Spring 引导控制器需要找不到类型为 'org.dozer.Mapper' 的 bean
Spring Boot controller required a bean of type 'org.dozer.Mapper' that could not be found
我创建了一个 spring 引导项目并添加了
compile('net.sf.dozer:dozer:5.5.1')
依赖关系。但是 class、org.dozer.Mapper 无法被我的应用程序识别。
我 运行 gradle clean、gradle buildDependents 和 gradle build。
但是事情并没有改变。
我该怎么办？
