SpringBoot中，使用 fastjson代替jackson

• 方案一

package org.zln.springbootfastjson.web.config;

import com.alibaba.fastjson.serializer.SerializerFeature;
import com.alibaba.fastjson.support.config.FastJsonConfig;
import com.alibaba.fastjson.support.spring.FastJsonHttpMessageConverter;
import org.springframework.context.annotation.Configuration;
import org.springframework.http.converter.HttpMessageConverter;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;

import java.util.List;

/** * @Author sherry * @Description * @Date Create in 2018/4/26 * @Modified By: */
@Configuration
public class WebConfig extends WebMvcConfigurerAdapter {
    @Override
    public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {
        super.configureMessageConverters(converters);


// 消息轉換對象
        FastJsonHttpMessageConverter fastJsonHttpMessageConverter = new FastJsonHttpMessageConverter();
// 配置
        FastJsonConfig fastJsonConfig = new FastJsonConfig();
// 格式化輸出
        fastJsonConfig.setSerializerFeatures(SerializerFeature.PrettyFormat);
        fastJsonHttpMessageConverter.setFastJsonConfig(fastJsonConfig);
// 添加消息轉化配置
        converters.add(fastJsonHttpMessageConverter);
    }
}

可是不推薦這麼作

一、fastjson的速度沒有比jackson快不少
二、jackson功能更增強大

• 方案二

@Bean
    public HttpMessageConverters fastJsonHttpMessageConverters(){
        FastJsonHttpMessageConverter fastJsonHttpMessageConverter = new FastJsonHttpMessageConverter();
        FastJsonConfig fastJsonConfig = new FastJsonConfig();
        fastJsonConfig.setSerializerFeatures(SerializerFeature.PrettyFormat);
        fastJsonHttpMessageConverter.setFastJsonConfig(fastJsonConfig);
        
        HttpMessageConverter<?> converter = fastJsonHttpMessageConverter;
        return new HttpMessageConverters(converter);
        
        
    }
