java“状态”:404,“错误”:“未找到”,“路径”:“/GetProduct”
我的控制器类是-
package com.javatechie.crud.example.controller;
import java.io.IOException;
import java.sql.SQLException;
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestBody;
import com.javatechie.crud.example.entity.Product;
import com.javatechie.crud.example.service.ProductService;
public class ProductListController {
@Autowired
private ProductService service;
@GetMapping("/GetProduct")
public List<Product> addProducts(@RequestBody Product products) throws IOException, ClassNotFoundException, SQLException {
System.out.println("Inside addProducts controller method");
return service.saveProducts(1);
}
}
我的实体类是-
package com.javatechie.crud.example.entity;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.Table;
@Entity
@Table(name="PRODUCT_TBL")
public class Product {
@Id
@GeneratedValue
private int id;
private String name;
private String quantity;
private double price;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getQuantity() {
return quantity;
}
public void setQuantity(String quantity) {
this.quantity = quantity;
}
public double getPrice() {
return price;
}
public void setPrice(double price) {
this.price = price;
}
}
JpaRepository实现是-
package com.javatechie.crud.example.entity;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.Table;
@Entity
@Table(name="PRODUCT_TBL")
public class Product {
@Id
@GeneratedValue
private int id;
private String name;
private String quantity;
private double price;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getQuantity() {
return quantity;
}
public void setQuantity(String quantity) {
this.quantity = quantity;
}
public double getPrice() {
return price;
}
public void setPrice(double price) {
this.price = price;
}
}
服务级别是-
package com.javatechie.crud.example.service;
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import com.javatechie.crud.example.entity.Product;
import com.javatechie.crud.example.repository.ProductRepository;
@Service
public class ProductService {
@Autowired
private ProductRepository repository;
public List<Product> saveProducts(int id) {
return repository.GetRepo(id);
}
}
而且,它给出的意外输出是-
数据库表如下所示-
我期望的输出是json主体,sql记录具有id、名称、价格和数量。如何仅使用本机查询实现此输出?请帮忙

您应该添加@RestController和@RequestMapping注释来处理传入的REST请求
