spring mvc properties - java.io.FileNotFoundException: config.properties (The system cannot find the file specified)

I have created a properties file and trying to access this in my spring DAO class file, but am getting "java.io.FileNotFoundException: config.properties (The system cannot find the file specified)". I have tried different scenarios to put the file in different folder/locations but getting same issue. Can anybody please help me on this. Below is the code and structure details,

In DAO class,

FileReader reader = new FileReader("config.properties");
Properties properties = new Properties();
properties.load(reader);

I tried to put the "config.properties" file under src/main/resources and also under WEB-INF/. My DAO class is in src/main/java/com/test/dao Thanks in Advance.

If you are trying to read from a property file, the best practice would be to keep it in the src/main/resources folder , which is the default location for property files as per spring . The you can either use annotations to read the values in the property file, which spring will automatically read and inject.

By using @value annotation:

@Value( "${jdbc.url:aDefaultUrl}" )
private String jdbcUrl;

Note: Here you can also specify the default value.

By using xml configuration:

<bean id="dataSource">
<property name="url" value="${jdbc.url}" />
<bean>

By using the @PropertySource annotation :

@Configuration
@PropertySource("classpath:foo.properties")
public class PropertiesWithJavaConfig {
//...
}

Here you can provide the keys to be mapped in the class and it will get mapped automatically to the fields.

you can also specify multiple property files like :

@PropertySources({
@PropertySource("classpath:foo.properties"),
@PropertySource("classpath:bar.properties")
})

Note : Keep in mind for this to work the property file should have an extension like .properties and values in property file should follow the property file convention.

You can keep the file in src/main/resources where its most appropriate and change the way you retrieve it into:

ClassLoader classLoader = getClass().getClassLoader();
File file = new File(classLoader.getResource("config.properties").getFile());
FileReader reader = new FileReader(file);
