AmqpItemReader和死信队列(AmqpItemReader and Dead Letter Queue)

 我试图实现从队列中读取消息并在发生错误时将它们移动到死信的作业。 我试图使用事务处理的频道，但它总是重新发送消息。  
 有没有自动的方式来做到这一点与Spring批处理时，抛出异常？ 

I'm trying to implement a job that reads messages from a queue and move them to dead letter when an error occurs. I've tried to use a transacted channel but it always requeue the message. 
Is there any automatic way to do that with Spring Batch when an exception is thrown?

 您将无法得到答案，因为您的代码工作正常（我只是删除了自定义元素）：  
 https://jsfiddle.net/ferahl/4x34ae37/  
var SignupComponent = React.createClass({
getInitialState: function(){
  console.log('getInitialState');
  return {}
    },    
_onSubmit: function (e){
  console.log('hello _onSubmit');
  },
_onChange: function(){
  console.log('hello _onChange');
  },
  render: function(){  
      return(
        <form ref='sugnup_form' onSubmit={this._onSubmit}>
            <div className="col-md-5">
              <p className="h3">Signup Form</p>
              <input placeholder="Enter Your Name" name="user_name" onChange={this._onChange}/>
              <input placeholder="Enter Your Email" onChange={this._onChange} name="email"/>
              <input placeholder="Enter Your Password" name="password"/>
              <input className="btn btn-success" type="submit" value="Submit" />
            </div>
        </form>
    )
  }
});


ReactDOM.render(
  <SignupComponent />,
    document.getElementById('container')
);

You won't get answers to this because your code works fine (I just removed the custom elements): 
https://jsfiddle.net/ferahl/4x34ae37/ 
var SignupComponent = React.createClass({
getInitialState: function(){
  console.log('getInitialState');
  return {}
    },    
_onSubmit: function (e){
  console.log('hello _onSubmit');
  },
_onChange: function(){
  console.log('hello _onChange');
  },
  render: function(){  
      return(
        <form ref='sugnup_form' onSubmit={this._onSubmit}>
            <div className="col-md-5">
              <p className="h3">Signup Form</p>
              <input placeholder="Enter Your Name" name="user_name" onChange={this._onChange}/>
              <input placeholder="Enter Your Email" onChange={this._onChange} name="email"/>
              <input placeholder="Enter Your Password" name="password"/>
              <input className="btn btn-success" type="submit" value="Submit" />
            </div>
        </form>
    )
  }
});


ReactDOM.render(
  <SignupComponent />,
    document.getElementById('container')
);
