springboot集成spring session实现session共享

首先pom.xml引入依赖

<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>

控制器里写方法：

@RestController @RequestMapping(value = "/api/user") public class LoginController { @RequestMapping(value = "/showPort") public String showPort (HttpServletRequest request) { return request.getLocalPort() + ""; } @RequestMapping(value = "/saveSession") public String saveSession (HttpServletRequest request) { request.getSession().setAttribute("userName", "admin"); return request.getLocalPort() + "—" + request.getSession().getId(); } @RequestMapping(value = "/getSession") public String getSession (HttpServletRequest request) { String userName = (String) request.getSession().getAttribute("userName"); return request.getLocalPort() + "userName：" + userName; } }

然后把项目复制出来一份，改个名，修改application.properties配置，两个不同端口

server.port=9999 server.port=9998

配置nginx负载均衡，启动nginx

upstream transformers { server 127.0.0.1:9999; server 127.0.0.1:9998; } server { listen 80; server_name localhost; location / { proxy_pass http://transformers; } }

然后是很关键的一步：启动你的两个项目，看下运行效果

用9998端口存session，9999端口获取session
