How to show values from property file in JSP in a spring MVC app

Question

I'm setting my properties in app-servlet.xml with a bean like this:

    <bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
            <property name="location" value="/WEB-INF/my.properties"></property>
    </bean>

Most of the time I access the properties in my controllers or other classes like this:

@Value("${dbtype}")
public String dbType;

But what if I want to use a property in a JSP file and bypass the controller. Meaning I don't want the value type being passed from the controller to the JSP as a model attribute.

Is there a way to access properties directly in a jsp?

Spring config

<util:properties id="propertyConfigurer" 
                  location="classpath:yourPropertyFileClasspathHere "/>
<context:property-placeholder properties-ref="propertyConfigurer" />

jsp

<spring:eval expression="@propertyConfigurer.getProperty('propertyNameHere')" />

And you have to add spring taglib to page: <%@ taglib prefix="spring" uri="http://www.springframework.org/tags" %> – Imreking Jul 26 '19 at 13:38
worked for me using propertyConfigurer on newer versions of spring. – AwkDenver Jul 04 '20 at 03:50

What you can also do that doesn't tie you to looking up properties in a single property placeholder, or if you are using java config and just instantiating a PropertySourcesPlaceholderConfigurer is use the environment object:

<spring:eval expression="@environment.getProperty('application_builtBy')" />

<bean class="org.springframework.context.support.ReloadableResourceBundleMessageSource" 
    id="messageSource"
    p:basenames="WEB-INF/i18n/site"
    p:fallbackToSystemLocale="false"/>

Now this is your Properties File

site.name=Cool Bananas

And here goes your JSP

<%@ taglib uri="http://www.springframework.org/tags" prefix="spring" %>
<html>
  <head>
    <title><spring:message code="site.name"/></title>
  </head>
  <body>
  </body>
</html>

Thanks for specifying the tag library declaration. This is omitted way too often. – baraber Sep 25 '17 at 14:34

In context just do this:

<util:properties 
    id="propertyConfigurer"
    location="classpath:yourPropertyFileClasspathHere"
/>
<context:property-placeholder properties-ref="propertyConfigurer" />

for creating Properties bean(same as @nkjava.blogspot.com in his answer). But this is not all work need todo.

Now you need to expose this bean to JSP. There are few way to do this, depends on type of view resolver. There is solution for InternalResourceViewResolver - you need to set "exposeContextBeansAsAttributes" to true and populate "exposedContextBeanNames" with list of required beans.

For tiles also are solution.

Than you can simply use this bean in your JSP. Via EL for example:

${propertyConfigurer['my.string.from.prop.file']}

in Spring version 4, you find the property file :

1) xml mode

                <bean class="org.springframework.context.support.PropertySourcesPlaceholderConfigurer">
                   <property name="ignoreUnresolvablePlaceholders" value="true"/>
                      <property name="locations">
                          <list>
                            <!-- default resources folder (default package maven project) -->
                             <value>classpath:mongodb.remote.properties</value>  
                                <!-- Or in /WEB-INF/ folder -->
                              <value>/WEB-INF/mongodb.remote.properties</value>  
                          </list>
                      </property>
                  </bean>
----------------------------------------------------------------------------------------

2) programmatic mode:

    If you have for example this package : com.profile.config, com.profile.controller, ecc.. 
    it's not problem if you put only com.profile, it's ok !!! Now


    @Configuration
    @ComponentScan(basePackages = "com.profile")
    /** resources folder & default package maven project*/
    @PropertySource(value = { "classpath:mongodb.remote.properties" }) 
    public class MyPropertySourcesPlaceholderConfigurer {


        @Bean
        public static PropertySourcesPlaceholderConfigurer propertySourcesPlaceholderConfigurer() {
            return new PropertySourcesPlaceholderConfigurer();
        }
    }


    ---------------------------------------------------------------------------------
    Your property file

    label.test.val=this is the property file value!!!!!
    ---------------------------------------------------------------------------------

    @Controller
    public class LabelsAndValuesController {


         @Value("${label.test.val}")
         String test;

    }

output:

    ---------------------------------------------------------------------------------
    this is the property file value!!!!!
    ---------------------------------------------------------------------------------
