I'm trying to write a XML fragment containing a CData element in Spring StaxtItemWriter and Jaxb marshaller. But the output is either:
not wrap with <![CDATA[ ... ]]>
or escaped: < and > replaced by < and >
First, the item writer:
<bean id="userAuthorizationErrorItemWriter"
class="org.springframework.batch.item.xml.StaxEventItemWriter">
<property name="rootTagName" value="UserAuthorizationEvent" />
<property name="rootElementAttributes">
<map>
<entry key="xmlns:xsi" value="http://www.w3.org/2001/XMLSchema-instance" />
</map>
</property>
<property name="marshaller" ref="userAuthorizationTypeMarshaller" />
<property name="overwriteOutput" value="true" />
<property name="resource" value="file://C:/TEMP/fichierOUT.xml" />
<property name="transactional" value="false" />
</bean>
Then the JAXB marshaller
<bean id="userAuthorizationTypeMarshaller" class="org.springframework.oxm.jaxb.Jaxb2Marshaller">
<property name="contextPath" value="com.usecase1.xsd.model"/>
</bean>
The java class (simplified):
#XmlAccessorType(XmlAccessType.FIELD)
#XmlType(name = "UserAuthorizationType", propOrder = {"action"})
#XmlRootElement(name = "UserAuthorization")
public class UserAuthorizationType {
#XmlElement(name = "Action", required = true)
protected String action;
public String getAction() {
return action;
}
public void setAction(String value) {
this.action = value;
}
}
When writing to file, I want that the Action value to be encapsulate into a <![CDATA[ ... ]]> block.
I tried using a #XmlJavaTypeAdapter(Adapter1.class) that return:
public String marshal(String value) {
return "<![CDATA[" + value + "]]>";
}
But the output is escaped:
<UserAuthorization><Action><![CDATA[first, second, third]]></Action></UserAuthorization>
Do you have any idea?
You will have to create a custom XML marshaller and register the elements that should be output as CDATA. See if this example helps https://jaxb.java.net/faq/JaxbCDATASample.java

Here's the DAO file which the error says as not writable:

Adding my model which contains the setters and getters (mnpTranslation.java):

}
public void setAction (String action) {

}
}
[edit] I'm adding the rest of my java files so you could see more what I'm dealing with right now. Thanks a lot for checking this.

public void save (mnpTranslation mnp) {
this.mnpTranslationDAO.save(mnp);
}
}
mnpTranslationMapper.java:
package com.e_horizon.jdbc.mnpTranslation;

mnp.setAction(result.getString("action"));
return mnp;
}
}
Please let me know if there's anything else you need to see. I'd gladly post it right away. Any help will be much appreciated.
The error message states that the problem is with your mnpTranslationServiceImpl class.

Bean property 'mnpTranslationDAO' is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?
I have bean class as below -
public class Account {
private String strAccNumber = "";
private List<Account> accountList = new ArrayList<Account>();
// getter setter
....
...
#Override
public String toString() {
// code for PassThroughLineAggregator
String data="";
for (int j=0; j<accountList.size(); j++) {
Account bean = accountList.get(j);
data = data + bean.getStrAccNumber();
if (j<(accountList.size()-1)) {
data = data + "\n";
}
}
return data;
}
}
to write data I want to set accountList in my config file.
I'm using below code to set bean property.
<bean id="flatFileReader" class="org.springframework.batch.item.file.FlatFileItemReader"

