如何在蚀中为可变对象生成获取器和设置器？

Question

one of the sonar issue that I recently found was that "Malicious code vulnerability - May expose internal representation by incorporating reference to mutable object"

For example ideally Eclipse should generate setter for date like following

public void setBillDate(Date billDate) {
    this.billDate = (Date)billDate.clone();
}

How can I force Eclipse to generate code like this?

Answer 1

Window -> Preferences -> Java -> Code Style -> Code Templates 

Enable project specific settings

You'll see "Setter Body", Edit:

${field} = ${param};

The code you need might be written as

try {
        ${field} = ${param}.getClass().cast( ${param}.clone() );
} catch( CloneNotSupportedException cnse ){
     // whatever
}

I admit that I don't know whether there is a template variable for the parameter class. Investigating...
