使用 @Autowire 注入时警告：Field injection is not recommended
被警告代码：
@Autowired | |
private EduWorkInfoMapper eduWorkInfoMapper; | |
@Autowired | |
private IEduExportUserInfoService eduExportUserInfoService; |
原因：不建议使用属性注入，其实当你鼠标滑动到 @Autowired 上面，同时按下 alt+enter 键时，就会看到下面这样的提示 xxx to constructor, 这说明编辑器建议你使用构造注入的方式进行 bean 的注入。
