SpringBoot 使用fastjson初识

1.  pom文件里引入fastjson的jar

<dependency>   <groupId>com.alibaba</groupId>   <artifactId>fastjson</artifactId>   <version>1.2.35</version></dependency>

2. 在主函数中注入Bean

@Beanpublic HttpMessageConverters fastJsonHttpMessageConverters(){   FastJsonHttpMessageConverter fastConverter = new FastJsonHttpMessageConverter();   HttpMessageConverter<?> converter = fastConverter;   return new HttpMessageConverters(converter);}

3. 测试结果

jackson:  {"id":1,"nickname":"laoli","mobile":"111","headimg":null,"verifyflag":null,"enableflag":null}

fastjson:  {"mobile":"111","nickname":"laoli","id":1}

区别：jackson不会转化为null的字段，效率低于fastjson
