Java joins Windows System Service (Java service wrapper)

It is necessary to develop a distributed system for work, but there is a problem in server setup. Because Java has never been related to the operating system. It is not so easy to add to the system service. If a user is logged out, the Java W process will also be shut down accordingly. There are many ways to add tomcat or IIS to the backend service of the server. After trying, we foundJava service wrapperTo achieve relevant results.

First download the latest versionJava service wrapper http://wrapper.tanukisoftware.org/doc/english/download.jsp.

After decompression, not every file must be used. First, we create a folder to store the system process.

The approximate structure is as follows:

 

 

The main files in the bin directory are: installnb-nt.batw.nb.batw.uninstallnb-nt.batw.wrapper.exe

The main files in the conf directory are: wrapper. conf

Main files in the lib directory are: wrapper. dll, wrapper. jar, and wrappertest. jar.

Main files in the logs directory are: Nb. Log (you can change the name)

All these files can be found in the ZIP file you downloaded. They are required.

 

Then paste the class of your entire project to the bin directory (I am not storing jar files, for the sake of convenience of updating). Some XML files used as the configuration must also be placed in this location, then the class can be read directly.

 

 

The main method of my program is in server. dbdaoserver. Class.

 

Then pay attention to the content in/CONF/wrapper. conf.

Configure the JRE location:

# Java application
Wrapper. java. Command = ../jre1.7.0/bin/Java

 

Configure the class Space Location

Wrapper. java. classpath.1 = ../lib/wrapper. Jar
Wrapper. java. classpath.2 =.../bin /.

 

Configure the Lib path

Wrapper. java. Library. path.1 = ../lib

 

Configure the BAT file to be started (for testing)

Wrapper. java. additional.1 =-dprogram. Name = Nb. bat

 

Configure initial memory and maximum memory

# Initial Java heap size (in MB)
# Wrapper. java. initmemory = 3

# Maximum Java heap size (in MB)
# Wrapper. java. maxmemory = 64

 

Configure the main class of the service (key)

# Application parameters. Add parameters as needed starting from 1
Wrapper. App. parameter.1 = server. dbdaoserver

 

Configuration Console (no modification required)

# Format of output for the console. (See docs for formats)
Wrapper. Console. format = PM

# Log level for console output. (See docs for log levels)
Wrapper. Console. loglevel = info

Configure the running record file

# Log file to use for wrapper output logging.
Wrapper. logfile = ../logs/Nb. Log

# Format of output for the log file. (See docs for formats)
Wrapper. logfile. format = lptm

# Log level for log file output. (See docs for log levels)
Wrapper. logfile. loglevel = info

 

# Maximum size that the log file will be allowed to grow to before
# The log is rolled. size is specified in bytes. The default value
# Of 0, disables log rolling. May abbreviate with the 'K' (Kb) or
# 'M' (MB) Suffix. For example: 10 m = 10 megabytes.
Wrapper. logfile. maxsize = 0

# Maximum number of rolled log files which will be allowed before old
# Files are deleted. The default value of 0 implies no limit.
Wrapper. logfile. maxfiles = 0

# Log level for sys/event log output. (See docs for log levels)
Wrapper. syslog. loglevel = none

 

Configure System Service name

# Name of the service
Wrapper. ntservice. Name = rmiservice

 

Configure the name displayed by the System Service

# Display name of the service
Wrapper. ntservice. displayname = rmiservice

 

Configure System Service Description

# Description of the service
Wrapper. ntservice. Description = rmiservice

Configure the System Service Startup Mode

# Mode in which the service is installed. auto_start or demand_start
Wrapper. ntservice. starttype = auto_start

If any of the above processes are incorrect, I hope to correct them.
