# spring boot 实现分布式 session
|
||||
|
||||
## 一、项目结构
|
||||
|
||||
<div align="center"> <img src="https://github.com/heibaiying/spring-samples-for-all/blob/master/pictures/spring-boot-session.png"/> </div>
|
||||
|
||||
|
||||
|
||||
## 二、分布式session的配置
|
||||
|
||||
#### 2.1 引入依赖
|
||||
|
||||
```xml
|
||||
<!--分布式 session 相关依赖-->
|
||||
<dependency>
|
||||
<groupId>org.springframework.boot</groupId>
|
||||
<artifactId>spring-boot-starter-data-redis</artifactId>
|
||||
</dependency>
|
||||
<dependency>
|
||||
<groupId>org.springframework.session</groupId>
|
||||
<artifactId>spring-session-data-redis</artifactId>
|
||||
</dependency>
|
||||
```
|
||||
|
||||
#### 2.2 Redis配置
|
||||
|
||||
```yaml
|
||||
spring:
|
||||
redis:
|
||||
host: 127.0.0.1
|
||||
port: 6379
|
||||
jedis:
|
||||
pool:
|
||||
# 连接池最大连接数,使用负值表示无限制。
|
||||
max-active: 8
|
||||
# 连接池最大阻塞等待时间,使用负值表示无限制。
|
||||
max-wait: -1s
|
||||
# 连接池最大空闲数,使用负值表示无限制。
|
||||
max-idle: 8
|
||||
# 连接池最小空闲连接，只有设置为正值时候才有效
|
||||
min-idle: 1
|
||||
timeout: 300ms
|
||||
session:
|
||||
# session 存储方式 支持redis、mongo、jdbc、hazelcast
|
||||
store-type: redis
|
||||
|
||||
# 如果是集群节点 采用如下配置指定节点
|
||||
#spring.redis.cluster.nodes
|
||||
|
||||
```
|
||||
|
||||
有两点需要特别说明：
|
||||
|
||||
1. spring-session 不仅提供了redis作为公共session存储的方案，同时也支持jdbc、mongodb、Hazelcast等作为公共session的存储，可以用session.store-type 指定；
|
||||
2. 对于redis 存储方案而言，官方也提供了不止一种整合方式，这里我们选取的整合方案是jedis客户端作为连接，当然也可以使用Lettuce作为客户端连接。
|
||||
|
||||
#### 2.3 启动类上添加@EnableRedisHttpSession 注解开启 spring-session-redis 整合方案的自动配置
|
||||
|
||||
```java
|
||||
@SpringBootApplication
|
||||
@EnableRedisHttpSession(maxInactiveIntervalInSeconds= 1800) //开启redis session支持,并配置session过期时间
|
||||
public class SpringBootSessionApplication {
|
||||
|
||||
public static void main(String[] args) {
|
||||
SpringApplication.run(SpringBootSessionApplication.class, args);
|
||||
}
|
||||
|
||||
}
|
||||
```
|
||||
|
||||
|
||||
|
||||
## 三、验证分布式session
|
||||
|
||||
#### 3.1 创建测试controller和测试页面
|
||||
|
||||
```java
|
||||
@Controller
|
||||
public class LoginController {
|
||||
|
||||
@RequestMapping
|
||||
public String index() {
|
||||
return "index";
|
||||
}
|
||||
|
||||
@RequestMapping("home")
|
||||
public String home() {
|
||||
return "home";
|
||||
}
|
||||
|
||||
@PostMapping("login")
|
||||
public String login(User user, HttpSession session) {
|
||||
// 随机生成用户id
|
||||
user.setUserId(Math.round(Math.floor(Math.random() * 10 * 1000)));
|
||||
// 将用户信息保存到id中
|
||||
session.setAttribute("USER", user);
|
||||
return "home";
|
||||
}
|
||||
|
||||
}
|
||||
```
|
||||
|
||||
登录页面index.ftl：
|
||||
|
||||
```jsp
|
||||
<!doctype html>
|
||||
<html lang="en">
|
||||
<head>
|
||||
<title>登录页面</title>
|
||||
</head>
|
||||
<body>
|
||||
<form action="/login" method="post">
|
||||
用户：<input type="text" name="username"><br/>
|
||||
密码：<input type="password" name="password"><br/>
|
||||
<button type="submit">登录</button>
|
||||
</form>
|
||||
</body>
|
||||
</html>
|
||||
```
|
||||
|
||||
session 信息展示页面home.ftl：
|
||||
|
||||
```jsp
|
||||
<!doctype html>
|
||||
<html lang="en">
|
||||
<head>
|
||||
<title>主页面</title>
|
||||
</head>
|
||||
<body>
|
||||
<h5>登录用户: ${Session["USER"].username} </h5>
|
||||
<h5>用户编号: ${Session["USER"].userId} </h5>
|
||||
</body>
|
||||
</html>
|
||||
```
|
||||
|
||||
#### 3.2 启动项目
|
||||
|
||||
由于我们这里采用的是spring boot 的内置容器作为web容器，所以直接启动两个实例测试即可。
|
||||
|
||||
应用1启动配置：
|
||||
|
||||
<div align="center"> <img src="https://github.com/heibaiying/spring-samples-for-all/blob/master/pictures/spring-boot-session-app1.png"/> </div>
