问题:

Can you do loops in code templates, e.g I want to print all the fields in a class. Is there a template for that?

回答1:

Assuming you're talking about Java > Editor > Templates a reference (maybe outdated) is here

This SO question useful-eclipse-java-code-templates containes some examples.

To iterate over class members using a toString() style generator you may find this useful: toString() Generator: Format Templates

回答2:

Eclipse can generate toString(), which includes a print out of all fields and their string values, if that's what you are after.

Since I didn't find what I was looking for, I put it in my plugin. It supports variations. If you have class called Company with fields companyName, companyType, etc. it will generate print statements as shown below if you select logger.debug variation :

if (logger.isDebugEnabled()) {
    logger.debug("Company Name " + company.getCompanyName());
    logger.debug("Company Type " + company.getCompanyType());
}