AccountItemProcessor -
public class AccountItemProcessor implements ItemProcessor<Account, List<Account>>{
#Override
public List<Account> process(Account accObj) throws Exception {
// logic..
}
After processing single record in the process step I want to write multiple items(list of item) , how can I write multiple item at a time using arraylist. In my case I want to write data from accountlist.
You'll want to implement your own LineAggregator. That is what provides the String to be written to the file. In your case, you'll write one that returns a String that is really multiple lines.
You can read more about the LineAggregator interface in the documentation here: http://docs.spring.io/spring-batch/apidocs/org/springframework/batch/item/file/transform/LineAggregator.html
How get VelocityEngine with Velocity Tools in Spring 3?
I need a method in the controller to process a template Velocity, but need to have Velocity Tools that are available to initialize the Spring 3.
Now I'm doing it like this.
Spring Config:
<bean id="velocityConfig" class="org.springframework.web.servlet.view.velocity.VelocityConfigurer">
<property name="resourceLoaderPath" value="/WEB-INF/velocity/"/>
<property name="velocityProperties">
<props>
<prop key="input.encoding">UTF-8</prop>
<prop key="output.encoding">UTF-8</prop>
</props>
</property>
</bean>
<bean id="viewResolver" class="org.springframework.web.servlet.view.velocity.VelocityViewResolver">
<property name="cache" value="false"/>
<property name="prefix" value=""/>
<property name="suffix" value=".html"/>
<property name="contentType" value="text/html; charset=UTF-8"/>
<property name="toolboxConfigLocation" value="/WEB-INF/velocity/config/toolbox.xml"/>
<property name="viewClass" value="my.tools.VelocityToolsView"/>
</bean>
In controller class:
#Autowired
private VelocityConfigurer configurer;
private VelocityEngine velocityEngine;
private ToolContext toolContext;
#PostConstruct
public void init() {
velocityEngine = configurer.getVelocityEngine();
ToolManager toolManager = new ToolManager();
toolManager.configure("fuulPath/WEB-INF/velocity/config/toolbox.xml");
toolContext = toolManager.createContext();
}
In method:
VelocityContext velocityContext = new VelocityContext(map, toolContext);
StringWriter writer = new StringWriter();
velocityEngine.mergeTemplate("myTeplate.html", "UTF-8", velocityContext, writer);
String templateString = writer.toString();
The above method to get velocity is good when you don't use Spring configuration.When you use Spring you don't need this much complexity.
Define this bean in your spring.xml
<bean id="velocityEngine"
class="org.springframework.ui.velocity.VelocityEngineFactoryBean">
<property name="velocityProperties">
<value>
resource.loader=class
class.resource.loader.class=org.apache.velocity.runtime.resource.loader.ClasspathResourceLoader
</value>
</property>
</bean>
and In your java class Autowire this bean
#Component
public class Sample {
private VelocityEngine velocityEngine;
public VelocityEngine getVelocityEngine() {
return velocityEngine;
}
#Autowired
#Required
public void setVelocityEngine(VelocityEngine velocityEngine) {
this.velocityEngine = velocityEngine;
}
public String getSomething(Object variable) {
Map model = new HashMap();
model.put("variable",variable);
return VelocityEngineUtils.mergeTemplateIntoString(velocityEngine, "/templates/sometemp.vm", model);
}
}
There is a simpler way to do it in Spring 3
add toolbox.xml to WEB-INF/velocity
<?xml version="1.0" encoding="UTF-8"?>
<toolbox>
<xhtml>true</xhtml>
<tool>
<key>date</key>
<scope>application</scope>
<class>org.apache.velocity.tools.generic.DateTool</class>
<parameter name="format" value="dd/MM/yyyy" />
</tool>
<tool>
<key>display</key>
<scope>application</scope>
<class>org.apache.velocity.tools.generic.DisplayTool</class>
</tool>
<tool>
<key>math</key>
<scope>application</scope>
<class>org.apache.velocity.tools.generic.MathTool</class>
</tool>
<tool>
<key>iter</key>
<scope>application</scope>
<class>org.apache.velocity.tools.generic.IteratorTool</class>
</tool>
<tool>
<key>sort</key>
<scope>application</scope>
<class>org.apache.velocity.tools.generic.SortTool</class>
</tool>
<tool>
<key>esc</key>
<scope>application</scope>
<class>org.apache.velocity.tools.generic.EscapeTool</class>
</tool>
</toolbox>
Then add this path to your APPNAME-servlet.xml file
<bean id="viewResolver" class="org.springframework.web.servlet.view.velocity.VelocityViewResolver" p:cache="false" p:order="1">
<property name="prefix" value="/com/aol/dragon/template/"/>
<property name="suffix" value=".vm"/>
<property name="toolboxConfigLocation" value="/WEB-INF/velocity/toolbox.xml" />
</bean>
Then update you pom.xml dependency
<dependency>
<groupId>org.apache.velocity</groupId>
<artifactId>velocity-tools</artifactId>
<version>2.0</version>
</dependency>
save, update project, and run the server. You should be now able to use all tools stuff in vm's.
I am using spring 3.0 in my webapplication. I've got recently a problem in my application. I am using <mvc:annotation-drive/> tag in my spring-servlet.xml file but due to a requirement I've to remove this and place XML configuration instead.
But now my problem is it generates json output with quoted field names like if I return Boolean.TRUE I got "true" in the output. I want just true without quotes.
here is my XML configuration
<bean id="conversionService" class="org.springframework.format.support.FormattingConversionServiceFactoryBean" />

