我想检索所有具有特定角色的用户,例如“ROLE_USER”。
下面是用户、角色和用户角色的域类。
用户.groovy
class User {
transient springSecurityService
String username
String password
String email
boolean enabled
boolean accountExpired
boolean accountLocked
boolean passwordExpired
static constraints = {
username blank: false, unique: true
password blank: false
}
static mapping = {
password column: '`password`'
}
Set<Role> getAuthorities() {
UserRole.findAllByUser(this).collect { it.role } as Set
}
def beforeInsert() {
encodePassword()
}
def beforeUpdate() {
if (isDirty('password')) {
encodePassword()
}
}
protected void encodePassword() {
password = springSecurityService.encodePassword(password)
}
}
角色.groovy
class Role {
String authority
static mapping = {
cache true
}
static constraints = {
authority blank: false, unique: true
}
}
用户角色.groovy
class UserRole implements Serializable {
User user
Role role
boolean equals(other) {
if (!(other instanceof UserRole)) {
return false
}
other.user?.id == user?.id &&
other.role?.id == role?.id
}
int hashCode() {
def builder = new HashCodeBuilder()
if (user) builder.append(user.id)
if (role) builder.append(role.id)
builder.toHashCode()
}
static UserRole get(long userId, long roleId) {
find 'from UserRole where user.id=:userId and role.id=:roleId',
[userId: userId, roleId: roleId]
}
static UserRole create(User user, Role role, boolean flush = false) {
new UserRole(user: user, role: role).save(flush: flush, insert: true)
}
static boolean remove(User user, Role role, boolean flush = false) {
UserRole instance = UserRole.findByUserAndRole(user, role)
if (!instance) {
return false
}
instance.delete(flush: flush)
true
}
static void removeAll(User user) {
executeUpdate 'DELETE FROM UserRole WHERE user=:user', [user: user]
}
static void removeAll(Role role) {
executeUpdate 'DELETE FROM UserRole WHERE role=:role', [role: role]
}
static mapping = {
id composite: ['role', 'user']
version false
}
}
这些域类是由Spring Security插件生成的。
我只为用户类添加了电子邮件字段。
这是我的UserController.groovy
class UserController {
def index = {
}
def list = {
def role = Role.findByAuthority("ROLE_USER")
println "role id "+role.id
def users = User.findAll() //Its giving me all Users regardless of Role
println "total users "+users.size()
for(user in users)
{
println "User "+user.username+" "+user.email
}
render (view: "listUsers", model:[users:users])
}
}
在我使用的列表操作中,User.findAll()
但它给了我所有角色的所有用户。
我只想要某个角色的用户列表..
编辑
将角色分配给新创建的用户的代码
def username = params.username
def emailID = params.emailID
def password = params.password
def testUser = new User(username: username, enabled: true, password: password,email:emailID)
testUser.save(flush: true)
def userRole = new Role(authority: 'ROLE_USER').save(flush: true)
UserRole.create testUser, userRole, true
谢谢..
