no qualifying bean of type 'java.lang.string' available error in spring-CodePudding

I am getting no qualifying bean of type 'java.lang.string' available error in spring, NoSuchBeanDefinitionException in the following code. I have Test.java like the following, where I am trying to read the value from application.yaml.

@Configuration
public class Test {

    @Value("${value}")
    private String val;
    
    @Bean
    public Vehicle getVehicle() {
    return new Vehicle(val);
    }
}

In Vehicle.java

@AllArgConstructor
@Getter
@Setter
public class Vehicle {

private String model;

}

I have another class, Driver.java, from where I have to inject Vehicle object through constructor.

@Service
public class Driver {

private Vehicle v;

@Autowired
public Driver(Vehicle v) {
  this.v = v;
}

application.yaml looks like this.

value: FORTUNE
price: 10000

CodePudding user response：

You can try a different way to inject this:

You don't need to create a configuration class where you inject the property as field and then create a bean of Vehicle. You can use constructor injection in Vehicle and make Vehicle a Component with @Component annotation;

@Getter
@Setter
@Component
public class Vehicle {
    private String model;
    
    public Vehicle(@Value("${value}") String model) {
        this.model = model
    }
}

I personally prefer this way and I hope it works for you!
