I am currently using Hibernate 3 and Spring 3.0. I want to migrate to Hibernate 4 and Spring 3.2. I am using a subclass of AbstractLobType to implement a UserType that maps from an InputStream to the database (MySQL LONGBLOB):
import java.io.InputStream;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Types;
import org.hibernate.HibernateException;
import org.springframework.jdbc.support.lob.LobCreator;
import org.springframework.jdbc.support.lob.LobHandler;
import org.springframework.orm.hibernate3.support.AbstractLobType;
public class BlobUserType extends AbstractLobType {
public int[] sqlTypes() {
return new int[] { Types.BLOB };
}
public Class returnedClass() {
return InputStream.class;
}
#Override
protected Object nullSafeGetInternal(ResultSet rs, String[] names, Object owner, LobHandler lobHandler)
throws SQLException, HibernateException {
return lobHandler.getBlobAsBinaryStream(rs, names[0]);
}
#Override
protected void nullSafeSetInternal(PreparedStatement ps, int index, Object value, LobCreator lobCreator)
throws SQLException, HibernateException {
if (value != null) {
lobCreator.setBlobAsBinaryStream(ps, index, (InputStream) value, -1);
} else {
lobCreator.setBlobAsBytes(ps, index, null);
}
}
}
Since AbstractLobType is in the hibernate3, I should not use it anymore, but what is the alternative?
I did read this JIRA issue on the spring project, but it does not help me at all.
This is the hibernate mapping:
<class name="SoundNotification" table="SoundNotification" entity-name="SoundNotificationWithData">
<id name="m_id" type="int" column="id" unsaved-value="-1">
<generator class="native"/>
</id>
<property name="m_name" column="name" unique="true" not-null="true"/>
<property name="m_data" column="data"
type="com.mycompany.server.common.service.persistence.impl.hibernate.usertype.BlobUserType"
not-null="true"/>
<property name="m_size" formula="OCTET_LENGTH(data)"/>
<property name="m_inUse"
formula="(select count(1) from EventTypeConfiguration etc where etc.soundNotification=id)"/>
</class>
And the Java class:
public class SoundNotification extends IntegerEntity
{
private String m_name;
private transient InputStream m_data;
private boolean m_inUse;
private long m_size;
// getters and setters ...
}
UPDATE with MaterializedBlobType:
My TrafficMap.hbm.xml:
<class name="TrafficMapImage" table="TrafficMapImage" entity-name="TrafficMapImageWithData">
<id name="m_id" column="id" type="int" unsaved-value="-1">
<generator class="native"/>
</id>
<property name="m_created" column="created" type="org.jadira.usertype.dateandtime.joda.PersistentDateTime"
not-null="true"/>
<property name="m_image" column="image"
type="org.hibernate.type.MaterializedBlobType"
not-null="true"/>
<property name="m_type" column="type" not-null="true">
<type name="com.traficon.tmsng.server.common.service.persistence.impl.hibernate.usertype.EnumUserType">
<param name="enumClass">com.traficon.domain.map.TrafficMapImageType</param>
</type>
</property>
</class>

In theory you should use the hibernate provided MaterializedBlobType if you want to use InputStreams for your Blob then add the following property to you hibernate configuration
hibernate.jdbc.use_streams_for_binary=true
This will instruct the MaterializedBlobType to use an InputStream instead of a byte[].
I ended up creating my own UserType that converts between Blob and InputStream:
import org.hibernate.HibernateException;
import org.hibernate.engine.spi.SessionImplementor;
import org.hibernate.usertype.UserType;
import java.io.InputStream;
import java.io.Serializable;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Types;
public class BlobUserType implements UserType
{
// ------------------------ INTERFACE METHODS ------------------------
// --------------------- Interface UserType ---------------------
#Override
public int[] sqlTypes()
{
return new int[]{Types.BLOB};
}
#Override
public Class returnedClass()
{
return InputStream.class;
}
#Override
public boolean equals( Object x, Object y ) throws HibernateException
{
boolean result;
if (x == y)
{
result = true;
}
else if (x == null || y == null)
{
result = false;
}
else
{
result = x.equals( y );
}
return result;
}
#Override
public int hashCode( Object x ) throws HibernateException
{
return x.hashCode();
}
#Override
public Object nullSafeGet( ResultSet rs, String[] names, SessionImplementor session, Object owner ) throws HibernateException, SQLException
{
return rs.getBlob( names[0] ).getBinaryStream();
}
#Override
public void nullSafeSet( PreparedStatement st, Object value, int index, SessionImplementor session ) throws HibernateException, SQLException
{
if( value != null )
{
InputStream inputStream = (InputStream)value;
st.setBlob( index, inputStream );
}
else
{
st.setNull( index, Types.BLOB );
}
}
#Override
public Object deepCopy( Object value ) throws HibernateException
{
return value;
}
#Override
public boolean isMutable()
{
return false;
}
#Override
public Serializable disassemble( Object value ) throws HibernateException
{

