如何在Grails安装中替换弹簧加载的罐子 [英] How can I replace springloaded jar in Grails installation

问题描述

我的Grails 2.1.5应用程序引发异常java.lang.ClassCastException:java.beans.WeakIdentityMap.这似乎是一个已知问题，在某些论坛上建议的解决方案是用1.1.2替换弹簧加载的jar版本1.1.1(或降级Java版本，我宁愿不这样做)

My Grails 2.1.5 app throws exception java.lang.ClassCastException: java.beans.WeakIdentityMap. This seems to be a known problem, and the resolution advised on some forums is to replace springloaded jar version 1.1.1 with 1.1.2 (or to downgrade the java version, which I would rather not do)

我该怎么做?我尝试替换Grails安装lib目录中的jar，我得到了:

How can I do that? I tried replacing the jar in Grails installation lib directory, and I got:

打开zip文件或JAR清单丢失时出错:C:/grails-2.1.5/lib/org.springsource.springloaded/springloaded-core/jars/springloaded-core-1.1.1.jar

Error opening zip file or JAR manifest missing : C:/grails-2.1.5/lib/org.springs ource.springloaded/springloaded-core/jars/springloaded-core-1.1.1.jar

因此它仍在寻找旧的1.1.1 jar文件.

So it's still looking for the old 1.1.1 jar file.

请告知

推荐答案

我必须针对Grails 3.1.8进行此操作，我下载了 springloaded-1.2.8.RELEASE.jar 并替换了它备份先前的1.2.6版本后，在< GRAILS_HOME> \ lib \ org.springframework \ springloaded \ jars 中.

I had to do this for Grails 3.1.8, I downloaded springloaded-1.2.8.RELEASE.jar and just replaced it in <GRAILS_HOME>\lib\org.springframework\springloaded\jars after backing up the previous 1.2.6 version.
