I have searched the net and found few solution,but still i am facing the same problem.
I am trying to create a web application with Angularjs as frontend end spring rest as back end.
I am able to access the url resource through $http.post methos, but while the binding of data to pojo doesnt happen. The values are always null.

Angualrjs controller file
login.controller('RegisterController',['$scope','userFactory', function($scope, userFactory) {
$scope.user;
$scope.saveUser = function(){
userFactory.saveUser($scope.user);
};
}]);
Angularjs factory js file
angular.module('login')
.factory('userFactory' , ['$http', function($http){
var userFactory= {};
userFactory.authenticate = function(user){
console.log(user.name);
console.log(user.password);

Jsp page invokes userFactory.saveUser() function which in turns call my rest service,
my controller class
#Controller
public class UserController {
#RequestMapping(value = "/authenticate", method = RequestMethod.GET)
public #ResponseBody String getState(UserData ud) {
System.out.println(ud.getPassword());
return "true";
}
#RequestMapping(value = "/register", method = RequestMethod.POST)
public #ResponseBody String registerUser(Users ud) {
System.out.println(ud.getPassword());
return "true";
}
}
The println statements always prints null.
Can anyone tell me where i am going wrong.
You need the #RequestBody in your getState and registerUser methods before the Argument. Furthermore getState must be a POST Method.
#Controller
public class UserController {
#RequestMapping(value = "/authenticate", method = RequestMethod.POST)
public #ResponseBody String getState(#RequestBody UserData ud) {
System.out.println(ud.getPassword());
return "true";
}
#RequestMapping(value = "/register", method = RequestMethod.POST)
public #ResponseBody String registerUser(#RequestBody Users ud) {
System.out.println(ud.getPassword());
return "true";
}
}

I believe you configure the basePackage in MapperScannerConfigurer incorrectly. It should be package that containing the mapper class rather than the mapper class itself. So try to change the basePackage to:
<bean id="mapperSpeaker" class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="ph.com.aub.mapper" />
<property name="sqlSessionFactoryBeanName" value="sqlSessionFactorySpeaker" />

I am trying to implement spring rest method with post type. I am trying to retrieve JSON and convert it into java object. And returning with JSON only. Here is my code

#RequestMapping(value = "/post/create", method = RequestMethod.POST,consumes=MediaType.APPLICATION_JSON)
public #ResponseBody ResponseEntity<String> authenticateMobUser(#RequestBody User objUser) {
String result = null;
result = createUser(objeUser);
return new ResponseEntity<String>(result, HttpStatus.OK);
}
private String createUser(User objUser) {
// My create user code here
return "{\"status\":\"SUCCESS\",\"message\":\"SUCCESS\"}";
}

String id;

Finally here is rest client I am using to call service
Client client = Client.create();
String strURL = null;
String domainName = "http://localhost:8080";
strURL = domainName + "/UserManagement/user/post/create";
String input = "{\"id\":\"12345\",\"name\":\"navnath\"}";
WebResource webResource = client.resource(strURL);
ClientResponse response = webResource.accept(MediaType.APPLICATION_JSON).type(MediaType.APPLICATION_JSON).post(ClientResponse.class, input);
if (response.getStatus() != 200) {
throw new RuntimeException("Failed : HTTP error code : "
+ response.getStatus());
}
When I run this code, I received "415 unsupported media type". while sending and retrieving, I am using MediaType.APPLICATION_JSON still getting this error.
Surly I am doing something wrong here but what it is, not getting
Don't you have to use MediaType.APPLICATION_JSON_VALUE in your RequestMapping?
Also, try to use RestTemplate instead of client if it is possible.
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_JSON);
String input = "{\"id\":\"12345\",\"name\":\"navnath\"}";
HttpEntity<String> entity = new HttpEntity<>(input, headers);
ResponseEntity<String> responseEntity = restTemplate.postForEntity("/user/post/create", entity, String.class);
if (responseEntity.getStatusCode().value() != 200) {
throw new RuntimeException("Failed : HTTP error code : "
+ responseEntity.getStatusCode().getReasonPhrase());
}
P.S. To solve the issue replace your AnnotationMethodHandlerAdapter in spring config with .
I am creating a spring web application with help of hibernate. I have created spring-dipatcher-servlet.xml for all the configuration. I want to access the database using hibernate without creating the hibernate.cfg.xml file as I am using spring. I am getting Null Pointer Exception while accessing the Session Factory in DAO.

