I was trying to understand the working of HibernateTemplate in Spring-hibernate environment. Since I am new to HibernateTemplate, I feel difficult to understand the errors. In my project I have used all the jar files availabe in spring-framework-4.0.3 and hibernate-4.3.5. Some of the additional jars used in this project are:
*cglib-nodep-2.1.3.jar
*commons-logging.jar
*ojdbc14.jar
*tomcat-dbcp-7.0.30.jar
Following java/xml files were used :
StudentDaoInterface.java
package dao;
import java.util.List;
import model.Student;
public interface StudentDaoInterface {
public int save(Student st);
public boolean update(Student st);
public boolean delete(Student st);
public Student findbyPK(int pk);
public List<Student> findAllUsingHQL();
public List<Student> findAllUsingCriteria();
}
StudentDaoImplHT.java
package dao;
import java.util.List;
import org.hibernate.criterion.DetachedCriteria;
import org.springframework.orm.hibernate4.HibernateTemplate;
import model.Student;
public class StudentDaoImplHT implements StudentDaoInterface {
private HibernateTemplate ht;
public void setHt(HibernateTemplate ht) {
this.ht = ht;
}
#Override
public int save(Student st) {
int i=(Integer)ht.save(st);
return i;
}
#Override
public boolean update(Student st) {
ht.update(st);
return true;
}
#Override
public boolean delete(Student st) {
ht.delete(st);
return true;
}
#Override
public Student findbyPK(int pk) {
Student st = (Student)ht.get(Student.class,pk);
return st;
}
#Override
public List<Student> findAllUsingHQL() {
List list = ht.find("from student");
return list;
}
#Override
public List<Student> findAllUsingCriteria() {
DetachedCriteria dc = DetachedCriteria.forClass(Student.class);
List list = ht.findByCriteria(dc);
return list;
}
}
Student.java
package model;
import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.Table;
#Entity

You should use org.springframework.orm.hibernate4.LocalSessionFactoryBean instead of org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean. But in doc, it says that the following, so be careful about your Spring version or decrease your Hibernate from 4.3.5. to 4.2 or 4.1 as documentation suggests.
This variant of LocalSessionFactoryBean requires Hibernate 4.0 or higher. Note that this version is not compatible with the (the quite refactored) Hibernate 4.3 yet; please upgrade to the Spring 4.0 line for full Hibernate 4.3 support. We recommend using this version with the latest Hibernate 4.1.x or 4.2.x releases.

can anyone help me to getting out from this errors/exceptions.
Thanks in advance.
I am not exactly sure whether this solution will work just a small hunch.
Replace :
Resource r = new ClassPathResource("applicationContext.xml");
BeanFactory factory = new XmlBeanFactory(r);
EmployeeDao dao = (EmployeeDao)factory.getBean("d");
with :
ApplicationContext r = new ClassPathXMLContext("applicationContext.xml);
Employee dao = r.getBean("d");
Hello i am using constructor injection in my spring demo app when i run this program i got :
java.lang.IllegalArgumentException exception
Anyone have solution where i am wong and whenever i run same program using setter injection it runs perfectly .
Here is my EmployeeBean.java
package cris;
public class Employee {
private int id;
private String name;
public Employee() { }
public Employee(int id,String name) {
this.id=id;
this.name=name;
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
void show() {
System.out.println(id+" "+name);
}
}
Here is my Address Bean using setter injection
package cris;
public class Address {
private String city,state,country;
public String getCity() {
return city;
}
public void setCity(String city) {
this.city = city;
}
public String getState() {
return state;
}
public void setState(String state) {
this.state = state;
}
public String getCountry() {
return country;
}
public void setCountry(String country) {
this.country = country;
}
public String toString()
{
return city+" "+state+" "+country;
}
}
Here is my spring.xml ie spring config file
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN 2.0//EN" "http://www.springframework.org/dtd/spring-beans-2.0.dtd">

<bean id="e" class="cris.Employee">
<constructor-arg type="int" value="12"></constructor-arg>
<constructor-arg type="String" value="anil"></constructor-arg>

