You see, I have the following json:
"signaturesType":[
"SIMPLE"
],
"docs":[
"contrato"
]
How can I get the values inside the tags signaturesType and docs. What is strange about me is that it does not come as the classic json, which would be property: value, that is why I doubt how I can obtain the values stored there. Greetings and thanks.
You can use Google Gson , but first you should modify your json since you need the {} to indicate that what is inside is an object, you can check all that here JSON org , the brackets [] in JSON represent an array and can be mapped to a Collection as a List or a Array . . p>
import java.util.List;
import com.google.gson.Gson;
public class Test {
public static void main(String... args) throws Exception {
String json = "{'signaturesType':["+
"'SIMPLE'"+
"],"+
"'docs':["+
"'contrato'"+
"]}";
// Aquí se hace la conversión
Data data = new Gson().fromJson(json, Data.class);
// Se muestra así
System.out.println(data.getSignaturesType().get(0));
// Se muestra así
System.out.println(data.getDocs().get(0));
}
}
class Data {
private List<String> signaturesType;
private List<String> docs;
/**
* @return the signaturesType
*/
public List<String> getSignaturesType() {
return signaturesType;
}
/**
* @param signaturesType the signaturesType to set
*/
public void setSignaturesType(List<String> signaturesType) {
this.signaturesType = signaturesType;
}
/**
* @return the docs
*/
public List<String> getDocs() {
return docs;
}
/**
* @param docs the docs to set
*/
public void setDocs(List<String> docs) {
this.docs = docs;
}
}
This would be the result:
SIMPLE
contract
To be well formed, the json object should be:
{"signaturesType":["SIMPLE"],"docs":["contrato"]}
What is equivalent to a java class
public class Xxx{
public List<String> signaturesType;
public List<String> docs;
}
Using the gson library you can convert the String into an instance of a java class.
String jsonString = "{\"signaturesType\":[\"SIMPLE\"],\"docs\":[\"contrato\"]}";
Xxx xxx = new Gson().fromJson(jsonString, Xxx.class);
