我如何在 src/groovy/类中使用“日志" [英] How can i use 'log' inside a src/groovy/ class

问题描述

我遇到了这个错误:

groovy.lang.MissingPropertyException:没有这样的属性:日志类:org.utils.MyClass

groovy.lang.MissingPropertyException: No such property: log for class: org.utils.MyClass

课程内容如下:

package org.utils

class MyClass {
    int organizationCount = 0

    public int getOrganizationCount(){
        log.debug "There are ${organizationCount} organization(s) found."
        return organizationCount
    }

}

我需要添加导入语句吗?我需要添加什么?请注意，该类位于 src/groovy/org/utils 中.我知道可以在控制器、服务等中访问log"变量.在src"类中不确定.

Do i need to add an import statement? What do i need to add? Note that the class is located in src/groovy/org/utils. I know that the 'log' variable is accessible in controllers, services, etc. Not sure in 'src' classes.

谢谢.

推荐答案

在 grails 3 中，默认的日志系统是 logback.只需将 @Slf4j 注释添加到您的 src/groovy 类即可解决问题.

In grails 3, the default logging system is logback. Simply adding the @Slf4j annotation to your src/groovy class will take care of things.

import groovy.util.logging.Slf4j

@Slf4j
class MyUtil {
