我正在开发一个使用 JHipster v2.20.0 创建的网络应用程序。使用 Eclipse 4.5.0 WTP 作为 IDE。

Spring 配置是基于注解的。

我刚刚将这个拉取与我们的代码合并。

当我尝试在 Eclipse 中运行应用程序时，我得到了这个异常：

这是 UserManagementMapper 类：

package com.app.web.rest.mapper;

import java.util.List;
import java.util.Optional;

import javax.inject.Inject;

import org.mapstruct.Mapper;
import org.mapstruct.Mapping;
import org.mapstruct.MappingTarget;

import com.app.domain.User;
import com.app.service.UserService;
import com.app.web.rest.dto.UserManagementDTO;

@Mapper(componentModel = "spring", uses = {})
public abstract class UserManagementMapper {

    @Inject
    private UserService userService;

    public abstract UserManagementDTO userToUserManagementDTO(User user);
    public abstract List<UserManagementDTO> usersToUserManagementsDTO(List<User> users);

    @Mapping(target = "createdBy", ignore=true)
    @Mapping(target = "createdDate", ignore=true)
    @Mapping(target = "lastModifiedBy", ignore=true)
    @Mapping(target = "lastModifiedDate", ignore=true)
    @Mapping(target = "persistentTokens", ignore=true)
    @Mapping(target = "resetDate", ignore=true)
    @Mapping(target = "activationKey", ignore=true)
    @Mapping(target = "resetKey", ignore=true)
    @Mapping(target = "password", ignore=true)
    public abstract User updateUserFromDto(UserManagementDTO userManagementDTO, @MappingTarget User user);



    public User userManagementDTOToUser(UserManagementDTO userManagementDTO) {
        return  Optional.ofNullable(userService.getUserWithAuthorities(userManagementDTO.getId()))
            .map(user -> this.updateUserFromDto(userManagementDTO, user))
            .orElse(null);
    }
}

这是 UserManagementResource 类：

    @Transactional(readOnly = true)
    public ResponseEntity<List<UserManagementDTO>> getAll(@RequestParam(value = "page" , required = false) Integer offset,

        throws URISyntaxException {
        Page<User> page = userRepository.findAll(PaginationUtil.generatePageRequest(offset, limit));
        HttpHeaders headers = PaginationUtil.generatePaginationHttpHeaders(page, "/api/userManagement", offset, limit);
        return new ResponseEntity<>(page.getContent().stream()
                 .map(userManagementMapper::userToUserManagementDTO)
                 .collect(Collectors.toCollection(LinkedList::new)), headers, HttpStatus.OK);
    }

    /**
     * GET  /userManagement/:id -> get id user to manage.
     */
    @RequestMapping(value = "/userManagement/{id}",
            method = RequestMethod.GET,
            produces = MediaType.APPLICATION_JSON_VALUE)
    @Timed
    @RolesAllowed(AuthoritiesConstants.ADMIN)
    @Transactional(readOnly = true)
    ResponseEntity<UserManagementDTO> getUser(@PathVariable Long id) {
       log.debug("REST request to get User to manage : {}", id);
       return  Optional.ofNullable(userService.getUserWithAuthorities(id))
               .map(userManagementMapper::userToUserManagementDTO)
               .map(userManagementDTO -> new ResponseEntity<>(
                    userManagementDTO,
                    HttpStatus.OK))
               .orElse(new ResponseEntity<>(HttpStatus.NOT_FOUND));
    }

    /**
     * PUT  /userManagement -> Updates an existing user.
     */
    @RequestMapping(value = "/userManagement",
        method = RequestMethod.PUT,
        produces = MediaType.APPLICATION_JSON_VALUE)
    @Timed
    @RolesAllowed(AuthoritiesConstants.ADMIN)
    public ResponseEntity<Void> update(@RequestBody UserManagementDTO userManagementDTO) throws URISyntaxException {
        log.debug("REST request to update User : {}", userManagementDTO);
        if (userManagementDTO.getId() == null) {
            return ResponseEntity.badRequest().header("Failure", "You cannot create a new user").build();
        }
        User user = userManagementMapper.userManagementDTOToUser(userManagementDTO);
        userRepository.save(user);
        return ResponseEntity.ok().build();
    }
}

最后，在此合并期间 pom.xml 文件未更改。该应用程序在合并之前工作正常。

这可能是一些新手问题，但与执行合并相比，我在尝试解决这个问题上花费了更多时间。

提前感谢您的帮助！

您应该确保“target/generated-sources”链接为 Eclipse 中的源文件夹。

对于 IntelliJ (Gradle) 用户，

Settings-> Build, Execution, Deployment-> Compiler-> Annotation Processors->Enable annotation processing

确保assemble毕业后。

对于 Maven 用户，

Build tools-> Maven-> Importing->Generated Sources folder

从用于设置 Eclipse 的 JHipster 文档页面：

将 apt 生成的源文件夹添加到构建路径

当使用 buildship gradles 默认输出文件夹被过滤并且在你的工作空间中不可见。因此，您需要将其从 eclipse 的资源过滤器设置中删除。

  • 右键单击您的项目并选择Properties
  • 选择Resources
  • 删除条目build
  • 选择Java Build Path
  • 点击Add Folder...
  • 检查路径build/generated/source/apt/main

当通过 eclipse 运行 JHipster 时，确保新的源文件夹包含正确生成的映射器实现。

我在使用 Gradle 的 JHipster 项目中遇到了同样的问题。在 Eclipse 中，我将“build\generated\source\apt\main”目录链接为源文件夹，问题就解决了。

  1. 右键单击您的项目并转到“属性”
  2. 转到“Java Build Path”并查找“Source”选项卡
  3. 单击“链接源...”按钮
  4. 浏览“build\generated\source\apt\main”目录
  5. 您可以保留建议的名称
  6. 点击完成

现在您可以尝试在 Eclipse 中将您的 JHipster 项目作为 Java 应用程序运行，它可能会工作。

几天前我开始使用 IntelliJ。启用注释处理（由 Shree Krishna 建议）对我有用。它记录在 JHipster IDEA 配置页面 ( https://www.jhipster.tech/configuring-ide-idea/ )。但是此页面上的当前文档对于像我这样的新 IntelliJ 用户并不明确。

Jhispter 成员应该通过更明确的方式来更新他们的文档，比如 Shree Krishna 的 anwser（这将节省很多人花费数小时来解决问题的时间）。

Settings -> Build, Execution, Deployment -> Compiler -> Annotation Processors -> Enable annotation processing

虽然不使用 JHipster，但我在使用常规 spring boot 时遇到了同样的问题。

问题是，在 maven 注释处理器路径插件上，我已经为 MapStruct 路径指定了注释配置，但 maven 仍然会给出 unstaisfied 依赖错误。正在生成 mapstruct 映射器的实现。我生成的注释文件夹也存在于类路径中。还是没用。

修复？这是由龙目岛项目引起的。我没有在我的代码中使用项目 lombok，但它仍然最终出现在我的依赖关系树上。我也在 pom.xml 文件中为 lombok 指定了注解配置路径，最后，该死的东西被打包了。

升级到 Intellij 2020.3 后我遇到了同样的问题

这里的解决方案对我有用

-Djps.track.ap.dependencies=false

应该添加到文件 | 设置 | 构建、执行、部署 | 编译器 | 用户本地构建过程 VM 选项字段。

对于 Eclipse，安装插件 m2e-apt 并确保将“target/generated-sources”链接为源文件夹
