//首先导入jackson-annotations-2.2.1.jar,jackson-core-2.2.1.jar,jackson-databind-2.2.1.jar
//1.创建ObjectMapper对象
ObjectMapper mapper=new ObjectMapper();
//2.调用mapper的writeValueAsString将对象转为json字符串
Customer customer=new Customer("zzq","001");
String jsonStr=mapper.writeValueAsString(customer);
System.out.println(jsonStr);
//3.jackson使用get方法来定位对象的属性
//4.通过添加注解可以不输出某一属性@JsonIgnore
//5.将集合转化为json
List<Customer> customers=Arrays.asList(customer,new Customer("BCD","002"));
jsonStr=mapper.writeValueAsString(customers);
System.out.println("--"+jsonStr);
}
}
jackson 将对象,集合转化为json
