邮递员给出 401 Unauthorized - Spring Boot 和 MYSQL [关闭]答案

【问题标题】：Postman gives 401 Unauthorized - Spring Boot & MYSQL [closed]邮递员给出 401 Unauthorized - Spring Boot 和 MYSQL [关闭]
【发布时间】：2021-08-21 16:12:41
【问题描述】：

首先：是的，我知道这个问题已经问了很多，但没有人真正帮助过我。

其次：

-我尝试使用我的用户名+密码从 MySQL 凭据到 Postman 进行简单的身份验证，但没有成功

我尝试从邮递员中删除 cookie，但没有成功。

说明：

我得到这个想法的链接：youtube link for this crud web app

我正在尝试使用 Spring Boot、Lombok、JPA 和 Hibernate、MySQL 开发一个简单的 CRUD Web 应用程序。每次我尝试向 Postman 发出 POST 请求时，它都没有给我任何东西（401 Unathorized），如下所示：

它只给我“401 Unauthorized”。

当然，当我运行项目时，它会为我提供 MYSQL 中显示的数据库

这是项目内容：（那个YML文件里面什么都没有）

这里有一些代码：

application.properties

spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
spring.datasource.url = jdbc:mysql://localhost:3306/javatechie
spring.datasource.username = root
spring.datasource.password = rooti
spring.jpa.show-sql = true
spring.jpa.hibernate.ddl-auto = update
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect
server.port=9191

也是我对控制器的配置：

package com.javatechie.crud.example.controller;

import com.javatechie.crud.example.entity.Product;
import com.javatechie.crud.example.service.ProductService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;
import java.util.List;

@RestController
public class ProductController {

    @Autowired
    private ProductService service;

    @PostMapping("/addProduct")
    public Product addProduct(@RequestBody Product product){
        return service.saveProduct(product);

    }
    @PostMapping("/addProducts")
    public List<Product> addProduct(@RequestBody List<Product> product){

        return service.saveProducts(product);

    }
    @GetMapping("/products")
    public List<Product> findAllProducts(){
        return service.getProducts();


    }
    @GetMapping("/product/{id}")
    public Product findProductById(@PathVariable int id){
        return service.getProductById(id);
    }
    @GetMapping("/product/{name}")
    public Product findProductByName(@PathVariable String name){
        return service.getProductByName(name);
    }


    @PutMapping("/update")
    public Product updateProduct(@RequestBody Product product){
        return service.updateProduct(product);

    }
    @DeleteMapping("/delete/{id}")
    public String deleteProduct(@PathVariable int id){
        return service.deleteProduct(id);
    }


}

还有我的 CRUD Web 应用想要执行的“服务”配置。（例如，我想将带有“名称”、“数量”、“价格”的请求发布到我的 MYSQL 数据库中）

package com.javatechie.crud.example.service;

import com.javatechie.crud.example.entity.Product;
import com.javatechie.crud.example.repository.ProductRepository;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import java.util.ArrayList;
import java.lang.Integer;
import java.util.List;

@Service
public class ProductService {
    @Autowired
    private ProductRepository repository;

    public Product saveProduct(Product product){
        return repository.save(product);
    }

    public List<Product> saveProducts(List<Product> products){
        return repository.saveAll(products);
    }

    public List<Product> getProducts(){
        return repository.findAll();
    }
    public Product getProductById(int id){
        return repository.findById(id).orElse(null);
    }

    public Product getProductByName(String name){
        return repository.findByName(name);
    }
    public String deleteProduct(int id){
        repository.deleteById(id);
        return "product removed || "+id;
    }

    public Product updateProduct(Product product){
        Product existingProduct=repository.findById(product.getId()).orElse(product);
        existingProduct.setName(product.getName());
        existingProduct.setQuantity(product.getQuantity());
        existingProduct.setPrice(product.getPrice());
        return repository.save(existingProduct);
    }

}

【问题讨论】：

您在使用 Spring Security，您是否有安全配置，如果有，请分享一下？当您收到 401 响应时，您是否还可以分享您的应用程序的日志？
@EleftheriaStein-Kousathana 我的项目没有任何安全配置。我没有提到这一点，非常抱歉。还有来自应用程序的日志：imgur.com/a/78mYIWB
你有 Spring Security 依赖吗？像spring-boot-starter-security 这样的东西？你能分享正在运行的 Spring 应用程序的日志，而不是 Postman 的日志吗？
@EleftheriaStein-Kousathana 我已经使用 Spring 中的日志（使用 IntelJ IDE）编辑了我的帖子，而且不，我没有安全依赖项。从我发布的教程中，它不使用一个（我什至放了链接）。所以我不知道为什么它对我不起作用，向邮递员发出 POST 请求。
日志显示您正在使用 Spring Security Using generated security password: ae5d43ed-6daf-4bd0-af28-6a3556efa3d9。第一步是找出安全依赖的来源。如果您不明白，请随时分享您的 pom.xml。

【解决方案1】：

从一开始就是我的错：它是从 IntelliJ“Spring Security”中的复选框自动选中的。我取消选中它，一切正常。
