Java Service Wrapper将java程序设置为服务
有时候我们希望我们java写的程序作为服务注册到系统中，Java Service Wrapper（下面简称wrapper）是目前较为流行的将Java程序部署成Windows服务的解决方案， 本文将讨论如何使用wrapper把我们的程序打包成WIN服务！
主要作用有:
1.打包服务
2.设置JVM参数
3.所有的日志可以输出到指定文件
0.准备需要注册为服务的程序
public class MapTest { private static int i; public static void main(String[] args) { while (true) { try { System.out.println("访问次数:" + i++); HttpUtil.doGet("http://www.cnblogs.com/qlqwjy/"); Thread.sleep(2 * 1000); } catch (InterruptedException e) { e.printStackTrace(); } } } }
上面程序依赖的jar包:
将上面程序也打成包:(使用eclipse打包或者直接Jdk自带的jar打包)
1.下载serviceWrapper包
下载地址:http://qiaoliqiang.cn/fileDown/wrapper-windows-x86-32-3.5.25.zip
下载后是一个压缩包，解压目录如下:
2.开始注册一个简单的服务:
1. 准备一个目录，例如我在桌面建了一个SW目录,并在里面新建如下结构的目录: 接下来全文的%EXAMPLE_HOME% 就是我新建的SW目录名称
%EXAMPLE_HOME%\ %EXAMPLE_HOME%\bin\ %EXAMPLE_HOME%\conf\ %EXAMPLE_HOME%\lang\ %EXAMPLE_HOME%\lib\ %EXAMPLE_HOME%\mylib\ %EXAMPLE_HOME%\logs\
如下:lang目录是存放支持其他语言的语言包，一般用不到
2. 然后将我们下载的wrapper目录下的文件拷贝到我们上面建的目录:
%WRAPPER_HOME%\bin\wrapper.exe -> %EXAMPLE_HOME%\bin\wrapper.exe %WRAPPER_HOME%\lib\wrapper.jar -> %EXAMPLE_HOME%\lib\wrapper.jar
%WRAPPER_HOME%\lib\wrapper.dll -> %EXAMPLE_HOME%\lib\wrapper.dll
%WRAPPER_HOME%\conf\wrapper.conf -> %EXAMPLE_HOME%\conf\wrapper.conf
将自己程序打成的包以及自己程序依赖的包放到mylib:
3.修改配置文件 %EXAMPLE_HOME%\conf\wrapper.conf
#java.exe所在位置
wrapper.java.command=C:\Program Files\Java\jdk1.7.0_80\bin\java.exe
#日志级别
wrapper.java.command.loglevel=INFO
#主类入口，第一个mainClass是固定写法，是wrapper自带的，不可以写成自己的，如果写成自己的入口程序自己的程序需要实现wrapper的WrapperListener接口
#parameter.1是自己的主程序入口所在类(从包名开始)
wrapper.java.mainclass=org.tanukisoftware.wrapper.WrapperSimpleApp
wrapper.app.parameter.1=MapTest
#依赖的包，第一个是wrapper包，第二个是自己打的包以及程序依赖包
wrapper.java.classpath.1=../lib/wrapper.jar
wrapper.java.classpath.2=../mylib/*.jar
#固定写法，依赖的wrapper的包
wrapper.java.library.path.1=../lib
#日志文件位置
wrapper.logfile=../logs/wrapper.log
#服务名称以及描述信息
wrapper.console.title=Hello World Server
wrapper.name=helloworldserver
wrapper.displayname=Hello World Server
wrapper.description=Hello World Server
注意:
(1)上面的主类实际是:org.tanukisoftware.wrapper.WrapperSimpleApp，此类实现了WrapperListener接口。所以如果我们用此参数定义自己的主函数需要实现此接口。实现此接口就不用wrapper.app.parameter.1作为函数参数了
(2)wrapper.app.parameter.1=MapTest 是将Maptest作为参数传入到主函数中，也就是依次作为类WrapperSimpleApp的main(String[] args)函数的参数。源码如下:
(3)不能一次传多个参数，生效的始终是第一个参数，传第二个参数也不会生效。传第二个参数或者多个参数是作为MapTest的主函数的参数。

4.开始注册服务以及测试
(1)控制台测试
C:\Users\Administrator>cd C:\Users\Administrator\Desktop\SW C:\Users\Administrator\Desktop\SW>bin\wrapper.exe -c ..\conf\wrapper.conf wrapper | --> Wrapper Started as Console wrapper | Java Service Wrapper Community Edition 32-bit 3.5.25 wrapper | Copyright (C) 1999-2014 Tanuki Software, Ltd.

