Add alias symbol to class variable in Java-CodePudding

I am having a requirement to develop a JSON formatted data to pass to our 3rd party API vendor. One of the parameters require the variable to have alias symbol in front, but I am unsure the best way to put it.

JSON Example

"Test": [
            {
                "name": "1",
                "@type": "2"
            }
        ],

JAVA test class

public class Test
{
    private String name;
    private String type;
    
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    
    public String getType() {
        return type;
    }
    public void setType(String type) {
        this.type = type;
    }
}

How do I have the "@" symbol in front of the "type" variable? Any help is greatly appreciated.

CodePudding user response：

Assuming you have that weird requirement (which makes no sense to me) you can always change the name of a field that is serialized to JSON by using the JsonProperty annotation (assuming you are using Jackson of course).

To achieve something like that, simply do something in the lines of:

public class Test {

    private String name;
    public String getName() {
        return name;
    }

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

    @JsonProperty("@type")
    private String type;
    public String getType() {
        return type;
    }

    public void setType(String type) {
        this.type = type;
    }

}
