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
