Java将JSON数组转为list

可以使用Jackson库的ObjectMapper类中的readValue方法将JSON数组转为List对象。具体实现可以参考以下代码：

import com.fasterxml.jackson.core.type.TypeReference;
import com.fasterxml.jackson.databind.ObjectMapper;

import java.util.List;

public class JsonToList {
    public static void main(String[] args) throws Exception {
        String jsonStr = "[{\"id\":1,\"name\":\"John\"},{\"id\":2,\"name\":\"Mike\"},{\"id\":3,\"name\":\"Sarah\"}]";
        ObjectMapper objectMapper = new ObjectMapper();
        List<Person> personList = objectMapper.readValue(jsonStr, new TypeReference<List<Person>>() {});
        System.out.println(personList);
    }

    static class Person {
        private int id;
        private String name;

        public int getId() {
            return id;
        }

        public void setId(int id) {
            this.id = id;
        }

        public String getName() {
            return name;
        }

        public void setName(String name) {
            this.name = name;
        }

        @Override
        public String toString() {
            return "Person{" +
                    "id=" + id +
                    ", name='" + name + '\'' +
                    '}';
        }
    }
}
