最近在研究springboot實現FastJson解析json數據的方法，那么今天也算個學習筆記吧！
添加jar包：
|
1

5
|
<dependency> <groupId>com.alibaba</groupId> <artifactId>fastjson</artifactId> <version>1.2.15</version> </dependency> |
兩種方式啟動加載類：
第一種繼承WebMvcConfigurerAdapter，重寫configureMessageConverters方法：

import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; 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; @SpringBootApplicationpublic class App extends WebMvcConfigurerAdapter{ public static void main(String[] args) { SpringApplication.run(App.class, args); } @Overridepublic void configureMessageConverters( List<HttpMessageConverter<?>> converters) { // TODO Auto-generated method stub super.configureMessageConverters(converters); FastJsonHttpMessageConverter fastConverter = new FastJsonHttpMessageConverter(); FastJsonConfig fastJsonConfig = new FastJsonConfig(); fastJsonConfig.setSerializerFeatures( SerializerFeature.PrettyFormat ); fastConverter.setFastJsonConfig(fastJsonConfig); converters.add(fastConverter); } } |
第二種方式bean注入HttpMessageConverters：

import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.boot.autoconfigure.web.HttpMessageConverters; import org.springframework.context.annotation.Bean; import org.springframework.http.converter.HttpMessageConverter; import com.alibaba.fastjson.serializer.SerializerFeature; import com.alibaba.fastjson.support.config.FastJsonConfig; import com.alibaba.fastjson.support.spring.FastJsonHttpMessageConverter; @SpringBootApplicationpublic class AppTwo{ public static void main(String[] args) { SpringApplication.run(AppTwo.class, args); } @Beanpublic HttpMessageConverters fastJsonHttpMessageConverters() { FastJsonHttpMessageConverter fastConverter = new FastJsonHttpMessageConverter(); FastJsonConfig fastJsonConfig = new FastJsonConfig(); fastJsonConfig.setSerializerFeatures(SerializerFeature.PrettyFormat); fastConverter.setFastJsonConfig(fastJsonConfig); HttpMessageConverter<?> converter = fastConverter; return new HttpMessageConverters(converter); } } |
最后屬性前加@JSONField：
|
1
2
|
@JSONField(serialize=false) private Long id; |
返回前端就會沒有id這個屬性值
以上就是本文的全部內容，希望對大家的學習有所幫助，也希望大家多多支持服務器之家。
