Java 简单 bean 与 json 互相转换

场景说明

最近在写一个服务，经常用到调别人接口得到json，然后需要转换为 指定bean,记录一下常用工具类

引入依赖

        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>fastjson</artifactId>
        </dependency>
        <dependency>
            <groupId>cn.hutool</groupId>
            <artifactId>hutool-all</artifactId>
        </dependency>

示例

bean 

@Data
public class User {
    private Integer id;
    private String name;
    private List<String> books;
}

转换

    @Test
    public void testjson() {
        User user = new User();
        user.setId(1001);
        user.setName("金庸");
        ArrayList<String> books = new ArrayList<>();
        books.add("飞");
        books.add("雪");
        books.add("连");
        books.add("天");
        books.add("射");
        books.add("白");
        books.add("
