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
