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：
<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;
@SpringBootApplication
public class App extends WebMvcConfigurerAdapter{
public static void main(String[] args) {
SpringApplication.run(App.class, args);
}
@Override
public 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;
@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);
}
}
最后屬性前加@JSONField：
@JSONField(serialize=false) private Long id;
返回前端就會沒有id這個屬性值
