以下是我试图使用objectMapper反序列化的json

{
  "myStringBuilder" : "mine"
}

以下是POJO

public class MyPojo {

    private StringBuilder myStringBuilder;

    public MyPojo() {

    }

    public MyPojo(String myStringBuilder) {
        this.myStringBuilder = new StringBuilder(myStringBuilder);
    }

    public StringBuilder getMyStringBuilder() {
        return myStringBuilder;
    }

    public void setMyStringBuilder(StringBuilder myStringBuilder) {
        this.myStringBuilder = myStringBuilder;
    }

}

在反序列化期间面临以下问题 -

com.fasterxml.jackson.databind.JsonMappingException：无法从String值（'mine'）实例化类型[simple type，class java.lang.StringBuilder]的值; [Source：{“myStringBuilder”：“mine”}中没有单字符串构造函数/工厂方法; line：2，column：3]（通过引用链：MyPojo [“myStringBuilder”]）

请帮我解决这个问题 .
