SpringBoot-------阿里fastjson配置

 
            org.springframework.boot
            spring-boot-starter-web
            
            
                
                    com.fasterxml.jackson.core
                    jackson-bom
                
            
        

 
        
            com.alibaba
            fastjson
            1.2.75
        

package test11.fastjson;


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.Bean;
import org.springframework.context.annotation.Configuration;

import java.nio.charset.StandardCharsets;

@Configuration
public class MyFastJsonConfig {
    @Bean
    FastJsonHttpMessageConverter fastJsonHttpMessageConverter(){
       FastJsonHttpMessageConverter converter=new FastJsonHttpMessageConverter();
        FastJsonConfig config=new FastJsonConfig();
        config.setDateFormat("yyy-MM-dd");
        config.setCharset(StandardCharsets.UTF_8);
        config.setSerializerFeatures(
                SerializerFeature.WriteClassName,
                SerializerFeature.WriteMapNullValue,
                SerializerFeature.PrettyFormat,
                SerializerFeature.WriteNullListAsEmpty,
                SerializerFeature.WriteNullStringAsEmpty
        );
        converter.setFastJsonConfig(config);
        return converter;
    }
}

还可以重新configureMessageConverters进行配置

package test11.fastjson;

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.WebMvcConfigurer;

import java.nio.charset.StandardCharsets;
import java.util.List;

@Configuration
public class MyWebMvcConfig implements WebMvcConfigurer {
    @Override
    public void configureMessageConverters(List> converters) {
        FastJsonHttpMessageConverter converter=new FastJsonHttpMessageConverter();
        FastJsonConfig config=new FastJsonConfig();
        config.setDateFormat("yyy-MM-dd");
        config.setCharset(StandardCharsets.UTF_8);
        config.setSerializerFeatures(
                SerializerFeature.WriteClassName,
                SerializerFeature.WriteMapNullValue,
                SerializerFeature.PrettyFormat,
                SerializerFeature.WriteNullListAsEmpty,
                SerializerFeature.WriteNullStringAsEmpty
        );
        converter.setFastJsonConfig(config);
        converters.add(converter);
    }
}

MyFastjsonConfig配置完成后,需要配置响应编码,否则返回的JSON中文会出现乱码

server.servlet.encoding.force-response=true
