Java-d command-line arguments

we will use MVN to launch an application, such as the following command line:

1. maven_opts= "-xx:permsize=256m-xx:maxpermsize=512m" mvn spring-boot:run-drun.jvmarguments= "-XDEBUG-XRUNJDWP: transport=dt_socket,server=y,suspend=n,address=8000 "

Let's take a look at the meaning of these command lines .

-dxxxx is the syntax for Java run parameters

The role is to configure some environment variables, what specific parameters , parameters have what effect, and you use the actual environment, the project structure are related
Yes, let the program know what Log_path stands for, and how the program is used, that's the procedure.

System.getproperty ("PropertyName") such as yours is System.getproperty ("Log_path") can get
The main function of Java has the string[] parameter. This parameter can be passed through-D.
Log_path this will be stored in the System.getproperty (),
Property is inherited from Hashtable. can be obtained by System.getproperty ("Log_path").

Java Startup Parameters

Java startup parameters are divided into three categories;
The first is the standard parameter (-), all JVM implementations must implement the functions of these parameters, and backward compatibility;
The second is the non-standard parameter (-x), the default JVM implements the functions of these parameters, but does not guarantee that all JVM implementations are satisfied, and does not guarantee backward compatibility;
its third is non- Stable parameters (-XX), such parameters of each JVM implementation will be different, in the future may be canceled at any time, need to use cautiously;
