添加jar包:
com.alibaba fastjson 1.2.15
两种方式启动加载类:
第一种继承WebMvcConfigurerAdapter,重写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; @SpringBootApplication public class App extends WebMvcConfigurerAdapter{ public static void main(String[] args) { SpringApplication.run(App.class, args); } @Override public void configureMessageConverters( List> 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); } }
第二种方式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; @SpringBootApplication public class AppTwo{ public static void main(String[] args) { SpringApplication.run(AppTwo.class, args); } @Bean public HttpMessageConverters fastJsonHttpMessageConverters() { FastJsonHttpMessageConverter fastConverter = new FastJsonHttpMessageConverter(); FastJsonConfig fastJsonConfig = new FastJsonConfig(); fastJsonConfig.setSerializerFeatures(SerializerFeature.PrettyFormat); fastConverter.setFastJsonConfig(fastJsonConfig); HttpMessageConverter<?> converter = fastConverter; return new HttpMessageConverters(converter); } }
最后属性前加@JSONField:
@JSONField(serialize=false) private Long id;
返回前端就会没有id这个属性值
