Question

我有一个基本表单，想提交它。但是，我无法实现发布bean的属性，即类的类型。

html：

<!DOCTYPE html>
<html lang="en">

<head th:replace="common/header :: common-header" />
<div th:replace="common/header :: navbar"></div> 
 
<body >
	
   <div class="container" style="margin-top:5%">
 
    <!-- Page Features -->
    
      <form class="form-vertical" th:action="@{/sendDeposit}" method="post" th:object="${deposit}">
        
        <div class="form-group">
						<label class="col-md-2 control-label" for="userCredit">Your Credit</label>
						<div class="col-md-8">
							<input type="text" name="userCredit" class="form-control" id="userCredit"
								th:value="${userCredit.amount}" readonly placeholder="Amount" />							
						</div>
          </div>
        
        <div class="form-group">
						<label class="col-md-2 control-label" for="username">Amount</label>
						<div class="col-md-8">
							<input type="text" name="amount" class="form-control" id="amount"
								th:value="${deposit.amount}" required="required" placeholder="Amount" />							
						</div>
          </div>
          
          <div class="form-group">
						<label class="col-md-2 control-label" for="username">Sent To</label>
						<div class="col-md-8">
							<input type="text" name="sentTo" class="form-control" id="depositUsername" th:field="*{sentTo.username}"
								th:if="${deposit.sentTo}!=null" th:value="${deposit.sentTo.username}"  
								required="required" placeholder="username" />		
								<input type="text" name="sentTo" class="form-control" id="depositUsername" th:field="*{sentTo.username}"
								th:if="${deposit.sentTo}==null"  
								required="required" placeholder="username" />						
						</div>
          </div>
          
          <div class="form-group">
						<label class="col-md-2 control-label" for="username">Currency</label>
						<div class="col-md-8">
							 <select class="form-control" th:field="*{id}"  id="currency">
                <option value="-1">Select Currency</option>
                <option th:each="currency : ${currency}" th:value="${currency.id}" th:text="${currency.name}"></option>
              </select>						
						</div>
					</div>
					<div class="form-group">
						<div class="col-md-2"></div>
						<div class="col-md-8">
							<button type="submit" id="send" class="btn btn-primary">Send</button>
							<a class="btn btn-warning" th:href="@{/}">Cancel</a>
						</div>
					</div>
				</form>
     
         
				 
				</div>    
    <!-- /.container -->
 
   
<div th:replace="common/header :: body-bottom-scripts"></div>
<script>
	$("#send").on("click",function(){
    $("#depositUsername").val($("#depositUsername").text);
	})
	
	</script>
</body>

</html>

域类（bean）：

package com.downpayment.domain;
import java.util.Date;
import javax.persistence.CascadeType;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.OneToOne;

@Entity
public class Deposit {
@Id
@GeneratedValue(strategy=GenerationType.AUTO)
@Column(name="id", nullable = false, updatable = false)
private int id;
private String additionalNote;
private int amount;
private String currency;    
private User sentBy;    
private User sentTo;

@OneToOne(mappedBy="deposit",cascade=CascadeType.ALL)    
private Credit userCurrentCredit;



public String getAdditionalNote() {
    return additionalNote;
}
public void setAdditionalNote(String additionalNote) {
    this.additionalNote = additionalNote;
}
public int getAmount() {
    return amount;
}
public void setAmount(int amount) {
    this.amount = amount;
}
public String getCurrency() {
    return currency;
}
public void setCurrency(String currency) {
    this.currency = currency;
}
public User getSentBy() {
    return sentBy;
}
public void setSentBy(User sentBy) {
    this.sentBy = sentBy;
}
public User getSentTo() {
    return sentTo;
}
public void setSentTo(User sentTo) {
    this.sentTo = sentTo;
}   
public int getId() {
    return id;
}

}

控制器方法：

@RequestMapping(value="/sendDeposit", method=RequestMethod.POST)
public String saveUser(@ModelAttribute  Deposit deposit, HttpServletRequest request) {
    User sentByUser=userService.findByUsername(deposit.getSentBy().getUsername());
    User sentToUser=userService.findByUsername(deposit.getSentTo().getUsername());
    Optional<Credit> crSentBy=creditService.findByUser(sentByUser);
    Optional<Credit> crSentTo=creditService.findByUser(sentToUser);
    float delta=deposit.getAmount();

    crSentBy.get().setAmount(crSentBy.get().getAmount()-delta);
    crSentTo.get().setAmount(crSentTo.get().getAmount()+delta);      

    return "send";
}

我该如何绑定到用户类类型的Deposit的sendTo属性？似乎在准备在我的html上制作百里香叶模板时却做错了，但无法意识到我做错了什么。

如何使用Tyhmeleaf
