Spring 3 - Accessing messages.properties in jsp

Question

I am new using spring 3 and have been stuck for a while on this.

Do you know how can I access messages.properties from a jsp. For instance, in the controller I set a value to my model:

model.setError("user.not.found")

messages.properties:

user.not.found=Sorry, we haven't been able to found this user

and in the jsp I want to be able to do

${model.error}

and displaying "sorry...". However I always get "user.not.found" even if this works fine when I use the @Valid ..., bindingResult and then in the form.

Thanks,

Use <spring:message> from the spring taglib:

<spring:message code = "${model.error}" />

where taglib is imported as

<%@ taglib prefix = "spring" uri = "http://www.springframework.org/tags" %>

And here's the taglib reference: http://static.springsource.org/spring/docs/3.0.x/spring-framework-reference/html/spring.tld.html – Sean Patrick Floyd Feb 01 '11 at 15:53
Is possible to get message from messageSource without using tags, i mean some expression like ${msg['code']} ? – marioosh Apr 04 '11 at 06:11
@marioosh: I guess, there are no easy ways. – axtavt Apr 04 '11 at 08:33

You can use ${msg.getMessage('MSG_CODE')} in JSP, if you put message resolver into the Model(or ModelAndView) in the controller.

// In a controller class

...

@Autowired
private MessageResolver messageResolver;

...

@RequestMapping(value="/edit")
public ModelAndView getSomething(MyFormData formData,
                                 ModelAndView mv) {
    mv.setViewName("TARGET_VIEW");

    // Do some controller things...

    Map<String, Object> map = new HashMap<String, Object>();
    map.put("msg", messageResolver);

    mv.addAllObjects(map);

    return mv;
}

And in JSP, you can use ${msg.getMessage('MESSAGE_CODE')}. The big advantage of this approach is that you can use Message even inside the Spring Form Tags. <spring:message code="MESSAGE_CODE" /> can not be used inside the Spring Form Tags.

<form:select path="domainObj1.property1" cssClass="form-control">
    <form:option value="" label="--${msg.getMessage('L01006')}--" />
    <form:options items="${selection.selectionList}" itemValue="code" itemLabel="codeVal"/>
</form:select>

It is even better that you implement a custom Interceptor(specifically, the postHandle method) to put the messageResolver into the ModelAndView rather than you write the same code in all controllers.
