Spring @ConfigurationProperties not working
Asked on June 09, 2019
I want to use Spring Boot @ConfigurationProperties in my application. But its is not working. Find my code.
1.
@Configuration
@PropertySource("classpath:user.properties")
public class AppConfig {
@Bean
public User getUser() {
User user = new User();
return user;
}
}
2.
@ConfigurationProperties
public class User {
String name;
String age;
}
3.
//user.properties
name=John
age=30
4.
@SpringBootApplication
@EnableConfigurationProperties
public class MySpringBootApp {
public static void main(String[] args) {
final ApplicationContext ctx = SpringApplication.run(MySpringBootApp.class, args);
final User user = ctx.getBean(User.class);
System.out.println(user.name);
System.out.println(user.age);
}
}
5.
//Output
null
null
How to fix it?

You are missing setters and getters in User class. Create setters and getters.
@ConfigurationProperties
public class User {
String name;
String age;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getAge() {
return age;
}
public void setAge(String age) {
this.age = age;
}
}
public class User {
String name;
String age;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getAge() {
return age;
}
public void setAge(String age) {
this.age = age;
}
}
Then try.