(2)将程序注册为服务:
bin\wrapper.exe -i ..\conf\wrapper.conf
结果：
wrapper | Hello World Server service installed.
(3)启动服务:
net start helloworld
或者:
bin\wrapper.exe -t ..\conf\wrapper.conf
启动之后我们回看到程序输出在logs\wrapper.log文件内:
(4)停止服务
net stop helloword
或者
bin\wrapper.exe -p ..\conf\wrapper.conf
(5)删除服务
sc delete helloword
或者
bin\wrapper.exe -r ..\conf\wrapper.conf
-----------上面是在系统有Java环境的情况下的设置，现在假设我们不存在Java运行环境，也就是没有JRE与JDK:-------------
(1)拷贝java安装目录下的JRE（包含bin目录和相关lib）目录到上面的目录%EXAMPLE_HOME%,如下:
jre目录下:
(2)修改配置文件，利用我们上面的jre目录下的jar包和bin\java.exe
#java.exe所在位置
wrapper.java.command=../jre/bin/java.exe
#日志级别
wrapper.java.command.loglevel=INFO
#主类入口，第一个mainClass是固定写法，是wrapper自带的，不可以写成自己的，如果写成自己的入口程序自己的程序需要实现wrapper的WrapperListener接口
wrapper.java.mainclass=org.tanukisoftware.wrapper.WrapperSimpleApp
#parameter.1是自己的主程序入口所在类(从包名开始)
wrapper.app.parameter.1=MapTest
#依赖的包，第一个是wrapper包，第二个是自己打的包以及程序依赖包
wrapper.java.classpath.1=../jre/lib/*.jar
wrapper.java.classpath.2=../lib/wrapper.jar
wrapper.java.classpath.3=../mylib/*.jar
#固定写法，依赖的wrapper的包
wrapper.java.library.path.1=../lib
#日志文件位置
wrapper.logfile=../logs/wrapper.log
#服务名称以及描述信息
wrapper.console.title=Hello World Server
wrapper.name=helloworldserver
wrapper.displayname=Hello World Server
wrapper.description=Hello World Server
(3)安装服务与测试与上面一样:

为了验证我们的服务是使用的jre目录下的JDK，我们可以将jre目录删掉进行测试，或者是将配置文件中jre\lib的引入注释掉进行测试。
现在我们将jre目录删掉，启动服务报错如下:
在wrapper.log中查看到的日志文件如下:
至此我们实现了简单的有JRE与无JRE两种情况的注册服务，实际没有JRE环境的时候我们只需要将我们的JRE附到目录中并且在wrapper.conf中指明所在路径即可。
补充1.:上面配置会导致JVM不断重启，需要加JVM参数以及设置，同时设置服务开机启动:并且使用一变量记住我们的项目路径；修改wrapper.conf并且删掉服务重新添加：
#定义了一个根路径，注意set和.之间没有空格，下面就可以用%basePath%取此变量
set.basePath=C:\Users\liqiang\Desktop\xxx\SW
#java.exe所在位置
wrapper.java.command=%basePath%/jre/bin/java.exe

删除重装服务:

如果我们想检测JVM参数可以用jps+jmap监测即可:
C:\Users\liqiang>jps 505668 Jps 504320 WrapperSimpleApp 487768 C:\Users\liqiang>jmap -heap 504320 Attaching to process ID 504320, please wait... Debugger attached successfully.

补充2:我们可以用上面的service wrapper的bin包中的bat文件进行安装服务: (将上面安下载解压后的wrapper-windows-x86-32-3.5.25\bin中的文件复制到我们的%EXAMPLE_HOME%\bin目录下)
我们只需要点击上面的bat文件即可实现上面的操作。
*************************
我已经将我的一个例子上传到我的服务器，下载地址:http://qiaoliqiang.cn/fileDown/serviceWrapperExample.zip
下载解压之后只需要将自己程序打的包以及依赖包放到mylib目录下，修改conf\wrapper.conf文件中下面两处
set.basePath=C:\Users\liqiang\Desktop\xxx\SW #替换为自己的目录
#parameter.1是自己的主程序入口所在类(从包名开始)
wrapper.app.parameter.1=MapTest #替换为自己的程序入口
然后点击bin目录的TestWrapper.bat测试即可
**************************
3.将log4j日志与servicewrapper日志进行整合
开发环境下一切正常。用JavaServiceWrapper部署到服务器上之后，发现log文件没有生成。同时在wrapper的log中有两行log4j的错误信息：
log4j:WARN No appenders could be found for logger (com.xxxxx).
log4j:WARN Please initialize the log4j system properly.
