Spring mvc can not get the form param

Spring mvc can not get the form param - java

Below is my code, and always get null for query method, i do not know why this happen. I can get the form param by other ways, such as #RequestParam etc. Do i need to set configuration for the Phone Class in the XML file? if so, how can i configure Phone Class in XML? My XML is recharge-servlet.xml.
Below is the Controller:
package com.nu.template.recharge;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.ModelAndView;
#Controller
#RequestMapping("/mobile")
public class XJMobile {
#RequestMapping(value = "/index", method = RequestMethod.GET)
public ModelAndView getIndexPage() {
ModelAndView mav = new ModelAndView("recharge");
return mav;
}
#RequestMapping(value = "/query", method = RequestMethod.POST)
public String query(Phone phone) {
System.out.println(phone.getNumber());
return "helloworld";
}
}
Form:
<form action="query" method="POST" name="phone_form">
<section>
<label>phone:</label>
<input type="text" name="phone_number" />
</section>
<input type="submit" value="submit">
</form>
Phone Class:
package com.nu.template.recharge;
public class Phone {
private String phone_number;
public String getNumber() {
return this.phone_number;
}
public void setNumber(String phone_number) {
this.phone_number = phone_number;
}
}
recharge-servlet.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:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd
http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd">
<mvc:annotation-driven />
<context:component-scan base-package="com.nu.template.recharge"/>
<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/view/"/>
<property name="suffix" value=".jsp"/>
</bean>

You can get your Phone object initialized by
#RequestMapping(value = "query", method = RequestMethod.POST)
public String query(#RequestParam("phone_number") Phone phone) {
System.out.println(phone.getNumber());
return "helloworld";
}
Spring generally looks for same parameter type for binding or you can tell it to bind with your pojo, given a setter method which accepts parameter type.

Autowired Annotation not working when uisng <context:annotation-config /> in ApplicationContext.xml

<context:annotation-config />
when above line is added in ApplicationContext.xml file the Test.java is not running but when i add this it works but in the tutorial i was going through it says both the methods work can someone help whats the problem with
above line of code.
<bean class="org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor"/>
Employee.java
package com.stp.beans;
import org.springframework.beans.factory.annotation.Autowired;
public class Employee {
private Address empaddress;
public Address getEmpaddress() {
return empaddress;
}
#Autowired
public void setEmpaddress(Address empaddress) {
this.empaddress = empaddress;
}
}
Address.java
package com.stp.beans;
public class Address {
private String address;
public String getAddress() {
return address;
}
public void setAddress(String address) {
this.address = address;
}
}
ApplicationContext.xml

Test.java
package com.stp.test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import com.stp.beans.Employee;
public class Test {
public static void main(String[] args) {
ApplicationContext context = new ClassPathXmlApplicationContext("/com/stp/cfgs/ApplicationContext.xml");
Employee emp = (Employee) context.getBean("empbean");
System.out.println(emp.getEmpaddress());
}
}

When you use <context:annotation-config />, your ApplicationContext.xml should be like below.
<?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"

http://www.springframework.org/schema/beans/spring-beans-4.3.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-4.3.xsd">
<context:annotation-config />
<bean id ="empbean" class="com.stp.beans.Employee"></bean>
<bean id ="adrbean" class="com.stp.beans.Address"></bean>
</beans>
You had just missed the context related definitions.

Hibernate validator doesn't work

I'm using Hibernate validator with Hibernate and Spring, but it seems that validations don't work. When I don't enter a String or enter a String of 1 character (which is not between min=4 and max=20) is not showing any error and therefore saves in the table. What am I missing?

Finally I found the error ,
the problem was that I didin't add hibernate-validator jar I only added files in the dist/lib/required :
classmate-1.3.1
javax.el-2.2.4
-javax.el-api-2.2.2
jboss-logging-3.3.0.Final
validation-api-1.1.0
So if that happens to someone just add : hibernate-validator-5.3.2.Final.

After spent one hour to study two validation tutorials:
Hibernate Validator Annotations Example
Spring MVC Form Validation Annotation Example
I suggest you some solutions.
1) Verify hibernate validation annotation working or not
ValidatorFactory factory = Validation.buildDefaultValidatorFactory();
Validator validator = factory.getValidator();
Set<ConstraintViolation<Etudiant>> constraintViolations = validator.validate(etudiant);
2) You can create custom validator, for example EtudiantValidator, then validate manually like below:
#RequestMapping(value="save",method=RequestMethod.POST)
public String saveetudient(Model md,#ModelAttribute("etudiant") Etudiant etudiant, BindingResult res){
new EtudiantValidator().validate(etudiant, result);
...
}
However I deep into your code,I see that you have a mistake on this method:
#RequestMapping(value="save",method=RequestMethod.POST)
public String saveetudient(Model md,
#Valid #ModelAttribute("etudiant") Etudiant et,
BindingResult res)
Should change it to like below
#RequestMapping(value="save",method=RequestMethod.POST)
public String saveetudient(Model md,
#Valid #ModelAttribute("etudiant") Etudiant etudiant,
BindingResult res)
Hope this help!

Spring MVC Simple controller example

Can you please help me figure out how to invoke the login page by using my controller?
Here is my code:

public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getPassword() {

}
public void setPassword(String password) {
this.password = password;
}
}

You are missing #Controller annotation on your controller class. Spring does not create a handler for url unless you instantiate a controller by using annotation.

It does the same as in your code,when you hit url with localhost:8080/Mvc_Demo/login it must show your login.jsp,
hope this solves your problem.
package com.mvc.demo;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.ModelAndView;
public class MvcDemo {
#RequestMapping(value="/login", method = RequestMethod.GET)
public String showForm( )
{
ModelAndView mv = new ModelAndView("login");
return mv;
}
}

Try this code:
package com.mvc.demo;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
#Controller
public class MvcDemo {
// To call the view for login
#RequestMapping(value = "/login", method = RequestMethod.GET)
public ModelAndView login() {
return new ModelAndView("login","newEmp", new Emp());
}
// To call the validate login after submit
#RequestMapping(value = "/user-login", method = RequestMethod.POST)
#ResponseBody
public ModelAndView userLogin(Emp emp) {
//TODO check 'emp' object to validate user
return new ModelAndView("home");
}
}

Persisting to MySQL using Spring Framework, Hibernate and JPA failed, not really persisting to the database

I was reading all the posts on this issue, but none of them helped.
I am trying to persist my entity to MySQL using Hibernate, JPA on Spring Framework 3.0.1. I can find rows from database and display, to do that when the form displayed the textbox holds fields fron the database, but when I try to save to the database, it doesn't change any row at all.
My configuration looks like below ...
