Maven项目中如何引入本地的jar包或者sdk

1、没有导入的时候

package com.xjj.controller;


import com.xjj.service.InterfaceService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

/**
 * @Date 2020/3/14 10:58
 * @author xjj
 */
@Controller
@RequestMapping("/interface")
public class InterfaceController {
    @Autowired
    private InterfaceService interfaceService;

    public void test(){
        AlipayClient alipayClient = new DefaultAlipayClient("asd", "asd", "asd", "json", "asd", "asd", "asd");
    }

}

2、创建lib文件夹，并向其中引入需要的文件

3、在pom.xml文件中添加路径，其中的groupId和artifactId,version等信息可以随便填写，主要是路径一定要填写正确

<dependency>
  <groupId>com.ali</groupId>
  <artifactId>pay</artifactId>
  <version>1.0</version>
  <scope>system</scope>
  <systemPath>${project.basedir}/src/main/webapp/WEB-INF/lib/alipay-sdk-java20170324180803.jar</systemPath>
</dependency>

4、然后会自动的引入我们需要的依赖

package com.xjj.controller;


import com.alipay.api.AlipayClient;
import com.alipay.api.DefaultAlipayClient;
import com.xjj.service.InterfaceService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

/**
 * @Date 2020/3/14 10:58
 * @author xjj
 */
@Controller
@RequestMapping("/interface")
public class InterfaceController {
    @Autowired
    private InterfaceService interfaceService;

    public void test(){
        AlipayClient alipayClient = new DefaultAlipayClient("asd", "asd", "asd", "json", "asd", "asd", "asd");
    }

}
