I am trying to get one simple spring application running but getting following exception:

javax.servlet.ServletException: javax.servlet.jsp.JspTagException: No message found under code 'label.firstname' for locale 'en_US'.

Steps to get issue resolved:

  1. Place messages_en.properties files in src/main/resource folder only
  2. Make sure name of file is correct as messages_en.properties and not message_en.properties
  3. When you do maven build using mvn clean install messages_en.properties file will appear in target/projectname/WEB-INF/classes/messages.properties
  4. Check in spring-servlet.xml(name may vary) and use classpath:messages as basename in messageSource

and it should work as it resolved my issue.

<bean id="messageSource"
    class="org.springframework.context.support.ReloadableResourceBundleMessageSource">
    <property name="basename" value="classpath:messages" />
    <property name="defaultEncoding" value="UTF-8" />
</bean>

回答1:

Your MessageSource bean definition is a little confusing. Typically the basename is the prefix of the filename (minus .properties) you want to use for the message resolution, which Spring and the JDK ResourceBundle class will append the language and/or country abbreviation to.

<bean id="messageSource"
    class="org.springframework.context.support.ReloadableResourceBundleMessageSource">
    <property name="basename" value="WEB-INF/message_en.properties/Message" />
    <property name="defaultEncoding" value="UTF-8" />
</bean>

For example, if you intended to have resource files like messages.properties, messages_es.properties, messages_de.properties you would specify a basename of WEB-INF/messages.

What is the actual name of your message bundle file(s)?



回答2:

I had the same problem, the solution was:

  1. Place the messages.properties file in the source folder src/main/resources

  2. Define the Bean as follow:

    <bean id="messageSource"
             class="org.springframework.context.support.ReloadableResourceBundleMessageSource">
    <property name="basename" value="classpath:messages" />
    <property name="defaultEncoding" value="UTF-8" />
    

You see that I put in property the same name of the file messages.properties without .properties

that was the problem ^^



回答3:

You have to add the "resources" folder to "Web Deployment Assembly". After that replace "classpath:messages" to only "messages". The last change you need to make is clean your projects.

example:

<bean id="messageSource"
    class="org.springframework.context.support.ReloadableResourceBundleMessageSource">
    <property name="basename" value="messages" />
    <property name="defaultEncoding" value="UTF-8"/>
</bean>

That will suffice. :)



回答4:

An important consideration is that, in order to auto reload, properties file should not be in the classpath. Servers usually cache the properties so if its in the classes folder, its not really effective. Per Spring docs, in case of classpath:messages, cachedSeconds other than -1 will not have any effect.



回答5:

Better late than never. I had the same problem. Here is how I solved it. My file name was :

messages_fr.properties

for france because its a french Spring Tutotrial. But, i reside in The Nederlands. So i tried to rename it to

messages_nl.properties

and it works. Not sure if this is a long term workaround but we ll see.



回答6:

To anybody else who will face the issue.

Besides all the answers, make sure you let the .jsp file be processed by Spring Framework. If .jsp is accessed directly, spring tags won't be processed, and you'll see the exact same error. Simply put, expose the .jsps through the controllers.



回答7:

I had the same problem but I simply left it as messages_properties and it solved the issue
