具有Mock身份验证的单元测试：ProviderNotFoundException

Question

我有类似Spring Boot的服务

@GetMapping("/myService")
@PreAuthorize("hasAnyAuthority('EDIT')")
public String savePermissionList(...) {
    ....
    final Authentication authentication = SecurityContextHolder.getContext().getAuthentication();
    Integer roleId = null;
    if (authentication.getDetails() instanceof MyRole) {
        roleId = (((MyRole) authentication.getDetails()).getId());
    }
}

我需要此服务来保存以后需要的权限列表。由于我想测试其他服务，因此我需要在测试的一开始就运行此方法。我以为我可以使用这样的东西：

@Before
public void setUp() throws Exception {
    role1 = new MyRole(....)

    MockitoAnnotations.initMocks(this);

    final Authentication authentication = mock(Authentication.class);
    final SecurityContext securityContext = mock(SecurityContext.class);
    when(securityContext.getAuthentication()).thenReturn(authentication);
    SecurityContextHolder.setContext(securityContext);

    when(authentication.getDetails()).thenReturn(role1);
    final ArrayList<GrantedAuthority> authorities = new ArrayList<>();
    authorities.add(new SimpleGrantedAuthority("EDIT"));
    when((List<GrantedAuthority>) authentication.getAuthorities()).thenReturn(authorities);
    ...
    savePermissionList(...); 

但是我面临的问题是错误消息：

org.springframework.security.authentication.ProviderNotFoundException: No AuthenticationProvider found for org.springframework.security.core.Authentication$MockitoMock$1249720784
