Spring Boot BigDecimal 返回时转为 String

Spring Boot About 577 words

需求

金额字段如果以数字类型返回给前端时,JavaScript可能会丢失精度,需在服务端转为String保证精度不丢失。

代码

主要是simpleModule.addSerializer添加BigDecimal转为String的处理方式ToStringSerializer

@Configuration
public class ObjectMapperConfig {

    @Bean
    public ObjectMapper objectMapper(Jackson2ObjectMapperBuilder builder) {
        ObjectMapper objectMapper = builder.createXmlMapper(false).build();
        SimpleModule simpleModule = new SimpleModule();
        simpleModule.addSerializer(BigDecimal.class, ToStringSerializer.instance);
        objectMapper.registerModule(simpleModule);
        return objectMapper;
    }

}
