I'm integrating a external project contract service client in my project(Menu provider service) in context.xml. I'm using spring boot to run my project in STS, I'm going through below error while starting the spring boot application.

Spring Boot Application class:
@SpringBootApplication
@EnableConfigurationProperties({ MenuProviderServiceConfig.class, CreateRatesConfig.class,CommonConfiguration.class, ContractClientConfig.class })
@Import({
    CommonConfiguration.class
@ImportResource({ "classpath:/menu-provider-service/context.xml" })
public class MenuProviderServiceApplication
@EnableConfigurationProperties annotation expects all the classes provided, in argument, should be annotated with @ConfigurationProperties.
Annotate the class ContractClientConfig with @ConfigurationProperties and it should work.
remove @EnableConfigurationProperties annotation
init config properties POJOs directly as beans
  @Bean
  @ConfigurationProperties(prefix = "app.my-menu")   // spring will get app.my-menu.* properties 
  MenuProperties menuConfig() {                      // and will set them into
    return new MenuProperties();                     // the returned object

Details:
A better way to re-use ConfgigurationPropertes from external (as well as from local) project is to init the property objects explicitly in your @Configuration class. So you don't need any @EnableProperties, or @ConfigurationProperties annotations. Especially, in external projects, where you don't have control over.
The above snippet assumed two things: your application.yml has app.my-menu.* properties:
  my-menu:
    text: "Help"
    path: "/help/index.html"
The POJO properties class has setters with the same as properties names:
public class MenuProperties {
  public String text;                           // getters are optional
  public String path;
  public void setText(String v) { text = v; }   // setters is a must
  public void setPath(String v) { path = v; }