}
#Override

}
#Override

Seems to be working fine loading and saving my entity from/to the database.
You should not use AbstractLobType because it is in the hibernate 3 as you said.
You can create your own UserType to convert between Blob and InputStream. However, if you are migrating existing data from Hibernate 3 to 4, your code will not work:
The format of BlobSerializableType has header's information in addition which is something like this:
’ t{"userServices":[{"accountStatus":"PendingTermsAndConditions","serviceIdentifier":"SNG"}]...}]}
Your code will working (reading, writing) to the format without header:
{"userServices":[{"accountStatus":"PendingTermsAndConditions","serviceIdentifier":"SNG"}]...}]}
My personal solution is to simulate the Hibernate 3 to write and read Blob data as below:
package com.newbay.acs.domain.hibernate;
import org.apache.commons.io.IOUtils;
import org.hibernate.HibernateException;
import org.hibernate.engine.spi.SessionImplementor;
import org.hibernate.usertype.UserType;
import java.io.*;
import java.nio.charset.StandardCharsets;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Types;

Liberty does not support the WsnInitialContextFactory class. You can just do this (and it'll work in WebSphere traditional as well):
try {
Context ctx = new InitialContext(new Hashtable());
try {
ds = (DataSource) ctx.lookup("java:comp/env/" + jndiName);
} catch (Exception ex) {
LogUtil.debugException("DBConnectionManager", "Exception in init: Resource reference DataSource lookup Error.", "init()", ex, "");
try {
ds = (DataSource) ctx.lookup("jdbc/" + jndiName);
} catch (Exception exp) {
LogUtil.debugException("DBConnectionManager", "Exception in init: Datasource lookup Error.", "init()", exp, "");
}
}
I have a problem with my project in Spring. Firstly I couldn't run it on the server but after downloading all resources again it started.
But now I have some imports which Spring can not see
For example:
import org.springframework.context.annotation.ComponentScan can not be resolved as a type.
and autwired value
#ComponentScan can not be resolved as a type.
Because of that hibernate is not creating tables in my database ( I think so )
Also two configuration classes have some errors:
The hierarchy of the type Spring4Initializer is inconsistent
SpringSecurityInitializer
public class Spring4Initializer extends AbstractAnnotationConfigDispatcherServletInitializer {
#Override
protected Class<?>[] getRootConfigClasses() {
return new Class[] { Spring4Configuration.class };
}
#Override
protected Class<?>[] getServletConfigClasses() {
return null;
}
#Override
protected String[] getServletMappings() {
return new String[] { "/" };
}
#Override
protected Filter[] getServletFilters() {
CharacterEncodingFilter characterEncodingFilter = new CharacterEncodingFilter();
characterEncodingFilter.setEncoding("UTF-8");
characterEncodingFilter.setForceEncoding(true);
return new Filter[] { characterEncodingFilter };
}
}
SpringSecurityInitializer Multiple markers at this line
- The type org.springframework.web.WebApplicationInitializer cannot be resolved. It is indirectly referenced from
required .class files
import org.springframework.security.web.context.AbstractSecurityWebApplicationInitializer;
public class SpringSecurityInitializer extends AbstractSecurityWebApplicationInitializer {
}