And here is my Application Main Method
package cris;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class Test {
public static void main(String[] args) {
ApplicationContext context=new ClassPathXmlApplicationContext("cris/spring.xml");
Employee emp = (Employee)context.getBean("e");
emp.show();
}
}
kindly provide me suggestion where i am wrong so i will catch the exception thanks

When filling POJO's, (for what I know) Spring calls the no-arg constructor by default. If you decide to write a cTor with parameters yourself, you will not get a default cTor generated and you'll have to add a no-arg cTor for spring yourself.
public Employee() { }
Add type to your constructor-arg
<constructor-arg type="int" value="12" />
and
<constructor-arg type="java.lang.String" value="anil" />
EDIT
or you can use indexes
<constructor-arg index="0" value="12" />
and
<constructor-arg index="1" value="anil" />
Have spring.xml like this:
<?xml version = "1.0" encoding = "UTF-8"?>
<beans xmlns = "http://www.springframework.org/schema/beans"
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">
<bean id="a1" class="cris.Address">
<property name="city" value="Tikamgarh"></property>
<property name="state" value="Mp"></property>
<property name="country" value="India"></property>
</bean>
<bean id="e" class="cris.Employee">
<constructor-arg type="int" value="12"></constructor-arg>
<constructor-arg type="String" value="anil"></constructor-arg>
</bean>
</beans>
EDIT
My example:
spring.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"

I had the same issue and can't figure out why until I read each comment in current post and found out...
Using Spring 3.* and Java 11 that is a compatibility issue. When I downloaded the latest version (Spring 5.*) and set to the CLASSPATH. Then everything works.
I am new to spring. I was trying to integrate spring with hibernate but
I am not able to get my entity class Employee using packagesToScan, before this I tried annnotatedClasses as well that too didn't work, I also tried wildcards (com.sfb.**.*) with packagesToScan but no luck yet. FYI I am using javax.persistence.Entity so not an import issue too. Below are my spring.xml file and other along with stacktrace:

Here is an error (Employee.java):
#OneToOne(fetch = FetchType.LAZY, mappedBy = "address", cascade =
CascadeType.ALL)
private Address address;
mappedBy attribute should only used for inverse size of association, so it is not applicable here.
I guess you are trying to build simple unidirectional association.
It should look something like:
#OneToOne(fetch = FetchType.LAZY, cascade = CascadeType.ALL)
#JoinColumn(name="ADDRESS_ID") /* this is the name of address id column in 'emp' table*/
private Address address;
Here is almost identical example from book.
I am getting below exception:

I have tried to link through JDBC and it's working fine.
salary field has int type, but there is double in the hibernate mapping
This might be caused because the hibernate trying retrieving the dtd file. so, the workaround could be :
change the value of the dtd from that to "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd"
Create your own function to parse the configuration then passed to the hibernate like this
public static Document parseConfiguration(String resourcePath) throws Exception {
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
factory.setValidating(false); <-- the magic is here
DocumentBuilder builder = factory.newDocumentBuilder();
return builder.parse(builder.getClass().getResourceAsStream(resourcePath));
}
I am not getting the error you are getting, though I fixed lot of errors in your entity (properties defined in the mapping file not present in the entity). I have reached the step where it is trying to insert the record, so I am well past the stage where you are getting the error.
By looking into the hibernate source file (org.hibernate.cfg.Configuration.addInputStream(Configuration.java:499)) which is throwing error, hibernate is not able to reach your mapping xml file.
Please double check if the mapping file is at proper location and also readable.
Also make sure you have correct version of hibernate jar in the classpath.
I have a simple spring jdbc program but when I run the program I get a queryTimeOut exception.

The error points out that you're missing a class from your classpath. It doesn't mean that specific exception would get thrown during that particular invocation; but it simply doesn't find the class for it.
To add the QueryTimeoutException class in your classpath, you need to add a dependency on the spring-tx module.
You can add this dependency
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-tx</artifactId>
<version>${spring.version}</version>
</dependency>
If your are using maven or this one
[group: 'org.springframework', name: 'spring-tx', version: '4.1.6.RELEASE'],
if you are using gradle.
JdbcTemplate has queryTimeout property, you can try to configure it to a desired value.