查找了一番，最后发现在wrapper.conf中加入一行，硬性指明log4j的配置文件就OK了：
wrapper.java.additional.1=-Dlog4j.configuration=file:../conf/log4j.properties
StackOverflow上有人回答类似的问题，用的方法是
wrapper.java.additional.1=-Dlog4j.configuration=../config/log4j.properties
但是我这样测试没成功。不知道是不是和版本有关。
(1) 测试代码:
package serviceWrapper; import org.slf4j.Logger; import org.slf4j.LoggerFactory; public class MapTest { private static Logger log = LoggerFactory.getLogger(MapTest.class); public static void main(String[] args) { int times = 0; while (true) { try { Thread.sleep(3 * 1000); } catch (InterruptedException e) { } try { int i = 1 / 0; } catch (Exception e) { log.error("error[{}] by / 0 ", times++, e); } } } }
(2)测试代码打成包并一起复制到mylib目录下:
依赖的jar包以及自己打的包:
(3)目录结构:
(4)bin目录与上面一样，jre也一样，lang也一样，lib也一样，logs也一样，mylib在(2)中换过，将log4j.properties文件复制到conf目录下:
log4j.properties文件:
log4j.rootLogger=info,A,B

(5)修改wrapper.conf文件:
#定义了一个根路径，注意set和.之间没有空格，下面就可以用%basePath%取此变量
set.basePath=C:\Users\liqiang\Desktop\logTest
#java.exe所在位置
wrapper.java.command=%basePath%/jre/bin/java.exe
#主类入口，第一个mainClass是固定写法，是wrapper自带的，不可以写成自己的，如果写成自己的入口程序自己的程序需要实现wrapper的WrapperListener接口
wrapper.java.mainclass=org.tanukisoftware.wrapper.WrapperSimpleApp
#parameter.1是自己的主程序入口所在类(从包名开始)，生效的始终是第一个参数
wrapper.app.parameter.1=serviceWrapper.MapTest
wrapper.app.parameter.2=MapTest
# Java Classpath配置，必须从序号"1"开始，添加新的jar包后序号递增
#JRE的包
wrapper.java.classpath.1=../jre/lib/*.jar
#wrapper.jar
wrapper.java.classpath.2=../lib/wrapper.jar
#自己的包以及程序依赖包
wrapper.java.classpath.3=../mylib/*.jar
#固定写法，依赖的wrapper的包
wrapper.java.library.path.1=%basePath%/lib
#日志文件位置
wrapper.logfile=../logs/wrapper.log
# 控制台信息输出格式
wrapper.console.format=PM
# 日志文件输出格式
wrapper.logfile.format=LPTM
# 日志文件日志级别
wrapper.logfile.loglevel=INFO
#服务名称以及描述信息
wrapper.console.title=Hello World Server
wrapper.name=helloworldserver
wrapper.displayname=Hello World Server
wrapper.description=Hello World Server
wrapper.jmx=false
wrapper.on_exit.0=SHUTDOWN
wrapper.on_exit.default=RESTART
wrapper.ntservice.interactive = true
#服务开机启动
wrapper.ntservice.starttype=AUTO_START
wrapper.tray = true
wrapper.java.monitor.deadlock = true
wrapper.java.monitor.heap = true
wrapper.java.monitor.gc.restart = true
# Java Heap 初始化大小(单位：MB)
wrapper.java.initmemory=128
# Java Heap 最大值(单位：MB)
wrapper.java.maxmemory=128
# 32/64位选择，true为自动选择
wrapper.java.additional.auto_bits=TRUE
#附加参数即为java命令可选参数，如下所示：
#设置log4J日志文件位置
wrapper.java.additional.1=-Dlog4j.configuration=file:../conf/log4j.properties
注意: 附加参数 wrapper.java.additional.1 即为java命令可选参数(可用于指定JVM参数与指定垃圾收集器组合)，如下所示：
