grails项目使用qrcode插件:

(1)在BuildConfig.groovy中引入安装插件:

    plugins {
        runtime ":hibernate:$grailsVersion"
        runtime ":jquery:1.8.3"
        runtime ":resources:1.1.6"

        // Uncomment these (or add new ones) to enable additional resources capabilities
        //runtime ":zipped-resources:1.0"
        //runtime ":cached-resources:1.0"
        //runtime ":yui-minify-resources:0.1.4"

        build ":tomcat:$grailsVersion"

        runtime ":database-migration:1.2.1"

        compile "org.grails.plugins:qrcode:0.7"

    }

若提示安装插件不成功,就为其指定下载来源:

    repositories {
        inherits true // Whether to inherit repository definitions from plugins

        grailsPlugins()
        grailsHome()
        grailsCentral()

        mavenLocal()
        mavenCentral()
        mavenRepo "http://repo.grails.org/grails/plugins/"

    }

(2)插件安装成功后,在gsp页面直接引用就可以了:

<qrcode:image text="${wxurl}"/>