<bean id="jsonHttpMessageConverter"
class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter">
<property name="prefixJson" value="false"/>
<property name="supportedMediaTypes" value="application/json"/>
</bean>
any help would be much appreciable.
If you are using the FlexJSON plugin, you can create custom output for JSON. I am sure you can do that in Jackson too, but I have never done it. There is loads of examples on the FlexJSON site.
What happens if you return just the primitive value of true (or Boolean.TRUE.booleanValue() rather than the wrapped object version of Boolean.TRUE?
I believe that true and false values are hardcoded in Jackson library (writeBoolean is called even for the boxed booleans):
private final static byte[] TRUE_BYTES = { 't', 'r', 'u', 'e' };
#Override
public void writeBoolean(boolean state)
throws IOException, JsonGenerationException
{
_verifyValueWrite("write boolean value");
if ((_outputTail + 5) >= _outputEnd) {
_flushBuffer();
}
byte[] keyword = state ? TRUE_BYTES : FALSE_BYTES;
int len = keyword.length;
System.arraycopy(keyword, 0, _outputBuffer, _outputTail, len);
_outputTail += len;
}
so Jackson will never return double-quoted "true" in field values(if its behavior is not heavily overriden, for example with codecs).
So please check that MappingJacksonHttpMessageConverter methods are being invoked, and conversion is not performed somewhere else.
That is the default behavior, if you want your boolean values unquoted use a JAXB ContextResolver
Something like this
import java.util.HashMap;
import java.util.HashSet;
import java.util.Map;
import javax.ws.rs.ext.ContextResolver;
import javax.ws.rs.ext.Provider;
import javax.xml.bind.JAXBContext;
import com.sun.jersey.api.json.JSONJAXBContext;
#Provider
public class JAXBContextResolver implements ContextResolver<JAXBContext> {
private JAXBContext context;
private Class[] types = {SomeClass.class}; //Add the classes processed by JAXB and exposing boolean properties
public JAXBContextResolver() throws Exception {
Map props = new HashMap<String, Object>();
props.put(JSONJAXBContext.JSON_NOTATION, JSONJAXBContext.JSONNotation.MAPPED);
props.put(JSONJAXBContext.JSON_ROOT_UNWRAPPING, Boolean.TRUE);
java.util.HashSet<String> eprops = new HashSet<String>();
eprops.add("someBooleanProperty"); //add properties you want unquoted
props.put(JSONJAXBContext.JSON_NON_STRINGS, eprops);
this.context = new JSONJAXBContext(types, props);
}
public JAXBContext getContext(Class<?> objectType) {
return (types[0].equals(objectType)) ? context : null;
}
}
Hi i am developing a spring mvc app thats using hibernate to connect to a mysql database that stores files.
I have two methods. one that adds all files from a specific file path of my choosing and another method that invokes a query to return me a list of the files stored from mysql.
The issue is this. When i execute the first method on its own ie populating the database, it works fine i can see the contents of that table from mysql command line. however, when i then execute the query method right after populating it, the contents of that said table is completely gone instantly. Its as if hibernate only stored the data in the mysql temporarily or somewhere in mysql, it deleted data imediatly and doesnt keep it their.
this is the method that populated the table:
/**
* Test Method: ideal for another class to do this kind of work and this
* pass the FileObject into this class
