Spring MVC: How to call @Service class from another project

Question

I'm having a problem right now, Is it possible to use anotated @Service class from another Maven Spring MVC project? I've already done this step: Build Path -> Configure Path -> Add Project

Now, I'm trying to use some annotated service method from added project.

the following code is my controller class and i want to use CustomerService class method from another project which I already added in configure path.

CustomerController.java

//this class is from another project
private CustomerService customerService;

public ModelAndView searchCustomer(@RequestParam String lastname) {
    CustomerService customerService = this.customerService.findByLastName(lastname);

}

Or is there any alternate way to use annotated Service class from another project?

Thanks in advance..

如果执行此操作，则可以：1.将源Java文件复制到我的新项目中。2.将另一个项目导出到jar中，然后导入到我的新项目中。

Consider breaking your application into web, service and DAL layer into different maven modules like below:-

• Main Project (bundled as pom)
• Web module (bundled as war with Service dependency)
• Service (bundled as jar with DAL dependency)
• DAL (bundled as jar)

Above structure gives you enough flexibility to plug out Services (as jar) and include it in any other application
