使用Lombok@Builder注释的多个构造函数会导致问题吗?

这是我的第一个问题,所以请随时纠正我在写这个问题时遗漏的任何内容:)

我在将@Bulider与我的DTO对象一起使用时遇到了问题。 我有一个抽象类” 事件DTO “由类类型继承” CreateTaskLogDTO ".

我在两个班上都有两个构造函数。内部施工人员 CreateTaskLogDTO 继承内部的那些 事件DTO .

奇怪的是,构造函数用
@构建器(builderMethodName=“buildWithSpecificParamsNoID”) 工作正常,但与 @构建器(builderMethodName=“buildWithOperationStringID”) 无法实例化以下字段:字符串操作字符串、长id

我试图运行测试代码来正确识别问题。

这是不起作用的测试(使用 buildWithOperationStringID 建设者法) 它无法设置字段:Id和OperationString。其他一切都设置得很好。

   @Test
    void createTaskLogDTO_builder_withID_test(){
        String operationString = "Task1";
        LocalDateTime now = LocalDateTime.now();

        when(mockTask.getTaskName()).thenReturn("Task1");
        when(mockUser.getNickname()).thenReturn("User1");
        when(mockGroup.getGroupName()).thenReturn("Group1");

        CreateTaskLogDTO createTaskLogDTO =  CreateTaskLogDTO.buildWithOperationStringID()
                .id(1L)
                .task(mockTask)
                .user(mockUser)
                .group(mockGroup)
                .operationString(operationString)
                .operationTime(now)
                .operationTypeEnum(OperationType.CREATE_TASK)
                .build();

        assertEquals(createTaskLogDTO.getId(),1L);
        assertEquals(createTaskLogDTO.getTask().getTaskName(),mockTask.getTaskName());
        assertEquals(createTaskLogDTO.getUser().getNickname(),mockUser.getNickname());
        assertEquals(createTaskLogDTO.getGroup().getGroupName(),mockGroup.getGroupName());
        assertEquals(createTaskLogDTO.getOperationTime(),now);
        assertEquals(createTaskLogDTO.getOperationTypeEnum(),OperationType.CREATE_TASK);
        assertEquals(operationString,createTaskLogDTO.getOperationString());
    }

这是对构建器方法有效性的测试(buildWithSpecificParamsNoID) 它正确设置了所有字段。

    @Test
    void createTaskLogDTO_build_withoutID_test(){
        when(mockTask.getTaskName()).thenReturn("Task1");
        when(mockUser.getNickname()).thenReturn("User1");
        when(mockGroup.getGroupName()).thenReturn("Group1");

        String operationString = "Task1";
        LocalDateTime now = LocalDateTime.now();

        CreateTaskLogDTO createTaskLogDTO = CreateTaskLogDTO.buildWithSpecificParamsNoID()
                .task(mockTask)
                .user(mockUser)
                .group(mockGroup)
                .operationTime(now)
                .operationTypeEnum(OperationType.CREATE_TASK)
                .newTaskName(mockTask.getTaskName())
                .build();

        assertEquals(createTaskLogDTO.getTask().getTaskName(),mockTask.getTaskName());
        assertEquals(createTaskLogDTO.getUser().getNickname(),mockUser.getNickname());
        assertEquals(createTaskLogDTO.getGroup().getGroupName(),mockGroup.getGroupName());
        assertEquals(createTaskLogDTO.getOperationTime(),now);
        assertEquals(createTaskLogDTO.getOperationTypeEnum(),OperationType.CREATE_TASK);
        assertEquals(operationString,createTaskLogDTO.getOperationString());
        assertEquals(mockTask.getTaskName(),createTaskLogDTO.getNewTaskName());

    }
