Tomcat Not reading Spring-Boot Application Properties

Question

I\'m fairly new to spring/java and have been checking out spring-boot for a project I have at work. I\'ve been following guides and finally have a (semi) working web app MVC

Answer 1

I think for those who change default naming "application.[properties,yaml,etc]" to, for example, "service.[properties,yaml,etc]", can add this into the build.gradle task as:

bootRun {
    systemProperties = [
       'spring.config.name':'service'
    ]
}

Answer 2

I came here searching for the same issue. application.properties not loading when spring boot application run as a war inside tomcat but it was working fine when running with embedded tomcat. the issue turned out to be in the file name . I had used Application.properties instead of application.properties . when running from tomcat it looks like it is case sensitive . Putting it here so that if someone commits the same stupid mistake as i did

Answer 3

follow this guys advice: http://blog.codeleak.pl/2013/11/how-to-propertysource-annotations-in.html

try:

@PropertySources(value = {@PropertySource("classpath:application.properties")})

then boom sauce for the win.

Answer 4

The problem is that you attempt to use a @Value annotation inside your @Configuration class. From the JavaDoc of the @PropertySource:

In order to resolve ${...} placeholders in <bean> definitions or @Value annotations using properties from a PropertySource, one must register a PropertySourcesPlaceholderConfigurer. This happens automatically when using <context:property-placeholder> in XML, but must be explicitly registered using a static @Bean method when using @Configuration classes.

e.g. add the following lines to the @Configuration class:

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

---

However, in your example, a more suitable approach is to move the @Configuration annotation from the GreetingController class (it does not contain any configuration) to the Application class. Since the Application class does not contain any @Value annotation it should work without the suggested addition of the static PropertySourcesPlaceholderConfigurer bean.
