SpringBoot 使用fastjson

spring boot默认使用的json解析框架是jackson，替换为fastjson有两种方式

1.继承WebMvcConfigurerAdapter

@SpringBootApplication
public class App extends WebMvcConfigurerAdapter{
    @Override
    public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {
        super.configureMessageConverters(converters);
    
        FastJsonHttpMessageConverter fastConverter=new FastJsonHttpMessageConverter();    
        FastJsonConfig fastJsonConfig=new FastJsonConfig();
        fastJsonConfig.setSerializerFeatures(SerializerFeature.PrettyFormat);
        fastConverter.setFastJsonConfig(fastJsonConfig);
        converters.add(fastConverter);
    }

    public static void main(String[] args) {
        SpringApplication.run(App.class,args);
    }
}

2.使用@Bean注入方式

@Configuration
public class WebMvcConfig{

    @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);
    }
}
