Question

以下是来自Web服务的public class Product { private int id,price,discount; private String name,image,description,discount_type,discount_exp; @SerializedName("products") private List<Product> products; public Product() { } }响应：

Show Image

和Java类：

db.foo.find({"_id" : ObjectId("59b0303bfe409a21fccc9523")})
.map(function(u){
        return u.Departments
                .filter(p => p.Guid == "D5950FC8-91B1-48A3-8B6A-F3A72FAC9175")
    }
)

响应为空

Answer 1

问题是产品包含在JSON响应的数据字段中。 Retrofit不知道这一点，因此无法将响应反序列化为Product数组。

Answer 2

你必须改变它会起作用

<h1>Image in src attribute</h1>
<img width="30" src="http://c.reapic1.com/camera.svg">
<h1>Image in content url</h1>
<div class="test-content">
  <img>
</div>
<h1>Image in before content url</h1>
<div class="test-before-content">
  <img>
</div>
<h1>Image in after content url</h1>
<div class="test-after-content">
  <img>
</div>
<h1>Image as background</h1>
<div class="test-background">
  <img>
</div>

Answer 3

POJO class错误

试试这个

public class Products_Main
{
  @SerializedName("current_page")
  int current_page;

  @SerializedName("data")
  private List<Product> products;

  public int getCurrent_page() {
    return current_page;
  }

  public void setCurrent_page(int current_page) {
    this.current_page = current_page;
  }

  public List<Product> getProducts() {
    return products;
  }

  public void setProducts(List<Product> products) {
    this.products = products;
  }
}

和

class Product {

    @SerializedName("id")
    private int id;

    @SerializedName("price")
    int price;

    @SerializedName("discount")
    int discount;

    @SerializedName("name")
    private String name;

    @SerializedName("image")
    private String image;

    @SerializedName("description")
    private String description;

    @SerializedName("discount_type")
    private String discount_type;

    @SerializedName("discount_exp")
    private String discount_exp;

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public int getPrice() {
        return price;
    }

    public void setPrice(int price) {
        this.price = price;
    }

    public int getDiscount() {
        return discount;
    }

    public void setDiscount(int discount) {
        this.discount = discount;
    }

    public String getName() {
        return name;
    }

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

    public String getImage() {
        return image;
    }

    public void setImage(String image) {
        this.image = image;
    }

    public String getDescription() {
        return description;
    }

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

    public String getDiscount_type() {
        return discount_type;
    }

    public void setDiscount_type(String discount_type) {
        this.discount_type = discount_type;
    }

    public String getDiscount_exp() {
        return discount_exp;
    }

    public void setDiscount_exp(String discount_exp) {
        this.discount_exp = discount_exp;
    }
}

Answer 4

解析失败时会发生任何空数据。

这是您已经显示的回复的Java

public class ProductResponse {
    ProductPage products;
} 

public class ProductPage {
    int current_page;

    @SerializedName("data")
    private List<Product> products;
} 

public class Product {
  private int id,price,discount;
  private String name,image,description,discount_type,discount_exp;

  public Product() { }

}

Answer 5

你应该像那样使用它

=＆gt;主API模型类

 public class APIResult {
        @SerializedName("products")
        private ProductModelClass products;

        public ProductModelClass getProducts() {
            return products;
        }

        public void setProducts(ProductModelClass products) {
            this.products = products;
        }
    }

=＆gt;对于数据和当前页面模型类

public class ProductModelClass {

    @SerializedName("current_page")
    private int current_page;

    @SerializedName("data")
    private ArrayList<ProductDataModel> data;

    public int getCurrent_page() {
        return current_page;
    }

    public void setCurrent_page(int current_page) {
        this.current_page = current_page;
    }

    public ArrayList<ProductDataModel> getData() {
        return data;
    }

    public void setData(ArrayList<ProductDataModel> data) {
        this.data = data;
    }
}

=＆gt;有关产品数据的详细信息

public class ProductDataModel {

    @SerializedName("id")
    private int id;

    @SerializedName("name")
    private String name;

    @SerializedName("image")
    private String image;
