Grails 之 Acegi Plugin 转移到Spring Security Core Plugin

现在Acegi Plugin插件已经停止开发了，已经转移到了Spring Security Core Plugin了。它们虽然师出同门，还是有很多地方需要调整的。

以下是官方文档，新入手看了这些还是有点蒙的，具体在文章后面进行解说。

3 Migrating from the Acegi Plugin

If you formerly used the Acegi plugin, change your application configuration settings as follows.

Setting	Spring Security Plugin	Acegi Plugin
Enabled by default	true	false
Cache UserDetails by default	false	true
Configuration location	grails-app/conf/ Config.groovy	grails-app/conf/ SecurityConfig.groovy
Security service	springSecurityService	authenticateService

The table shows names of corresponding configuration properties.

The plugin's configuration values all start with

grails.plugins.springsecurity

to distinguish them from similarly named options in Grails and from other plugins. You must specify
all property overrides with the

grails.plugins.springsecurity

suffix. For example, you specify the attribute

password.algorithm

as:

grails.plugins.springsecurity.password.algorithm='SHA-512'

in

Config.groovy

问题一、

Acegi Plugin插件是在rails-app/conf/ SecurityConfig.groovy里面的，而Spring Security是在grails-app/conf/Config.groovy的，这点不复杂，官方文档也有说道。

问题二、

很多命名已经更改了，这个上文也有提到，如果没什么印象，可在看看上面的官方文档。

问题三、

这个问题比较关键Acegi Plugin插件默认的密码编码是与Spring Security默认编码是不一样的，所以需要在Config.groovy里面指定编码，如果以前使用的是MD5则需要重新配置为MD5，如下：

grails {
plugins {
springsecurity {
...
password.algorithm = "MD5"
...
}
}
}

读取配置文件

Spring Security CorePlugin读取配置文件的方式为 SpringSecurityUtils.securityConfig

页面读取登录信息

采用了sec标签，如<sec:ifLoggedIn>，更多标签可见：http://grails-plugins.github.com/grails-spring-security-core/docs/manual/guide/6%20Helper%20Classes.html#6.1%20SecurityTagLib

工具类与service类，目前能够用到的主要是这两个类里面的方法

org.codehaus.groovy.grails.plugins.springsecurity.SpringSecurityUtils

grails.plugins.springsecurity.SpringSecurityService
