如何解决Grails 3升级-无法解析类grails.plugin.rendering.pdf.PdfRenderingService
我继承了基于Grails 2.5.4的多模块grails应用程序。
我安装了groovy 3.0.4和grails 3.3.11,并根据官方网站(https://docs.grails.org/3.0.x/guide/upgrading.html)提供的教程完成了grails升级任务。
我正在处理大量的代码自适应,但是在尝试构建项目时遇到了一个特定的问题,我面临以下问题:
C:\repo\upgraded-app\myapp-web\grails-app\services\bitt\PdfRenderingService.groovy: 9: unable to resolve class grails.plugin.rendering.pdf.PdfRenderingService
@ line 9,column 1.
@Transactional
^
涉及的代码如下:
import com.lowagie.text.pdf.BaseFont
import grails.transaction.Transactional
import grails.util.Environment
import org.w3c.dom.Document
import org.xhtmlrenderer.pdf.ITextRenderer
@Transactional
class PdfRenderingService extends grails.plugin.rendering.pdf.PdfRenderingService {
...
和我的build.gradle文件如下:
buildscript {
repositories {
mavenLocal()
maven { url "https://repo.grails.org/grails/core" }
}
dependencies {
classpath "org.grails:grails-gradle-plugin:$grailsVersion"

systemProperty "webdriver.gecko.driver",System.getProperty('webdriver.gecko.driver')
}
assets {
minifyJs = true
minifyCss = true
includes = ["fonts/*"]
}
上面提到的代码在Grails 2中运行良好...但是现在在Grails 3中引发了编译错误...任何想法为什么?
谢谢。
解决方法
主要Grails版本之间的升级并不那么容易,因为Gradle配置存在很大差异。
我建议您使用Grails Starter来获取示例应用程序,从那里解压缩build.gradle
,gradle.properties
,然后将旧配置(主要是依赖项)合并到其中。
配置也已从.groovy文件更改为.yml,也考虑将其迁移。
