1.官网下载安装grails,配置path环境变量到bin目录下

在命令行输入grails查看变化，如果运行成功就代表安装成功了

安装idea开发工具

2.build.gradle配置文件设置

compile 'org.grails.plugins:spring-security-core:3.1.1'
    runtime 'mysql:mysql-connector-java:5.1.39'

一个用来配置闭包用户登录权限设置

一个用来配置mysql jdbc驱动

3.mysql配置

dataSource: pooled: true
        jmxExport: true
        driverClassName: com.mysql.jdbc.Driver
        username: yangchuan
        password: 2719283s+
    
    environments: development: dataSource: dbCreate: update
                url: jdbc:mysql://localhost:3306/tianxing?useUnicode=true&characterEncoding=UTF-8&useSSL=false
        test: dataSource: dbCreate: create-drop
                url: jdbc:mysql://101.251.244.37:3306/tianxing?useUnicode=true&characterEncoding=UTF-8&useSSL=false
        production: dataSource: dbCreate: update
                url: jdbc:mysql://10.0.8.100:3306/tianxing?useUnicode=true&characterEncoding=UTF-8&useSSL=false
                properties: jmxEnabled: true
                    initialSize: 5
                    maxActive: 50
                    minIdle: 5
                    maxIdle: 25
                    maxWait: 10000
                    maxAge: 600000
                    timeBetweenEvictionRunsMillis: 5000
                    minEvictableIdleTimeMillis: 60000
                    validationQuery: SELECT 1
                    validationQueryTimeout: 3
                    validationInterval: 15000
                    testOnBorrow: true
                    testWhileIdle: true
                    testOnReturn: false
                    jdbcInterceptors: ConnectionState
                    defaultTransactionIsolation: 2 # TRANSACTION_READ_COMMITTED

要注意格式对称以及首行缩进问题，如果配置标准不一致就会运行失败.

4.用户登陆设置

使用命令grails s2-quickstart    com.test User Role 创建用户账户domian

使用命令grails generate-all   com.test.User 来创建需要的view和controller

在init目录下的BootStrap中配置用户名与密码:

package dfhfax
    
    import com.dfhfax.Role
    import com.dfhfax.User
    import com.dfhfax.UserRole
    
    class BootStrap {
    
        def init = { servletContext ->
            if(Role.count()<1){
                println 'init role data'
                def r = new Role()
                r.authority='ROLE_ADMINISTRATOR'
                r.save()
            }
    
            if (User.count() < 1)
            {
                println 'init user data'
    
                def c = new User()
                c.username = 'yangchuan'
                c.password = '2719283s+'
                c.save()
    
            }
    
            if (UserRole.count() < 1)
            {
                println 'init user role data'
                UserRole.create(User.findByUsername('yangchuan'), Role.findByAuthority('ROLE_ADMINISTRATOR'))
            }
        }
        def destroy = {
        }
    }

在需要访问页面对应的controller上添加访问权限的标识

@Secured(['ROLE_ADMINISTRATOR'])
