Spring Boot not recognizing application.properties file

Question

I'm trying to configure a DynamoDb client with Spring Boot, and placed my endpoints and configuration information in my resources/application.properties file. However, Spring Boot does not seem to pick up these properties. It does pick up the "server.default" key that I have stored in the same file, so it is definitely recognizing the the file itself. Here is my application.properties

Accepted Answer

You can make a try to define resources tag in the build section in your pom.xml file. Set path for resource directory where is application.properties resources ${project.build.outputDirectory} application.properties Resource Link: https://stackoverflow.com/a/30595114/2293534Another approach:If you use spring 3.X version, You can add @PropertySource("application.properties")@Configuration@PropertySource(value = "classpath:application.properties")public class ApplicationConfig { // more configuration ...}If you use spring 4 version, you add 2 properties file using new annotation called @PropertySources that allows you to declare repeated @PropertySource annotations:@PropertySources({ @PropertySource("default.properties"), @PropertySource("overriding.properties")})Details is given here in my another answer: https://stackoverflow.com/a/43659158/2293534UPDATE #1:Replace your App.java class with following classimport org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.EnableAutoConfiguration;import org.springframework.boot.autoconfigure.SpringBootApplication;import org.springframework.boot.builder.SpringApplicationBuilder;import org.springframework.boot.context.web.SpringBootServletInitializer;import org.springframework.context.annotation.ComponentScan;import org.springframework.context.annotation.Configuration;//@SpringBootApplication@Configuration@ComponentScan@EnableAutoConfigurationpublic class Application extends SpringBootServletInitializer { public static void main(String[] args) { SpringApplication.run(Application.class, args); } @Override protected SpringApplicationBuilder configure(SpringApplicationBuilder application) { return application.sources(applicationClass); } private static Class applicationClass = Application.class;}For java.io.FileNotFoundException:Use the following@PropertySource(value = "database.properties", ignoreResourceNotFound = true)UPDATE #2:I have followed the following steps to run your application. It runs successfully.Go to your project folder where pom.xml is exists.You have some errors and warning on pom.xml. I have clarified all.Open command prompt and Run mvn cleanRun mvn clean installAt last mvn spring-boot:runThen in browser, I run http://localhost:8080/It opens the project successfully. I have also searched other pages also opened successfully.First page looks like below http://localhost:8080/All Review pages look like below: http://localhost:8080/api/reviews[ {"id":1,"userName":"ychennay","reviewText":"This restaurant was terrific!"},{"id":2,"userName":"david","reviewText":"This restaurant was okay!"}, {"id":3,"userName":"ben","reviewText":"This restaurant was mediocre!"}, {"id":4,"userName":"leon","reviewText":"This restaurant was awful!"}, {"id":5,"userName":"lawrence","reviewText":"This restaurant was confusing!"}]So Replace your pom.xml 4.0.0 com.diningapp Dining 0.0.1-SNAPSHOT war 2.7.5
