Leave it to the reader

About blogs , I have written it by hand , To put it bluntly, it means developing an application independently , Build your own server , Deploy 、 The process of launching and maintaining the project , Of course, because it's the first day , So for those who are unwilling to develop , I provide a portable way , Look at the renderings first , My Hexo Static blog sites , You can download it directly and build it quickly , Maintenance does not require a server , Just register Github, Be able to give simple commands and spend a few minutes using the comment system given by others for free 、 Just count the reading amount .

First, let's talk about the needs analysis of blog platform development ：

development tool ：

First you need a IDEA development tool , This is generally recognized and recommended as the best Java development tool
The second is JDK , current JDK Unlike 1.8 Previous version , Yes, there are two bags , The current version JDK Contains JRE（Java Runtime Environment）, namely Java Operating environment , Virtual machine environment ,JDK（Java Development Kit）,Kit It's a tool , That is, some api tool kit , For example, common java.util、java.math and java.io wait .

Environmental Science ：

Java Environmental Science , Configuration Java Environment variables of , The purpose is to be able to use Java Of bin library , To configure path To JDK_HOME_PATH Directory path
Tomcat Environmental Science , Is to run Java Containers required for the project , We often develop war The bag can be in tomcat Of webapp Start in , and jar package （springboot） It's built in tomcat The package , It will automatically put springboot Built in tomcat Go to start , The principle is the same .
Maven Environmental Science , The project will depend on a lot jar package , We need a software to manage , Of course, it's not impossible for you to manage it manually , Use maven There are two reasons for portability ： First of all , One click import dependency package , There is no need to consider downloading manually , second , Easy to manage multi modular and aggregation projects .

tomcat Container start close command ：

       
       # linux  In the environment 
       
       ./
       
       bin
       
       /
       
       startup
       
       .
       
       sh 
       
       #  start-up 
       
       ./
       
       bin
       
       /
       
       shutdown
       
       .
       
       sh 
       
       #  close 
       
       # windows  In the environment 
       
       .\
       
       bin\
       
       startup
       
       .
       
       bat 
       
       #  start-up 
       
       ..\
       
       bin\
       
       shutdown
       
       .
       
       bat

springboot Start the shutdown command ：

       
       java 
       
       -jar [ suffix .jar Project path ] 
       
       #  The foreground mode starts  fg
       
nohup java 
       
       -jar [ suffix .har Project path ] & 
       
       #  Background mode starts  bg
       
       #  Advanced 
       
       #  Be proficient  linux bash  The script command can also run the script to start with one click and output the log file to the custom path 
       
java 
       
       -jar [ suffix .har Project path ] > /dev/null & 
       
       #  This kind of log file is the startup log file , For example, the running log file needs to be configured in the configuration file 
       
       #  If the configuration information of the project is modified , We use the default constraint , That is, configure in a specified way 
       
       #  stay  jar  Package current directory creation  ./config Folder /application.properties file , Note that the command startup should be consistent with jar The package is the same as the directory 
       
       #  for example ：java -jar ./test.jar #  So in ./  The directory will be read  ./config/application.properties
       
       #  Another example is currently  /home/  Next 
       
       #  Use command  [[email protected] home]java -jar /home/fyupeng/test.jar  The configuration file read is in /home Under the 
       
       #  So it is necessary to  cd Go to the current directory 
       
       #  Or specify an external command to specify the location of the configuration file ,--spring.config.location=[ route ]
       
       #  In this way, I'm springboot1.5  Version successfully tried , stay  2.0  There is a problem with the above , Use the default constraint and you're done 
       
       #  Be careful ： project  jar  package   And  config/application.properties  Put it in a folder , When starting, start the folder

Other necessary configurations ：

Tomcat Log output encoding configuration ：

Because most people are Win Operating system development , The default system code is GBK, and tomcat The default log output is UTF-8, development tool Tomcat Also configure the output console According to the system , So you can do it cmd Windows and idea Bear's paw has both effects .

logging.properties

       
       #java.util.logging.ConsoleHandler.encoding = UTF-8
       
java.util.logging.ConsoleHandler.encoding = GBK
