1. 設置java環境變量等：
export JAVA_HOME=/home/yjiang2/jdk/jdk13-dwhite-centos7.5
export PATH=$JAVA_HOME/bin:$PATH
export SPECJBB_HOME=/home/yjiang2/specjbb
export CLASSPATH=.:$JAVA_HOME/lib:$SPECJBB_HOME/lib
2. 碰到Error： java.lang.NoClassDefFoundError: javax/xml/bind/JAXBException

問題分析：
JAXB API類作爲Java 6/7/8中JDK的一部分提供的。由於JAXB API被認爲是Java EE API，因此不再包含在Java SE 9的默認類路徑中。新版本的jdk13也不包含，需要自行下載。進入specjbb/lib目錄，用下面命令下載
wget http://search.maven.org/remotecontent?filepath=com/sun/activation/javax.activation/1.2.0/javax.activation-1.2.0.jar -O javax.activation-1.2.0.jar
wget http://search.maven.org/remotecontent?filepath=javax/xml/bind/jaxb-api/2.3.0/jaxb-api-2.3.0.jar -O jaxb-api-2.3.0.jar
wget http://search.maven.org/remotecontent?filepath=com/sun/xml/bind/jaxb-core/2.3.0/jaxb-core-2.3.0.jar -O jaxb-core-2.3.0.jar
wget http://search.maven.org/remotecontent?filepath=com/sun/xml/bind/jaxb-impl/2.3.0/jaxb-impl-2.3.0.jar -O jaxb-impl-2.3.0.jar
解決方法:
下載好JAXB相關庫後，給運行的java 添加-Xbootclasspath 參數包含JAXB庫
java -Xbootclasspath/a:/home/yjiang2/jdk/jdk13-dwhite-centos7.5/lib/jaxb-api-2.3.0.jar:/home/yjiang2/jdk/jdk13-dwhite-centos7.5/lib/jaxb-core-2.3.0.jar:/home/yjiang2/jdk/jdk13-dwhite-centos7.5/lib/jaxb-impl-2.3.0.jar:/home/yjiang2/jdk/jdk13-dwhite-centos7.5/lib/javax.activation-1.2.0.jar
3. 需要進入specjbb目錄，運行
/home/yjiang2/jdk/jdk13-dwhite-centos7.5/bin/java -Xbootclasspath/a:/home/yjiang2/jdk/jdk13-dwhite-centos7.5/lib/jaxb-api-2.3.0.jar:/home/yjiang2/jdk/jdk13-dwhite-centos7.5/lib/jaxb-core-2.3.0.jar:/home/yjiang2/jdk/jdk13-dwhite-centos7.5/lib/jaxb-impl-2.3.0.jar:/home/yjiang2/jdk/jdk13-dwhite-centos7.5/lib/javax.activation-1.2.0.jar -Xms210g -Xmx210g -Xmn208g -XX:+UseParallelOldGC -XX:ParallelGCThreads=224 -XX:TargetSurvivorRatio=95 -XX:SurvivorRatio=55 -XX:MaxTenuringThreshold=15 -XX:-UseAdaptiveSizePolicy -XX:+AlwaysPreTouch -XX:-UsePerfData -XX:+UseBiasedLocking -XX:+UseLSE -XX:+UseNUMA -XX:-UseNUMAInterleaving -XX:InlineSmallCode=20k -XX:CompileThreshold=1000 -XX:+AvoidUnalignedAccesses -XX:+UseSIMDForMemoryOps -XX:-UseFPUForSpilling -XX:-SegmentedCodeCache -XX:MaxInlineLevel=15 --add-modules ALL-SYSTEM -Dspecjbb.controller.rtcurve.warmup.step=0.7 -Dspecjbb.forkjoin.workers.Tier1=200 -Dspecjbb.forkjoin.workers.Tier2=1 -Dspecjbb.forkjoin.workers.Tier3=32 -Dspecjbb.customerDriver.threads=96 -jar /home/yjiang2/specjbb/specjbb2015.jar -m COMPOSITE -p /home/yjiang2/specjbb/config/specjbb2015.props
儘管我運行java命令時-p 指定了 specjbb的specjbb2015.props
-p /home/yjiang2/specjbb/config/specjbb2015.props
運行的時候還是報錯
