【问题描述】：
我正在服务器上设置我的 java web 应用程序，但其余控制器给出 404 错误。
在我的本地系统上一切正常。
这是我在 java hibernate spring 中的第一个项目。
下面是我的代码：
UserLoginController.java
package org.jasyatra.controller;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;
import org.jasyatra.model.User;
import org.jasyatra.model.LoginAuthToken;
import org.jasyatra.service.UserLoginService;
import org.jasyatra.service.LoginAuthTokenService;
@RestController
public class UserLoginController {
@Autowired
UserLoginService userLoginService;
@Autowired
LoginAuthTokenService loginAuthTokenService;
@RequestMapping(value = "/user/login", method = RequestMethod.POST, headers = "Accept=application/json")
public Map login(@RequestBody User parameters) {
List<User> loginResponse = userLoginService.login(parameters);
Map<String, String> response = new HashMap<>();
if (loginResponse.size() > 0) {
response.put("result", "true");
response.put("id", Integer.toString(loginResponse.get(0).getId()));
response.put("type", loginResponse.get(0).getType());
response.put("firstName", loginResponse.get(0).getFirstName());
response.put("lastName", loginResponse.get(0).getLastName());
response.put("permissions", loginResponse.get(0).getPermissions());
List<LoginAuthToken> responseToken = loginAuthTokenService.getLatestToken(loginResponse.get(0).getId(),loginResponse.get(0).getType());
response.put("token", responseToken.get(0).getToken());
} else {
response.put("result", "false");
response.put("message", "Invalid mobile no or password!");
}
return response;
}
}
UserLoginDAO.java
package org.jasyatra.dao;
import java.util.List;
import org.hibernate.Query;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.jasyatra.model.User;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;
import org.jasyatra.service.HashService;
@Repository
public class UserLoginDAO {
@Autowired
private SessionFactory sessionFactory;
public List<User> login(User parameters) {
Session session = this.sessionFactory.getCurrentSession();
Query query = session.createQuery("from User where mobileNo=:mobileNo and password=:password and status=:status");
query.setParameter("mobileNo", parameters.getMobileNo());
query.setParameter("password", HashService.getHash(parameters.getPassword(), "SHA1"));
query.setParameter("status", "active");
List<User> response = query.list();
return response;
}
}
UserLoginService.java
package org.jasyatra.service;
import java.nio.charset.Charset;
import java.util.Date;
import java.util.List;
import java.util.Random;
import org.jasyatra.dao.UserLoginDAO;
import org.jasyatra.dao.LoginAuthTokenDAO;
import org.jasyatra.model.LoginAuthToken;
import org.jasyatra.model.User;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
@Service
public class UserLoginService {
@Autowired
UserLoginDAO userLoginDao;
@Autowired
LoginAuthTokenDAO loginAuthTokenDAO;
@Autowired
LoginAuthTokenService loginAuthTokenService;
@Transactional
public List<User> login(User parameters) {
List<User> login = userLoginDao.login(parameters);
LoginAuthToken loginAuthToken = new LoginAuthToken();
if (login.size() > 0 && login.get(0).getId() > 0) {
try {
loginAuthToken.setLoginId(login.get(0).getId());
loginAuthToken.setLoginType(login.get(0).getType());
byte[] array = new byte[7]; // length is bounded by 7
new Random().nextBytes(array);
String generatedString = new String(array, Charset.forName("UTF-8"));
String token = HashService.getHash(generatedString, "SHA1");
loginAuthToken.setDateCreated(new Date());
loginAuthToken.setToken(token);
loginAuthTokenService.save(loginAuthToken);
} catch (Exception e) {
e.printStackTrace();
}
}
return login;
}
}

我遇到的主要问题是，它能够运行 index.jsp 但不能运行控制器。可能是什么问题？
请指引我正确的方向。
谢谢
【问题讨论】：

请添加来自服务器的日志跟踪。另外，你说它在本地工作，但它不工作在哪里？？
-
许多 cmets：(1) 使用 JPA（带有 Hibernate）而不是传统的 Hibernate 接口。 (2) 使用 Spring Data 而不是手写 DAO。 (3) 使用 Spring Security 代替手写安全敏感代码。 (4) 使用 Spring Boot 而不是你的配置（你唯一需要的是
spring.datasource.url）和你的servlet映射（只是java -jar）。 (5) 使用构造函数注入代替字段注入。 (6) 使用正确的 HTTP 响应（例如 422）而不是success: false。 -
404 表示，找不到资源。 POST 请求是如何发出的？请分享用于访问服务器的 URL
-
@chrylis 我知道我的代码不是最好的，因为这是我的第一个项目。我仍处于学习阶段，但由于这是实时项目，我需要让它在服务器上运行。我如何找出我做错了什么让它给我 404 ？