*/
public void addSomeFiles() {
System.out.println("addSomeFiles");
File dir = new File(picturesPath);
String[] fileNames = dir.list();
for (int i = 0; i < fileNames.length; i++) {
System.out.println(fileNames[i]);
File file = new File(picturesPath + "\\" + fileNames[i]);
if (file.isFile()) {
FileObject fileO = contstructFileObject(file);
if (fileO == null) {
System.out.println("fileO is null!!!!!");
} else {
// addFile(fileO);
dbFileHelper.addFile(fileO);
}
}
}
System.out.println("//////////////");
// File file;
}
.........Hibernate template class........
public class DbFileHelper implements DbFileWrapper {
private HibernateTemplate hbTemplate;
//private static final String SQL_GET_FILE_LIST = "select filename, size, id, type from fileobject";
private static final String SQL_GET_FILE_LIST = "select new FileObject(filename, size, id, type) from FileObject";
public DbFileHelper() {
}
public void setHbTemplate(HibernateTemplate hbTemplate) {
System.out.println("setHbTemplate");
System.out.println("///////////////////");
System.out.println("///////////////////");
System.out.println("///////////////////");
this.hbTemplate = hbTemplate;
}
// ////////////////////////////////////////////////
#Override
public String addFile(FileObject file) {
// TODO Auto-generated method stub
System.out.println("addFile using hibernate");
if (hbTemplate == null) {
System.out.println("hbTemplate is null!! why?");
}
hbTemplate.saveOrUpdate(file);
hbTemplate.flush();
return "added succesfuly";
}
And here is the other method that makes the query:
........................
public JSONArray getFileList(String type){
return constructJsonArray(dbFileHelper.getFileList(ALL));
}
private JSONArray constructJsonArray(List<FileObject> fileList ){
JSONArray mJsonArray = new JSONArray();
for (int i = 0; i < fileList.size(); i++) {
System.out.println("fileName = " + fileList.get(i).getFilename() );
//mJson.put("Filename", fileList.get(i).getFileName() );
mJsonArray.add( new JSONObject().put("File ID", fileList.get(i).getId() ));
mJsonArray.add( new JSONObject().put("Filename", fileList.get(i).getFilename() ));
mJsonArray.add( new JSONObject().put("File type", fileList.get(i).getType()));
mJsonArray.add( new JSONObject().put("File Size", fileList.get(i).getSize()));
}
return mJsonArray;
}
..........hibernate Template class.......
private static final String SQL_GET_FILE_LIST = "select new FileObject(filename, size, id, type) from FileObject";
#Override
public List<FileObject> getFileList(String type) {
// TODO Auto-generated method stub
List<FileObject> files = hbTemplate.find(SQL_GET_FILE_LIST);
//hbTemplate.flush();
return files;
}
..........
Finally here is a print screen of what i originaly put inside my table but dissapears on its own:

i have fixed the problem
i changed <prop key="hibernate.hbm2ddl.auto">create</prop>
to <prop key="hibernate.hbm2ddl.auto">update</prop> and it worked
Are you creating/destroying the SessionFactory between calls? Could you have the hbm2ddl.auto property set to create-drop?
Actually, can you show the Hibernate settings?
Reference
Hibernate Core Reference Guide
Table 3.7. Miscellaneous Properties
In my case also table was getting deleted automatically, following solution worked for me:
org.hibernate.dialect.MySQL8Dialect
Appending the version number with the MySQL Dialect.
Because commit was not getting executed earlier with org.hibernate.dialect.MySQLDialect.
