Query manytomany
Hi,
I have a login where you have to enter username, password and role.
In the database username and password are stored in the same table and role in another one. The relation is manytomany.
If I had to check only username and password I wouldn't have any problem.
The problem comes up when I check the three of them together.
I'm not able to see if the role inserted by the user is correct because all the Query that I wrote failed.
What is the command and query that allow me to check the three parameters?
The role inserts by the user is saved into String role while username and password are stored into credentials(variable of Seam).
Below the user class and role class
User.java
package org.domain.docmanager.entity;
[...] import [...]
@Entity
@Name("user")
public class User implements Serializable {
private static final long serialVersionUID = 1L;
private Long id;
private String firstName;
private String lastName;
private String username;
private String password;
private Set<Role> roles= new HashSet<Role>(0);
private Set<Workflow> workflow = new HashSet<Workflow>(0);
public User() {
}
@Id
@GeneratedValue
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
@UserPrincipal
@NotNull
@Pattern(regex = "^\\w*$")
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
@UserPassword(hash = "none")
@NotNull
@Length(min = 5, max = 15)
@Column(length = 255)
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
@UserRoles
@ManyToMany(targetEntity = Role.class)
@JoinTable(name = "UserRole", joinColumns = @JoinColumn(name = "id"), inverseJoinColumns = @JoinColumn(name = "roleId"))
@DataModel
public Set<Role> getRoles() {
return roles;
}
@Transient
public List<Role> getRolesList() {
return new ArrayList<Role>(roles);
}
public void setRoles(Set<Role> roles) {
this.roles = roles;
}
@UserFirstName
public String getFirstName() {
return firstName;
}
public void setFirstName(String firstName) {
this.firstName = firstName;
}
@UserLastName
public String getLastName() {
return lastName;
}
public void setLastName(String lastName) {
this.lastName = lastName;
}
@OneToMany(mappedBy="user")
public Set<Workflow> getWorkflow() {
return workflow;
}
public void setWorkflow(Set<Workflow> workflow) {
this.workflow = workflow;
}
}Role.java
package org.domain.docmanager.entity;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import org.jboss.seam.annotations.security.management.RoleName;
@Entity
public class Role {
private Integer roleId;
private String rolename;
@Id
@GeneratedValue
public Integer getRoleId() {
return roleId;
}
public void setRoleId(Integer roleId) {
this.roleId = roleId;
}
@RoleName
public String getRolename() {
return rolename;
}
public void setRolename(String rolename) {
this.rolename = rolename;
}
}
