解决SpringBoot2中前台Long型数据精度丢失问题

想要解决long类型丢失问题，必要将long类型转换为String类型再传输，一共有三种解决方案

方案一：注解方式：实体类中增加注解

/** 主键ID */
@Id
@GeneratedValue(generator = "ID")
@GenericGenerator(name = "ID", strategy = "assigned")
@Column(insertable = false, name = "ID", nullable = false,length = 64)
@JsonSerialize(using = ToStringSerializer.class)//解决long精度丢失问题
private Long id;

方案二：自定义ObjectMapper （推荐）：启动类中增加配置

@SpringBootApplication
@EnableTransactionManagement
public class Application {

	/**
	 * 解决Jackson导致Long型数据精度丢失问题
	 * @return
	 */
	@Bean("jackson2ObjectMapperBuilderCustomizer")
	public Jackson2ObjectMapperBuilderCustomizer jackson2ObjectMapperBuilderCustomizer() {
		Jackson2ObjectMapperBuilderCustomizer customizer = new Jackson2ObjectMapperBuilderCustomizer() {
			@Override
			public void customize(Jackson2ObjectMapperBuilder jacksonObjectMapperBuilder) {
				jacksonObjectMap
