Get file from repository using Atlassian Bitbucket API

I have a Java Application that implements a hook using the Atlassian Bitbucket API.
The class that implements the hook is defined as follows:
import com.atlassian.plugin.spring.scanner.annotation.export.ExportAsService;
import com.atlassian.bitbucket.hook.repository.PreRepositoryHook;
import com.atlassian.bitbucket.hook.repository.RepositoryHookRequest;
import com.atlassian.bitbucket.hook.repository.PreRepositoryHookContext;
import com.atlassian.bitbucket.hook.repository.RepositoryHookResult;
import com.atlassian.bitbucket.hook.repository.PreRepositoryHookRequest;
import com.atlassian.bitbucket.repository.Repository;
import javax.annotation.Nonnull;
/* Other imports */
#ExportAsService({SCMAdapter.class})
public class SCMAdapter implements PreRepositoryHook<RepositoryHookRequest>, ISCMAdapter{
/*Methods from both interfaces*/
}
The methods from the ISCMAdapter interface are irrelevant for this problem.
The PreRepositoryHook interface contains two methods. One of them is the following:
public RepositoryHookResult preUpdate(#Nonnull PreRepositoryHookContext context, #Nonnull RepositoryHookRequest request){
/*Returns a RepositoryHookResult object */
}
I can obtain the repository involved in the hook with the following call:
Repository repo = request.getRepository();
From that object, I can obtain the project's key, the slug, the ID, the name and the state:
String pkey=repo.getProject().getKey();
String slug=repo.getSlug();
String name=repo.getName();
int id=repo.getId();
Repository.State state=repo.getState();
The method is currently working fine. However, I got a requirement that each repository must have a hidden directory with the same name for all repositories (lets say ".myHiddenDir") and that directory must contain a YAML file named config.yml
Is it possible, with the information obtained as listed above to obtain the content of an specific file in the repo?
Thanks in advance.
P.D.: If you find that this description is lacking more info, please let me know and I will check the code.

MyBatis 3.1.1, how to execute custom SQL code directly

I use PostrgeSQL 9.6 and MyBatis 3.1 (under there is also Java 8 and Spring), and I need to execute a custom query, which I create dynamically with a StringBuilder because of it's complexity.
How can I pass it to my class mapper.xml file ?
I've heard about #SelectProvider, but ? can't find complete examples... Can someone give me a step by step guide ?
I was also reading of The SQL Builder Class, of MyBatis, following the official guide but I miss how to launch that query/object I've created. By the way this doesn't seems the right way to me, because of the complexity of the query I have to build. Following the guide it seems I can't use contidional operators like IF or FOR to create the query string... So it can't work for my use.
thanks.

I only use #SelectProvider for java annotation ,this is a easy way to use it ,
this is my simple example earlier this year
1. create your provider class
package com.mybatis;
import java.util.Map;
import java.util.logging.Logger;
import org.apache.ibatis.annotations.Param;
import org.apache.ibatis.jdbc.SQL;
public class SqlProvider {
public String sqlProvider(Map<String, Object> map){
Logger.getLogger(SqlProvider.class.getName()).info("select * from student where id="+map.get("0"));
return "select * from student where id="+map.get("0");
}
public String findById(#Param("id") int id){
return new SQL(){{
SELECT("id,name,info");
FROM("student");
WHERE("id="+id);
}
}.toString();
}
}
you can use a string produce your sql query ,but also new SQL(){{some clauses such as SELECT(string),WHERE(string) etc.
}}.toString();
2. use your provider class in Mapper interface
we can use #SelectProvider(type=Class,method="methodName")
specified class and method
package com.mybatis;
import java.util.List;
import java.util.Map;
import org.apache.ibatis.annotations.Delete;
import org.apache.ibatis.annotations.Insert;
import org.apache.ibatis.annotations.Mapper;
import org.apache.ibatis.annotations.Options;
import org.apache.ibatis.annotations.Param;
import org.apache.ibatis.annotations.Result;
import org.apache.ibatis.annotations.Results;
import org.apache.ibatis.annotations.Select;
import org.apache.ibatis.annotations.SelectProvider;
import org.apache.ibatis.annotations.Update;
/*
*
*Stu is an entity map to your table in db
*
*/
#Mapper
public interface StuMapper {
#SelectProvider(type=SqlProvider.class,method="sqlProvider")
public Stus sqlProvider(Map<String, Object> map);
#SelectProvider(type=SqlProvider.class,method="findById")
public Stus findById_(#Param("id") int id);
}
Last , using you mapper .
more details ,see https://github.com/v5developer/maven-framework-project/blob/master/reference/Java.Persistence.with.MyBatis.3.pdf
especially in chapter 4.

