当我尝试实现自己的映射时，我在使用 MapStruct 版本 1.4.1 时遇到问题。这是我写的代码：

package com.kucazdravlja.user.mappers;

import com.kucazdravlja.user.dto.NoticeBoardDto;
import com.kucazdravlja.user.entities.NoticeBoard;
import com.kucazdravlja.user.entities.NoticeBoardStatus;
import org.mapstruct.Mapper;
import org.mapstruct.Mapping;
import org.mapstruct.Named;

import java.util.Objects;

@Mapper(uses = {BaseJournalMapper.class})
public interface NoticeBoardMapper {

    @Mapping(source = "status", target = "status", qualifiedByName = "getNoticeBoardStatusName")
    NoticeBoard dtoToEntity(NoticeBoardDto noticeBoardDto);

    @Mapping(source = "status", target = "status", qualifiedByName = "getNoticeBoardStatusDescription")
    NoticeBoardDto entityToDto(NoticeBoard noticeBoard);

    @Named("getNoticeBoardStatusDescription")
    static String getNoticeBoardStatusDescriptionConverter(NoticeBoard noticeBoard) {
        return Objects.requireNonNull(NoticeBoardStatus.findByName(noticeBoard.getStatus())).getDescription();
    }

    @Named("getNoticeBoardStatusName")
    static String getNoticeBoardStatusNameConverter(NoticeBoardDto noticeBoardDto) {
        return Objects.requireNonNull(NoticeBoardStatus.findByName(noticeBoardDto.getStatus())).name();
    }
}

运行应用程序时它崩溃并给出错误

Error:(15, 5) java: Qualifier error. No method found …

关于mapStruct的问题。我有这样的情况：我从基本实体扩展类，但不确定如何映射它。这是我的案例。

基础实体：

public class BaseEntity {
    @Id
    @GeneratedValue(strategy = GenerationType.SEQUENCE)
    @Column(name = "id")
    private Long id;
}

基数为：

public class BaseDto {

    private Long id;
}

用户实体：

public class User extends BaseEntity {
    private String name;
    private String lastName;
    private String username;
    private String password;
    private String profilePicturePath;
}

用户D至：

public class UserDto extends BaseDto {
    private String name;
    private String lastName;
    private String username;
    private String password;
    private String profilePicturePath;
}

映射器是这样的：

@Mapper(uses = {BaseMapper.class})
public interface UserMapper { …

我已经开始学习 Sleuth，但我陷入了日志配置。

我有这个配置：

    <?xml version="1.0" encoding="UTF-8"?>\n<configuration>\n    <include resource="org/springframework/boot/logging/logback/defaults.xml"/>\n    \xe2\x80\x8b\n    <springProperty scope="context" name="springAppName" source="spring.application.name"/>\n    <!-- Example for logging into the build folder of your project -->\n    <property name="LOG_FILE" value="C://tmp//test"/>\xe2\x80\x8b\n\n    <property name="CONSOLE_LOG_PATTERN"\n              value="%clr(%d{yyyy-MM-dd HH:mm:ss.SSS}){faint} %clr(${LOG_LEVEL_PATTERN:-%5p}) %clr([${springAppName:-},%X{X-B3-TraceId:-},%X{X-B3-SpanId:-},%X{X-Span-Export:-}]){yellow} %clr(${PID:- }){magenta} %clr(---){faint} %clr([%15.15t]){faint} %clr(%-40.40logger{39}){cyan} %clr(:){faint} %m%n${LOG_EXCEPTION_CONVERSION_WORD:-%wEx}"/>\n\n    <!-- Appender to log to console -->\n    <appender name="console" class="ch.qos.logback.core.ConsoleAppender">\n        <filter class="ch.qos.logback.classic.filter.ThresholdFilter">\n            <level>INFO</level>\n        </filter>\n        <encoder>\n            <pattern>${CONSOLE_LOG_PATTERN}</pattern>\n            <charset>utf8</charset>\n        </encoder>\n    </appender>\n    \xe2\x80\x8b\n    <!-- Appender to log to file in a JSON format -->\n    <appender name="logstash" class="ch.qos.logback.core.rolling.RollingFileAppender">\n        <file>${LOG_FILE}.json</file>\n        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">\n …
