Spring Security OAuth项目提供所有可能开发使用的Spring OAuth2用户兼容实现所需的API。 Official Spring security oauth项目提供了实现 OAuth2 一个完整的例子。这个篇文章的代码示例是在这个官方提供的例子的基础上修改。这篇文章的目的是只使用所需最低限度的功能，以演示我们的REST API，仅此而已。我也还在学习，所以如果有什么不对的地方随时纠正我。
如果凭据 OK 授权服务器是一个负责验证凭据，提供令牌[刷新令牌以及访问令牌]。它还包含有关注册客户和访问范围以及授权类型的信息。 令牌存储用于存储令牌。我们将使用内存来存储令牌。@EnableAuthorizationServer使一个授权服务器(即，AuthorizationEndpoint和TokenEndpoint)在当前的应用程序上下文。
POST http://localhost:8080/SpringSecurityOAuth2Example/oauth/token?grant_type=refresh_token&refresh_token=094b7d23-973f-4cc1-83ad-8ffd43de1845
使用 access_token 查询参数和要求提供访问资源的令牌。
GET http://localhost:8080/SpringSecurityOAuth2Example/user/?access_token=3525d0e4-d881-49e7-9f91-bcfd18259109
5. Rest API
简单的Spring REST API，在前面教程文章中我们使用的那样。
package com.yiibai.springmvc.controller;
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.http.HttpHeaders;
import org.springframework.http.HttpStatus;
import org.springframework.http.MediaType;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.PathVariable;
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.springframework.web.util.UriComponentsBuilder;
import com.yiibai.springmvc.model.User;
import com.yiibai.springmvc.service.UserService;
@RestController
public class HelloWorldRestController {
@Autowired
UserService userService; //Service which will do all data retrieval/manipulation work
//-------------------Retrieve All Users--------------------------------------------------------
@RequestMapping(value = "/user/", method = RequestMethod.GET)
public ResponseEntity> listAllUsers() {
List users = userService.findAllUsers();
if(users.isEmpty()){
return new ResponseEntity>(HttpStatus.NO_CONTENT);//You many decide to return HttpStatus.NOT_FOUND
}
return new ResponseEntity>(users, HttpStatus.OK);
}
//-------------------Retrieve Single User--------------------------------------------------------
@RequestMapping(value = "/user/{id}", method = RequestMethod.GET, produces = {MediaType.APPLICATION_JSON_VALUE,MediaType.APPLICATION_XML_VALUE})
public ResponseEntity getUser(@PathVariable("id") long id) {
System.out.println("Fetching User with id " + id);
User user = userService.findById(id);
if (user == null) {
System.out.println("User with id " + id + " not found");
return new ResponseEntity(HttpStatus.NOT_FOUND);
}
return new ResponseEntity(user, HttpStatus.OK);
}
//-------------------Create a User--------------------------------------------------------
@RequestMapping(value = "/user/", method = RequestMethod.POST)
public ResponseEntity createUser(@RequestBody User user, UriComponentsBuilder ucBuilder) {
System.out.println("Creating User " + user.getName());
if (userService.isUserExist(user)) {
System.out.println("A User with name " + user.getName() + " already exist");
return new ResponseEntity(HttpStatus.CONFLICT);
}
userService.saveUser(user);
HttpHeaders headers = new HttpHeaders();
headers.setLocation(ucBuilder.path("/user/{id}").buildAndExpand(user.getId()).toUri());
return new ResponseEntity(headers, HttpStatus.CREATED);
}
//------------------- Update a User --------------------------------------------------------
@RequestMapping(value = "/user/{id}", method = RequestMethod.PUT)
public ResponseEntity updateUser(@PathVariable("id") long id, @RequestBody User user) {
System.out.println("Updating User " + id);
User currentUser = userService.findById(id);
if (currentUser==null) {
System.out.println("User with id " + id + " not found");
return new ResponseEntity(HttpStatus.NOT_FOUND);
}
currentUser.setName(user.getName());
currentUser.setAge(user.getAge());
currentUser.setSalary(user.getSalary());
userService.updateUser(currentUser);
return new ResponseEntity(currentUser, HttpStatus.OK);
}
//------------------- Delete a User --------------------------------------------------------
@RequestMapping(value = "/user/{id}", method = RequestMethod.DELETE)
public ResponseEntity deleteUser(@PathVariable("id") long id) {
System.out.println("Fetching & Deleting User with id " + id);
User user = userService.findById(id);
if (user == null) {
System.out.println("Unable to delete. User with id " + id + " not found");
return new ResponseEntity(HttpStatus.NOT_FOUND);
}
userService.deleteUserById(id);
return new ResponseEntity(HttpStatus.NO_CONTENT);
}
//------------------- Delete All Users --------------------------------------------------------
@RequestMapping(value = "/user/", method = RequestMethod.DELETE)
public ResponseEntity deleteAllUsers() {
System.out.println("Deleting All Users");
userService.deleteAllUsers();
return new ResponseEntity(HttpStatus.NO_CONTENT);
}
}
我们需要一个新的访问令牌。触发一个 post 以后用刷新令牌来获得一个新的访问令牌。请求URL：http://localhost:8080/SpringSecurityOAuth2/oauth/token?grant_type=refresh_token&refresh_token=fefcf12c-2683-4f1a-a446-941666dcfe23
public class Server
{
//用来存储所有连接上来的客户
private List<ServerThread> clients;
public static void main(String[] args)
{
Server s = new Server();
s.startServer(9988);
}
publi
I got serveral questions about auto.offset.reset. This configuration parameter governs how consumer read the message from Kafka when there is no initial offset in ZooKeeper or
two cursors.
Make the first cursor go K steps first.

ListNode p1=head,p2=head;
一、sh 脚本不执行的原因
sh脚本不执行的原因 只有2个
1.权限不够
2.sh脚本里路径没写完整。
二、解决You have new mail in /var/spool/mail/root
修改/usr/share/logwatch/default.conf/logwatch.conf配置文件
MailTo =
MailFrom
三、查询连接数
$ git push joe prod-2295-1

! [rejected] prod-2295-1 -> prod-2295-1 (non-fast-forward)
