Spring validations default messages

问题

I need to get the resolved error messages programmatically in the controller. The default validation message for typeMismatch errors are not populating from my messages.properties file. I have a form backing object where a field is an Integer. If I submit a string for that field I get:

Failed to convert property value of type 'java.lang.String' to required type 'java.lang.Integer' for property 'establishedYear'; nested exception is java.lang.NumberFormatException: For input string: "1995a"

as the default message in the ObjectError. Here's my controller that output it:

  @RequestMapping(method = RequestMethod.POST)
  public @ResponseBody FormJSONResponse postForm(@Valid ProfileEditCompanyForm profileEditCompanyForm, BindingResult result) throws Exception {    
    if (result.hasErrors()) {
      for (ObjectError objectError : result.getAllErrors()) {
        System.out.println(objectError.getDefaultMessage());  // THIS IS NOT MY MESSAGE, BUT SHOULD BE
      }
    }
    ... other stuff ...
  }

So I added a messages.properties to WEB-INF/classes with some test messages to see if I could override that default message:

typeMismatch.profileEditCompanyForm.establishedYear=test 1
typeMismatch.establishedYear=test 2
typeMismatch.java.lang.Integer=test 3
typeMismatch=test 4
profileEditCompanyForm.establishedYear=test 5
establishedYear=test 6

In my app-servlet.xml file I have:

<mvc:annotation-driven conversion-service="conversionService" validator="validator"/>

<bean id="messageSource" class="org.springframework.context.support.ResourceBundleMessageSource">
  <property name="basename" value="messages" />
</bean>

<bean id="validator" class="org.springframework.validation.beanvalidation.LocalValidatorFactoryBean">
  <property name="validationMessageSource" ref="messageSource"/>
</bean>

Why isn't it picking up any of my messages from my messages.properties file?

回答1:

Try this in you Spring context instead:

<bean id="messageSource"
    class="org.springframework.context.support.ReloadableResourceBundleMessageSource">
    <property name="basename" value="WEB-INF/classes/messages" />
</bean>

Then inside "WEB-INF/classes" folder create a file call: "messages.properties"

Take note for the content of "messages.properties" you have to provide it like this :

typeMismatch.pathValueInsideYourJSPform:input= Your Message

Hope this helps you !

here is a sample also

Try specifying the complete path and try

    <bean id="messageSource" class="org.springframework.context.support.ResourceBundleMessageSource">
      <property name="basename" value="WEB-INF/messages" />
    </bean>
