responseBody数据对象：
{

"username":"lvyuanj",
"password":"123456",

"enable":1,

方案一:
@Configuration
public class CommonConfig {
@Configuration
@ConditionalOnClass(ObjectMapper.class)
@AutoConfigureBefore(JacksonAutoConfiguration.class)
public class JacksonConfig {
@Bean
public Jackson2ObjectMapperBuilderCustomizer customizer() {
return builder -> {
builder.locale(Locale.CHINA);
builder.timeZone(TimeZone.getTimeZone(ZoneId.systemDefault()));
builder.simpleDateFormat(DatePattern.NORM_DATETIME_PATTERN);
builder.modules(new Java8TimeModule());
};
}
}
}
public class Java8TimeModule extends SimpleModule {
public Java8TimeModule() {
super(PackageVersion.VERSION);
this.addSerializer(LocalDateTime.class, new LocalDateTimeSerializer(DateTimeFormatter.ofPattern(DatePattern.NORM_DATETIME_PATTERN)));
this.addSerializer(LocalDate.class, new LocalDateSerializer(DateTimeFormatter.ofPattern(DatePattern.NORM_DATE_PATTERN)));
this.addSerializer(LocalTime.class, new LocalTimeSerializer(DateTimeFormatter.ofPattern(DatePattern.NORM_TIME_PATTERN)));
this.addDeserializer(LocalDateTime.class, new LocalDateTimeDeserializer(DateTimeFormatter.ofPattern(DatePattern.NORM_DATETIME_PATTERN)));
this.addDeserializer(LocalDate.class, new LocalDateDeserializer(DateTimeFormatter.ofPattern(DatePattern.NORM_DATE_PATTERN)));
this.addDeserializer(LocalTime.class, new LocalTimeDeserializer(DateTimeFormatter.ofPattern(DatePattern.NORM_TIME_PATTERN)));
}
}
方案二
@Configuration
public class UpmsMvcConfig extends WebMvcConfigurationSupport {
@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("/**")
.addResourceLocations("classpath:/static/")
.addResourceLocations("classpath:/templates/");
registry.addResourceHandler("swagger-ui.html").addResourceLocations(

}
/** 默认日期时间格式 */
public static final String DEFAULT_DATE_TIME_FORMAT = "yyyy-MM-dd HH:mm:ss";
/** 默认日期格式 */
public static final String DEFAULT_DATE_FORMAT = "yyyy-MM-dd";
/** 默认时间格式 */

@Bean
public ObjectMapper objectMapper(){
ObjectMapper objectMapper = new ObjectMapper();
objectMapper.disable(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS);
objectMapper.disable(DeserializationFeature.ADJUST_DATES_TO_CONTEXT_TIME_ZONE);
// 忽略json字符串中不识别的属性

// PrettyPrinter 格式化输出
objectMapper.configure(SerializationFeature.INDENT_OUTPUT, true);
// NULL不参与序列化
objectMapper.setSerializationInclusion(JsonInclude.Include.NON_NULL);
// 指定时区
objectMapper.setTimeZone(TimeZone.getTimeZone("GMT+8:00"));
// 日期类型字符串处理
objectMapper.setDateFormat(new SimpleDateFormat(DEFAULT_DATE_TIME_FORMAT));
//LocalDateTime系列序列化和反序列化模块，继承自jsr310，我们在这里修改了日期格式
JavaTimeModule javaTimeModule = new JavaTimeModule();
javaTimeModule.addSerializer(LocalDateTime.class,new LocalDateTimeSerializer(DateTimeFormatter.ofPattern(DEFAULT_DATE_TIME_FORMAT)));
javaTimeModule.addSerializer(LocalDate.class,new LocalDateSerializer(DateTimeFormatter.ofPattern(DEFAULT_DATE_FORMAT)));
javaTimeModule.addSerializer(LocalTime.class,new LocalTimeSerializer(DateTimeFormatter.ofPattern(DEFAULT_TIME_FORMAT)));
javaTimeModule.addDeserializer(LocalDateTime.class,new LocalDateTimeDeserializer(DateTimeFormatter.ofPattern(DEFAULT_DATE_TIME_FORMAT)));
javaTimeModule.addDeserializer(LocalDate.class,new LocalDateDeserializer(DateTimeFormatter.ofPattern(DEFAULT_DATE_FORMAT)));
javaTimeModule.addDeserializer(LocalTime.class,new LocalTimeDeserializer(DateTimeFormatter.ofPattern(DEFAULT_TIME_FORMAT)));
//Date序列化和反序列化
javaTimeModule.addSerializer(Date.class, new JsonSerializer<Date>() {
@Override
public void serialize(Date date, JsonGenerator jsonGenerator, SerializerProvider serializerProvider) throws IOException {
SimpleDateFormat formatter = new SimpleDateFormat(DEFAULT_DATE_TIME_FORMAT);
String formattedDate = formatter.format(date);
jsonGenerator.writeString(formattedDate);
}
});
javaTimeModule.addDeserializer(Date.class, new JsonDeserializer<Date>() {
@Override
public Date deserialize(JsonParser jsonParser, DeserializationContext deserializationContext) throws IOException, JsonProcessingException {
SimpleDateFormat format = new SimpleDateFormat(DEFAULT_DATE_TIME_FORMAT);
String date = jsonParser.getText();
try {
return format.parse(date);
} catch (ParseException e) {
throw new RuntimeException(e);
}
}
});
objectMapper.registerModule(javaTimeModule);
return objectMapper;
}
}
请求responseBody响应结果：
{
"id" : 1,
"username" : "test",
"password" : "123456",
"email" : "test@126.com",
"nickName" : "arvin",
"createTime" : "2020-09-06 22:23:18",
"loginTime" : "2020-09-10 20:44:42",
"enable" : 1
}
无论是Date类型，还是LocalDateTime类型
注：方案二注入@Bean ObjetMapper 需要放在 实现 WebMvcConfigurer的子类中。否则不生效。 个人倾向于方案一。
