How to ignore attribute when mapping to json from a text file to a Java object using Jackson? -

this question has answer here:

• jackson json deserialization root element 1 answer

i have text file 'input.txt' contains text

{   "product" : {     "name" : "pro-1",     "category" : "a"   } } 

and class

public class  product {     @jsonproperty("name")     public string name;     @jsonproperty("category")     public string category     ...     ... } 

i using jackson

product p = mapper.readvalue(new file("input.txt"), product.class); 

my class has no attribute named "product" , result exception occurs when mapping json text product object. so, proper way ignore "product" attribute when mapping product object text file?

try this.

public class outerclass{     @jsonproperty("product")     public product product; }  outerclass outerobject = mapper.readvalue(new file("input.txt"), outerclass.class); 

then can use outerobject.product
