  1. POHow to prevent parameter binding from interpreting commas in Spring 3.0.5?
    text
    copied!<p>Consider the following controller method:</p> <pre><code>@RequestMapping(value = "/test", method = RequestMethod.GET) public void test(@RequestParam(value = "fq", required = false) String[] filterQuery) { logger.debug(fq = " + StringUtils.join(filterQuery, "|")); } </code></pre> <p>Here is the output for different <code>fq</code> combinations:</p> <ol> <li><code>/test?fq=foo</code> results in <code>fq = foo</code> </li> <li><code>/test?fq=foo&amp;fq=bar</code> results in <code>fq = foo|bar</code> </li> <li><code>/test?fq=foo,bar</code> results in <code>fq = foo|bar</code> </li> <li><code>/test?fq=foo,bar&amp;fq=bash</code> results in <code>fq = foo,bar|bash</code> </li> <li><code>/test?fq=foo,bar&amp;fq=</code> results in <code>fq = foo,bar|</code></li> </ol> <p>Example 3 is the problem. I expect (want/need) it to output <code>fq = foo,bar</code>.</p> <p>I've tried escaping the comma with <code>\</code> and using <code>%3C</code> but niether work. </p> <p>If I look at the <code>HttpServletRequest</code> object's version:</p> <pre><code>String[] fqs = request.getParameterValues("fq"); logger.debug(fqs = " + StringUtils.join(fqs, "|")); </code></pre> <p>It prints the expected output: <code>fqs = foo,bar</code>. So the "problem" is with the Spring data binding.</p> <p>I could by-pass Spring's binding and use <code>HttpServletRequest</code> but I really don't want to as I'm using a <strong>backing bean</strong> in my real code (same thing is happening) and don't wish to re-implement the binding functionality. I'm hoping someone can provide a simple way of preventing this behavior via escaping or some other mechanism.</p> <p>TIA</p> <p><strong>UPDATE:</strong> I posted this Q on Twitter and got a reply saying <strong>the expected output appears with Spring 3.0.4.RELEASE</strong>. I've now confirmed this is the case and thus is a temporary fix. I'll go ahead and log this as a bug on the Spring JIRA system. If anyone can provide a work around or fix with 3.0.5, I'll accept their answer.</p>
