Using Jackson to parse the JSON demo sample

First you need to download 3 packages, on GitHub Fasterxml, these three core modules are:Streaming ("jackson-core") defines low-level streaming API, and includes json-specific implementations Annotations ("jackson-annotations") contains standard Jackson AnnotationsDatabind ("jackson-databind") implements Data-binding (and object serialization) support on streaming package;It depends both on streaming and annotations packages.
JSON file:

<span style= "FONT-FAMILY:SIMHEI;FONT-SIZE:18PX;" >{     "name": "Vonzhou",     "age": 123,     "Isman":true}</span>

Pojo class:

<span style= "FONT-FAMILY:SIMHEI;FONT-SIZE:18PX;" >package Jackson.test;import Java.util.hashmap;import Java.util.map;import Com.fasterxml.jackson.annotation.jsonproperty;public class Examplepojo {@JsonProperty ("name") Private String N           Ame           @JsonProperty ("age") private Integer age;           @JsonProperty ("Isman") private Boolean Isman;           Private map<string,object> additionalproperties = new hashmap<string, object> ();     @JsonProperty ("name") public String GetName () {return name;     } @JsonProperty ("name") public void SetName (String name) {this. name = name;     } @JsonProperty ("Age") public Integer Getage () {return age;     } @JsonProperty ("Age") public void Setage (Integer age) {this.     } @JsonProperty ("Isman") public Boolean Getisman () {return isman; } @JsonProperty ("Isman")      public void Setisman (Boolean isman) {this. Isman = Isman;     } public map<string, Object> getadditionalproperties () {return additionalproperties; public void Setadditionalproperties (String name, Object obj) {this. additionalproperties.put (name, obj)     ; } @Override Public String toString () {return "examplepojo{\n" + "Name: '"                      + name + "', \ n" + "Age:" + age + ", \ n" + "Isman:" + Isman + ", \ n" +     "Additionalproperties:" + additionalproperties + "\ n}"; }}</span>

the class that parses the JSON file:

<span style= "FONT-FAMILY:SIMHEI;FONT-SIZE:18PX;" >package Jackson.test;import Java.io.file;import Java.io.ioexception;import Com.fasterxml.jackson.core.jsonparseexception;import Com.fasterxml.jackson.databind.jsonmappingexception;import Com.fasterxml.jackson.databind.objectmapper;public class Driver {public static void main (string[] args) {Ob          Jectmapper mapper = new Objectmapper ();                                                                  try {Examplepojo bean = Mapper.readvalue (new File ("Test.json"),               Examplepojo.class);               System.out.println ("Name:" + bean.getname ());               System.out.println ("Age:" + bean.getage ());               System.out.println ("Isman:" + Bean.getisman ());               System.out.println ("===================");          System.out.println (Bean.tostring ());          } catch (Jsonparseexception e) {e.printstacktrace ();         }catch (Jsonmappingexception e) {      E.printstacktrace ();          }catch (IOException e) {e.printstacktrace (); }}}</span>