Does anyone know what should I do with it to make hibernate working?
In Outline tree my function GetHibernateProperites() is marked as red
Have you included the spring-context in your maven dependencies? I think you are missing that dependency.
I'm currently trying to develop a custom Jira plugin, which also uses a servlet to render a Soy template.
This is the code of my servlet:
/*
* To change this license header, choose License Headers in Project Properties.
* To change this template file, choose Tools | Templates
* and open the template in the editor.
*/
package at.fraiss.plugins.custommenuitem.servlets;
import javax.servlet.*;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import com.atlassian.soy.renderer.SoyTemplateRenderer;
import java.util.HashMap;
import java.util.Map;
/**
*
* #author Mario
*/
public class SoyTemplateServlet extends HttpServlet {
private SoyTemplateRenderer soyTemplateRenderer;
public SoyTemplateServlet(SoyTemplateRenderer soyTemplateRenderer)
{
this.soyTemplateRenderer = soyTemplateRenderer;
}
#Override
public void doGet(HttpServletRequest request, HttpServletResponse response) throws IOException, ServletException
{
response.setContentType("text/html");
response.getWriter().write(getHtml());
}
public String getHtml()
{
Map<String, Object> data = new HashMap<String,Object>();
data.put("isLocal", true);
data.put("url", "http://www.example.com");
data.put("title", "example");
return this.soyTemplateRenderer.render("jira.webresources:soy-templates", "JIRA.Templates.Links.helpLink", data);
}
}
This is how I defined the soy template files inside the atlassian-plugin.xml descriptor:
<web-resource key="soy-templates">
<dependency>com.atlassian.soy.soy-template-plugin:soy-deps</dependency>
<!-- Available to the server-side only -->
<resource type="soy" name="links" location="links.soy"/>
<!-- Make available to the client-side in JS as well... -->
<transformation extension="soy">
<transformer key="soyTransformer"/>
</transformation>
<resource type="download" name="Links.soy.js" location="links.soy"/>
</web-resource>
I have added the following section to my pom.xml:
<dependency>
<groupId>com.atlassian.soy</groupId>
<artifactId>soy-template-renderer-api</artifactId>
<version>4.0.4</version>
<scope>provided</scope>
</dependency>
and always get this error when try to acces the servlet

I also had this problem (and lost hours on it).
The Spring scanner apparently only processes classes marked with #Named.
This worked for me:
#Named("MyServlet")
public class MyServlet extends HttpServlet{
#ComponentImport
private final SoyTemplateRenderer soyTemplateRenderer;
#Inject
public MyServlet(#ComponentImport final SoyTemplateRenderer soyTemplateRenderer) {
this.soyTemplateRenderer = soyTemplateRenderer;
}
}
Apparently this has nothing to do with jiira, but in your frustration you seem to be blaming it and its documentation. It's actually a problem with your use of spring, and your apparent inability to read stack traces.
The first entry in the stack trace mentions, in may different ways, No qualif
ying bean of type [com.atlassian.soy.renderer.SoyTemplateRenderer] found. So, you seem to have not provided a bean definition for the SoyTemplateRenderer for spring to find. Rectify this and this particular problem will disappear.

It looks like this Storm ticket has a relevant discussion:
https://issues.apache.org/jira/browse/STORM-122
I think Accumulo has an slf4j-log4j12 dependency, and Storm uses log4j-over-slf4j which is incompatible. The discussion seems to suggest excluding logging dependencies like slf4j-log4j12 and log4j from your Accumulo dependency. I don't know if this will work, but it's worth a try.
As part of the database upgrade for an existing application, a custom Liquibase change which extends AbstractChange has been created:
#DatabaseChange(name = "springBeanChange", description = "Runs a spring bean custom change", priority = ChangeMetaData.PRIORITY_DEFAULT)
public class SpringBeanChange extends AbstractChange {
private String beanName;
private String changeClass;
#DatabaseChangeProperty(description = "Spring bean name (optional)")
public String getBeanName() {
return this.beanName;
}
public void setBeanName(final String beanName) {
this.beanName = beanName;
}
#DatabaseChangeProperty(description = "Spring bean class")
public String getChangeClass() {
return this.changeClass;
}
public void setChangeClass(final String changeClass) {
this.changeClass = changeClass;
}
private CustomTaskChange bean;
#Override
public boolean generateStatementsVolatile(final Database database) {
return true;
}
#Override
public String getConfirmationMessage() {

