java - Spring Boot 与 Datadog 的集成

问题描述

我有一个简单的 springboot 应用程序并尝试将 datadog 代理与其集成，但无法使用 Javaagent 运行该应用程序。已完成以下步骤。

在 pom.xml 中添加了依赖项。


    <dependency>
    <groupId>com.datadoghq</groupId>
    <artifactId>dd-java-agent</artifactId>
    <version>0.83.2</version>
    </dependency>

解压缩 datadog 依赖项和添加的类 ------------

<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-dependency-plugin</artifactId>
<version>3.1.1</version>
<executions>
<execution>
<phase>prepare-package</phase>
<goals>
<goal>unpack-dependencies</goal>
</goals>
<configuration>
<includeArtifactIds>dd-java-agent</includeArtifactIds>
<outputDirectory>${project.build.outputDirectory}</outputDirectory>
</configuration>
</execution>
</executions>
</plugin>

added premain class of datadog agent -----

    <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-jar-plugin</artifactId>
    <version>2.5</version>
    <configuration>
    <archive>
    <manifestEntries>
    <Premain-Class>datadog.trace.bootstrap.AgentBootstrap</Premain-Class>
    <Can-Redefine-Classes>true</Can-Redefine-Classes>
    <Can-Retransform-Classes>true</Can-Retransform-Classes>
    </manifestEntries>
    </archive>
    </configuration>
    </plugin>

添加了制作spring repackager插件以查找springboot主类-----------

<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<version>2.3.4.RELEASE</version>
<configuration>
<mainClass>com.user.info.userInfoApplication</mainClass>
</configuration>
</plugin>

        

Finally when issuing below command fails 

    java -javaagent:user-info-0.0.1-SNAPSHOT.jar -jar user-info-0.0.1-SNAPSHOT.jar
    
    Exception in thread "main" java.lang.ClassNotFoundException: datadog.trace.bootstrap.AgentBootstrap

            at java.base/jdk.internal.loader.ClassLoaders$AppClassLoader.loadClass(ClassLoaders.java:178)
            at java.base/java.lang.ClassLoader.loadClass(ClassLoader.java:521)
            at java.instrument/sun.instrument.InstrumentationImpl.loadClassAndStartAgent(InstrumentationImpl.java:431)
            at java.instrument/sun.instrument.InstrumentationImpl.loadClassAndCallPremain(InstrumentationImpl.java:525)
    FATAL ERROR in native method: processing of -javaagent failed
