邮递员给出 401 Unauthorized - Spring Boot & MYSQL
Postman gives 401 Unauthorized - Spring Boot & MYSQL
首先：是的，我知道已经有很多人问过这个问题，但没有人真正帮助我。
其次：
-我已经尝试使用我的用户名+密码从 MySQL 凭证创建一个简单的 Auth 到 Postman 但没有成功
我已经尝试从 postman 中删除 cookie，但没有成功。
描述：
link 我的灵感来源：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 网络应用程序。
每次我尝试向 Postman 发出 POST 请求时，它都没有给我任何信息（401 Unathorized），如下所示：
它只给我“401 Unauthorized”。
当然，当我 运行 项目时，它会给我 MYSQL
中显示的数据库
项目内容如下：（那个YML文件里面什么都没有）
这是一些代码：
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
还有我的控制器配置：
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 网络应用程序想要执行的“服务”配置。 （例如，我想 POST 一个带有“名称”、“数量”、“价格”的请求到我的 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);
}
}

从一开始就是我的错：它是从 IntelliJ“Spring 安全”的复选框中自动选中的。我取消选中它，一切正常。
首先：是的，我知道已经有很多人问过这个问题，但没有人真正帮助我。
其次：
-我已经尝试使用我的用户名+密码从 MySQL 凭证创建一个简单的 Auth 到 Postman 但没有成功
我已经尝试从 postman 中删除 cookie，但没有成功。
描述：
link 我的灵感来源：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 网络应用程序。 每次我尝试向 Postman 发出 POST 请求时，它都没有给我任何信息（401 Unathorized），如下所示：
它只给我“401 Unauthorized”。
当然，当我 运行 项目时，它会给我 MYSQL
中显示的数据库项目内容如下：（那个YML文件里面什么都没有）
这是一些代码：
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
还有我的控制器配置：
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 网络应用程序想要执行的“服务”配置。 （例如，我想 POST 一个带有“名称”、“数量”、“价格”的请求到我的 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);
}
}
