fastjson

方法一:在启动类中添加@Bean

@Bean
    public HttpMessageConverters fastJsonHttpMessageConverters(){
        FastJsonHttpMessageConverter fastConConverter=new FastJsonHttpMessageConverter();
        FastJsonConfig fastJsonConfig=new FastJsonConfig();
        fastJsonConfig.setSerializerFeatures(
                SerializerFeature.PrettyFormat
        );
        fastConConverter.setFastJsonConfig(fastJsonConfig);
        HttpMessageConverter<?> converter=fastConConverter;
        return new HttpMessageConverters(converter);
    }

方法二:启动类中继承WebMvcConfigurerAdapter ，复写configureMessageConverters

public class TestApplication extends WebMvcConfigurerAdapter {

    @Override
    public void configureMessageConverters(List<HttpMessageConverter<?>> converters){
        super.configureMessageConverters(converters);
        FastJsonHttpMessageConverter fastConverter=new FastJsonHttpMessageConverter();
        FastJsonConfig fastJsonConfig=new FastJsonConfig();
        fastJsonConfig.setSerializerFeatures(
                SerializerFeature.PrettyFormat
        );
        fastConverter.setFastJsonConfig(fastJsonConfig);
        converters.add(fastConverter);

    }

pom.xml中添加配置：

        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>fastjson</artifactId>
            <version>1.2.41</version
        </dependency>

实体类中

   /**
     * 日期格式化
     */
    @JSONField(format="yyyy-MM-dd HH:mm")
    private Date creatTime;

    /**
     * remark内容不显示
     */
    @JSONField(serialize = false)
    private String remark;
