springboot实现FastJson解析json数据的方法

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