C:\Users\liqiang>java 用法: java [-options] class [args...] (执行类) 或 java [-options] -jar jarfile [args...] (执行 jar 文件) 其中选项包括: -d32 使用 32 位数据模型 (如果可用) -d64 使用 64 位数据模型 (如果可用) -server 选择 "server" VM -hotspot 是 "server" VM 的同义词 [已过时] 默认 VM 是 server. -cp <目录和 zip/jar 文件的类搜索路径> -classpath <目录和 zip/jar 文件的类搜索路径> 用 ; 分隔的目录, JAR 档案 和 ZIP 档案列表, 用于搜索类文件。 -D<名称>=<值> 设置系统属性 -verbose:[class|gc|jni] 启用详细输出 -version 输出产品版本并退出 -version:<值> 需要指定的版本才能运行 -showversion 输出产品版本并继续 -jre-restrict-search | -no-jre-restrict-search 在版本搜索中包括/排除用户专用 JRE -? -help 输出此帮助消息 -X 输出非标准选项的帮助 -ea[:<packagename>...|:<classname>] -enableassertions[:<packagename>...|:<classname>] 按指定的粒度启用断言 -da[:<packagename>...|:<classname>] -disableassertions[:<packagename>...|:<classname>] 禁用具有指定粒度的断言 -esa | -enablesystemassertions 启用系统断言 -dsa | -disablesystemassertions 禁用系统断言 -agentlib:<libname>[=<选项>] 加载本机代理库 <libname>, 例如 -agentlib:hprof 另请参阅 -agentlib:jdwp=help 和 -agentlib:hprof=help -agentpath:<pathname>[=<选项>] 按完整路径名加载本机代理库 -javaagent:<jarpath>[=<选项>] 加载 Java 编程语言代理, 请参阅 java.lang.instrument -splash:<imagepath> 使用指定的图像显示启动屏幕 有关详细信息, 请参阅 http://www.oracle.com/technetwork/java/javase/documentation
(6)点击bin目录下的TestWrapper.bat测试控制台:
logs\wrapper.log文件内容如下:
E:\test.log文件内容如下:
log4j生成的日志文件与wrapper.logs文件的内容几乎一样，只是格式不一样。
至此完成与log4j的整合，其实与log4j整合也简单，就是在配置文件下面加一行引入log4j.properties文件的位置
wrapper.java.additional.1=-Dlog4j.configuration=file:../conf/log4j.properties
4.将tomcat注册为服务:设置tomcat服务开机启动，还是在没有JRE的环境下进行:(公司集成部署系统可以采用这种方式)
1.新建一目录，解压一个全新的tomcat，在%TOMCAT%目录下新建一个servicewrapper目录:
2.将自己的项目解压之后放在webapps目录下(这里采用目录解压部署，参考:https://www.cnblogs.com/qlqwjy/p/9478649.html)
3.与上面部署一样将所需要的文件拷贝到servicewrapper目录下:
bin目录是启动服务的bat文件和wrapper.exe文件，conf是wrapper.conf文件，jre是拷贝的jre环境，lang是空目录，lib是wrapper.jar和wrapper.dll文件，logs用于存放wrapper.log文件，mylib可以存放自己以及第三方jar包(不过web项目用不到这个)。
4.修改wrapper.conf文件的配置:(重要)
#定义了一个根路径，注意set和.之间没有空格，下面就可以用%basePath%取此变量
set.basePath=C:\Users\liqiang\Desktop\n2\tomcat\apache-tomcat-7.0.72
#java.exe所在位置
wrapper.java.command=%basePath%/servicewrapper/jre/bin/java.exe
#日志级别
wrapper.java.command.loglevel=INFO
#依赖的包，第一个是wrapper包，第二个是自己打的包以及程序依赖包
#jre的lb路径
wrapper.java.classpath.1=%basePath%/servicewrapper/jre/lib/*.jar
#wrapper.jar路径
wrapper.java.classpath.2=%basePath%/servicewrapper/lib/wrapper.jar
#自己的依赖jar包
wrapper.java.classpath.3=%basePath%/servicewrapper/mylib/*.jar
#tomcat依赖的包(tomcat启动类在这个包中)
wrapper.java.classpath.4 = %basePath%/bin/bootstrap.jar
wrapper.java.classpath.5 = %basePath%/bin/tomcat-juli.jar
#Wrapper集成主类。有4种集成方式，适合tomcat这样启动使用一个类，
#停止使用另一个类的应用的是WrapperStartStopApp类
wrapper.java.mainclass=org.tanukisoftware.wrapper.WrapperStartStopApp
#tomcat应用参数，无需修改(第一个参数是tomcat的启动类)
wrapper.app.parameter.1=org.apache.catalina.startup.Bootstrap
wrapper.app.parameter.2=1
wrapper.app.parameter.3=start
wrapper.app.parameter.4=org.apache.catalina.startup.Bootstrap
wrapper.app.parameter.5=TRUE
wrapper.app.parameter.6=1
wrapper.app.parameter.7=stop
wrapper.working.dir = %basePath%/bin
#固定写法，依赖的wrapper的包
wrapper.java.library.path.1=../lib
#wrapper.log日志文件位置
wrapper.logfile=%basePath%/servicewrapper/logs/wrapper.log
#服务名称以及描述信息
