javax.inject.jar（依赖注入非常方便的jar包） JavaEE

用过Spring框架的我们都知道，每当生成依赖注入的时候，我们都必须生成相应类的set方法，而且要在set方法上面写上@Autowired，才能实现依赖注入，如下：

package com.kaishengit.web; import com.kaishengit.service.ProjectService; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Controller; @Controller public class FolderController { private ProjectService projectService; //set @Autowired public void setProjectService(ProjectService projectService) { this.projectService = projectService; } }

【javax.inject.jar（依赖注入非常方便的jar包）】 每次都要生成相应的set方法感觉好麻烦，现在如果我们使用javax.inject.jar，只需要在相应类的属性上面加上@Inject，如下代码：

package com.kaishengit.web; import com.kaishengit.service.ProjectService; import org.springframework.stereotype.Controller; import javax.inject.Inject; @Controller public class FolderController { @Inject private ProjectService projectService; }
