JSON字符串转成java的Map对象详细步骤

public class Element {
    private boolean checked;
    private String text;

    // 构造函数
    public Element() {}

    public boolean isChecked() {
        return checked;
    }

    public void setChecked(boolean checked) {
        this.checked = checked;
    }

    public String getText() {
        return text;
    }

    public void setText(String text) {
        this.text = text;
    }

    @Override
    public String toString() {
        return "Element{" +
                "checked=" + checked +
                ", text='" + text + '\'' +
                '}';
    }
}
