spi-gh-8609

Repro project for spring-integration issue spring-projects/spring-integration#8609.

NOTE:

This issue will be fixed via 6.1.0, 6.0.6 and 5.5.18.

How to use the patch interceptor

This project provide the workaround sample interceptor(SpringIntegrationIssue8609PatchInterceptor) for fix this issue. The SpringIntegrationIssue8609PatchInterceptor's factory should be applied to the TcpConnectionInterceptorFactoryChain at last.

Introduce sample bean definitions that applied patch interceptor to your application.

Define beans with Java Configuration

@Bean
public AbstractServerConnectionFactory serverConnectionFactory(
    List<TcpConnectionInterceptorFactory> tcpConnectionInterceptorFactories) {
  return Tcp.netServer(1234)
      .deserializer(TcpCodecs.crlf())
      .interceptorFactoryChain(tcpConnectionInterceptorFactoryChain(tcpConnectionInterceptorFactories))
      .get();
}

private TcpConnectionInterceptorFactoryChain tcpConnectionInterceptorFactoryChain(
    List<TcpConnectionInterceptorFactory> tcpConnectionInterceptorFactories) {
  TcpConnectionInterceptorFactoryChain chain = new TcpConnectionInterceptorFactoryChain();
  chain.setInterceptors(tcpConnectionInterceptorFactories.toArray(new TcpConnectionInterceptorFactory[0]));
  return chain;
}

@Bean
@Order(1)
public TcpConnectionInterceptorFactory myInterceptor1() {
  return new MyInterceptor1.Factory();
}

@Bean
@Order(2)
public TcpConnectionInterceptorFactory myInterceptor2() {
  return new MyInterceptor2.Factory();
}

@Bean
@Order(3) // ★★★Should set order at last★★★
public TcpConnectionInterceptorFactory patchInterceptor() {
  return new SpringIntegrationIssue8609PatchInterceptor.Factory();
}

Define beans with XML Configuration

<ip:tcp-connection-factory id="serverConnectionFactory"
  type="server"
  port="1234"
  serializer="crLfSerializer"
  deserializer="crLfSerializer"
  interceptor-factory-chain="tcpConnectionInterceptorFactoryChain" />

<bean id="tcpConnectionInterceptorFactoryChain" class="org.springframework.integration.ip.tcp.connection.TcpConnectionInterceptorFactoryChain">
  <property name="interceptors">
    <array>
      <bean class="com.example.MyInterceptor1.Factory"/>
      <bean class="com.example.MyInterceptor2.Factory"/>
      <bean class="com.example.spigh8609.SpringIntegrationIssue8609PatchInterceptor.Factory"/> <!-- ★★★Should define the bean at last★★★ -->
    </array>
  </property>
</bean>
