Java DTO测试始终运行null

Java DTO测试始终运行null,java,json,unit-testing,Java,Json,Unit Testing,我正在尝试实现DTO测试,因为它在测试中失败 我通过实现JSON数据提出了以下解决方案 但它总是返回null,而不是序列化的JSON对象 你知道吗 或者您是否推荐其他方法来测试DTO类 AccountBranchDto.java package az.iba.ms.account.dto.model; import com.fasterxml.jackson.annotation.JsonIgnoreProperties; import com.fasterxml.jackson.annota

我正在尝试实现DTO测试,因为它在测试中失败

我通过实现JSON数据提出了以下解决方案

但它总是返回null,而不是序列化的JSON对象

你知道吗

或者您是否推荐其他方法来测试DTO类
