spring mvc - Migrate custom ObjectMapper from Jackson to Jackson2 -


i have following custom objectmapper jackson 1.9.13.

package de.outsourcing.rest.json;  import com.liferay.portal.model.basemodel; import com.liferay.portal.service.servicecontext; import com.liferay.portlet.expando.model.expandobridge;  import org.codehaus.jackson.jsonfactory; import org.codehaus.jackson.annotate.jsonignore; import org.codehaus.jackson.map.deserializationconfig; import org.codehaus.jackson.map.deserializerprovider; import org.codehaus.jackson.map.objectmapper; import org.codehaus.jackson.map.serializationconfig; import org.codehaus.jackson.map.serializerprovider; import org.codehaus.jackson.type.javatype;  /***************************************************************************  * <b>description:</b> objectmapper add mixin annotations  * make service builder entities valid jackson   * deserialization  * <b>created:</b>20 feb 2014 17:48:09  @author vitor silva   **************************************************************************/ public class liferayobjectmapper extends objectmapper {  public liferayobjectmapper() {     super(); }  public liferayobjectmapper(jsonfactory jf, serializerprovider sp,         deserializerprovider dp, serializationconfig sconfig,         deserializationconfig dconfig) {     super(jf, sp, dp, sconfig, dconfig); }  public liferayobjectmapper(jsonfactory jf, serializerprovider sp,         deserializerprovider dp) {     super(jf, sp, dp); }  public liferayobjectmapper(jsonfactory jf) {     super(jf); }     @override public boolean candeserialize(javatype type) {      deserializationconfig desconfig = copydeserializationconfig();     addmixinannotations(desconfig, type);     return _deserializerprovider.hasvaluedeserializerfor(desconfig, type); }  /***************************************************************************  * <b>description:</b> adds mix in annotations filter out  * entity internal fields expando prevent deserialization  *   * <b>created:</b>20 feb 2014 16:57:31  @author vitor silva   * @param desconfig   **************************************************************************/ protected void addmixinannotations(deserializationconfig desconfig, javatype type) {     desconfig.addmixinannotations(type.getclass(), ignoreexpandoattributesmixin.class);  }  abstract class ignoreexpandoattributesmixin {      @jsonignore public abstract void setexpandobridgeattributes(servicecontext servicecontext);      @jsonignore public abstract void setexpandobridgeattributes(basemodel<?> basemodel);      @jsonignore public abstract void setexpandobridgeattributes(expandobridge expandobridge);  }

}

because using spring 4 need rewrite code jackson 2 (2.3.2) changed far:

package de.outsourcing.rest.json;  import com.fasterxml.jackson.annotation.jsonignore; import com.fasterxml.jackson.core.jsonfactory; import com.fasterxml.jackson.databind.deserializationconfig; import com.fasterxml.jackson.databind.javatype; import com.fasterxml.jackson.databind.objectmapper; import com.fasterxml.jackson.databind.deser.defaultdeserializationcontext; import com.fasterxml.jackson.databind.ser.defaultserializerprovider; import com.liferay.portal.model.basemodel; import com.liferay.portal.service.servicecontext; import com.liferay.portlet.expando.model.expandobridge;    /***************************************************************************  * <b>description:</b> objectmapper add mixin annotations  * make service builder entities valid jackson   * deserialization  * <b>created:</b>20 feb 2014 17:48:09  @author vitor silva   **************************************************************************/ @suppresswarnings("serial") public class liferayobjectmapper extends objectmapper {  public liferayobjectmapper() {     super(); }  public liferayobjectmapper(jsonfactory jf, defaultserializerprovider sp,          defaultdeserializationcontext ddc) {     super(jf, sp, ddc); }     public liferayobjectmapper(jsonfactory jf) {     super(jf); }     @suppresswarnings("deprecation") @override public boolean candeserialize(javatype type) {      deserializationconfig desconfig = getdeserializationconfig();     addmixinannotations(desconfig, type);     return _deserializationcontext.hasvaluedeserializerfor(type); }  /***************************************************************************  * <b>description:</b> adds mix in annotations filter out  * entity internal fields expando prevent deserialization  *   * <b>created:</b>20 feb 2014 16:57:31  @author vitor silva   * @param desconfig   **************************************************************************/ protected void addmixinannotations(deserializationconfig desconfig, javatype type) {     desconfig.addmixinannotations(type.getclass(), ignoreexpandoattributesmixin.class);  }  abstract class ignoreexpandoattributesmixin {      @jsonignore public abstract void setexpandobridgeattributes(servicecontext servicecontext);      @jsonignore public abstract void setexpandobridgeattributes(basemodel<?> basemodel);      @jsonignore public abstract void setexpandobridgeattributes(expandobridge expandobridge);  }

}

the method 

protected void addmixinannotations(deserializationconfig desconfig, javatype type) {     desconfig.addmixinannotations(type.getclass(), ignoreexpandoattributesmixin.class);

is not valid. specific .addmixinannotations not available in jackson2 obejct deserializationconfig.

how must change jackson2 ???

minify - Minimizing css files -

i want know how css files can minimized. currently, using external sites css minifier compress css files. however, after removing whitespaces, comments, etc, file sizes reduced 10-15%. how frameworks bootstrap manage make minimized versions kilobytes. as example, css is: body { background-color: #ff0; } the reduction goes 28 bytes 22 bytes other css files have lot more characters still smaller this. actually minifying code means it's remove thing code white space characters new line characters comments block delimiters it reduces amount of code has transferred on web , speed site load fastly.but unreadable format.

Add a dynamic header in angular 2 http provider -

i have http interceptor built via tutorial https://scotch.io/@kashyapmukkamala/using-http-interceptor-with-angular2 the problem need have dynamic header changes automatically once changes 'mode' in app. service able tell interceptor change header, or have interceptor pull header (which string)from service each request. able throwing away patch method, call http.patch('new header string') set header string. call in service controls 'mode' setting. wondering if there way interceptor pull recent value service each request or if can add method http provider via interceptor? i've tried call service in interceptor each request returns undefined. because creating new instance of service or copying value before service fired , loaded/changed data. i don't want pass header string every http provider call because defeats purpose of having interceptor, id able set once changes or have provider fetch service before makes request. tl;dr : need add autom
