Hi brother, because you commented out this code, I spent a day troubleshooting the problem that the jar class could not be loaded.
It is required and cannot be commented out. I have a problem when using the springboot jar package. Please be sure to test it.
Also, it cannot be commented, please modify it.

The generated method name is legal and contains'/'.

Find this place through code tracing

Please delete '$/' as I resolved the issue of illegal method names by deleting them

Additionally, there are issues with this code:

Builder. append (CHARS [random. nextInt (CHARS. length)]);
When random. nextInt (CHARS. length) returns a range of 1-10, a method name that starts with a number is also illegal

I don't understand why configuring this would cause this error

Hello,

when I do the command to build the project,

I have errors in the compileJava level,

how much java is needed? because I have java 8

Thank you for your reply, Good day

You can see that the method name is illegal

Here are my modifications

while (builder.length() < len) {
int nextInt = random.nextInt(CHARS.length);
if (builder.length() == 0 && nextInt < 10) {
continue;
}
builder.append(CHARS[nextInt]);
}

Test the result a thousand times without a string starting with a number

I hope you can adopt my method, or if you have any good modifications, I can also learn from it.