<select id="methodName" resultMap="alarmPieEntry">
${your_raw_sql}
</select>
Just use ${your_raw_sql} variables in myClass_mapper.xml file , don't use #{your_raw_sql} .

How to access AEM Core models in a Sling model

Specifically, I am trying to enable .SVG files to be usable by the core image component.
Right now I am making a sling model that ideally I would like to access the returned values of the getSrc() and getFileReference() classes in the core AEM Component interface located here.
I am very new to AEM development and Sling models. Am I missing some vital functionality that would let me do this?
Here is my code, which probably isn't at all helpful at this point.
package com.site.core.models;
import com.adobe.cq.wcm.core.components.models.Image;
import org.apache.sling.api.SlingHttpServletRequest;
import org.apache.sling.api.resource.Resource;
import org.apache.sling.api.resource.ResourceResolver;
import org.apache.sling.api.resource.ValueMap;
import org.apache.sling.models.annotations.*;
import org.apache.sling.models.annotations.injectorspecific.*;
import org.apache.sling.settings.SlingSettingsService;
import javax.jcr.Node;
import java.util.regex.Matcher;
import java.util.regex.Pattern;
import javax.inject.Inject;
#Model(adaptables = SlingHttpServletRequest.class)
public class ImageModel {
private String src = Image.getSrc();
return src;
}

As I mentioned in my comment, the link you are referring to is an interface, the implementation of that interface is here
In order to use your own implementation, you have two options:
In the image component html, change the data-sly-use to refer to your impl: com.site.core.models.ImageModel
Create a separate model that implements the Image interface and give it a high ranking to be picked up instead of the existing impl.
Disclaimer: I have not tested #2 but the documentation suggests that it's possible.

Create a Table/Query with JPA/Hibernate in Play Framework

So I have Play Framework running at the moment with JPA and Hibernate. I'm completely new to both and the tutorials I've found around the web are above my head.
How in the world can I send a simple query or create a table? This is example code I've written up and I get: "RuntimeException: No EntityManager bound to this thread. Try wrapping this call in JPA.withTransaction, or ensure that the HTTP context is setup on this thread."
package controllers;
import play.Logger;
import javax.persistence.Entity;
import javax.persistence.EntityManager;
import javax.persistence.EntityManagerFactory;
import javax.persistence.EntityTransaction;
import javax.persistence.Persistence;
import javax.persistence.Query;
import play.db.jpa.JPA;
import play.mvc.Controller;
import play.db.*;
public class Database {
public static void initbuild() {
Logger.info("Checking database structure. The database will be restructured if not in the correct format.");
JPA.em().createQuery("create table test");
}
}

Le'ts start saying that you don't want to build the tables by yourself, just write your models under the models package annotating them by #Entity and the JPA plugin will automagically generate the tables matching the models that you have defined.
As for the error the error is raised cause you should annotate the method with the #Transactional annotation.
As stated in the official doc http://www.playframework.com/documentation/2.3.x/JavaJPA
"Every JPA call must be done in a transaction so, to enable JPA for a particular action, annotate it with #play.db.jpa.Transactional. This will compose your action method with a JPA Action that manages the transaction for you"
Hope it helped btw reading the doc and have a look to the computer-jpa example is suggested

Java generated code from wadl don't have implementation

I'm new to java code generation from WADL, I used cxf-wadl2java-plugin and it works fine, the problem is that the generated code contains the resource code but no implementation as such:
/**
* Created by Apache CXF WadlToJava code generator
**/
package wadl.client;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.QueryParam;
import wadl.Response;
#Path("/path")
public class PathResource {
#GET
#Produces({"application/xml", "application/json" })
public Response get(#QueryParam("q") String q, #QueryParam("attr") String attr) {
//TODO: implement
return null;
}
}
Is there any mean to get an implementation when the code generation is done?
How do I us this class (injection??)?
How do I set the data return type? (json, xml, Response object?)
Thanks for your help

According to the Wikipedia Page:
WADL models the resources provided by a service and the relationships
between them
It however, does not state anything on the logic behind such resources.
Long story short, the WADL should explain/point out what resources must your system expose, however it does not explain how are these resources implemented, which is usually ideal since Web Services are usually used to simply expose a set of functionalities.
