armeria-0.60.0

New features

• #1049 Spring Boot 2 support

  • Use the artifact armeria-spring-boot2-autoconfigure or armeria-spring-boot2-autoconfigure-shaded.

• #1066 #1096 Parameter and header injection into bean property and constructor for annotated services. See the official documentation for more information.

  public class FinderService {
      @Get("/find/:id")
      public String find(@RequestObject FindRequest req) { ... }
  }
  
  // Using constructor
  public class FindRequest {
      public FindRequest(@Param("id") String id, @Header("x-type") String type) {
          this.id = id;
          this.type = type;
      }
      ...
  }
  
  // Using fields
  public class FindRequest {
      @Param("id") private String id;
      @Header("x-type") private String type;
  }
  
  // Using setters
  public class FindRequest {
      public void setId(@Param("id") String id) { ... }
      public void setType(@Header("x-type") String type) { ... }
  }
  
  // Using multi-field setters
  public class FindRequest {
      public void setAll(@Param("id") String id, @Header("x-type") String type) { ... }
  }

• #1085 Easier self-signed TLS certificate generation with ServerBuilder.tlsSelfSigned(), which may be very useful for testing

  ServerBuilder sb = new Serverbuilder();
  sb.https(8443);
  sb.tlsSelfSigned();

• #1087 #1089 Endpoint.ipAddr(), which allows specifying an IP address explicitly for an Endpoint. This is a preparatory work for providing better DNS-based service discovery.

• #1090 MoreNamingConventions.configure(), which configures a Micrometer MeterRegistry to use our better naming convention

• #1099 #1100 #1101 PROXY protocol support, which is useful when you are behind a load balancer such as HAProxy and AWS ELB

  ServerBuilder sb = new ServerBuilder();
  sb.port(8080, SessionProtoxol.PROXY, SessionProtocol.HTTP);

• #1099 #1100 #1101 Ability to serve HTTP and HTTPS on the same port

  ServerBuilder sb = new ServerBuilder();
  sb.port(8888, SessionProtoxol.HTTP, SessionProtocol.HTTPS);
  // You can even enable PROXY protocol support, too.
  sb.port(9999, SessionProtoxol.PROXY, SessionProtocol.HTTP, SessionProtocol.HTTPS);

Bug fixes

• #1091 Potential buffer leaks due to empty ByteBufHttpData
• #1092 #1097 Buffer leak in StreamMessageDuplicator.close(), which affects RetryingClient
• #1111 Rename the gauge armeria.server.numConnections to armeria.server.connections

Breaking changes

• #1110 From this release, Armeria HTTP client will send HTTP/2 connection preface string PRI * HTTP/2.0 first when the URI scheme is http, in lieu of sending the HTTP/1 upgrade request HEAD / HTTP/1.1.
  • Specify -Dcom.linecorp.armeria.defaultUseHttp2Preface=false JVM option or use ClientFactoryBuilder.useHttp2Preface(false) to go back to the old behavior.
