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 dfhfaximport com.dfhfax.Roleimport com.dfhfax.Userimport com.dfhfax.UserRoleclass 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'])
