Bean Creation Exception: Could not resolve matching constructor while loading xml - java

I am trying to call mainframe stored procedure using TempStatusClass in this class I am loading status-dao.xml which has the datasource defined and stored procedure defined. When I try to call this I am getting following exception org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'testProcedure' defined in class path resource [status-dao.xml]: Could not resolve matching constructor (hint: specify index/type/name arguments for simple parameters to avoid type ambiguities).
Not sure what is causing this. Any help is highly appreciated.
#TempStatusClass
public class TempStatusClass implements DataServiceIF{
#Override
public Object execute(Object param) throws AppException {
StatusUpdateVO input = new StatusUpdateVO();
input.setShipment("X3328332842");
Map dataMap = null;
String springConfig = "status-dao.xml";
ApplicationContext context =new ClassPathXmlApplicationContext(springConfig);
StatusUpdateImpl statusUpdate = (StatusUpdateImpl) context.getBean("statusUpdateDao");
try {
dataMap = statusUpdate.getData(input);
} catch (StatusUpdateDAOException e) {
// TODO Auto-generated catch block

Are you using spring-data-commons RC1 version? I have the same problem and it started with version bump of this dependency. I created an issue on spring's jira as well:

XML to Spring Java annotation conversion

I have a sample code in which I am trying to convert application-context.xml to Spring annotated Java class. How to add constructor-arg with proper annotations here. Could you please help me sort this.
application-context.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:oxm="http://www.springframework.org/schema/oxm" xmlns:util="http://www.springframework.org/schema/util"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd

<context:component-scan base-package="myproject"/>
<!-- Define the SOAP version used by the WSDL -->
<bean id="soapMessageFactory" class="org.springframework.ws.soap.saaj.SaajSoapMessageFactory">
<property name="soapVersion">
<util:constant static-field="org.springframework.ws.soap.SoapVersion.SOAP_12"/>
</property>
</bean>
<!-- The location of the generated Java files -->
<oxm:jaxb2-marshaller id="marshaller" contextPath="myproject.wsdl.currency"/>
<!-- Configure Spring Web Services -->
<bean id="webServiceTemplate" class="org.springframework.ws.client.core.WebServiceTemplate">
<constructor-arg ref="soapMessageFactory"/>
<property name="marshaller" ref="marshaller"/>
<property name="unmarshaller" ref="marshaller"/>
<property name="defaultUri" value="http://www.webservicex.net/CurrencyConvertor.asmx?WSDL"/>
</bean>
<bean id="example" class="org.project.Example"/>
I have created Config.class as below.
#Configuration
public class AppConfig {
#Bean(name="soapMessageFactory")
public SaajSoapMessageFactory getSoapMsgFactory() {
SaajSoapMessageFactory soapFactory = new SaajSoapMessageFactory();
soapFactory.setSoapVersion(SoapVersion.11);
return soapFactory;
}
#Bean(name="webServiceTemplate")
public WebServiceTemplate getWsTemplate(Marshaller marshaller, Unmarshaller unmarshaller) {
WebServiceTemplate wsTemplate = new WebServiceTemplate();
//how to configure the constructor-arg here
wsTemplate.setMarshaller(marshaller);
wsTemplate.setUnMarshaller(unmarshaller);
wsTemplate.setDefaultUri(http://www.webservicex.net/CurrencyConvertor.asmx?WSDL);
return wsTemplate;
}
#Bean(name="example")
public Example getExample() {
return new ExampleImpl();
}
This should work...
#Bean(name="soapMessageFactory")
public SaajSoapMessageFactory getSoapMsgFactory() {
SaajSoapMessageFactory soapFactory = new SaajSoapMessageFactory();
soapFactory.setSoapVersion(SoapVersion.11);
return soapFactory;
}
#Bean(name="webServiceTemplate")
public WebServiceTemplate getWsTemplate(SaajSoapMessageFactory soapFactory, Marshaller marshaller, Unmarshaller unmarshaller) {
WebServiceTemplate wsTemplate = new WebServiceTemplate(soapFactory);
wsTemplate.setMarshaller(marshaller);
wsTemplate.setUnMarshaller(unmarshaller);
wsTemplate.setDefaultUri(http://www.webservicex.net/CurrencyConvertor.asmx?WSDL);
return wsTemplate;
}
When you specify any dependecy in #Bean method, spring will search for that bean in its context.
Since SaajSoapMessageFactory is locally created and doesn't have any other dependency, you could just call it locally like this
WebServiceTemplate wsTemplate = new WebServiceTemplate(getSoapMsgFactory());

