Issue
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 file and the class I'm trying to load properties into (DynamoDBClientMapper):
amazon.dynamodb.endpoint=http://localhost:8000/
amazon.dynamodb.region=us-west-1
amazon.aws.accesskey=key
amazon.aws.secretkey=key2
server.port=8080
Here is my project structure:
Here is the relevant class I'm trying to load properties into. I tried the @PropertySource annotation with a new properties file, as well as EnableAutoConfiguration, but neither are registering the properties file(s).
@PropertySource("database.properties")
public class DynamoClientMapper {
@Value("${amazon.dynamodb.endpoint}")
private String amazonDynamoDBEndpoint;
@Value("${amazon.aws.accesskey}")
private String amazonAWSAccessKey;
@Value("${amazon.aws.secretkey}")
private String amazonAWSSecretKey;
@Value("${amazon.aws.region}")
private String amazonAWSRegion;
Here is my App.java:
@SpringBootApplication
@EnableAutoConfiguration(exclude = {DataSourceAutoConfiguration.class})
public class App {
// private static final Logger logger = Logger.getLogger(App.class.toString());
public static void main(String[] args){
SpringApplication.run(App.class, args);
}
}
Here is the stack trace:
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dynamoClientMapper' defined in file [C:\Users\ychen4\Desktop\DiningApplication\target\classes\main\java\com\dining\dao\DynamoClientMapper.class]: Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [main.java.com.dining.dao.DynamoClientMapper$$EnhancerBySpringCGLIB$$f4ba10ad]: Constructor threw exception; nested exception is java.lang.IllegalArgumentException: endpoint cannot be null

I've tried making another separate database.properties file , but Spring Boot isn't recognizing that either. What am I doing wrong?
Solution
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
<build>
<resources>
<resource>
<directory>resources</directory>
<targetPath>${project.build.outputDirectory}</targetPath>
<includes>
<include>application.properties</include>
</includes>
</resource>
</resources>
</build>
Resource Link: https://stackoverflow.com/a/30595114/2293534
Another 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/43659158/2293534
UPDATE#1:
Replace your App.java class with following class
import 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
@EnableAutoConfiguration
public 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<Application> 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:run
Then in browser, I run "http://localhost:8080/"
It open's the project successfully. I have also searched other pages also opened successfully.
First page looks like below http://localhost:8080/
Review all pages looks 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
