Fastjson BeanToArray
Dalam fastjson, mod pemetaan yang dipanggil BeanToArray disokong. Dalam mod biasa, JavaBean dipetakan ke objek json, dan mod BeanToArray dipetakan kepada tatasusunan json.
Contoh 1
class Mode {
public int id;
public int name;
}
Model model = new Model();
model.id = 1001;
model.name = "gaotie";
// {"id":1001,"name":"gaotie"}
String text_normal = JSON.toJSONString(model);
// [1001,"gaotie"]
String text_beanToArray = JSON.toJSONString(model, SerializerFeature.BeanToArray);
// support beanToArray & normal mode
JSON.parseObject(text_beanToArray, Feature.SupportArrayToBean);Dalam contoh di atas, dalam mod BeanToArray, tiada output Key, yang menjimatkan ruang, rentetan json lebih kecil dan prestasi akan menjadi lebih baik. . kebolehbacaan yang lebih baik. Contoh 3
class Company {
public int code;
public List<Department> departments = new ArrayList<Department>();
}
@JSONType(serialzeFeatures=SerializerFeature.BeanToArray, parseFeatures=Feature.SupportArrayToBean)
class Department {
public int id;
public Stirng name;
public Department() {}
public Department(int id, String name) {this.id = id; this.name = name;}
}
Company company = new Company();
company.code = 100;
company.departments.add(new Department(1001, "Sales"));
company.departments.add(new Department(1002, "Financial"));
// {"code":10,"departments":[[1001,"Sales"],[1002,"Financial"]]}
String text = JSON.toJSONString(commpany);
