第一种配置方法：
在实体类中加入格式化属性的注解
public class User implements Serializable{
/**
*
*/
private static final long serialVersionUID = 1L;
private Integer id;
private String username;
private Date birthday;
private Integer age;
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
@JSONField(format="yyyy-MM-dd hh:MM:ss")
public Date getBirthday() {
return birthday;
}
public void setBirthday(Date birthday) {
this.birthday = birthday;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public Integer getAge() {
return age;
}
public void setAge(Integer age) {
this.age = age;
}
2.在启动类中继承类
@SpringBootApplication
public class Demo1Application2 extends WebMvcConfigurerAdapter{
@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);
}
public static void main(String[] args) {
SpringApplication app=new SpringApplication(Demo1Application2.class);
ConfigurableApplicationContext context = app.run( args);
//context.close();
}
}
3.访问页面，请求方法，得到结果
{ "age":11, "birthday":"2018-03-15 10:03:55", "id":1, "username":"dddd" }第二种配置方法：在启动类加入一个bean@SpringBootApplication
public class Demo1Application3 {
@Bean
public HttpMessageConverters fastJsonHttpMessageConverters() {
FastJsonHttpMessageConverter fastConverter=new FastJsonHttpMessageConverter();
FastJsonConfig fastJsonConfig = new FastJsonConfig();
fastJsonConfig.setSerializerFeatures(SerializerFeature.PrettyFormat);
fastConverter.setFastJsonConfig(fastJsonConfig);
HttpMessageConverter<?> converters=fastConverter;
return new HttpMessageConverters(converters);
}
public static void main(String[] args) {
SpringApplication app=new SpringApplication(Demo1Application3.class);
ConfigurableApplicationContext context = app.run( args);
//context.close();
}
}