}
#Override
public SqlStatement[] generateStatements(final Database database) {
try {
findBean().execute(database);
} catch (CustomChangeException e) {
throw new UnexpectedLiquibaseException(e);
}
return new SqlStatement[0];
}
#SuppressWarnings("unchecked")
private CustomTaskChange findBean() {
Class<CustomTaskChange> requiredType = CustomTaskChange.class;
if (this.changeClass != null) {
try {
Class<?> requestedType = Class.forName(this.changeClass);
if (CustomTaskChange.class.isAssignableFrom(requestedType)) {
requiredType = (Class<CustomTaskChange>) requestedType;
} else {
throw new UnexpectedLiquibaseException(
"Specified changeClass " + this.changeClass
+ " was not an instance of "
+ CustomTaskChange.class);
}
} catch (ClassNotFoundException e) {
throw new UnexpectedLiquibaseException(
"Could not create change class", e);
}
}
if (this.bean == null) {
if (getBeanName() == null) {
this.bean = SpringContextHolder.getInstance().getContext()
.getBean(requiredType);
} else {
this.bean = SpringContextHolder.getInstance().getContext()
.getBean(getBeanName(), requiredType);
}
}
return this.bean;
}
#Override
public ValidationErrors validate(final Database database) {
try {
return findBean().validate(database);
} catch (NullPointerException p_exception) {
return new ValidationErrors()
.addError("Exception thrown calling validate():"
+ p_exception.getMessage());
} catch (UnexpectedLiquibaseException p_exception) {
return new ValidationErrors()

} catch (BeansException p_exception) {
return new ValidationErrors()
.addError("Exception thrown calling validate():"

}
}
}
This is then configured in the database change log XML file as follows:
<changeSet id="15" author="theauthor">
<XXX:springBeanChange
changeClass="XXX.XXX.XXX.upgrade.tasks.TaskUpgrade" />
</changeSet>
Where TaskUpgrade implements CustomTaskChange and is the class that is returned get the call to getBean in SpringBeanChange.
The database change log file also contains many 'normal' liquibase commands such as addColumn.
A custom Java class has then been written which actually performs the upgrade (the following lines show the important lines of code which actually do the upgrade). This Java program is manually executed after the application has been deployed onto the server:
Liquibase liquibase =
new Liquibase(getChangeLogFile(), new ClassLoaderResourceAccessor(), new JdbcConnection(conn));
if ("update".equalsIgnoreCase(command)) {
liquibase.update(contexts);
} else {
throw new IllegalArgumentException("Unknown command " + command);
}
This works fine and executes the database upgrade.
I'm looking to avoid the need to use the custom Java program to perform the upgrade and actually do it when the application starts up. The app already uses Spring so it makes sense to to the upgrade when the Spring context is initialising.
To do this, I've added the following to the applicationContext file:
<bean id="myLiquibase" class="liquibase.integration.spring.SpringLiquibase">
<property name="dataSource" ref="dataSource" />
<property name="changeLog" value="classpath:databaseChangeLog.xml" />
<property name="contexts" value="test, production" />
</bean>
However, when the application starts up, I get the following exception:
2014-03-25 13:02:16,097 [main] ERROR context.ContextLoader - Context initialization failed
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'myLiquibase' defined in class path resource [applicationContext.xml]: Invocation of init method failed; nested exception is liquibase.exception.ChangeLogParseException: Invalid Migration File: Unknown Liquibase extension: springBeanChange.

I can't find anything on the Liquibase site or anywhere else which provides any help as to what JAR I'm missing (if indeed I am missing one) or if anything else is missing/not defined.
Does anyone have any ideas?
Thanks in advance.
The jar that contains the custom extension is what is missing from your classpath. I don't use Spring, so I don't know how it sets up the classpath, but you probably need to either put the jar in a standard location so Spring can find it or else configure the Spring classpath.
