Java中的JSON名值对解析

我有以下JSON结构，我想将其解析为Java对象。是否有我可以使用的现有库，或者我应该编写自定义代码进行解析。下面是示例json结构和java类

JSON:

Java对象：

class Hierarchy {
    String solutionId;
    String groupCode;
    KeyInfo keyInfo;

    public String getSolutionId() {
        return solutionId;
    }

    public void setSolutionId(String solutionId) {
        this.solutionId = solutionId;
    }

    public String getGroupCode() {
        return groupCode;
    }

    public void setGroupCode(String groupCode) {
        this.groupCode = groupCode;
    }

    public KeyInfo getKeyInfo() {
        return keyInfo;
    }

    public void setKeyInfo(KeyInfo keyInfo) {
        this.keyInfo = keyInfo;
    }
}

class KeyInfo {
    String customerName;
    String orderActionType;

    public String getCustomerName() {
        return customerName;
    }

    public void setCustomerName(String customerName) {
        this.customerName = customerName;
    }

    public String getOrderActionType() {
        return orderActionType;
    }

    public void setOrderActionType(String orderActionType) {
        this.orderActionType = orderActionType;
    }
}

使用

定义Pojo

无Pojo编辑：

现在，您可以使用名称和值…

要求我们推荐或查找书籍、工具、软件库、教程或其他非现场资源的问题对于堆栈溢出来说都是离题的，因为它们往往会吸引固执己见的答案和垃圾邮件。相反，请描述问题以及迄今为止为解决问题所做的工作。请参考此链接。非常好的例子第五个是给你们的。看一看，这是离题的，但作为线索，谷歌杰克逊或GSON，但我应该写自定义代码，从Pojo转换到层次类。。我想避免那样。。

class Hierarchy {
    String solutionId;
    String groupCode;
    KeyInfo keyInfo;

    public String getSolutionId() {
        return solutionId;
    }

    public void setSolutionId(String solutionId) {
        this.solutionId = solutionId;
    }

    public String getGroupCode() {
        return groupCode;
    }

    public void setGroupCode(String groupCode) {
        this.groupCode = groupCode;
    }

    public KeyInfo getKeyInfo() {
        return keyInfo;
    }

    public void setKeyInfo(KeyInfo keyInfo) {
        this.keyInfo = keyInfo;
    }
}

class KeyInfo {
    String customerName;
    String orderActionType;

    public String getCustomerName() {
        return customerName;
    }

    public void setCustomerName(String customerName) {
        this.customerName = customerName;
    }

    public String getOrderActionType() {
        return orderActionType;
    }

    public void setOrderActionType(String orderActionType) {
        this.orderActionType = orderActionType;
    }
}

class Pojo {

    @Override
    public String toString() {
        return "Pojo [name=" + name + ", value=" + value + "]";
    }

    private String name;
    private List<Value> value;
}

class Value {

    private String name;
    private String value;

    @Override
    public String toString() {
        return "Value [name=" + name + ", value=" + value + "]";
    }

}
