Fastjson Bean转换为json Array简介说明

实现思路:
    只需在实体类上加入
	@JSONType(serialzeFeatures=SerializerFeature.BeanToArray, parseFeatures=Feature.SupportArrayToBean)
	注解即可实现Bean转换为Array的效果

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

Model model = new Model();
model.id = 88888;
model.name = "java265";

// {"id":88888,"name":"java265"}
String txt = JSON.toJSONString(model); 

// [88888,"java265"]
String str = JSON.toJSONString(model, SerializerFeature.BeanToArray); 

// support 
JSON.parseObject(str, 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 = 111;
company.departments.add(new Department(888, "dep1"));
company.departments.add(new Department(999, "dep2"));

// {"code"111,"departments":[[888,"dep1"],[999,"dep2"]]}
String text = JSON.toJSONString(commpany); 

class Company {
     public int code;

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