如何自动连接另一个项目中的课程 [英] How to autowire a class which is in another project

问题描述

我有两个Java项目，分别是epService和epEntity(用于数据库访问的工厂类).还有一个名为epWeb的Spring项目，其中包含控制器，这是Rest API. 现在，我想将epEntity内部的类自动连接到春季项目epWeb. 我已经成功地自动在该epWeb项目中自动连接了类，但是我无法从另一个项目中自动连接一个类 任何人都有这样做的建议，请让我知道. 如果这是与stackoverflow无关的问题，请删除它.

I have two java projects as epService and epEntity (factory classes for db access). And there is another Spring project as epWeb which contains controllers and this is a Rest API. Now, I want to autowire a class which is inside epEntity to the spring project epWeb. I have successfully autowired classes within that epWeb project but I was unable to autowire a class from another project Anyone have a suggestion for doing that, please let me know. If this is an irrelevant question for stackoverflow, please delete this.

    this.sessionFactory = sessionFactory;

推荐答案

您可以在主应用程序epWeb中使用@ComponentScan批注，以便将在epEntity项目中存在的Spring上下文类注册为Bean(控制器) ，服务等).

You can use @ComponentScan annotation in your main application epWeb in order to register in Spring context classes which live in epEntity project as Beans (Controllers, Services etc).

@ComponentScan({"com.example.service", "com.example.controlle‌​r"})

此外，请确保在epEntity项目中使用@Service注释服务实现.

Also, make sure that Service implementations are annotated with @Service in epEntity project.
