fastjson是阿里出的,尽管近年fasjson爆出过几次严重漏洞,但是平心而论,fastjson的性能的确很有优势,尤其是大数据量时的性能优势,所以fastjson依然是我们的首选;spring boot默认的json解析器是Jackson,替换为fastjson很有必要;
<!-- fastjson --> <dependency> <groupId>com.alibaba</groupId> <artifactId>fastjson</artifactId> <version>1.2.62</version> </dependency>
注意:Springboot2.0以后,WebMvcConfigurerAdapter 过时了, 以前1版本继承WebMvcConfigurerAdapter 来实现的方法不推荐了。下面介绍两种配置方式,还有一种实现WebMvcConfigurationSupport的方式就不介绍了,道路千万条,选一条就足够了:
package com.anson.config; import com.alibaba.fastjson.serializer.SerializerFeature; import com.alibaba.fastjson.support.config.FastJsonConfig; import com.alibaba.fastjson.support.spring.FastJsonHttpMessageConverter; import org.springframework.boot.autoconfigure.http.HttpMessageConverters; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.http.MediaType; import org.springframework.http.converter.HttpMessageConverter; import java.nio.charset.Charset; import java.util.ArrayList; import java.util.List; @Configuration public class WebConfig { /** * @Author anson * @Description 配置消息转换器 * @Date: 2019-12-8 11:23:33 * @version: 1.0 * new HttpMessageConverters(true, converters); * 一定要设为true才能替换否则不会替换 * @return 返回一个消息转换的bean */ @Bean public HttpMessageConverters fastJsonMessageConverters() { List<HttpMessageConverter<?>> converters = new ArrayList<>(); //需要定义一个convert转换消息的对象; FastJsonHttpMessageConverter fastConverter = new FastJsonHttpMessageConverter(); //添加fastJson的配置信息; FastJsonConfig fastJsonConfig = new FastJsonConfig(); fastJsonConfig.setSerializerFeatures(SerializerFeature.PrettyFormat); //全局时间配置 fastJsonConfig.setDateFormat("yyyy-MM-dd HH:mm:ss"); fastJsonConfig.setCharset(Charset.forName("UTF-8")); //处理中文乱码问题 List<MediaType> fastMediaTypes = new ArrayList<>(); fastMediaTypes.add(MediaType.APPLICATION_JSON_UTF8); //在convert中添加配置信息. fastConverter.setSupportedMediaTypes(fastMediaTypes); fastConverter.setFastJsonConfig(fastJsonConfig); converters.add(0, fastConverter); return new HttpMessageConverters(converters); } }
方式二、实现WebMvcConfigurer
@Configuration public class WebConfigure implements WebMvcConfigurer
{ /** * 配置消息转换器 * @param converters */ @Override public void configureMessageConverters(List<HttpMessageConverter<?>> converters) { //需要定义一个convert转换消息的对象; FastJsonHttpMessageConverter fastConverter = new FastJsonHttpMessageConverter(); //添加fastJson的配置信息; FastJsonConfig fastJsonConfig = new FastJsonConfig(); fastJsonConfig.setSerializerFeatures(SerializerFeature.PrettyFormat); //全局时间配置 fastJsonConfig.setDateFormat("yyyy-MM-dd HH:mm:ss"); fastJsonConfig.setCharset(Charset.forName("UTF-8")); //处理中文乱码问题 List<MediaType> fastMediaTypes = new ArrayList<>(); fastMediaTypes.add(MediaType.APPLICATION_JSON_UTF8); //在convert中添加配置信息. fastConverter.setSupportedMediaTypes(fastMediaTypes); fastConverter.setFastJsonConfig(fastJsonConfig); converters.add(0,fastConverter); } }
spring boot2 修改默认json解析器Jackson为fastjson
