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：

<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：

@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。
