Groovy生成的类名

Question

我正在使用Java + Groovy脚本。 是否可以更改由Groovy生成的类名称（例如Script1.groovy，Script777.groovy等）？ 如果发生异常，很难找到正确的脚本:/

是的，可以为Groovy脚本设置自定义名称。你需要使用groovy.lang.GroovyClassLoader。例如：

GroovyClassLoader groovyClassLoader = new GroovyClassLoader();
Class<Script> parsedClass = groovyClassLoader.parseClass(scriptText, name);
Script script = scriptClass.newInstance();
script.run()
