I have a controller class, I'm expecting it to display the .xml response of model class which is annotated with #XmlRootElement. The Controller class method which displays all the student list is ,
#RequestMapping("studentlist")
public #ResponseBody
StudentList getStudentList() {
List<student> studentList = new ArrayList<student>();
studentList.add(new Student(3, "Robert", "Parera", "robert#gmail.com", "88"));
studentList.add(new Student(93, "Andrew", "Strauss","andrew#gmail.com", "89"));
studentList.add(new Student(239, "Eddy", "Knight", "knight#gmail.com", "79"));
return new StudentList(studentList);
}
}
i have added the #ResponseBody ,but still the class is not displaying the .xml response This is my web.xml.

Please advice what is missing. I also have model class which is properly annotated with #XMLElement ,#XmlRootElement etc. Kindly advice as I'm new to Spring MVC.

I know there are so many similar posts for this question. I tried to implement all but not working for me. Please help me why I am getting this error java.lang.AssertionError: Status expected:<200> but was:<404>

Do I need to include headers also to get that working? Please let me know

Even though you Enable WebMvc, you need to scan your controller to auto register controller & url mappings.component-scan scans packages to find and register beans within the application context.
<context:component-scan base-package="com.mycompany.xyz" />
I doubt component scanning is missing in your context xml.If so Add this statement in your beanRefContext.xml.
I have taken 2 PathVariable, and instead of taking these separately i want to store these 2 PathVariables in to a Map and want to retrieve it from the Map.
In Spring MVC 3.1.0 here is the my Controller class method:
#Controller
#RequestMapping("/welcome")
public class HelloController {
#RequestMapping(value="/{countryName}/{userName}",method=RequestMethod.GET)
public String getPathVar(#PathVariable Map<String, String> pathVars, Model model) {
String name = pathVars.get("userName");
String country = pathVars.get("countryName");
model.addAttribute("msg", "Welcome " + name+ " to Spring MVC & You are from" + country);
return "home";
}
My Request URL is :
http://localhost:3030/spring_mvc_demo/welcome/India/ashrumochan123
But when giving request using this url, i am getting HTTP Status 400 -
Description: The request sent by the client was syntactically incorrect.
When i am taking these Path Variables separately then it is working fine.
Here is the code -
#RequestMapping(value="/{countryName}/{userName}", method=RequestMethod.GET)
public String goHome(#PathVariable("countryName") String countryName,
#PathVariable("userName") String userName, Model model) {
model.addAttribute("msg", "Welcome " + userName
+ " to Spring MVC& You are from " + countryName);
return "home";
}
Please tell me whether i am doing anything wrong?
Any help would be greatly appreciated.
According to the Spring documentation, it's been there since version 3.2.
For the #PathVariable with Map<String,String>, I think you are missing <mvc:annotation-driven/> on your Spring servlet configuration:

ApplicationContext context = new FileSystemXmlApplicationContext(SalesManager.getSalesSourceFile());
SaleRoom saleRoom;

List<SaleRoom> allSales = new LinkedList<SaleRoom>();
// Get all sales id's for beans

salesNames.add(((Element) nNode).getAttribute("id").toString());
}
for (String saleName : salesNames) {

Exception in thread "main" java.lang.ClassCastException: $Proxy11 cannot be cast to application.common.entities.SaleRoom
The line that throws the exception:
saleRoom = (SaleRoom) context.getBean(saleName);
Any help will be appreciated. Thanks.
Does your SaleRoom class implement some interface? If yes, then you should use interface and not class in you code:
ISaleRoom saleRoom = (ISaleRoom) context.getBean(saleName);
Because if your bean implements some interface then Spring by default will create proxy based on this interface.
Here is a good article about proxy creation in Spring.
Also you can change proxying mechanism for Spring AOP if you want to create proxy for target class. This is described here in reference documentation.

In Email client class i am injecting property values like this
#Component
public class EmailClient {
#Value("${tutor.mail.common.note}")
private static String NOTE;
#Value("${tutor.mail.common.regards}")
private static String REGARDS;
#Value("${tutor.mail.from}")
private static String FROM;
#Autowired
private MailSender mailSender;
#Autowired
private Environment env;
public void sendRegisterMail(User user){
SimpleMailMessage message = new SimpleMailMessage();
message.setTo(user.getEmailID());
String subject = env.getProperty("tutor.register.success.mail.subject"); //retuns null
String contentTemplate = env.getProperty("tutor.register.success.mail.content"); //returns null
MessageFormat format = new MessageFormat(contentTemplate);
Object[] args = {user.getFullName()};
StringBuffer content = new StringBuffer();
content.append(format.format(args));
content.append(NOTE);
content.append(REGARDS);
message.setSubject(subject);
message.setText(content.toString());
mailSender.send(message);
}
}
Now problem is #Value("${property.key}") does work like charm when i inject a private field of the class like NOTE, REGARDS, FROM.
But if i need this value inside the method sendRegisterMail()
#Value("$key") is giving compiler error. I searched on web few examples are there getting properties value through environment so i used like i have done in EmailClient class but it always give me null. I checked the log it says it can not find the property key.
Can some body give me a clue how to inject properties value inside a method.
Thanks in advance
Try
#Value("#{propertyConfigurer['tutor.mail.common.note']}")
private static String NOTE;
For more info have a look at How can I inject a property value into a Spring Bean which was configured using annotations?
I'm trying to implement RedirectAttributes feature in Spring MVC 3.1-Release
I'm sending simple form to Post URL and would like to see the the value I'm sending in redirect:
my Controller looks like this:
#Controller
public class DefaultController {
#RequestMapping(value="/index.html", method=RequestMethod.GET)
public ModelAndView indexView(){
ModelAndView mv = new ModelAndView("index");
return mv;
}
#RequestMapping(value="/greetings.action", method=RequestMethod.POST)
public ModelAndView startTask(#RequestParam("firstName") String firstName,RedirectAttributes redirectAttributes){
redirectAttributes.addFlashAttribute("redirectAttributes.firstName", firstName);
ModelAndView mv = new ModelAndView(new RedirectView("success.html"));
return mv;
}
#RequestMapping(value="/success.html", method=RequestMethod.GET)
public ModelAndView successView(){
ModelAndView mv = new ModelAndView("success");
return mv;
}
}
Now my Servlet XML looks like this:

</bean>
</beans>
My problem is that in success.html view redirectAttributes is empty.
<body>
<h5>${redirectAttributes.firstName} </h5>
</body>
Prints nothing.
It does not work because You are using ModelAndView as a return value.
See JIRA Issue: https://jira.springsource.org/browse/SPR-8968
It looks like you need to remove "redirectAttributes." from the key name"
Instead of:
redirectAttributes.addFlashAttribute("redirectAttributes.firstName", firstName);
Do this:
redirectAttributes.addFlashAttribute("firstName", firstName);
