MVC not returning json... request not available - mysql

Question

Hi all I want to return a userName with a rest http request in Spring + Mysql.
Controller:
#Controller
#SessionAttributes("user")
public class UserController {
#Autowired
private UserService userService;
#RequestMapping(method=RequestMethod.GET, value="/userss/{userName}")
public #ResponseBody String getUserName(#PathVariable String userName) {
return userName;
}
}
Model:
#Entity
#Table(name="users")
public class User {
#Id
#GeneratedValue
private Long id;
#NotEmpty
#Size(min=4, max=20)
private String userName;
#NotEmpty
private String firstName;
#NotEmpty
private String lastName;
#NotEmpty
#Size(min=4, max=8)
private String password;
#NotEmpty
private String status;
#NotEmpty
#Email
private String emailAddress;
#NotNull
#Past
#DateTimeFormat(pattern="MM/dd/yyyy")
private Date dateOfBirth;
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
public String getFirstName() {
return firstName;
}
public void setFirstName(String firstName) {
this.firstName = firstName;
}
public String getLastName() {
return lastName;
}
public void setLastName(String lastName) {
this.lastName = lastName;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getStatus() {
return status;
}
public void setStatus(String status) {
this.status = status;
}
public String getEmailAddress() {
return emailAddress;
}
public void setEmailAddress(String emailAddress) {
this.emailAddress = emailAddress;
}
public Date getDateOfBirth() {
return dateOfBirth;
}
public void setDateOfBirth(Date dateOfBirth) {
this.dateOfBirth = dateOfBirth;
}
}
I just want to retrieve my services put,delete,post and get with requestmappings connecting with my model to my mysql DB. I´m trying to make the request in this way:
http://localhost:8080/portuzona/userss?userName=Arnoldo
But I get this:
HTTP Status 404 - /portuzona/userss
type Status report
message /portuzona/userss
description The requested resource is not available.
portuzona and userss is correctly handled (html views) but I cannot make a get in my controllers.
Log says correctly the Table has been found by the bean:
sep 25, 2015 2:07:22 PM org.hibernate.tool.hbm2ddl.TableMetadata <init>
INFO: HHH000261: Table found: portuzona.users
sep 25, 2015 2:07:22 PM org.hibernate.tool.hbm2ddl.TableMetadata <init>
INFO: HHH000037: Columns: [dateofbirth, password, firstname, emailaddress, id, username, lastname, status]
As a User requested here is more info that could be help .. or not:

Answer 1

Looks like you're mixing up mapping and path variables. Two options:
1:
#RequestMapping(method=RequestMethod.GET, value="/userss/{userName}")
public #ResponseBody String getUname(#PathVariable String userName) {
return userName;
}
http://localhost:8080/portuzona/userss/Arnoldo
2:
#RequestMapping(method=RequestMethod.GET, value="/userss/yourmapping")
public #ResponseBody String getUserName(#RequestParam String username) {
return username;
}
http://localhost:8080/portuzona/userss/yourmapping?username=Arnoldo

Answer 2

Try the following with http://localhost:8080/portuzona/userss?userName=Arnoldo
#RequestMapping(method=RequestMethod.GET, value="/userss")
public #ResponseBody String getUserName(#RequestParam String userName) {
return userName;
}
