I'm developing a web app created with JHipster v2.20.0. Using Eclipse 4.5.0 WTP as IDE.

The Spring configuration is annotation based.

I've just merged this pull with our code.

When I try to run the application inside Eclipse I get this exception:

[INFO] com.app.tenancy.hibernate.MyCurrentTenantIdentifierResolver - MyCurrentTenantIdentifierResolver.getTenantId(): Couldn't find Company/Tenant for the domain inventario, stopping serving the request

This is the UserManagementMapper class:

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);
    }
}

This is the UserManagementResource class:

        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();
    }
}

Lastly, the pom.xml file was not changed during this merge. The application was working properly before the merge.

It's probably some newbie question, but I've lost more hours trying to solve this than performing the merge.

Thanks in advance for any help!

回答1:

You should make sure that "target/generated-sources" is linked as a source folder in Eclipse.



回答2:

For IntelliJ (Gradle) users,

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

Make sure to assemble gradle after.

For maven User,

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



回答3:

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.



回答4:

I had the same problem with my JHipster project using Gradle. In Eclipse, I linked the "build\generated\source\apt\main" directory as source folder and the problem was solved.

  1. Right click your project and go to "Properties"
  2. Go to "Java Build Path" and look for "Source" tab
  3. Click on button "Link Source..."
  4. Browse for "build\generated\source\apt\main" directory
  5. You can leave the suggested name as it is
  6. Click finish

Now you can try to run your JHipster project, inside eclipse, as a Java Application and it will probably work.



回答5:

I started using intelliJ a few days ago. Enabling annotation processing (as suggested by Shree Krishna) works for me. it's documented on JHipster IDEA config page (https://www.jhipster.tech/configuring-ide-idea/). But the current documentation on this page is not explicit for new IntelliJ users like me.

Jhispter members should update their documentation by something more explicit like Shree Krishna's anwser (it will save lot of people from spending hours for fixing the problem). 

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