Fastjson之BeanToArray的功能简介说明

BeanToArray:
   指将bean映射为json array数组 

class Mode {
   public int id;
   public int name;
}

Model model = new Model();
model.id = 1001;
model.name = "java265";

// {"id":1001,"name":"java265"}
String text_normal = JSON.toJSONString(model); 

// [1001,"java265"]
String text_beanToArray = JSON.toJSONString(model, SerializerFeature.BeanToArray); 

// support beanToArray & normal mode
JSON.parseObject(text_beanToArray, Feature.SupportArrayToBean); 

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); 

class Company {
     public int code;

     @JSONField(serialzeFeatures=SerializerFeature.BeanToArray, parseFeatures=Feature.SupportArrayToBean)
     public List<Department> departments = new ArrayList<Department>();
}
