本文讲述spring-boot工程中使用spring-session机制进行安全认证,并且通过redis存储session,满足集群部署、分布式系统的session共享。
java工程中,说到权限管理和安全认证,我们首先想到的是Spring Security和Apache Shiro,这两者均能实现用户身份认证和复杂的权限管理功能。但是如果我们只是想实现身份认证(如是否登录、会话是否超时),使用session管理即可满足。本文目录如下:
目录:
1. 创建spring-boot项目
2. 用户管理
3. 用户身份认证
4. spring-session配置
5. 使用redis共享session
一、创建spring-boot项目
1、工程使用idea+gradle搭建,jdk1.8,spring-boot版本2.0.2.RELEASE,数据库postgreSQL,持久层spring-data-jpa;
2、新建spring-boot项目,工程type选择Gradle Project;
3、勾选初始化依赖如下:
创建完成后gradle.build文件内容如下:
buildscript {
ext {
springBootVersion = '2.0.2.RELEASE'
}
repositories {
mavenCentral()
}
dependencies {
classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
}
}
apply plugin: 'java'
apply plugin: 'idea'
apply plugin: 'org.springframework.boot'
apply plugin: 'io.spring.dependency-management'
group = 'louie.share'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = 1.8
targetCompatibility = 1.8
repositories {
mavenCentral()
}
dependencies {
compile('org.springframework.boot:spring-boot-starter-data-jpa')
compile('org.springframework.boot:spring-boot-starter-web')
runtime('org.springframework.boot:spring-boot-devtools')
runtime('org.postgresql:postgresql')
testCompile('org.springframework.boot:spring-boot-starter-test')
}
4、application.yml配置数据库及jpa
spring:
datasource:
driver-class-name: org.postgresql.Driver
url: jdbc:postgresql://127.0.0.1:5432/louie
data-username: louie
password: louie1234
jpa:
database: postgresql
hibernate:
ddl-auto: update
二、用户管理
1、创建User实体类
import org.hibernate.annotations.GenericGenerator;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.Table;
import java.io.Serializable;
/**
* 用户实体
* @author louie
* @date created in 2018-5-12 17:28
*/
@Entity
@Table(name = "b_id_user")
public class User implements Serializable{
@Id
@GenericGenerator(name = "idGenerator",strategy = "uuid")
@GeneratedValue(generator = "idGenerator")
private String id;
@NotBlank(message = "account can not be empty")
private String account;
@NotBlank(message = "password can not be empty")
private String password;
@NotBlank(message = "name can not be empty")
private String name;
//省略getter、setter
}
2、用户服务接口
import louie.share.sessionredis.bean.User;
/**
* 用户服务接口
* @author louie
* @date created in 2018-5-12 17:40
*/
public interface UserService {
/**
* save user
* @param user
* @return 保存后的用户信息
*/
User saveUser(User user);
/**
* find user by account
* @param account
* @return
*/
User findByAccount(String account);
/**
* user login
* @param account
* @param password
* @return
*/
BaseResponse login(String account,String password);
}
这里省略接口的实现,您可以访问我的github和码云查看该工程的源代码(代码地址见文档底部)。
3、用户管理控制器
import louie.share.sessionredis.bean.BaseResponse;
import louie.share.sessionredis.bean.User;
import louie.share.sessionredis.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;
/**
* 用户管理相关控制器
* @author louie
* @date created in 2018-5-12 17:26
*/
@RestController
@RequestMapping(value = "/user")
public class UserController {
@Autowired
private UserService userService;
/**
* save user
* @param user
* @return
*/
@RequestMapping(value = "/save",method = RequestMethod.POST)
public User save(User user){
return userService.saveUser(user);
}
/**
* find user by account
* @param account
* @return
*/
@RequestMapping(value = "/find/{account}",method = RequestMethod.GET)
public User find(@PathVariable String account){
return userService.findByAccount(account);
}
/**
* user login
* @param account
* @param password
* @return
*/
@RequestMapping(value = "/login",method = RequestMethod.POST)
public BaseResponse login(String account,String password){
return userService.login(account,password);
}
}
4、创建用户
运行Application类启动服务,使用postMan访问http://localhost:8080/user/save服务创建用户:
三、用户身份认证
1、使用postMan访问http://localhost:8080/user/login进行用户登录校验:
四、spring-session配置
该部分为重点内容了,目的是实现访问资源时的安全认证、超时控制和用户登出功能。
1、修改用户登录login控制,登录成功后将用户信息写入session
/**
* user login
* @param account
* @param password
* @return
*/
@RequestMapping(value = "/login",method = RequestMethod.POST)
public BaseResponse login(String account, String password,HttpSession session){
BaseResponse response = userService.login(account,password);
if (response.isOk()){
session.setAttribute(session.getId(),response.getData());
}
return response;
}
2、新增用户登出logout功能,将用户信息移除session
/**
* user logout
* @param session
* @return
*/
@RequestMapping(value = "/logout")
public String logout(HttpSession session){
session.removeAttribute(session.getId());
return "user logout success";
}
3、设置session过期时间
spring:
datasource:
driver-class-name: org.postgresql.Driver
url: jdbc:postgresql://127.0.0.1:5432/louie
data-username: louie
password: louie1234
jpa:
database: postgresql
hibernate:
ddl-auto: update
server:
servlet:
session:
timeout: "PT10M"
以下是为session有效时长为10分钟:
4、添加拦截器,通过session判断用户是否有效
import com.alibaba.fastjson.JSON;
import louie.share.sessionredis.bean.BaseResponse;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.HandlerInterceptor;
import org.springframework.web.servlet.config.annotation.InterceptorRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;
import java.io.IOException;
/**
* @author louie
* @date created in 2018-5-12 19:02
*/
@Configuration
public class SessionCofig implements WebMvcConfigurer{
@Override
public void addInterceptors(InterceptorRegistry registry) {
registry.addInterceptor(new SecurityInterceptor())
//排除拦截
.excludePathPatterns("/user/login")
.excludePathPatterns("/user/logout")
//拦截路径
.addPathPatterns("/**");
}
@Configuration
public class SecurityInterceptor implements HandlerInterceptor{
@Override
public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws IOException {
HttpSession session = request.getSession();
if (session.getAttribute(session.getId()) != null){
return true;
}
response.getWriter().write(JSON.toJSONString(
new BaseResponse(){{
setOk(false);
setMessage("please login first");
}}
));
return false;
}
}
}
5、使用postMan访问http://localhost:8080/user/find/101,用户未登录,被拦截:
访问http://localhost:8080/user/login登录:
再次访问访问http://localhost:8080/user/find/101:
五、使用redis存储session
1、添加依赖
compile('org.springframework.boot:spring-boot-starter-data-redis')
compile('org.springframework.session:spring-session-data-redis')
2、application.yml中添加配置
源代码:
spring:
datasource:
driver-class-name: org.postgresql.Driver
url: jdbc:postgresql://127.0.0.1:5432/louie
data-username: louie
password: louie1234
jpa:
database: postgresql
hibernate:
ddl-auto: update
redis:
database: 0
host: localhost
port: 6379
password: xonro_vflow
session:
store-type: redis
server:
servlet:
session:
timeout: "PT10M"
3、启动redis和application类,用户登录,查看redis内容:
debug查看:
