加入maven 依赖
<dependency> <groupId>com.alibaba</groupId> <artifactId>fastjson</artifactId> <version>1.2.45</version> </dependency>
创建HttpMessageConverters ，这里是无XML方式创建
import org.springframework.boot.autoconfigure.web.HttpMessageConverters;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import com.alibaba.fastjson.serializer.SerializerFeature;
import com.alibaba.fastjson.support.config.FastJsonConfig;
import com.alibaba.fastjson.support.spring.FastJsonHttpMessageConverter;
@Configuration
public class BeanConfig {
@Bean
public HttpMessageConverters fastJsonHttpMessageConverters() {
FastJsonHttpMessageConverter converter = new FastJsonHttpMessageConverter();
FastJsonConfig config = new FastJsonConfig();
config.setSerializerFeatures(SerializerFeature.PrettyFormat);
config.setSerializerFeatures();
converter.setFastJsonConfig(config);
converter.setDefaultCharset(Charset.forName("UTF-8")); // 设置编码
return new HttpMessageConverters(converter);
}
}如果传输Bean 对象 可以在字段上使用 @JSONField 注解来制定返回json 对象
@JSONField(format="yyyy-MM-dd HH:mm:ss")
private Date createTime;
@JSONField(serialize=false)
