 1 | # HookAgent
 2 | 
 3 | A simple Java Agent template with javassist support.
 4 | 
 5 | Command line example:
 6 | ```shell
 7 | # pass hook arguments via agentArgs.
 8 | java -Xmx16G --add-opens java.base/java.lang=ALL-UNNAMED -Xverify:none \
 9 |      -javaagent:HookAgent.jar=className=com.example.Foo;methodName=bar;methodImplFile=hook.js \
10 |      target.jar
11 | # or pass hook arguments via Properties.
12 | java -Xmx16G --add-opens java.base/java.lang=ALL-UNNAMED -Xverify:none \
13 |      -javaagent:HookAgent.jar \
14 |      -Dhook.className=com.example.Foo \
15 |      -Dhook.methodName=bar \
16 |      -Dhook.methodImplFile=hook.js \
17 |      target.jar
18 | ```
19 | 
20 | The `hook.js` example:
21 | ```js
22 | {
23 |     System.out.println("[agent-hook] skip check: " + new java.util.Date());
24 |     return 0;
