spring boot使用fastjson

1、添加maven依赖<dependency> <groupId>org.codehaus.jackson</groupId> <artifactId>jackson-mapper-asl</artifactId> <version>1.9.13</version></dependency>

2、在启动类中注入bean@EnableDiscoveryClient@SpringBootApplication@MapperScan("com.shianyun.cdmproject.dao")public class AIprojectApplication { @Bean public HttpMessageConverters fastJsonHttpMessageConverters() { // 1.定义一个converters转换消息的对象 FastJsonHttpMessageConverter fastConverter = new FastJsonHttpMessageConverter(); // 2.添加fastjson的配置信息，比如: 是否需要格式化返回的json数据 FastJsonConfig fastJsonConfig = new FastJsonConfig(); fastJsonConfig.setSerializerFeatures(SerializerFeature.PrettyFormat); // 3.在converter中添加配置信息 fastConverter.setFastJsonConfig(fastJsonConfig); //日期格式化 fastJsonConfig.setDateFormat("yyyy-MM-dd HH:mm:ss"); // 4.将converter赋值给HttpMessageConverter HttpMessageConverter<?> converter = fastConverter; // 5.返回HttpMessageConverters对象 return new HttpMessageConverters(converter); } public static void main(String[] args) { SpringApplication.run(AIprojectApplication.class, args); }}

3、测试查询接口返回：
