一、java string 类型转list实体类且忽略实体类中没有的字段

1、xml 添加依赖

<dependency>
    <groupId>com.google.code.gson</groupId>
    <artifactId>gson</artifactId>
    <version>2.8.8</version>
</dependency>

2、java代码

import com.google.gson.Gson;
import com.google.gson.reflect.TypeToken;
import java.lang.reflect.Type;
import java.util.List;
 
public class Main {
    public static void main(String[] args) {
        String json = "[{\"name\":\"John\", \"age\":30}]";
        Gson gson = new Gson();
        Type listType = new TypeToken<List<Person>>(){}.getType();
        List<Person> people = gson.fromJson(json, listType);
        people.forEach(System.out::println);
    }
}
 
class Person {
    private String name;
    private int age;
    // getters and setters
    @Override
    public String toString() {
        return "Person{name='" + name + "', age=" + age + '}';
    }
}
