我在运行jetty服务器时得到的错误堆栈跟踪：

java.lang.IllegalStateException: Must start with Java agent to use InstrumentationLoadTimeWeaver. See Spring documentation.

根据此错误，我在MAVEN_OPTS中添加了instrumentation jar

export MAVEN_OPTS="-server -Djava.net.preferIPv4Stack=true
         -Denv=$PWD/../$2 -Dcom.sun.management.jmxremote
         -Dcom.sun.management.jmxremote.port=9005
         -Dcom.sun.management.jmxremote.authenticate=false
         -Dcom.sun.management.jmxremote.ssl=false
         -Dcom.sun.management.jmxremote.local.only=false
         -Djava.rmi.server.hostname=$myip
         -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=/tmp -Xmx1500m -Xms1500m -XX:PermSize=256m -XX:MaxPermSize=1g -XX:NewSize=500m -XX:MaxNewSize=500m -XX:+UseParNewGC -XX:+UseConcMarkSweepGC -XX:+CMSParallelRemarkEnabled -XX:SurvivorRatio=8 -XX:MaxTenuringThreshold=1 -XX:CMSInitiatingOccupancyFraction=75 -XX:+UseCMSInitiatingOccupancyOnly -XX:+UseTLAB  -javaagent:/Users/jyotigupta/.m2/repository/org/springframework/spring-instrument/4.2.1.RELEASE/spring-instrument-4.2.1.RELEASE.jar "

我在pom依赖中使用spring 4.2.1.RELEASE。所以，我认为这应该是正确的。

以下是我的弹簧配置，用于加载时编织。

        <bean id="loadTimeWeaver"
            class="org.springframework.instrument.classloading.InstrumentationLoadTimeWeaver" />

</beans>

请帮忙。

Answer 1

使用org.mortbay.jetty.plugin.JettyServer.doStart()（又名jetty-maven-plugin）

时，没有java代理

可以想象jetty-maven-plugin需要支持使用自定义jvm参数的分叉执行来关闭它（它目前不支持）

顺便提一下，org.mortbay.jetty部分表示您正在使用旧插件（已将其移至org.eclipse.jetty）

如果这对您很重要，请在以下位置提交功能请求：

AspectJ loadtimeweaving不能使用spring，jetty用于aws-swf @Asynchronous
