CodePudding user response:

Write an Agent class, realize premain method, if you say the class is ray Class1,

 import ray. Class1; 
Public class Agent1 {
Public static void premain (String agentArgs) {
If (agentArgs. Equals (" t ")) 
Class1. In_dev_mode=true; 
Else if (agentArgs equals (" f ")) 
Class1. In_dev_mode=false; 
} 
}

Compile the Agent class

 javac - cp Class1. Jar Agent1. Java

Write the MANIFEST. MF file

 Premain - Class: Agent1

Packaging

 jar of CMF MANIFEST. MF Agent1. Jar Agent1. Class

The

 Java - javaagent: Agent1. Jar=t - jar Class1. Jar
