最近在研究springboot实现FastJson解析json数据的方法,那么今天也算个学习笔记吧!
添加jar包:
1
2
3
4
5
|
< dependency > < groupId >com.alibaba</ groupId > < artifactId >fastjson</ artifactId > < version >1.2.15</ version > </ dependency > |
两种方式启动加载类:
第一种继承WebMvcConfigurerAdapter,重写configureMessageConverters方法:

import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.http.converter.HttpMessageConverter; import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter; import com.alibaba.fastjson.serializer.SerializerFeature; import com.alibaba.fastjson.support.config.FastJsonConfig; import com.alibaba.fastjson.support.spring.FastJsonHttpMessageConverter; @SpringBootApplication public class App extends WebMvcConfigurerAdapter{ public static void main(String[] args) { SpringApplication.run(App. class , args); } @Override public void configureMessageConverters( List<HttpMessageConverter<?>> converters) { // TODO Auto-generated method stub super .configureMessageConverters(converters); FastJsonHttpMessageConverter fastConverter = new FastJsonHttpMessageConverter(); FastJsonConfig fastJsonConfig = new FastJsonConfig(); fastJsonConfig.setSerializerFeatures( SerializerFeature.PrettyFormat ); fastConverter.setFastJsonConfig(fastJsonConfig); converters.add(fastConverter); } } |
第二种方式bean注入HttpMessageConverters:

import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.boot.autoconfigure.web.HttpMessageConverters; import org.springframework.context.annotation.Bean; import org.springframework.http.converter.HttpMessageConverter; import com.alibaba.fastjson.serializer.SerializerFeature; import com.alibaba.fastjson.support.config.FastJsonConfig; import com.alibaba.fastjson.support.spring.FastJsonHttpMessageConverter; @SpringBootApplication public class AppTwo{ public static void main(String[] args) { SpringApplication.run(AppTwo. class , args); } @Bean public HttpMessageConverters fastJsonHttpMessageConverters() { FastJsonHttpMessageConverter fastConverter = new FastJsonHttpMessageConverter(); FastJsonConfig fastJsonConfig = new FastJsonConfig(); fastJsonConfig.setSerializerFeatures(SerializerFeature.PrettyFormat); fastConverter.setFastJsonConfig(fastJsonConfig); HttpMessageConverter<?> converter = fastConverter; return new HttpMessageConverters(converter); } } |
最后属性前加@JSONField:
1
2
|
@JSONField (serialize= false ) private Long id; |
返回前端就会没有id这个属性值
以上就是本文的全部内容,希望对大家的学习有所帮助,也希望大家多多支持服务器之家。
