JSON stringify嵌套对象

Question

我必须使用ajax将数据从视图发送到控制器。下面是我类，我应该将适当的JSON发送到类结构中。Jackson会把JSON转换成我的类

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()来获得这样一个符合我的结构的对象

我试过这样使用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);
                   }
               })

你把事情搞得太复杂了。不要在最后才使用字符串，否则最终会在json中使用json，这在任何情况下都不太可能有用。

var address = {
    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);
    }
});

对象数据上的address成员已被字符串标识。随后的调用会将其视为字符串值(它确实是！)JSON.stringify()可以很好地处理嵌套对象。