|
||||
|
||||
应用2启动配置，需要用 `--server.port `指定不同的端口号：
|
||||
|
||||
<div align="center"> <img src="https://github.com/heibaiying/spring-samples-for-all/blob/master/pictures/spring-boot-session-app2.png"/> </div>
|
||||

# spring session 实现分布式 session
|
||||
|
||||
## 一、项目结构
|
||||
|
||||
分布式session 主要配置文件为spring-session.xml和web.xml，其他的配置为标准的web工程的配置。
|
||||
|
||||
<div align="center"> <img src="https://github.com/heibaiying/spring-samples-for-all/blob/master/pictures/spring-session.png"/> </div>
|
||||
|
||||
## 二、分布式session的配置
|
||||
|
||||
#### 2.1 引入依赖
|
||||
|
||||
```xml
|
||||
<!--分布式 session 相关依赖-->
|
||||
<dependency>
|
||||
<groupId>org.springframework.data</groupId>
|
||||
<artifactId>spring-data-redis</artifactId>
|
||||
<version>2.1.3.RELEASE</version>
|
||||
</dependency>
|
||||
<dependency>
|
||||
<groupId>redis.clients</groupId>
|
||||
<artifactId>jedis</artifactId>
|
||||
<version>2.9.0</version>
|
||||
</dependency>
|
||||
<dependency>
|
||||
<groupId>org.springframework.session</groupId>
|
||||
<artifactId>spring-session-data-redis</artifactId>
|
||||
<version>2.1.3.RELEASE</version>
|
||||
</dependency>
|
||||
```
|
||||
|
||||
#### 2.2 在web.xml中配置session拦截器
|
||||
|
||||
```xml
|
||||
<!--配置http session-->
|
||||
<filter>
|
||||
<filter-name>springSessionRepositoryFilter</filter-name>
|
||||
<filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
|
||||
</filter>
|
||||
<filter-mapping>
|
||||
<filter-name>springSessionRepositoryFilter</filter-name>
|
||||
<url-pattern>/*</url-pattern>
|
||||
</filter-mapping>
|
||||
|
||||
```
|
||||
|
||||
#### 2.3 创建配置文件spring- session.xml，配置redis连接
|
||||
|
||||
有两点需要特别说明：
|
||||
|
||||
1. spring-session 不仅提供了redis作为公共session存储的方案，同时也支持jdbc、mongodb、Hazelcast等作为公共session的存储；
|
||||
2. 对于redis 存储方案而言，官方也提供了不止一种整合方式，这里我们选取的整合方案是jedis客户端作为连接，当然也可以使用Lettuce作为客户端连接。

|
||||
```
|
||||
|
||||
## 三、验证分布式session
|
||||
|
||||
#### 3.1 创建测试controller和测试页面
|
||||
|
||||
```java
|
||||
@Controller
|
||||
public class LoginController {
|
||||
|
||||
@RequestMapping
|
||||
public String index(){
|
||||
return "index";
|
||||
}
|
||||
|
||||
@RequestMapping("home")
|
||||
public String home(){
|
||||
return "home";
|
||||
}
|
||||
|
||||
@PostMapping("login")
|
||||
public String login(User user, HttpSession session, HttpServletRequest request, Model model){
|
||||
// 随机生成用户id
|
||||
user.setUserId(Math.round(Math.floor(Math.random() *10*1000)));
|
||||
// 将用户信息保存到id中
|
||||
session.setAttribute("USER",user);
|
||||
return "redirect:home";
|
||||
}
|
||||
|
||||
}
|
||||
```
|
||||
|
||||
登录页面：
|
||||
|
||||
```jsp
|
||||
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
|
||||
<html>
|
||||
<head>
|
||||
<title>登录页面</title>
|
||||
</head>
|
||||
<body>
|
||||
<h5>服务器:<%=request.getServerName()+":"+request.getServerPort()%></h5>
|
||||
<form action="${pageContext.request.contextPath}/login" method="post">
|
||||
用户：<input type="text" name="username"><br/>
|
||||
密码：<input type="password" name="password"><br/>
|
||||
<button type="submit">登录</button>
|
||||
</form>
|
||||
</body>
|
||||
</html>
|
||||
```
|
||||
|
||||
session 信息展示页面(home.jsp)：
|
||||
|
||||
```jsp
|
||||
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
|
||||
<html>
|
||||
<head>
|
||||
<title>主页面</title>
|
||||
</head>
|
||||
<body>
|
||||
<h5>服务器:<%=request.getServerName()+":"+request.getServerPort()%></h5>
|
||||
<h5>登录用户: ${sessionScope.USER.username} </h5>
|
||||
<h5>用户编号: ${sessionScope.USER.userId} </h5>
|
||||
</body>
|
||||
</html>
|
||||
```
|
||||
|
||||
#### 3.2 启动项目
|
||||
|
||||
