高级json字符串到java对象的处理和转换

我知道使用Jackson object mapper包将JSON字符串转换为JAVA对象。 假设我有下面提到的高级Json字符串。是否可以将其转换为Java对象

{
    "a": 123123,
    "b":true,
    "cList":[{
        "c1": "valuec1",
        "c2": "valuec2",
        "c3": "valuec3"
        },
        {
        "c1": "valuec4",
        "c2": "valuec5",
        "c3": "valuec6"
        }]
}

是的，为精确映射创建POJO，您可以使用相同的对象映射来完成。。。克莱斯特怎么样？是否需要声明为列表？？？仅供参考，这可能会有所帮助

public class Codebeautify {
private float a;
private boolean b;
ArrayList < Object > cList = new ArrayList < Object > ();


// Getter Methods 

public float getA() {
    return a;
}

public boolean getB() {
    return b;
}

// Setter Methods 

public void setA(float a) {
    this.a = a;
}

public void setB(boolean b) {
    this.b = b;
}
}

class Example {

    public int a;
    public boolean b;
    public List<Exmaple1> cList;
    @Override
    public String toString() {
        return "Example [a=" + a + ", flag=" + b + ", e1=" + cList + "]";
    }

}

    class Exmaple1 {
    public String c1;
    public String c2;
    public String c3;
    public String getC1() {
        return c1;
    }
    public void setC1(String c1) {
        this.c1 = c1;
    }
    public String getC2() {

    ObjectMapper objectMapper = new ObjectMapper();
