SpringBoot整合 fastjson

fastjson属于阿里，号称最快的解析方式

• pom

要排除掉自带的 json解析方式

• config

还需要再new FastJsonConfig()，才能用 setDateFormat()

package com.thciwei.demo.config;

import com.alibaba.fastjson.support.config.FastJsonConfig;
import com.alibaba.fastjson.support.spring.FastJsonHttpMessageConverter;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import java.text.SimpleDateFormat;

@Configuration
public class BootConfig {

    @Bean
    FastJsonHttpMessageConverter fastJsonHttpMessageConverter() {
        FastJsonHttpMessageConverter converter = new FastJsonHttpMessageConverter();
        FastJsonConfig config = new FastJsonConfig();
        config.setDateFormat("yyyy-MM-dd");
        converter.setFastJsonConfig(config);
        return converter;

    }

}