How can I resolve my issue, what I am doing wrong?
Thanks in advance. Your help is appreciated.
here the problem is currently your dispatcher servlet does not know how to create and set the bean SessionFactory from. (As you see, your setSessionFactory is in UserDao class )
you may need to declare UserDao bean in spring-dispatcher-servlet.xml.
for eg:
<bean id="userDAO" class="your.package.nameforUserDao">
<property name="sessionFactory" ref="sessionFactory" />
</bean>

Why does Spring MVC respond with a 404 and report "No mapping found for HTTP request with URI [...] in DispatcherServlet"?

Closed 6 years ago.
I´m getting a mapping error on my application, any help would be greatly appreciated! =)
Error message: No mapping found for HTTP request with URI [/springapp/priceincrease.htm] in DispatcherServlet with name 'springapp'
You can find some code below:

You forgot to add handler mapping in your application context:
<bean id="handlerMapping" class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping"/>
There problem in your GET method : formBackingObject.
Depends upon your requirement it should return to view or make it REST method.
Case 1 : return to view (JSP,HTML,XSLT...)
#RequestMapping(value="/priceincrease.htm",method = RequestMethod.GET)
protected String formBackingObject(HttpServletRequest request,Model model) throws ServletException {
PriceIncrease priceIncrease = new PriceIncrease();
priceIncrease.setPercentage(15);
model.addAttribute("priceIncrease",priceIncrease);
return "view_name";
}
Case 2 : REST method using #ResponseBody (jackson.core Jar is necessary)
#RequestMapping(value="/priceincrease.htm",method = RequestMethod.GET)
#ResponseBody
protected PriceIncrease formBackingObject(HttpServletRequest request) throws ServletException {
PriceIncrease priceIncrease = new PriceIncrease();
priceIncrease.setPercentage(15);
return priceIncrease;
}
Here you have modify controller's parent mapping (simply remove it) for both cases
#Controller
public class PriceIncreaseFormController {
}

SOLVED
Lately I've been having problems with an Spring MVC application which I'm trying to develop.
The main problem is that I don't know exactly why the #Autowired annotation is not working properly and that's probably because I have something wrong. I'm going to post here my code so you can help me with my issue! Thanks a lot guys:

}
In this point when I try to login to the application and I'm gonna check the Dao to access to the database I'm getting the 'securityDao' property null. Exactly in CustomUserDetailsService in the following line : com.agrichem.server.model.security.User user = securityDAO.getUser(new com.agrichem.server.model.security.User(arg0, "")); and obvisously I'm getting a NullPointerException.

Solution:
Found it! The problem was that in WebSecurityConfig I was doing the following:
#Autowired
public void configureGlobal(AuthenticationManagerBuilder auth)
throws Exception {
auth.userDetailsService(**new CustomUserDetailsService()**);
}
and then the new instance of CustemUserDetailsService was out of the Spring Control.
To solve it I added in CustomUserDetailsService a constructor:
private SecurityDao securityDAO;
public CustomUserDetailsService(SecurityDao securityDAO) {
super();
this.securityDAO = securityDAO;
}
and I modified WebSecurityConfig in this way:
#Autowired
private SecurityDao securityDao;
#Autowired
public void configureGlobal(AuthenticationManagerBuilder auth)
throws Exception {
auth.userDetailsService(new CustomUserDetailsService(securityDao));
}
Thanks anyway for your help!
Eventhough you have solved this issue, the solution is ugly in terms of Spring Dependency Injection and Inversion of Control theories.
Basically you should never use the new keyword to instantiate objects if you are using Spring. Because all objects must be instantiated and injected only by the Spring Container.

WebSecurityConfig.java
#Configuration
#EnableWebMvcSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
#Autowired
private UserDetailsService customUserDetailsService
#Autowired
public void configureGlobal(AuthenticationManagerBuilder auth)
throws Exception {
auth.userDetailsService(customUserDetailsService);
}
#Override
protected void configure(HttpSecurity http) throws Exception {

}
}
And you should have a Default Constructor for CustomUserDetailsService which doesn't take in any arguments. All your #Autowired properties should be inject by the spring container.
Furthermore you are intermixing Spring Java Configuration and Spring XML Configuration which is fine, but it is better if you decide on one particular method to define your beans.
