Answer 1

这样做

ProductM是您的模特

     Type type = new TypeToken<List<ProductM>>() {}.getType();
     Gson gson               = new Gson();
     List<ProductM> tempArr  = (List<ProductM>) gson.fromJson(productArray.toString(), type);// productArray -> your product array string


public class ProductM {

@SerializedName("Product_ID")
@Expose
private String productId;

@SerializedName("JAN")
@Expose
private String JAN;

@SerializedName("Feb")
@Expose
private String Feb;

@SerializedName("MAR")
@Expose
private String MAR;

public String getProductId() {
    return productId;
}

public String getJAN() {
    return JAN;
}

public String getFeb() {
    return Feb;
}

public String getMAR() {
    return MAR;
}
}
