#Query Spring Data JPA Update Not Working - sql

Question

Here is my User entity:
#Entity
#Table(name="users")
public class User implements IBaseEntity<User> {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
#Column(name = "id")
private Long userId;
#Column(unique = true)
#NotNull
private String username;
#Column(unique = true)
#NotNull
private String email;
#Column
#NotNull
private String password;
// #formatter:off
#ManyToMany(cascade = CascadeType.ALL)
#JoinTable(name = "users_roles",
joinColumns = { #JoinColumn(name = "user_id") },
inverseJoinColumns = { #JoinColumn(name = "role_id") })
// #formatter:on
private List<Role> roles = new ArrayList<Role>();
#Column
#NotNull
private Boolean locked;
...
}
Here is my Role entity:
#Entity
#Table(name="roles")
public class Role implements IBaseEntity<Role> {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
#Column(name = "id")
private Long roleId;
#Column(unique = true)
#NotNull
private String name;
...
}
Here is my User service:
package org.quickloanconnect.service;
public interface IUsersService extends IBaseService<User>{
public void updateUserRolesById(List<Role> roles, Long userId);
...
}
Here is the UserServiceImpl :
#Service
#Transactional
public class UsersServiceImpl extends AbstractServiceImpl<User> implements
IUsersService {
...
#Override
#Transactional
public void updateUserRolesById(List<Role> roles, Long user_id) {
userDao.updateUserRolesById(roles, user_id);
}
...
}
And here is the dao:
public interface IUsersDao {
...
#Modifying
#Query("UPDATE User u SET u.roles = :roles WHERE u.userId = :userId")
public void updateUserRolesById(#Param("roles") List<Role> roles,
#Param("userId") Long userId);
...
}
When I run this update, I get the following: SqlExceptionHelper : No value specified for parameter 2 . What is causing this? When I update my user with a single role, I see that a List of size one is getting to the dao with the correct userId (both parameters present), but the update seems to fail at the dao level with the "SqlExceptionHelper : No value specified for parameter 2" error message.
