springboot实现FastJson解析json数据的方法

发布日期： 2026-01-12 阅读量： 作者： 用户投稿

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
