Common Bean Utils

[Fisher Daniel]

Dear all,
I am building web application using Struts.
I want to copy the value of a form into a value object using Bean Utils.
Does BeanUtils.copyProperties method include trimming process for every value of the form?
Or do I have to do trimming process manually before I use BeanUtils.copyProperties method?

thanks
daniel

you must create trim() process before call PropertyUtils.copyProperties(). because this method not have trim() process.

[Paul Strachan]

you could trim() in your value object setter method.
eg.

public void setName(String name) {
this.name = ((name == null) ? null : name.trim());
}

do this for all your String attribute

you can use StringUtils.trim() to reduce your code lines.

yep, its good point.

StringUtils.trim( ) delegates to the trim( ) function on String and gracefully handles null. When you pass a null to StringUtils.trim( ), it returns a null.

And you can use trimming to NULL of StringUtils ::

Example

 public void doGet(HttpServletRequest request, HttpServletResponse response)
 
    throws IOException, ServletException {
 

 
    String companyName = 
 
        StringUtils.trimToNull( request.getParameter("companyName") );
 
    if( companyName != null ) {
 
        response.getWriter( ).write( "You supplied a company name!" );
 
    }
 
}