这里我们采用两个tomcat分别启动项目，在第一个项目index.jsp页面进行登录，第二个项目不登录，直接访问session展示页（home.jsp）
|
||||
|
||||
tomcat 1 配置：

## 一、项目结构
|
||||
|
||||
分布式session 主要配置文件为spring-session.xml和web.xml，其他的配置为标准的web工程的配置。
|
||||

|
||||
|
||||
## 二、分布式session的配置
|
||||
|
||||
#### 2.1 引入依赖
|
||||
|
||||
```xml
|
||||
<!--分布式 session 相关依赖-->
|
||||
<dependency>
|
||||
<groupId>org.springframework.data</groupId>
|
||||
<artifactId>spring-data-redis</artifactId>
|
||||
<version>2.1.3.RELEASE</version>
|
||||
</dependency>
|
||||
<dependency>
|
||||
<groupId>redis.clients</groupId>
|
||||
<artifactId>jedis</artifactId>
|
||||
<version>2.9.0</version>
|
||||
</dependency>
|
||||
<dependency>
|
||||
<groupId>org.springframework.session</groupId>
|
||||
<artifactId>spring-session-data-redis</artifactId>
|
||||
<version>2.1.3.RELEASE</version>
|
||||
</dependency>
|
||||
```
|
||||
|
||||
#### 2.2 在web.xml中配置session拦截器
|
||||
|
||||
```xml
|
||||
<!--配置http session-->
|
||||
<filter>
|
||||
<filter-name>springSessionRepositoryFilter</filter-name>
|
||||
<filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
|
||||
</filter>
|
||||
<filter-mapping>
|
||||
<filter-name>springSessionRepositoryFilter</filter-name>
|
||||
<url-pattern>/*</url-pattern>
|
||||
</filter-mapping>
|
||||
|
||||
```
|
||||
|
||||
#### 2.3 创建配置文件spring- session.xml，配置redis连接
|
||||
|
||||
有两点需要特别说明：
|
||||
|
||||
1. spring-session 不仅提供了redis作为公共session存储的方案，同时也支持jdbc、mongodb、Hazelcast等作为公共session的存储；
|
||||
2. 对于redis 存储方案而言，官方也提供了不止一种整合方式，这里我们选取的整合方案是jedis客户端作为连接，当然也可以使用Lettuce作为客户端连接。

|
||||
|
||||
</beans>
|
||||
```
|
||||
|
||||
## 三、验证分布式session
|
||||
|
||||
#### 3.1 创建测试controller和测试页面
|
||||
|
||||
```java
|
||||
@Controller
|
||||
public class LoginController {
|
||||
|
||||
@RequestMapping
|
||||
public String index(){
|
||||
return "index";
|
||||
}
|
||||
|
||||
@RequestMapping("home")
|
||||
public String home(){
|
||||
return "home";
|
||||
}
|
||||
|
||||
@PostMapping("login")
|
||||
public String login(User user, HttpSession session, HttpServletRequest request, Model model){
|
||||
// 随机生成用户id
|
||||
user.setUserId(Math.round(Math.floor(Math.random() *10*1000)));
|
||||
// 将用户信息保存到id中
|
||||
session.setAttribute("USER",user);
|
||||
return "redirect:home";
|
||||
}
|
||||
|
||||
}
|
||||
```
|
||||
|
||||
登录页面：
|
||||
|
||||
```jsp
|
||||
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
|
||||
<html>
|
||||
<head>
|
||||
<title>登录页面</title>
|
||||
</head>
|
||||
<body>
|
||||
<h5>服务器:<%=request.getServerName()+":"+request.getServerPort()%></h5>
|
||||
<form action="${pageContext.request.contextPath}/login" method="post">
|
||||
用户：<input type="text" name="username"><br/>
|
||||
密码：<input type="password" name="password"><br/>
|
||||
<button type="submit">登录</button>
|
||||
</form>
|
||||
</body>
|
||||
</html>
|
||||
```
|
||||
|
||||
session 信息展示页面(home.jsp)：
|
||||
|
||||
```jsp
|
||||
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
|
||||
<html>
|
||||
<head>
|
||||
<title>主页面</title>
|
||||
</head>
|
||||
<body>
|
||||
<h5>服务器:<%=request.getServerName()+":"+request.getServerPort()%></h5>
|
||||
<h5>登录用户: ${sessionScope.USER.username} </h5>
|
||||
<h5>用户编号: ${sessionScope.USER.userId} </h5>
|
||||
</body>
|
||||
</html>
|
||||
```
|
||||
|
||||
#### 3.2 启动项目
|
||||
|
||||
这里我们采用两个tomcat分别启动项目，在第一个项目index.jsp页面进行登录，第二个项目不登录，直接访问session展示页（home.jsp）
|
||||
|
||||
tomcat 1 配置：
|
||||
|
||||
<div align="center"> <img src="https://github.com/heibaiying/spring-samples-for-all/blob/master/pictures/spring-session-tomcat01.png"/> </div>
|
||||
|

||||
|
||||
