How to bind a object with Guice in Dropwizard?

Question

I want to use a bind object in my service class with guice in dropwizard.

Consider the object

public class MinioData {
  private String endpoint;
public String getEndpoint() {
    return endpoint;
  }
}

And a service

@Path("/upload")
@Produces(MediaType.APPLICATION_JSON)
public class UploadResource {
private final MinioData minioData;
@Inject
public UploadResource(
    @Named("miniodata") MinioData minioData) {
  this.minioData = minioData;
}

How can I bind this object so that can be used in my service. For a String I could use

bindConstant()
.annotatedWith(Names.named("miniodata"))
.to(configuration.getMiniodata());

but since in this case it is a general object how would I bind it?

如果在DW应用程序中配置了现有的Guice模块，则只需将MinioData实例从配置对象绑定到关联的类：

binder.bind(MinioData.class).toInstance(configuration.getMiniodata());
