Question

I use Spring MVC with java config.

And I have two context configuration classes: RootContext and ServletContext.

RootContext class is loaded via <context-param> in web.xml

Here is the code of RootContext:

@Configuration
@EnableTransactionManagement
@Import(DaoConfig.class)
@PropertySource("/WEB-INF/config/application.properties")
public class RootContext {

    @Autowired
    private Environment env;

    @Bean(destroyMethod = "close")
    public DataSource dataSource() {
        BasicDataSource dataSource = new BasicDataSource();
        dataSource.setDriverClassName(env.getProperty("jdbc.driverClassName"));
        dataSource.setUrl(env.getProperty("jdbc.url"));
        dataSource.setUsername(env.getProperty("jdbc.username"));
        dataSource.setPassword(env.getProperty("jdbc.password"));
        return dataSource;
    }

    @Bean
    public PlatformTransactionManager transactionManager() {
        return new DataSourceTransactionManager(dataSource());
    }
}

If I run the application, I got this error:

java.io.FileNotFoundException: class path resource [WEB-INF/config/application.properties] cannot be opened because it does not exist

Everything works fine if I move application.properties file to classpath. But I want it to be in /WEB-INF/config directory.

Any suggestion how to solve this error?

Should I put @PropertySource("/WEB-INF/config/application.properties") line to ServletContext instead of RootContext??

Thank you.

I know this is a late reply but I hope this may be useful for anyone having the same issue.

You can do this by setting context-param in your web.xml and access it in configuration class with @PropertyResource.

web.xml

<context-param>
    <param-name>myProperties</param-name>
    <param-value>${catalina.home}/conf/application.properties</param-value>
</context-param>

AppConfig.class

@Configuration
@PropertySource("file:${myProperties}")
public class AppConfig{

    @Autowired
    Environment env;
