2. TEST 코드
import java.util.logging.Logger;
import org.json.simple.JSONObject;
import org.json.simple.parser.JSONParser;
import org.json.simple.parser.ParseException;
//import net.minidev.json.JSONObject;
//import net.minidev.json.parser.JSONParser;
//import net.minidev.json.parser.ParseException;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
public class test {
Logger logger = Logger.getLogger("xxx");
@RequestMapping("/test")
public String tests() {
//JSON => String
JSONObject jsonObj = new JSONObject();
jsonObj.put("value1", 1111);
jsonObj.put("value2", 2222);
jsonObj.put("value3", 3333);
logger.info( "Info : "+jsonObj.toString());
//String => JSON
String jsonString = jsonObj.toString();
JSONParser parser = new JSONParser();
try {
Object obj = parser.parse(jsonString);
jsonObj = (JSONObject) obj;
logger.info( "Info : "+jsonObj.get("value1"));
logger.info( "Info : "+jsonObj.get("value2"));
logger.info( "Info : "+jsonObj.get("value3"));
}catch ( ParseException e ){
}
return "test";
}
}
==============결과=====================================
정보: Info : {"value3":3333,"value1":1111,"value2":2222}
정보: Info : 1111
정보: Info : 2222
정보: Info : 3333
=======================================================
3. String JSONObject 좀더 간단하게
<dependency>
<groupId>org.json</groupId>
<artifactId>json</artifactId>
<version>20140107</version>
</dependency>
import java.util.logging.Logger;
import org.json.JSONObject;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
public class test {
Logger logger = Logger.getLogger("xxx");
@RequestMapping("/test")
public String tests() {
//String => JSON
String jsonString = "{\"value3\":3333,\"value1\":1111,\"value2\":2222}";
JSONObject jsonObj = new JSONObject(jsonString);
logger.info( "Info : "+jsonObj.get("value1"));
logger.info( "Info : "+jsonObj.get("value2"));
logger.info( "Info : "+jsonObj.get("value3"));
return "test";
}
}
