controller返回json数据，过滤属性

User user = new User();
user.setId(1L);
user.setAge(12);
user.setName("zhangsan");
user.setBirthDate(new Date());
String jsonString1 = JSON.toJSONString(user);
System.out.println(jsonString1);

SimplePropertyPreFilter filter = new SimplePropertyPreFilter(User.class, "na", "address");
String jsonString2 = JSON.toJSONString(user, filter);
System.out.println(jsonString2);

输出结果

{"id":1,"na":"zhangsan","address":null,"birthDate":"2018-01-08  14:24:28"}
{"na":"zhangsan","address":null}

上面是在代码中体现的过滤数据，下面直接使用注解

1.@JSONField(serialize = false)

2.@JsonIgnore
