2023-08-14 18:53:10

springBoot自带的json用着不太习惯，已习惯了fastJSON，下面介绍下fastjson的配置

1. pom引入

　　　　<dependency>

            <groupId>com.alibaba</groupId>

            <artifactId>fastjson</artifactId>

            <version>1.2.15</version>

        </dependency>

2.配置时间格式及编码，反正中文乱码

package com.xiao.config;

import java.util.ArrayList;

import java.util.List;

import org.springframework.context.annotation.Configuration;

import org.springframework.http.MediaType;

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;

@Configuration

public class FastJSONConfig extends WebMvcConfigurerAdapter {

    @Override

    public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {

        FastJsonHttpMessageConverter fastConverter = new FastJsonHttpMessageConverter();

        FastJsonConfig fastJsonConfig = new FastJsonConfig();

        fastJsonConfig.setSerializerFeatures(SerializerFeature.PrettyFormat);

        fastJsonConfig.setDateFormat("yyyy-MM-dd HH:mm:ss");

        // 处理中文乱码问题

        List<MediaType> fastMediaTypes = new ArrayList<>();

        fastMediaTypes.add(MediaType.APPLICATION_JSON_UTF8);

        fastConverter.setSupportedMediaTypes(fastMediaTypes);

        fastConverter.setFastJsonConfig(fastJsonConfig);

        converters.add(fastConverter);

    }

}

3.代码测试

@RequestMapping(value = "/json/test")

    public Result jsonTest(@Valid User user) {

        System.out.println(JSON.toJSONString(user));

        return new Result(user);

    }

4.结果
