javax.inject.jar：依赖注入非常方便的jar包

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;
    }
}

 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;


}
