当前位置 博文首页 > li5672的专栏：使用Maven构建多模块项目
打开idea创建一个新的项目，选择Spring Initailizr,下一步下一步，创建好一个项目。
创建好之后只保留pom文件，其他全部删除
在根目录上右键新增模块，如下图，选择Module之后和创建项目一样，下一步下一步。
……
创建好了三个项目，project项目保留启动类，其他两个项目只保留src目录和pom文件

@Service
public class ProjectService {
public String sendMessage() {
return "maven test";
}
}
@RestController
@RequestMapping("/api/")
public class ProjectController {
@Autowired
private ProjectService projectService;
@GetMapping("test")
public String mess() {
return projectService.sendMessage();
}
}
pom文件中新增

dev和prod要放到直接放到resources中，不能放在子目录中，不知道为什么
启动代码，访问 http://localhost:8080/api/test
