注意：此处当用户并非单点登录，主要实现功能效果防止多端登录，一方登录，另一方强制下线。
项目创建完成后，在build.gradle中引入spring security依赖：
buildscript {
ext {
grailsVersion = project.grailsVersion
}
repositories {
mavenLocal()
maven { url "https://repo.grails.org/grails/core" }
}
dependencies {
classpath "org.grails:grails-gradle-plugin:$grailsVersion"
classpath "com.bertramlabs.plugins:asset-pipeline-gradle:2.8.2"
classpath "org.grails.plugins:hibernate4:5.0.5"
}
}
version "0.1"
group "springsecurity"
apply plugin:"eclipse"
apply plugin:"idea"
apply plugin:"war"
apply plugin:"org.grails.grails-web"
apply plugin:"org.grails.grails-gsp"
apply plugin:"asset-pipeline"
ext {
grailsVersion = project.grailsVersion
gradleWrapperVersion = project.gradleWrapperVersion
}
repositories {
mavenLocal()
maven { url "https://repo.grails.org/grails/core" }
}
dependencyManagement {
imports {
mavenBom "org.grails:grails-bom:$grailsVersion"
}
applyMavenExclusions false
}
dependencies {
//spring security权限依赖
compile 'org.grails.plugins:spring-security-core:3.1.2'

}
task wrapper(type: Wrapper) {
gradleVersion = gradleWrapperVersion
}
assets {
minifyJs = true
minifyCss = true
}
依赖下载完成后，按住Ctrl+Alt+G，在commond里面输入：
s2-quickstart com.system User Role
他会自动帮你创建User、Role以及UserRole类，grails-app/conf/application.groovy也会自动配置好，执行完成控制台提示:
|Creating User class 'User' and Role class 'Role' in package 'com.system'
|Rendered template Person.groovy.template to destination grails-app\domain\com\system\User.groovy
|Rendered template Authority.groovy.template to destination grails-app\domain\com\system\Role.groovy
|Rendered template PersonAuthority.groovy.template to destination grails-app\domain\com\system\UserRole.groovy

************************************************************
* Created security-related domain classes. Your *
* grails-app/conf/application.groovy has been updated with *
* the class names of the configured domain classes; *
* please verify that the values are correct. *
************************************************************
在src/main/groovy下面创建package为com.custom并创建ConcurrentSingleSessionAuthenticationStrategy类
package com.custom
import org.springframework.security.core.Authentication
import org.springframework.security.core.session.SessionRegistry
import org.springframework.security.web.authentication.session.SessionAuthenticationStrategy
import org.springframework.util.Assert
import javax.servlet.http.HttpServletRequest
import javax.servlet.http.HttpServletResponse
/**
* 会话管理类
* @auther Lee
* @Date 2017/11/14 18:21
* return
*/
class ConcurrentSingleSessionAuthenticationStrategy implements SessionAuthenticationStrategy {
private SessionRegistry sessionRegistry
/**
* @param 将新的会话赋值给sessionRegistry
*/
public ConcurrentSingleSessionAuthenticationStrategy(SessionRegistry sessionRegistry) {
Assert.notNull(sessionRegistry, "SessionRegistry cannot be null")
this.sessionRegistry = sessionRegistry
}
/**
* 覆盖父类的onAuthentication方法
* 用新的session替换就的session
*/
public void onAuthentication(Authentication authentication, HttpServletRequest request, HttpServletResponse response) {
def sessions = sessionRegistry.getAllSessions(authentication.getPrincipal(), false)
def principals = sessionRegistry.getAllPrincipals()
sessions.each {
if (it.principal == authentication.getPrincipal()) {
it.expireNow()
}
}
}
}
打开grails-app/conf/spring/resource.groovy，配置DSL,注意导包
import com.custom.ConcurrentSingleSessionAuthenticationStrategy
import org.springframework.security.core.session.SessionRegistryImpl
import org.springframework.security.web.authentication.session.CompositeSessionAuthenticationStrategy
import org.springframework.security.web.authentication.session.RegisterSessionAuthenticationStrategy
import org.springframework.security.web.authentication.session.SessionFixationProtectionStrategy
import org.springframework.security.web.session.ConcurrentSessionFilter
// Place your Spring DSL code here
beans = {
sessionRegistry(SessionRegistryImpl)
//很重要
sessionFixationProtectionStrategy(SessionFixationProtectionStrategy){
migrateSessionAttributes = true
alwaysCreateSession = true
}
// "/login/already"为重定向请求
concurrentSingleSessionAuthenticationStrategy(ConcurrentSingleSessionAuthenticationStrategy,ref('sessionRegistry'))
registerSessionAuthenticationStrategy(RegisterSessionAuthenticationStrategy,ref('sessionRegistry'))
sessionAuthenticationStrategy(CompositeSessionAuthenticationStrategy,[ref('concurrentSingleSessionAuthenticationStrategy'), ref('sessionFixationProtectionStrategy'), ref('registerSessionAuthenticationStrategy')])
concurrentSessionFilter(ConcurrentSessionFilter, ref('sessionRegistry'), "/login/already")
// grails3.3.0用下面这个，查看源码发现ConcurrentSessionFilter类中重定向url的构造方法已被废弃，不生效
//concurrentSessionFilter(ConcurrentSessionFilter, ref('sessionRegistry'))
}
打开grails-app/conf/application.groovy，最后面加入
grails.plugin.springsecurity.filterChain.filterNames = [ 'securityContextPersistenceFilter', 'logoutFilter', 'concurrentSessionFilter', 'rememberMeAuthenticationFilter', 'anonymousAuthenticationFilter', 'exceptionTranslationFilter', 'filterInvocationInterceptor' ]
在init/BootStrap.groovy下面的init方法中添加启动任务，注意添加构造方法
import com.system.Role
import com.system.User
import com.system.UserRole
class BootStrap {
def init = { servletContext ->
//创建角色
def role1 = new Role(authority: "ROLE_ADMIN").save()
def role2 = new Role(authority: "ROLE_SUPSYS").save()
def role3 = new Role(authority: "ROLE_USER").save()
//创建用户
def user1 = new User(username: "admin", password: "admin").save()
def user2 = new User(username: "super", password: "super").save()
def user3 = new User(username: "user", password: "user").save()
//用户角色关联
UserRole.create user1, role1, true
UserRole.create user2, role2, true
UserRole.create user3, role3, true
}
def destroy = {
}
}
启动项目，访问http://localhost:8080
常见问题：
启动报错====>配置问题
无法登陆====>有可能用户密码未加密，请加密后再次运行
没有LoginController和auth.gsp怎么办？
1、找到spring-security-core包
2、拷贝login到你项目的views下面，可以自行修改样式
3、拷贝grails/plugin/springsecurity/LoginController到你项目的controller下面，自己建包
