Mapstruct生成的类没有被Spring在JHipster Web应用程序中注入

标签： jhipster mapstruct

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配置是基于注释的。

我刚刚将this pull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：

package com.app.web.rest;

@RestController

    private final Logger log = LoggerFactory.getLogger(UserManagementResource.class);

    @Inject
    private UserRepository userRepository;

    @Autowired
    private UserManagementMapper userManagementMapper;

    /**
     * GET  /userManagement -> get all users to manage.
     */
    @RequestMapping(value = "/userManagement",
        method = RequestMethod.GET,
        produces = MediaType.APPLICATION_JSON_VALUE)
    @Timed
    @RolesAllowed(AuthoritiesConstants.ADMIN)
    @Transactional(readOnly = true)
    public ResponseEntity<List<UserManagementDTO>> getAll(@RequestParam(value = "page" , required = false) Integer offset,
                                                         @RequestParam(value = "per_page", required = false) Integer limit)
        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，在此合并期间未更改pom.xml文件。该应用程序在合并之前正常工作。

这可能是一些新手问题，但是我尝试解决这个问题的时间比执行合并还要多。

提前感谢您的帮助！

你应该确保＆＃34; target / generated-sources＆＃34;在Eclipse中链接为源文件夹。

答案 1 :(得分：3)

对于IntelliJ（Gradle）用户，

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

请务必在之后assemble进行摇动。

对于maven用户，

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

答案 2 :(得分：2)

From the JHipster documentation page for setting up Eclipse:

Add apt generated source folder to build path

When using buildship gradles default outputfolder is filtered and not visible in your workspace. Therefore you need to remove it from eclipse’s resource filter setting.

  • Right click on your project and select Properties
  • Select Resources
  • Remove the entry build
  • Select Java Build Path
  • Click Add Folder...
  • Check the path build/generated/source/apt/main

Make sure the new source folder contains the correctly generated mapper implementations when running JHipster via eclipse.

答案 3 :(得分：0)

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

  1. 右键单击您的项目，然后转到“属性”
  2. 转到“Java Build Path”并查找“Source”选项卡
  3. 点击“链接来源...”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

    7. 现在你可以尝试在eclipse中运行你的JHipster项目作为Java应用程序，它可能会工作。

答案 4 :(得分：0)

几天前，我开始使用intelliJ。 启用注释处理（如Shree Krishna所建议）对我有效。 它记录在JHipster IDEA配置页面（https://www.jhipster.tech/configuring-ide-idea/）上。但是此页面上的当前文档对于像我这样的新IntelliJ用户而言不是明确的。

Jhispter成员应该使用更明确的内容（例如Shree Krishna的anwser）来更新其文档（这将使很多人不必花费大量时间来解决问题）。 

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

答案 5 :(得分：0)

虽然不使用JHipster，但在使用常规的Spring Boot时遇到了相同的问题。

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，但是maven仍然会给出未解决的依赖性错误。正在生成mapstruct映射器的实现。我的生成的注释文件夹也存在于类路径中。还是没用。

解决办法？这是由龙目岛项目引起的。我在代码中没有使用过项目lombok，但是它仍然以依赖树结尾。我还为lombok在pom.xml文件上指定了注释配置路径，最后，该死的东西被打包了。

答案 6 :(得分：0)

我在升级到 Intellij 2020.3 后遇到了同样的问题

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。
