Mockito verify invocation error

I would have a problem with the junit tests with mockito. when I try to verify a service I get the error: "Actual invocation has different arguments"

Model:

@Entity
@Table(name = "projects")
public class Project {

    @Id
    @GeneratedValue(generator="increment")
    @GenericGenerator(name="increment", strategy = "increment")
    @Column(name = "id_project")
    private Long id;

    @Column(name = "project_name")
    private String name;

    @JsonInclude(value = Include.NON_NULL)
    @Column(name = "project_language")  
    private String language;

    @Temporal(TemporalType.DATE)
    @JsonFormat(shape = JsonFormat.Shape.STRING, pattern = "dd-MM-yyyy")
    @Column(name = "start_date")
    private Date start_date;

    @Temporal(TemporalType.DATE)
    @JsonFormat(shape = JsonFormat.Shape.STRING, pattern = "dd-MM-yyyy")
    @Column(name = "end_date")
    private Date end_date;

    @Transient
    @JsonIgnoreProperties
    private Long id_user;

    @ManyToOne
    @NotFound(action = NotFoundAction.IGNORE)
    @JoinColumn(name = "id_content_manager")
    private User contentManager;

    @Transient
    private Long id_license;

    @OneToOne
    @NotFound(action = NotFoundAction.IGNORE)
    @JoinColumn(name = "id_license")
    private License license;

    @OneToMany
    @LazyCollection(LazyCollectionOption.FALSE)
    @NotFound(action = NotFoundAction.IGNORE)
    @JoinTable(name = "team", joinColumns = { @JoinColumn(name = "id_project") }, inverseJoinColumns = { @JoinColumn(name = "id_user") })
    private List<User> team;

    @OneToOne
    @NotFound(action = NotFoundAction.IGNORE)
    @JoinColumn(name = "id_policy")
    private ProjectPolicy policy;

    @OneToMany
    @LazyCollection(LazyCollectionOption.FALSE)
    @NotFound(action = NotFoundAction.IGNORE)
    @JoinTable(name = "project2tag", joinColumns = { @JoinColumn(name = "id_project") }, inverseJoinColumns = { @JoinColumn(name = "id_tag") })
    private List<Tag> tags = new ArrayList<Tag>();
...

Controller:

@RequestMapping(value = "/", method = RequestMethod.PUT, consumes = "application/json" , produces = "application/json")
    public @ResponseBody ResponseEntity<BaseModel> edit( @RequestHeader(value="Authorization") String token, @RequestBody Project project, Locale locale) throws ParseException{
        if(!SecurityUtil.validateToken(token)) {
            return new ResponseEntity<BaseModel>(new BaseModel("error", MessageHandler.returnMessage("invalid_token", locale)), HttpStatus.UNAUTHORIZED);
        }
        if(project.getId() == null ) {
            return new ResponseEntity<BaseModel>(new BaseModel("error", "Bad request"), HttpStatus.BAD_REQUEST);
        }

        Project projecttmp = projectDao.findById(project.getId());
        if( projecttmp != null) {
            project.setContentManager(projecttmp.getContentManager());
            project.setLicense(projecttmp.getLicense());
            project.setPolicy(projecttmp.getPolicy());
            project.setTags(projecttmp.getTags());
            project.setTeam(projecttmp.getTeam());
            projectDao.editProject(project);
            return new ResponseEntity<BaseModel>(new BaseModel("ok", "ok"), HttpStatus.OK);
        }

        return new ResponseEntity<BaseModel>(new BaseModel("error", MessageHandler.returnMessage("internal_error", locale)), HttpStatus.INTERNAL_SERVER_ERROR);
    }

and the test with failure:

@Test
    public void updateProject() throws Exception{
        Project project = new Project();
        project.setId(new Long(22));

        when(projectService.findById(anyLong())).thenReturn(project);

        String json = mapper.writeValueAsString(project);

        logger.info(json);

        doNothing().when(projectService).editProject(any(Project.class));

        mockMvc.perform(put("/project/")
                .header("Authorization", TOKEN)
                .accept(MediaType.APPLICATION_JSON)
                .content(json)
                .contentType(MediaType.APPLICATION_JSON))
            .andExpect(status().isOk())
            .andDo(MockMvcResultHandlers.print());

        verify(projectService, times(1)).findById(eq(project.getId()));
        verify(projectService, times(1)).editProject(eq(project));
    }

When i can try to run the test the result is "Actual invocation has different arguments" someone who can help me?

Mockito.eq() compares using .equals() method. You should override this method (and hashCode as well) in Project class, and make comparison by id. For example:

@Override
public boolean equals(Object o) {
    if (this == o) return true;
    if (o == null || getClass() != o.getClass()) return false;

    Project project = (Project) o;

    return getId() != null ? getId().equals(project.getId()) : project.getId() == null;
}

@Override
public int hashCode() {
    return getId() != null ? getId().hashCode() : 0;
}
