SpringBoot+MyBatis Plus对Map中Date格式转换的处理( 四 ) _生活百科

public class JacksonUtil {

private static final Logger log = LoggerFactory.getLogger(JacksonUtil.class);

private static final ObjectMapper MAPPER = createObjectMapper();

private JacksonUtil() {}

private static ObjectMapper createObjectMapper() {

ObjectMapper objectMapper = new ObjectMapper();

objectMapper.configure(JsonGenerator.Feature.AUTO_CLOSE_TARGET, false);

objectMapper.disable(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES);

SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");

objectMapper.setDateFormat(df);

return objectMapper;

}

public static ObjectMapper getObjectMapper() {

return MAPPER;

}

第三是启动后修改 MyBatisPlus 的设置, 即下面的 changeObjectMapper() 这个方法, 直接换成了上面工具类中定义的 ObjectMapper, 这样在 MyBatis 读写数据库时的格式也统一了.

@Configuration
@MapperScan(basePackages = {"com.somewhere.commons.impl.mapper"})
public class MybatisPlusConfig {
@Bean
public MybatisPlusInterceptor mybatisPlusInterceptor() {
MybatisPlusInterceptor interceptor = new MybatisPlusInterceptor();
interceptor.addInnerInterceptor(new PaginationInnerInterceptor(DbType.POSTGRE_SQL));
interceptor.addInnerInterceptor(new OptimisticLockerInnerInterceptor());
return interceptor;
}
@PostConstruct
public void changeObjectMapper() {
// This will unify the date format with util methods
JacksonTypeHandler.setObjectMapper(JacksonUtil.getObjectMapper());
}
}
