java - 如何使用Jackson ObjectMapper将多个数据转换为Pojo

Question

我想将以下字符串/JSONObject 转换为 POJO，

{"list":["\r\n{\r\n\"id\":\"1\",\r\n\"protocol\":\"udp\",\r\n\"srcPorts= \":\"3000-4000    \",\r\n\"destPorts\":\"1790-2000\"\r\n}","\r\n{\r\n\"id\":\"2\",\r\n    \"protocol\":\"tcp\",\r\n\"srcPorts\":\"3000-4000\",\r\n\"destPorts\":\"1790-2000    \"\r\n}"],"user":"\r\n{\r\n\"name\":\"John\",\r\n\"address\":\"x.x.x.x\",\r\n\"email     \":\"john@p.com\"\r\n}"}

如何使用 Jackson ObjectMapper 转换为 Pojo。 2个Pojo类如下。

上面字符串中的用户部分应映射到 java 文件 - User.java

public class User 
{
    private String name;

    private String address;

    private String email;

    public String getName()
    {
        return name;
    }

    public void setName(String name) 
    {
        this.name = name;
    }

    public String getAddress() 
    {
        return address;
    }

    public void setaddress(String Address) 
    {
        this.address = address;
    }

    public String getEmail()
    {
        return email;
    }

    public void setEmail(String email)
    {
        this.email = email;
    }   
}

上面字符串中的 List 部分应映射到 java 文件 - TestCase.java

public class TestCase 
{
    private String id;
    private String protocol;
    private String srcPorts;
    private String destPorts;

    public String getProtocol()
    {
        return protocol;
    }

    public void setProtocol(String protocol) 
    {
        this.protocol = protocol;
    }

    public String getSrcPorts() 
    {
        return srcPorts;
    }

    public void setSrcPorts(String srcPorts) 
    {
        this.srcPorts = srcPorts;
    }

    public String getDestPorts() 
    {
        return destPorts;
    }

    public void setDestPorts(String destPorts) 
    {
        this.destPorts = destPorts;
    }

    public String getID() 
    {
        return id;
    }

    public void setID(String id) 
    {
        this.id = id;
    }       
}

以下代码应该有帮助。

类 ParseJson{

私有(private)用户用户；
私有(private)测试用例测试用例；

//getter 和 setter 方法
}
//然后调用objectMapper -
String jsonString = "";//Json输入
ObjectMapper 映射器 = new ObjectMapper();
ParseJson parsedJson = mapper.readValue(jsonString, ParseJson.class);

用户 user = parsedJson.getUser();
TestCase testCase = parsedJson.getTestCase();
