Search and Parse Keyword(1)JACKSON for JSON and Jsoup for URL Fetch

Search and Parse Keyword(1)JACKSON for JSON and Jsoup for URL Fetch

1. Using jackson to mapping the JAVA Object and JSON
package com.sillycat.analyzerjava.service.impl;

import java.io.IOException;

import org.codehaus.jackson.JsonGenerationException;

import org.codehaus.jackson.map.JsonMappingException;

import org.codehaus.jackson.map.ObjectMapper;

import org.codehaus.jackson.map.annotate.JsonSerialize.Inclusion;

import com.sillycat.analyzerjava.service.JSONMapperHero;

 

/** * JSON mapper based on jackson *  

* @author sillycat 

*/

public class JSONMapperHeroJacksonImpl<T> implements JSONMapperHero<T> {

 

private ObjectMapper jsonMapper;

/**

* will be called by spring framework

*/

@SuppressWarnings("unused")

private void init() {      

 jsonMapper = new ObjectMapper();      

 jsonMapper.setSerializationInclusion(Inclusion.NON_NULL);

}

 

/**

* mapping the object to JSON String

*/

public String toJSON(T objClass) {

 try {      

   return jsonMapper.writeValueAsString(objClass);

 } catch (JsonGenerationException e) {      

   e.printStackTrace();

 } catch (JsonMappingException e) {      

   e.printStackTrace();

 } catch (IOException e) {      

   e.printStackTrace();

 }

return null;

}

}

It is configured in Spring, so we can adjust it when we want.

2. Jsoup to fetch URL Resource
package com.sillycat.analyzerjava.service.impl;

 

import java.io.IOException;

import org.jsoup.Jsoup;

import com.sillycat.analyzerjava.service.ResourceFetchHero;

import com.sillycat.analyzerjava.service.base.BaseHero;

 

public class ResourceFetchHeroJsoupImpl extends BaseHero implements ResourceFetchHero{

 

public String getTitlefromURL(String url) {

  String result = null;

  try {

    log.debug("====================================");

    log.debug("searching title for url:" + url);

    result = Jsoup.connect(url).get().title();

    log.debug("title:" + result);

    log.debug("====================================");

  } catch (IOException e) {

    log.error("Exception:" + e);

  }

  returnresult;

}

 

}

Dependencies in pom.xml
<!-- jsoup HTML parser library @ http://jsoup.org/ -->

<dependency>  

  <groupId>org.jsoup</groupId>  

  <artifactId>jsoup</artifactId>
