#[derive(Serialize, Default, Deserialize, Debug, Clone)]
pub struct Person {
    pub id: i64,
    pub name: String,
    pub age: u16,
    pub active: bool,
}
// 普通实体
//impl_base_entity!(Person);
impl BaseEntity for Person {}

测试用例：to_json

#[test]
fn test_013_to_json() {
    let mut person = (*dbexample::find_bean_person().unwrap()).clone();
    person.name = "leijmdas".to_string();
    rulog::info2("person:", person.to_json().as_str());
  
}

结果：person: {
  "id": 0,
  "name": "leijmdas",
  "age": 0,
  "active": false
}

测试用例：from_json

#[test]
fn test_14_from_json() {
    let mut person = dbexample::find_bean_person().unwrap().get_self();
    // 从 JSON 字符串反序列化回结构体
    let json = r#"
            {
                "id": 10,
                "name": "songlei",
                "age": 10,
                "active": true
            }
    "#;
    let pnew = person.from_json(json.to_string());
    rulog::info2("pnew:", pnew.to_json().as_str());
}

测试结果：

pnew: {
  "id": 10,
  "name": "songlei",
  "age": 10,
  "active": true
}
