Springboot - @Autowired null with injection
0
I have a Spring-boot project and I need to get values from application.properties file because of profiles.
But when injecting a config file in the class, the object return null.
Application.properties:
server.ip=000.000.000.000
server.port=0000
Config Class:
@Component
@ConfigurationProperties(prefix = "server")
public class AppProperties {
private String ip;
private Integer port;
... getters and setters
the class where I need the values:
@Component
public class Teste {
@Autowired
private AppProperties properties;
...
socket = new Socket(properties.getIp(), properties.getPort());
On debugging, at the start of the application, the values in AppProperties get a correct value.

For me your code works. Do you have thespring-boot-configuration-processordependency included in your build file? STS warns about this on@ConfigurationPropertieswhen it is missing.

Nullpointer in variable "properties" on start socket. I have spring-boot-configuration-processor dependency. I need use profiles because different environments. I have 3 configuration files: application.properties, application-pro.properties and application-dev.properties. The configurations about database work correctly in all environments. The properties "ip" and "port" exists in all application.properties files.

You can use @Value annotation to access the property values from application.properties file like this
@Value("${<propertname>}")
private String userBucketPath;

Your code looks like correct but I would like to suggest you try with below steps also:
Use @PropertySource annotation to define properties location. (I knew default location is classpath).
If you really need to add a profile to your project. Create a new application property file like application-{profile-name}.properties and while starting an application pass JVM argument -Dspring.profiles.active={profile-name}.
I don't know it's exact need or answer for you. I'm just trying to share an additional step.

For me your code works. Do you have the
spring-boot-configuration-processordependency included in your build file? STS warns about this on@ConfigurationPropertieswhen it is missing.– Thomas Fritsch

i nedd get values from application.properties file because of profiles. Umm i don't get why would you do this "because of profiles". Both things exists and can be used separately.

remove that
@ComponentfromAppPropertiesthis should be sufficient@ConfigurationProperties(prefix = "server")– Deadpool

Nullpointer in variable "properties" on start socket. I have spring-boot-configuration-processor dependency. I need use profiles because different environments. I have 3 configuration files: application.properties, application-pro.properties and application-dev.properties. The configurations about database work correctly in all environments. The properties "ip" and "port" exists in all application.properties files.
