Question

我必须使用ajax将数据从视图发送到控制器。这是我的类，我应该发送适合该类结构的JSON。杰克逊将JSON转换为我的班级

public class RealEstateAgencyDTO extends BaseEntityDTO {

/** The name. */
private String name;

/** The description. */
private String description;

/** The site. */
private String site;

/** The phone number. */
private String phone;

/** The address of the office. */
private AddressDTO address;


public final String getName() {
    return name;
}

public final void setName(final String newName) {
    this.name = newName;
}

public final String getDescription() {
    return description;
}

public final void setDescription(final String newDescription) {
    this.description = newDescription;
}

public final String getSite() {
    return site;
}

public final void setSite(final String newSite) {
    this.site = newSite;
}

public final String getPhone() {
    return phone;
}

public final void setPhone(final String newPhone) {
    this.phone = newPhone;
}

public final AddressDTO getAddress() {
    return address;
}

public final void setAddress(final AddressDTO newAddress) {
    this.address = newAddress;
}

}

我应该如何使用JSON.stringify（）来获得与我的结构相对应的对象

我试过像这样使用smth但它不起作用

var address = JSON.stringify({
                country: $('#country').val(),
                region: $('#description').val(),
                postalCode: $('#postalCode').val(),
                locality: $('#locality').val(),
                additionalInfo: $('#additionalInfo').val()
            });

            var data = {
                agencyName: $('#agencyName').val(),
                description: $('#description').val(),
                phoneNumber: $('#phoneNumber').val(),
                webSite: $('#webSite').val(),
                address: address
            };

             $.ajax({
                   type: "post",
                   url: "registerAgency",
                   data:  JSON.stringify(data),
                   contentType: "application/json",
                   success: function(responseData, textStatus, jqXHR) {
                       alert("data saved")
                   },
                   error: function(jqXHR, textStatus, errorThrown) {
                       console.log(errorThrown);
                   }
               })

Answer 1

你过度复杂了。直到最后才进行字符串化，否则你最终会在json中使用json，这在任何情况下都不太可能有用。

Answer 2

对象数据上的地址成员已经被字符串化。后续调用会将此视为字符串值（它是！）JSON.stringify（）将处理嵌套对象。

JSON stringify嵌套对象
