how to Autowire the applicationContext early?

Question:

Tag: spring,spring-boot

Using spring boot, how to Autowire the applicationContext ?

It must be autowired before the call of endpoint()

@Configuration
@EnableTransactionManagement
@EnableAutoConfiguration
@ComponentScan({"com.dev.core.services", "com.dev.core.wservices"})
@ImportResource({ "classpath:META-INF/cxf/cxf.xml" })
public class ContextConfig extends SpringBootServletInitializer {
    @Autowired
    private static ApplicationContext applicationContext;
    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(ContextConfig.class);
    }   
    @Bean 
    public EndpointImpl endpoint() { 
    //  applicationContext is null how to fix that ?
        EndpointImpl endpoint = 
           new EndpointImpl(cxfBus, applicationContext.getBean(IWCustomerService.class) ); 
        endpoint.publish("/CustomerService"); 
        return endpoint; 
    } 
}

Answer:

static fields are ignored by Spring.

Unless you're in some kind of main method, setting up your application, you should never have to use the ApplicationContext directly.

Here, you want to use it to extract a bean of type IWCustomerService. Instead, let Spring inject it for you.

@Bean 
public EndpointImpl endpoint(IWCustomerService customerService) { 
    EndpointImpl endpoint = 
       new EndpointImpl(cxfBus, customerService); 
    endpoint.publish("/CustomerService"); 
    return endpoint; 
}
