场景说明

比如我们想打印返回参数的具体情况，如果里面有枚举类型，打印的参数不完整。

@Getter
@Setter
@ToString
public class ResultResponse {

    private String name;

    private Integer age;

    private ResultEnum resultEnum;

}

public enum ResultEnum {

    SUCCESS("0000", "成功"),
    FAIL("0001", "失败"),
    EXIST("0002", "已存在"),
    SYS_ERROR("9999", "系统异常");
    private String code;
    private String msg;

    ResultEnum(String code, String msg) {
        this.code = code;
        this.msg = msg;
    }

    public String getCode() {
        return code;
    }

    public void setCode(String code) {
        this.code = code;
    }

    public String getMsg() {
        return msg;
    }

    public void setMsg(String msg) {
        this.msg = msg;
    }

}

默认序列化方式

public class MainTest {

    public static void main(String[] args) {
        ResultResponse resultResponse = new ResultResponse();
        resultResponse.setAge(11);
        resultResponse.setName("张三");
        resultResponse.setResultEnum(ResultEnum.SUCCESS);
        System.out.println(JSONObject.toJSONString(resultResponse));
    }

}

运行结果：{"age":11,"name":"张三","resultEnum":"SUCCESS"}，并不是我想要的结果，枚举类型属性没打印出来

设置枚举序列化

public class MainTest {

    public static void main(String[] args) {
        ResultResponse resultResponse = new ResultResponse();
        resultResponse.setAge(11);
        resultResponse.setName("张三");
        resultResponse.setResultEnum(ResultEnum.SUCCESS);

        SerializeConfig config = new SerializeConfig();
        config.configEnumAsJavaBean(ResultEnum.class);

        System.out.println(JSONObject.toJSONString(resultResponse, config));
    }

}

运行结果：{"age":11,"name":"张三","resultEnum":{"code":"0000","msg":"成功"}}
