我有以下配置:
@Bean
@Primary
public ObjectMapper objectMapper(Jackson2ObjectMapperBuilder builder) {
ObjectMapper objectMapper = builder.createXmlMapper(false).build();
objectMapper.configure(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS, false);
// objectMapper.configure(SerializationFeature.WRITE_DATE_TIMESTAMPS_AS_NANOSECONDS, false);
return objectMapper;
}
以及依赖关系:
ext {
springBootVersion = '1.5.2.RELEASE'
}
....
dependencies {
compile('org.springframework.boot:spring-boot-starter-websocket')
compile("org.springframework:spring-messaging")
compile('org.springframework.boot:spring-boot-starter-actuator')
compile('org.springframework.boot:spring-boot-starter-thymeleaf')
compile('org.springframework.boot:spring-boot-starter-validation')
compile('org.springframework.boot:spring-boot-starter-web')
compile group: 'net.jcip', name: 'jcip-annotations', version: '1.0'
compile ("com.fasterxml.jackson.datatype:jackson-datatype-jsr310")
testCompile('org.springframework.boot:spring-boot-starter-test')
}
我添加了以下控制器:
@PostMapping("/validation_test")
public String testValidation(@Valid @RequestBody ClientInputMessage clientInputMessage, BindingResult result) {
logger.info(Arrays.toString(result.getAllErrors().toArray()));
return "main";
}
public class ClientInputMessage {
@NotEmpty
private String num1;
@NotEmpty
private String num2;
@Past
private LocalDateTime date;
如果我像这样传递json:
{
"num1":"324",
"num2":123,
"date":"2014-01-01"
}
应用程序打印输出:
Failed to read HTTP message: org.springframework.http.converter.HttpMessageNotReadableException: Could not read document: Can not deserialize value of type java.time.LocalDateTime from String "2014-01-01": Text '2014-01-01' could not be parsed at index 10

最佳答案
原始答案:
java中的LocalDateTime不接受“2014-01-01”作为有效日期字符串.
一些额外的信息:
如果您实际上并不关心您的日期类型(LocalDate,OffsetDate,ZonedDate,…),您可以将其设为TemporalAccessor,然后使用DateTimeFormatter::parseBest来解析日期.
附:
字符串“2014-01-01T00:00:00”对LocalDateTime有效
