Using PropertyPlaceholderConfigurer for integer values

[fdurden]

Hi,

Is it possible to use the PropertyPlaceholderConfigurer or something else to externalize properties such as the "period" value in the <schedule> element into an external properties file? That period for instance is defined as an integer in the schema, so setting a string like "${pollPeriod}" does not pass validation. Thanks!

This is an interesting point - thanks for raising it!

We do need to consider this tradeoff between XSD validation and placeholder configuration.

See this jira entry for 3.0; looks like jurgen plans to loosen the validation.

Indeed. Could you please raise an issue in the Spring Integration JIRA? We can change the types to xsd:string for attributes that are placeholder candidates in RC1.

Thanks,
Mark

The JIRA issue is here: http://jira.springframework.org/browse/INT-302
(It is also duplicated: http://jira.springframework.org/browse/INT-359)

Please add any comments to the first issue (INT-302).

Hi. I've opened a similar thread in the Spring security forum for this issue. The Jira indicates this has been fixed but is is specific to the XSD for Spring integration?

This is something that has to be addressed for individual XSD files.
