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); 

									} 

									}
