To use jackson you need to create a model class:
[
{
"serviceNo":"SR0000000001",
"serDate":"17",
"serMonth":"DEC",
"serYear":"2015",
"serTime":"02.30 AM",
"serApartmentName":"Galaxy Apartments"
},
{
"serviceNo":"SR0000000002",
"serDate":"19",
"serMonth":"JUN",
"serYear":"2016",
"serTime":"03.30 AM",
"serApartmentName":"The Great Apartments"
}
]
For the above the json the model class would be:
public class SomeClass {
private String serviceNo;
private String serDate;
private String serMonth;
private String serYear;
private String serTime;
private String serApartmentName;
@JsonProperty("serviceNo") //to bind it to serviceNo attribute of the json string
public String getServiceNo() {
return serviceNo;
}
public void setServiceNo(String sNo) { //@JsonProperty need not be specified again
serviceNo = sNo;
}
//create getter setters like above for all the properties.
//if you want to avoid a key-value from getting parsed use @JsonIgnore annotation
}
Now whenever you have the above json as string stored in a variable say jsonString use the following code to parse it:
ObjectMapper mapper = new ObjectMapper(); // create once, reuse
ArrayList<SomeClass> results = mapper.readValue(jsonString,
new TypeReference<ArrayList<ResultValue>>() { } );
results should now contain two SomeClass objects having the above json parsed as respective objects.
PS: Its been a long time since I have used Jackson for parsing so this code might need some improvements.
