很多包的时候 还会卡死Java
的各种运行命令 来对程序进行优化java
Usage: java [-options] class [args...] (to execute a class) or java [-options] -jar jarfile [args...] (to execute a jar file) where options include: -d32 use a 32-bit data model if available -d64 use a 64-bit data model if available -server to select the "server" VM The default VM is server, because you are running on a server-class machine. -cp <class search path of directories and zip/jar files> -classpath <class search path of directories and zip/jar files> A : separated list of directories, JAR archives, and ZIP archives to search for class files. -D<name>=<value> set a system property -verbose:[class|gc|jni] enable verbose output -version print product version and exit -version:<value> Warning: this feature is deprecated and will be removed in a future release. require the specified version to run -showversion print product version and continue -jre-restrict-search | -no-jre-restrict-search Warning: this feature is deprecated and will be removed in a future release. include/exclude user private JREs in the version search -? -help print this help message -X print help on non-standard options -ea[:<packagename>...|:<classname>] -enableassertions[:<packagename>...|:<classname>] enable assertions with specified granularity -da[:<packagename>...|:<classname>] -disableassertions[:<packagename>...|:<classname>] disable assertions with specified granularity -esa | -enablesystemassertions enable system assertions -dsa | -disablesystemassertions disable system assertions -agentlib:<libname>[=<options>] load native agent library <libname>, e.g. -agentlib:hprof see also, -agentlib:jdwp=help and -agentlib:hprof=help -agentpath:<pathname>[=<options>] load native agent library by full pathname -javaagent:<jarpath>[=<options>] load Java programming language agent, see java.lang.instrument -splash:<imagepath> show splash screen with specified image See http://www.oracle.com/technetwork/java/javase/documentation/index.html for more details.
java -X
-Xmixed mixed mode execution (default) -Xint interpreted mode execution only -Xbootclasspath:<directories and zip/jar files separated by :> set search path for bootstrap classes and resources -Xbootclasspath/a:<directories and zip/jar files separated by :> append to end of bootstrap class path -Xbootclasspath/p:<directories and zip/jar files separated by :> prepend in front of bootstrap class path -Xdiag show additional diagnostic messages -Xnoclassgc disable class garbage collection -Xincgc enable incremental garbage collection -Xloggc:<file> log GC status to a file with time stamps -Xbatch disable background compilation -Xms<size> set initial Java heap size -Xmx<size> set maximum Java heap size -Xss<size> set java thread stack size -Xprof output cpu profiling data -Xfuture enable strictest checks, anticipating future default -Xrs reduce use of OS signals by Java/VM (see documentation) -Xcheck:jni perform additional checks for JNI functions -Xshare:off do not attempt to use shared class data -Xshare:auto use shared class data if possible (default) -Xshare:on require using shared class data, otherwise fail. -XshowSettings show all settings and continue -XshowSettings:all show all settings and continue -XshowSettings:vm show all vm related settings and continue -XshowSettings:properties show all property settings and continue -XshowSettings:locale show all locale related settings and continue The -X options are non-standard and subject to change without notice. The following options are Mac OS X specific: -XstartOnFirstThread run the main() method on the first (AppKit) thread -Xdock:name=<application name>" override default application name displayed in dock -Xdock:icon=<path to icon file> override default icon displayed in dock
-d64 #选择以64位Java运行 //@todo 检查你系统的Java是64还是32的 再使用此项 -server #选择以服务器的模式运行Java程序 -Xincgc #启用增量垃圾收集 -Xms <大小> #设置初始Java堆大小 -Xmx <大小> #设置最大Java堆大小 -Xss <大小> #设置Java线程堆栈大小
