Question

HTML代码：

我想在预先输入下拉和输入中使用两个条件：

<div ng-controller="newFIncomeCtrl">
    <div class="form-group col-md-4 in-inline err-group" show-errors>
        <label class="control-label">Bank Name<span class="text-danger">*</span></label>
        <input type="text" class="form-control input-sm" ng-model="item.bank" name="bName" tooltip="Bank Name" placeholder="Type Bank Name" typeahead="ban as ban.name for ban in banks | filter:$viewValue| limitTo:10" ng-change="change(item.bank)" ng-required=" true ">
    </div>
</div>

我的头等舱FixedIncome：

public class FixedIncome extends AbstractAuditingEntity implements Serializable {
    public static final String CUSTOMERINCOME = "customerincome";

    @Id
    private Long id;

    @DBRef
    private BankName bank;

    @NotNull
    @DBRef
    private Status status;

    private int amount;

    private DateTime investDate = null;


}

我的第二课BankName：

public class BankName implements Serializable {

    public static final String BANK = "bank";
    public static final String BANKNAME_COLLECTION = "ag.bank";

    @Id
    private Long id;

    @Size(min = 1, max = 100)
    private String name;

    @NotNull
    private String statusRefId = "ACTIVE";


    private Date createdDate = new Date();

    private Date lastModifiedDate = new Date();

    @NotNull
    private String alias;
}

我收到此error：

无法读取文档：无法从字符串值（'sdrttt'）实例化类型[simple type，＆gt; class com.advice.domain.BankName]的值; no＆gt;单字符串构造函数/工厂方法在[来源：java.io.PushbackInputStream@35e53318; line：1，column：23]（通过引用链：com.advice.domain.portfolio.FixedIncome [“bank”]）;嵌套异常是com.fasterxml.jackson.databind.JsonMappingException：无法从String值（'sdrttt'）实例化类型[simple type，class com.advice.domain.BankName]的值;没有单字符串构造函数/工厂方法在[来源：java.io.PushbackInputStream@35e53318; line：1，column：23]（通过参考链：com.advice.domain.portfolio.FixedIncome [“bank”]）

Angularjs typeahead不起作用。我想两个条件都下拉并输入
