依赖
<dependency> <groupId>cn.hutool</groupId> <artifactId>hutool-json</artifactId> <version>5.8.10</version> </dependency>
为了避免字符串中各种转义字符，我们采用直接从文件中读取json字符串的方式
data.json
{ "name": "Tom", "age": 23 }
实体类
package com.github.mouday.demo; public class User { private String name; private Integer age; public User(String name, Integer age) { this.name = name; this.age = age; } public String getName() { return name; } public void setName(String name) { this.name = name; } public Integer getAge() { return age; } public void setAge(Integer age) { this.age = age; } }
使用示例
package com.github.mouday.demo; import cn.hutool.json.JSONObject; import cn.hutool.json.JSONUtil; import java.io.File; import java.nio.charset.Charset; public class Demo { public static void main(String[] args) { JSONObject json = JSONUtil.readJSONObject(new File("./data.json"), Charset.forName("utf-8")); User user = json.toBean(User.class); System.out.println(user.getName()); // Tom System.out.println(user.getAge()); // 23 } }
