1.1 下载解压
# 下载最新版本的JVM-SANDBOX
wget http://ompc.oss-cn-hangzhou.aliyuncs.com/jvm-sandbox/release/sandbox-stable-bin.zip
# 解压
unzip sandbox-stable-bin.zip1.2 挂载目标应用
# 进入沙箱执行脚本
cd sandbox/bin
# 常用命令!!!
# 目标JVM进程73366(假设，使用jps命令查看)
./sandbox.sh -p 73366
#卸载沙箱
./sandbox.sh -p 73366 -S
#查询沙箱
./sandbox.sh -p 73366 -l
#刷新沙箱
./sandbox.sh -p 73366 -F
#使用自定义module执行(my-sandbox-module:自定义的module名字，addLog自定义切入方法名字)
./sandbox.sh -p 73366 -d 'my-sandbox-module/addLog'
#日志配置及查看
#配置文件在 /sandbox/cfg/sandbox-logback.xml
#默认日志路径 ~/logs/sandbox/sandbox.log
本例采用maven多工程模式：(注意自己的父子结构引用)

@SpringBootApplication

需要被挂载切入方法的类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;

@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);
}
}打包上传服务器使用java -jar 启动
切入方法类MySandBoxModule
import com.alibaba.jvm.sandbox.api.Information;

@MetaInfServices(Module.class)
@Information(id = "my-sandbox-module")// 模块名,在指定挂载进程后通过-d指定模块,配合@Command注解来唯一确定方法
@Slf4j
public class MySandBoxModule implements Module {
@Resource
private ModuleEventWatcher moduleEventWatcher;
@Command("addLog")// 模块命令名
public void addLog() {
new EventWatchBuilder(moduleEventWatcher)
.onClass("com.sandbox.test.TestSandbox")// 想要对 TestSandbox 这个类进行切面
.onBehavior("test")// 想要对上面类的 bathSave 方法进行切面
.onWatch(new AdviceListener() {
//对方法执行之前执行
@Override
protected void before(Advice advice) throws Throwable {
log.info("sandbox切入成功!!!!!!");
//获取方法的所有参数
Object[] parameterArray = advice.getParameterArray();
if (parameterArray != null) {
for (Object po : parameterArray) {
log.info("形参类型为:" + po.getClass().getName() + "!!!!!!!");
log.info("形参值为:" + po + "!!!!!!!");
}
}
}
});
}
}使用 mvn clean compile assembly:single打包，上传至sandbox/sandbox-module目录下