Oracle nested table as input argument to stored procedure with Mybatis

I need to call an Oracle Stored Procedure that has an input argument with a nested table type, using Mybatis.
I cannot find any documentation or example concerning this particular usage of MyBatis.
Has anyone done this before, or seen an example?
Many thanks.
Let's take this example:
PROCEDURE PROCEDURERECORD
(P_VAL_REC IN Package.RECORD
,P_VAL_NUM IN VARCHAR2
,P_DAT_VAL OUT DATE
);
In your database redefine the SP:
PROCEDURE PROCEDURERECORD_NEW
(P_VAL_REC IN RECORD_TYPE (you create it in Types)
,P_VAL_NUM IN VARCHAR2
,P_DAT_VAL OUT DATE
);
you should reconfigure you SP bean with spring :
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:p="http://www.springframework.org/schema/p" xmlns:util="http://www.springframework.org/schema/util"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util.xsd">
<bean id="PROCEDURERECORD_NEW" parent="storedProcedure">
<constructor-arg index="0" value="PROCEDURERECORD" />
<constructor-arg index="1" value="false" />
<property name="params">
<list>
<bean parent="sqlRecordParamIn">
<constructor-arg index="0" value="P_VAL_REC" />
<constructor-arg index="2" value="RECORD_TYPE" />
</bean>
<bean parent="sqlNumericParamIn">
<constructor-arg value="P_VAL_NUM" />
</bean>
<bean parent="sqlDateParamOut">
<constructor-arg value="P_DAT_VAL"/>
</bean>
</list>
</property>
</bean>
In your implementation code, use SqlStructValue like this:
#Override
public DateTime getSpReturn(RecordClass record,Long valNum){
Map<String, Object> args = new HashMap<String, Object>();
args.put("P_VAL_REC", new SqlStructValue<RecordClass>(record,new RecordClassMapper()));
args.put("P_VAL_NUM", valNum);
Map<String, Object> result = procedureRecordNew.execute(args);
return (DateTime)result.get("P_DAT_VAL");
}
As for the mapper you create it like this:
#Component("RecordClassMapper")
public class RecordClassMapper implements StructMapper<RecordClass> {
#Override
public STRUCT toStruct(RecordClass source, Connection conn, String typeName) throws SQLException {
Object[] objectProperties = new Object[] { new source.getrecordatr1(), source.getrecordatr2(), source.getrecordatr3() };
return new STRUCT(new StructDescriptor(typeName, conn), conn, objectProperties);
}
#Override
public RecordClass fromStruct(STRUCT struct) throws SQLException {
// Auto-generated method stub
throw new UnsupportedOperationException("Not implemented");
}
}

Spring isn't resolving the appropriate constructor

Problem Description:
I am facing an exception while trying to run the below code. Don't even have a clue.

gen.load("classpath:simplespringconstinjection.xml");
gen.refresh();

Dependent d2 = (Dependent) gen.getBean("dependent2");
}
}
By changing this:
<bean id="dependent" class="com.learning.spring.constinjection.Dependent">
<constructor-arg ref="dependency" name="dpcy" />
<constructor-arg name="mesg" value="Hi this is a test mesg" />
</bean>
to this:
<bean id="dependent" class="com.learning.spring.constinjection.Dependent"
c:dpcy-ref="dependency" c:mesg="Hi, this is another test mesg" />
I was able to get the ApplicationContext to properly initialize with no errors.
See this Spring doc for information on the "c" namespace.
There is still an issue with the constructor with the #Autowired annotation.

