springBoot 添加自定义类库包

一、新建SpringBoot Web

二、添加类库包

com.saas.pdf

删除掉多余的类，新建类：PdfUtil.java

package com.saas.pdf;

public class PdfUtil {
    public static void Save(String filePath) {
        System.out.println("保存成功！");
    }
}

?三、com.saas.swaggerdemogit引用项目com.saas.pdf

打开Open Module Settings

?在ProductController调用：PdfUtil.Save("c://a.pdf");

package com.saas.swaggerdemo.controllers;

import com.saas.pdf.PdfUtil;
import com.saas.swaggerdemo.ProductDto;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;
import org.springframework.web.bind.annotation.*;

@RestController
@Api(value = "ProductController")
@RequestMapping("/products")
public class ProductController {

    @ApiOperation(value = "保存产品")
    @PostMapping("save")
    public boolean SaveProduct(@RequestBody ProductDto productDto) {
        PdfUtil.Save("c://a.pdf");
        return true;
    }
}

运行：
