有没有办法使用打字稿生成带有 40 个随机符号的随机字符串？
我正在尝试为数据库表实现正确的搜索功能。我尝试了这种方法：
控制器：
@GetMapping
public Page<TransactionDTO> find(TransactionFilterDTO filter, Pageable page) {
return searchRepository
.findTransactionsByFilter(mapper.toFilter(filter), page)
.map(mapper::toDTO);
}
Filer DTO：
public class TransactionFilterDTO {
private String name;
private Integer id;
@DateTimeFormat(iso = DateTimeFormat.ISO.DATE_TIME)
private LocalDateTime from;
@DateTimeFormat(iso = DateTimeFormat.ISO.DATE_TIME)
private LocalDateTime to;
... // getters and setter
}
搜索实现：
@Repository
public class TransactionSearchRepositoryImpl implements TransactionSearchRepository {
@Autowired
private TransactionRepository transactionRepository;
@Autowired
private TransactionSpecification specification;
@Override
public Page<Transaction> findTransactionsByFilter(TransactionFilter filter, @Nullable Pageable page) {
List<Transaction> transactions = transactionRepository
.findAll(specification.getFilter(filter));
int totalCount = transactions.size(); …我正在尝试实现这个 JUnit 代码：
private BinlistsService binlistsService = Mockito.mock(BinlistsService.class);
@Mock
Optional<BinLists> binList = null;
@BeforeEach
public void beforeEachTest() throws IOException {
BinLists binLists = new BinLists();
binLists.setId(1);
....
binList = Optional.of(binLists);
}
@Test
public void testBinCountryCheckFilterImpl() {
when(binlistsService.findByName(anyString())).thenReturn(binList);
}
但我得到这个错误堆栈：
org.mockito.exceptions.base.MockitoException:
Cannot mock/spy class java.util.Optional
Mockito cannot mock/spy because :
- final class
at org.data
你知道我该如何解决这个问题吗？
我想配置 Spring Boot 以使用 2 个 JNDI 数据源。我试过这个配置：
