#spring.redis.password=
spring.redis.pool.max-active=8
spring.redis.pool.max-wait=30
spring.redis.pool.max-idle=8
spring.redis.pool.min-idle=0
spring.redis.timeout=10

spring.session.store-type=redis

11.19.1.3. Application

				package cn.netkiller;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.data.jpa.repository.config.EnableJpaRepositories;
import org.springframework.data.mongodb.repository.config.EnableMongoRepositories;
import org.springframework.scheduling.annotation.EnableScheduling;
import org.springframework.session.data.redis.config.annotation.web.http.EnableRedisHttpSession;

@SpringBootApplication
@EnableAutoConfiguration
@ComponentScan
@EnableMongoRepositories
@EnableJpaRepositories
@EnableScheduling
public class Application {

	public static void main(String[] args) {
		SpringApplication.run(Application.class, args);

	}
}

RedisHttpSessionConfig.java

				package cn.netkiller.config;

import org.springframework.context.annotation.Configuration;
import org.springframework.session.data.redis.config.annotation.web.http.EnableRedisHttpSession;

@Configuration
@EnableRedisHttpSession
public class RedisHttpSessionConfig {

	public RedisHttpSessionConfig() {
		// TODO Auto-generated constructor stub
	}

}

11.19.2. 测试 Session

			package cn.netkiller.web;

import java.util.Date;

import javax.servlet.http.HttpSession;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

@Controller
public class TestController {

	public TestController() {
		// TODO Auto-generated constructor stub
	}

	@RequestMapping("/session/set")
	@ResponseBody
	public String set(HttpSession session) {
		String key = "test";
		session.setAttribute(key, new Date());
		return key;
	}

	@RequestMapping("/session/get")
	@ResponseBody
	public String get(HttpSession session) {
		String value = (String) session.getAttribute("test").toString();
		return value;
