You can use the <code>@Value</code> to load variables from the <code>application.properties</code> if you will use this value in one place, but if you need a more centralized way to load this variables <code>@ConfigurationProperties</code> is a better approach.

Additionally you can load variables and cast it automatically if you need different data types to perform your validations and business logic.

<pre><code>application.properties
custom-app.enable-mocks = false

@Value("${custom-app.enable-mocks}")
private boolean enableMocks;

Then wherever you want to read from application.properties, just pass the key to getConfigValue method.

For me, none of the above did directly work for me.
What I did is the following:

Additionally to @Rodrigo Villalba Zayas answer up there I added 
<code>implements InitializingBean</code> to the class 
and implemented the method 

<pre><code>@Override
public void afterPropertiesSet() {
 String path = env.getProperty("userBucket.path");
}
</code></pre>

So that will look like

<pre><code>import org.springframework.core.env.Environment;
public class xyz implements InitializingBean {

 @Autowired
 private Environment env;
 private String path;

 ....

 @Override
 public void afterPropertiesSet() {

 System.out.println("Path: " + path);

follow these steps.
1:- create your configuration class like below you can see

@Configuration
public class YourConfiguration{

 // passing the key which you set in application.properties
 @Value("${userBucket.path}")
 private String userBucket;

 // getting the value from that key which you set in application.properties
 @Bean
 public String getUserBucketPath() {
 return userBucket;
 }
}
</code></pre>

2:- when you have a configuration class then inject in the variable from a configuration where you need.

<pre><code>@Component
public class YourService {

 @Autowired
 private String getUserBucketPath;

 // now you have a value in getUserBucketPath varibale automatically.
}

You can use <code>@Value(&quot;${property-name}&quot;)</code> from the
application.properties if your class is annotated with
<code>@Configuration</code> or <code>@Component</code>.
There's one more way I tried out was making a Utility class to read properties in the following way -
<pre><code> protected PropertiesUtility () throws IOException {
 properties = new Properties();
 InputStream inputStream = 
 getClass().getClassLoader().getResourceAsStream(&quot;application.properties&quot;);
 properties.load(inputStream);

You can make use of static method to get the value of the key passed as the parameter.

blocks|key|4499579|text|要从属性文件中挑选值，我们可以有一个类似于ApplicationConfigReader.class的配置读取器类，然后根据属性定义所有变量。请参考下面的示例：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4499580|application.properties

class+AppConfigReader{
++++private+String+nationality;
++++private+String+gender

++++//getter+&+setter
}|4499583|现在，我们可以在任何需要访问属性值的地方自动连接reader类。例如：|4499584|@Service
class+ServiceImpl{
++++@Autowired
++++private+AppConfigReader+appConfigReader;

++++//...
++++//fetching+values+from+config+reader
++++String+nationality+=+appConfigReader.getNationality()+;+

to pick the values from property file, we can have a Config reader class something like ApplicationConfigReader.class
Then define all the variables against properties. Refer below example,
<pre><code>application.properties

myapp.nationality: INDIAN
myapp.gender: Male
</code></pre>
Below is corresponding reader class.
<pre><code>@Component
@EnableConfigurationProperties
@ConfigurationProperties(prefix = &quot;myapp&quot;) 
class AppConfigReader{
 private String nationality;
 private String gender

 //getter &amp; setter
}
</code></pre>
Now we can auto-wire the reader class wherever we want to access property values.
e.g.
<pre><code>@Service
class ServiceImpl{
 @Autowired
 private AppConfigReader appConfigReader;

 //...
 //fetching values from config reader
 String nationality = appConfigReader.getNationality() ; 
 String gender = appConfigReader.getGender(); 
}

There are 3 ways to read the application.properties,
using @Value, EnvironmentInterface and @ConfigurationProperties..
<pre><code>@Value(${userBucket.path})
private String value;
</code></pre>
2nd way:
<pre><code>@Autowired
private Environment environment;

String s = environment.getProperty(&quot;userBucket.path&quot;);
</code></pre>
3rd way:
<pre><code>@ConfigurationProperties(&quot;userbucket&quot;)
public class config {

private String path;
//getters setters

}
</code></pre>
Can be read with getters and setters..

logging.file=${HOME}/application.log

I want to access <code>userBucket.path</code> in my main program in a Spring Boot application.
