spring boot api 不工作..在 Eclipse 控制台中也没有显示任何错误

Question

这是我的 UserController class

package ritu.login;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Configuration;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.DeleteMapping;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.PutMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
@Configuration  
@RequestMapping("/vs1")
public class UserController {

    @Autowired
    UserService userService;

    @GetMapping("/users")
    public List<User> getAllUsers() {
        return userService.getAllUsers();
    }

    @GetMapping("/user/{id}")
    private User getUser(@PathVariable("id") long id) {
        return userService.getUserById(id);
    }

    @DeleteMapping("/user/{id}")
    public void deleteUser(@PathVariable("id") long id) {
        userService.delete(id);
    }

    @PostMapping("/users")
    public long saveUser(@RequestBody User user) {
        userService.saveOrUpdate(user);
        return user.getId();
    }

    @PutMapping("/users")
    public User Update(@RequestBody User users) {
        userService.saveOrUpdate(users);
        return users;
    }
}

这里是用户服务class

package ritu.login;

import java.util.ArrayList;
import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

@Service
public class UserService {

    @Autowired
    UserRepository userRepository;

    public List<User> getAllUsers() {
        List<User> users = new ArrayList<User>();
        userRepository.findAll().forEach(user1 -> users.add(user1));
        return users;
    }

    public User getUserById(long id) {
        return userRepository.findById(id).get();
    }

    public void saveOrUpdate(User users) {
        userRepository.save(users);
    }

    public void delete(long id) {
        userRepository.deleteById(id);
    }

    public void update(User users, long id) {
        userRepository.save(users);
    }
}

这是我的 pom.xml

这是我在邮递员[=35=]中的

http://localhost:8080/vs1/users

它给出错误 404 Not found..我该怎么办？这是 Pojo class

package ritu.login;

    public Long getId() {

    public void setId(Long id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

            Connection con = DriverManager.getConnection("jdbc:mysql://localhost:3306/any", "root", "jaygurudev1@");
            PreparedStatement ps = con.prepareStatement("Select id,name from user where id=? and name=?");
            ps.setLong(1, id);
            ps.setString(2, name);
            ResultSet rs = ps.executeQuery();

            if (rs.next()) {
                return "hello.xhtml";
            } else {
                FacesContext.getCurrentInstance().addMessage(null, new FacesMessage(FacesMessage.SEVERITY_WARN,
                        "Incorrect Username and Passowrd", "Please enter correct username and Password"));
                return  "index";
            }

        } catch (Exception e) {
            System.out.println("in exception");
        }
        return null;
    }
}

我在 javatpoint 和其他网站上看到了一些教程，但问题仍然无法解决。我在代码中缺少什么或任何与版本相关的问题？ 点击 URL

时出现 404 错误

Answer 1

因为，eclipse 显示错误我必须在构建路径中添加 annotation.api jar 之后我 从 [=15] 中删除了 spring 安全依赖项 =] 完全有效
