Easy Java Bean toString() using BeanUtils
I often want to have a String description of my beans for debugging or logging purposes, but hate having to manually concatenate the fields in my class to create a toString() method. This code snippet using Apache Commons (a.k.a. Jakarta Commons) is very helpful for just such occasions:
public String toString() {
try {
return BeanUtils.describe(this).toString();
} catch (Exception e) {
Logger.getLogger(this.getClass()).error("Error converting object to String", e);
}
return super.toString();
}

I think a much easier and better solution would be simply to use the Commons Lang ReflectionToStringBuilder class:
for example:
public String toString() {
return ReflectionToStringBuilder.toString(this, ToStringStyle.MULTI_LINE_STYLE);
}