wrapper.console.title=Exam Server
wrapper.name=examservice
wrapper.displayname=Exam Server
wrapper.description=Exam Server
#Tomcat的固定参数(一般不用修改)
wrapper.java.additional.1=-Djava.util.logging.config.file=%basePath%/conf/logging.properties
wrapper.java.additional.2 = -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager
wrapper.java.additional.3 = -Djava.endorsed.dirs=%basePath%/endorsed -Dcatalina.base=%basePath% -Dcatalina.home=%basePath%
wrapper.java.additional.4 = -Djava.io.tmpdir=%basePath%/temp
wrapper.java.additional.5 = -Djava.net.preferIPv4Stack=true
wrapper.java.additional.6 = -XX:MaxNewSize=256m
wrapper.java.additional.7 = -XX:MaxPermSize=256m
wrapper.java.additional.8 = -XX:-UseGCOverheadLimit
wrapper.java.additional.9 = -Dcom.sun.management.jmxremote
wrapper.jmx=false
wrapper.on_exit.0=SHUTDOWN
wrapper.on_exit.default=RESTART
wrapper.ntservice.interactive = true
#服务开机启动
wrapper.ntservice.starttype=AUTO_START
wrapper.tray = true
#监测JVM死锁
wrapper.java.monitor.deadlock = true
wrapper.java.monitor.heap = true
wrapper.java.monitor.gc.restart = true
# Java Heap 初始化大小(单位：MB)
wrapper.java.initmemory=1024
# Java Heap 最大值(单位：MB)
wrapper.java.maxmemory=1024
5.注册为服务:
C:\Users\liqiang\Desktop\n2\tomcat\apache-tomcat-7.0.72\servicewrapper>bin\wrapper.exe -i ..\conf\wrapper.conf wrapperm | Exam Server service installed. C:\Users\liqiang\Desktop\n2\tomcat\apache-tomcat-7.0.72\servicewrapper>sc qc examservice [SC] QueryServiceConfig 成功 SERVICE_NAME: examservice TYPE : 110 WIN32_OWN_PROCESS (interactive) START_TYPE : 2 AUTO_START ERROR_CONTROL : 1 NORMAL BINARY_PATH_NAME : C:\Users\liqiang\Desktop\n2\tomcat\apache-tomcat-7.0.72\servicewrapper\bin\wrapper.exe -s C :\Users\liqiang\Desktop\n2\tomcat\apache-tomcat-7.0.72\servicewrapper\conf\wrapper.conf wrapper.console.flush=true wrapp er.internal.namedpipe=1139632464 LOAD_ORDER_GROUP : TAG : 0 DISPLAY_NAME : Exam Server DEPENDENCIES : SERVICE_START_NAME : LocalSystem C:\Users\liqiang\Desktop\n2\tomcat\apache-tomcat-7.0.72\servicewrapper>
6.启动服务并进行日志查看:
由于项目中使用了log4j，所以现在可以从两个地方查看log日志。第一个是log4j指定的日志的输出的位置，第二个是wrapper.logs文件。
7.监测Tomcat的参数信息:
可以jps+jmap进行查看(前提是安装JDK)，如果没有安装JDK可以利用tomcat自带的manager项目进行监测(参考:https://www.cnblogs.com/qlqwjy/p/8037392.html)。如果需要对参数进行优化，只需要修改上面wrapper.conf文件即可。
总结:
上面还可以进行大量的优化，比如讲一些不用的文件删掉，将多个lib目录进行合并；
至此完成了tomcat注册为web服务，项目中一般使用这种方式进行部署项目，而且mysql可以采用集成部署集成到系统中，到时候系统上线的时候只用一个压缩包传到服务器，避免大量的下载tomcat、mysql等以及大量的配置。我上个项目上线也确实是通过安装JDK、mysql、tomcat等进行部署安装的，采用这种集成的方式都不用安装JDK等软件，简化部署。
5.linux环境下的注册为服务

补充:wrapper安装的服务不能正常启动
报错Unable to execute Java command. 系统找不到指定的文件。
原因是找不到Java命令，解决办法就是修改wrapper.conf将java路径设为绝对路径，如下:
# Path to JVM executable. By default it must be available in PATH. # Can be an absolute path, for example: #wrapper.java.command=/path/to/my/jdk/bin/java wrapper.java.command=C:\Program Files\Java\jdk1.8.0_121\bin\java.exe
