices(Module.class) @Information(id = "my-sandbox-module")// 模組名,在指定掛載程序後通過-d指定模組,配合@Command註解來唯一確定方法 @Slf4j public class MySandBoxModule implements Module { @Resource private ModuleEventWatcher moduleEventWatcher; @Command("addLog")// 模組命令名 public void addLog() { new EventWatchBuilder(moduleEventWatcher) .onClass("com.sandbox.test.TestSandbox")// 想要對 TestSandbox 這個類進行切面 .onBehavior("test")// 想要對上面類的 bathSave 方法進行切面 .onWatch(new AdviceListener() { //對方法執行之前執行 @Override protected void before(Advice advice) throws Throwable { log.info("sandbox切入成功!!!!!!"); //獲取方法的所有引數 Object[] parameterArray = advice.getParameterArray(); if (parameterArray != null) { for (Object po : parameterArray) { log.info("形參型別為:" + po.getClass().getName() + "!!!!!!!"); log.info("形參值為:" + po + "!!!!!!!"); } } } }); } }使用 mvn clean compile assembly:single打包，上傳至sandbox/sandbox-module目錄下
2.3 使用命令掛載使用
