1、添加fastjson配置
<dependency> <groupId>com.alibaba</groupId> <artifactId>fastjson</artifactId> <version>1.2.15</version> </dependency>
2、重写configureMessageConverters
@Override public void configureMessageConverters(List<HttpMessageConverter<?>> converters) { super.configureMessageConverters(converters); FastJsonHttpMessageConverter fastConverter=new FastJsonHttpMessageConverter(); FastJsonConfig fastJsonConfig=new FastJsonConfig(); fastJsonConfig.setSerializerFeatures(SerializerFeature.PrettyFormat); fastConverter.setFastJsonConfig(fastJsonConfig); converters.add(fastConverter); }
3、运行http://127.0.0.1:8080/getstudent
浏览器输出有乱码
4、修改Controller
@RequestMapping(value = "/getstudent", produces = "application/json; charset=utf-8") public Student getStudent() { Student student=new Student(); student.id=1; student.name="小明"; return student; }
5、再次运行，正常，并且可以看到fastjson已经自动格式化了输出内容
6、常用注解
@JSONField(serialize = false) //不参与格式化
@JSONField(serialzeFeatures=SerializerFeature.WriteMapNullValue) //输出NULL
7、也可以代码中直接使用
System.out.println(JSON.toJSONStringWithDateFormat(ao, "yyyy-MM-dd HH:mm:ss.SSS"));
总结：本篇其实和SpringBoot关系不大，传统SpringMVC+Hibernate也可以用。