SessionFactory not initialized

i created a DAO (ForecastPersistorDao.java) which is the interface and its corresponding implementation (ForecastPersistorDaoImpl.java). The implementation has a method 'persist()' whose job is to persist some data into the database. When I try to call persist to persist the data, it throws a NullPointerException since it does not initialize SessionFactory properly. Please help me point out what I might be doing wrong:
ForecastPersistorDao.java
public interface ForecastPersistorDao {
void persist(List<ForecastedDemand> forecastedDemands);
List<DemandForecast> retrieveLastForecast(String marketplaceId);
}
ForecastPersistorDaoImpl.java
#Repository("forecastPersistorDao")
public class ForecastPersistorDaoImpl implements ForecastPersistorDao {
private SessionFactory sessionFactory;
#Autowired
public void setSessionFactory(SessionFactory sessionFactory) {
this.sessionFactory = sessionFactory;
}
/**
* Persist forecast in the database for later
*
* #param forecastedDemands
* List of forecast for all asin:marketplaceId tuple
*/
#Transactional
#Override
public void persist(List<ForecastedDemand> forecastedDemands) {
System.out.println("THIS IS ALWAYS NULL-------->>>>>>>> " + sessionFactory);
Session session = sessionFactory.getCurrentSession();
Date forecastCalculationDate = new Date();
// For each [asin:marketplace] tuple
for (ForecastedDemand forecastedDemand : forecastedDemands) {
String asin = forecastedDemand.getAsinMarketplaceId().getAsin();
String marketplaceId = forecastedDemand.getAsinMarketplaceId().getMarketplaceId();
String forecastingModel = forecastedDemand.getForecastingModel();
SortedMap<Instant, Double> forecast = forecastedDemand.getForecast();
// for each forecast date - write an entry in demand_forecasts table
for (Map.Entry<Instant, Double> entry : forecast.entrySet()) {
Date dateOfForecast = entry.getKey().toDate();
double quantityForecasted = entry.getValue();
DemandForecast forecastToPersist = new DemandForecast(asin, marketplaceId, forecastCalculationDate,
forecastingModel, quantityForecasted, dateOfForecast);
session.save(forecastToPersist);
}
}
}
Main class (Runner.java):
public final class FbsRunner {
private ForecastPersistorDao forecastPersistorDao;
public static void main(String[] args) {
Runner runner = new Runner();
runner.run();
}
public void run() {
ApplicationContext context =
new FileSystemXmlApplicationContext("spring-configuration/application-config.xml");
forecastPersistorDao = (ForecastPersistorDao) context.getBean("forecastPersistorDao"); // this works fine
System.out.println(">>>>>>>>>> forecastPersistorDao [this is fine (not null)]: " + forecastPersistorDao);
List<ForecastedDemand> forecastedDemand = [a list of Forecasted demand to be persisted int he DB]
// THE CALL BELOW FAILS...
forecastPersistorDao.persist(forecastedDemands);
System.out.println("Persisted demand in the database"); // We don't reach here.
}

Please try to add <context:component-scan base-package="YOUR PACKAGE NAME" /> into your application-config.xml. This will tell Spring to scan for annotated components that will be auto-registered as Spring beans.
"YOUR PACKAGE NAME" should be the package name to scan for annotated components.
sessionFactory didn't autowired correctly ,add "#component" for ForecastPersistorDaoImpl and add "context:component-scan" in application-config.xml to tell spring to initialize.

Object retrieved from ioc turned null after JMX method invoker

I am using Spring 3.1 as standalone app.
I have some wierd situation and I guess I am missing something.
I have class which has method that I have exposed via JMX console.
that method is invoking a method via bean.
that bean I am initializing in advaned.
the wierd thing that after i am invoking the method via the jmx console the bean instance turn to be null.
Thats the JMX bean which is exposed:
public class TriggerBean implements IJmxTriggerBean
{
static Logger logger = Logger.getLogger(TriggerBean.class);
FeedListenerBean fe = null;
public void start()
{
try
{
// init();
PropertyConfigurator.configure(FixGWConstants.LOG4J_PATH);
ApplicationContext context = new ClassPathXmlApplicationContext(FixGWConstants.APPLICATION_CONTEXT_XML);
fe = (FeedListenerBean) context.getBean("FeedListenerBean");
doTheListen();
}
catch (Throwable t)
{
logger.error(t);
System.out.println(t);
}
}
//thats the method being exposed by jmx. pay attention that fe object has been initialized before by the start()
public void doTheListen()
{
fe.listen();
}
private void init()
{
Resource resource = new ClassPathResource(System.getProperty("user.dir") + "//config.properties");
try
{
Properties props = PropertiesLoaderUtils.loadProperties(resource);
String log4jPath = props.getProperty("LOG4J_PATH");
}
catch (IOException e)
{
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
I am testing it via standalone:
public static void main(String[] args) throws Exception
{
protected TriggerBean trigger = new Trigger();
trigger.start();
}

When I first using start() the object fe is doing great.
but after invoking doTheListen( via JMX the object fe remind null(although it has already been initialized before)
any idea?
thanks,
ray.
