如何在Spring Boot 1.4中自定义Jackson

如何在Spring Boot 1.4中自定义Jackson

为了自定义

ObjectMapper

Spring Boot已经预先配置的Jackson ，我能够做到这一点（这里的示例是添加一个自定义解串器）。

配置类：

@SpringBootConfigurationpublic class Application {    @Autowired    private BigDecimalDeserializer bigDecimalDeserializer;    ...    @Bean    public Jackson2ObjectMapperBuilderCustomizer addCustomBigDecimalDeserialization() {        return new Jackson2ObjectMapperBuilderCustomizer() { @Override public void customize(Jackson2ObjectMapperBuilder jacksonObjectMapperBuilder) {     jacksonObjectMapperBuilder.deserializerByType(BigDecimal.class, bigDecimalDeserializer); }        };    }    ...}

还有我的自定义反序列化器，以显示Spring如何拾取它：

@Componentpublic class BigDecimalDeserializer extends StdDeserializer<BigDecimal> {    public BigDecimalDeserializer() {        super(BigDecimal.class);    }    @Override    public BigDecimal deserialize(JsonParser p, DeserializationContext ctxt) throws IOException {        ...    }    ...}
