Redis的Session配置类RedisSessionManagerConfiguration,主要是实现JSON格式的系列化

package com.smartmap.sample.test.conf;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.redis.serializer.GenericJackson2JsonRedisSerializer;
import org.springframework.data.redis.serializer.RedisSerializer; @Configuration
public class RedisSessionManagerConfiguration {
// 设置Session的系列化为JSON格式
@Bean(name = "springSessionDefaultRedisSerializer")
public RedisSerializer<?> getRedisSerializer() {
return new GenericJackson2JsonRedisSerializer();
}
}

RedisTemplate的配置

package com.smartmap.sample.test.conf;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.redis.connection.RedisConnectionFactory;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.serializer.GenericJackson2JsonRedisSerializer;
import org.springframework.data.redis.serializer.RedisSerializer;
import org.springframework.data.redis.serializer.StringRedisSerializer; @Configuration
public class RedisConfiguration { @Bean
public RedisTemplate<String, Object> stringJsonRedisTemplate(RedisConnectionFactory redisConnectionFactory) {
RedisTemplate<String, Object> template = new RedisTemplate<String, Object>();
template.setConnectionFactory(redisConnectionFactory);
template.setDefaultSerializer(new GenericJackson2JsonRedisSerializer());
RedisSerializer<String> stringSerializer = new StringRedisSerializer();
template.setKeySerializer(stringSerializer);
template.setHashKeySerializer(stringSerializer);
return template;
} }

Redis缓存配置RedisCacheManagerCustomizer

package com.smartmap.sample.test.conf;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.redis.cache.RedisCacheConfiguration;
import org.springframework.data.redis.cache.RedisCacheManager;
import org.springframework.data.redis.cache.RedisCacheManager.RedisCacheManagerBuilder;
import org.springframework.data.redis.connection.RedisConnectionFactory;
import org.springframework.data.redis.serializer.GenericJackson2JsonRedisSerializer;
import org.springframework.data.redis.serializer.Jackson2JsonRedisSerializer;
import org.springframework.data.redis.serializer.RedisSerializationContext;
import org.springframework.data.redis.serializer.RedisSerializationContext.SerializationPair;
import org.springframework.data.redis.serializer.RedisSerializer;
import org.springframework.data.redis.serializer.StringRedisSerializer; import com.fasterxml.jackson.annotation.JsonAutoDetect;
import com.fasterxml.jackson.annotation.PropertyAccessor;
import com.fasterxml.jackson.databind.ObjectMapper; @Configuration
public class RedisCacheManagerCustomizer { @Value("${spring.cache.redis.key-prefix}")
private String keyPrefix; @Bean
public RedisCacheConfiguration redisCacheConfiguration() {
GenericJackson2JsonRedisSerializer genericJackson2JsonRedisSerializer = new GenericJackson2JsonRedisSerializer();
return RedisCacheConfiguration.defaultCacheConfig()
.serializeKeysWith(
RedisSerializationContext.SerializationPair.fromSerializer(new StringRedisSerializer()))
.serializeValuesWith(
RedisSerializationContext.SerializationPair.fromSerializer(genericJackson2JsonRedisSerializer))
.prefixKeysWith(keyPrefix);
} /*@Bean
public RedisCacheManager getRedisCacheManager(RedisConnectionFactory connectionFactory) { RedisCacheManagerBuilder redisCacheManagerBuilder = RedisCacheManagerBuilder.fromConnectionFactory(connectionFactory);
RedisCacheConfiguration redisCacheConfiguration = RedisCacheConfiguration.defaultCacheConfig();
// Key
RedisSerializer<String> redisSerializerKey = new StringRedisSerializer();
SerializationPair<String> serializationPairKey = SerializationPair.fromSerializer(redisSerializerKey);
// Value
ObjectMapper objectMapper = new ObjectMapper();
objectMapper.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
objectMapper.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);
Jackson2JsonRedisSerializer<Object> jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer<Object>(
Object.class);
jackson2JsonRedisSerializer.setObjectMapper(objectMapper);
//
GenericJackson2JsonRedisSerializer genericJackson2JsonRedisSerializer = new GenericJackson2JsonRedisSerializer(
objectMapper);
//RedisSerializer<Object> redisSerializerValue = jackson2JsonRedisSerializer;
//

//

//RedisSerializationContext.SerializationPair<Object> serializationPairValue = RedisSerializationContext.SerializationPair.fromSerializer(redisSerializerValue); //
redisCacheConfiguration.serializeKeysWith(serializationPairKey);
redisCacheConfiguration.serializeValuesWith(serializationPairValue);
redisCacheManagerBuilder.cacheDefaults(redisCacheConfiguration);
RedisCacheManager redisCacheManager = redisCacheManagerBuilder.build(); //
return redisCacheManager;
}*/ }

缓存测试的Controller

package com.smartmap.sample.test.controller.rest;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpSession; import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController; import com.smartmap.sample.test.entity.User; @RestController
@RequestMapping("/api/v1.1/system/session")
public class SessionController {
final Log log = LogFactory.getLog(SessionController.class); @Autowired
RedisTemplate<String, Object> redisTemplate; /**

*/
@PostMapping("/addSessionInfo")
public User putSession(HttpServletRequest request, @RequestBody User user ){
HttpSession session = request.getSession();
log.info(session.getClass());
log.info(session.getId());
session.setAttribute("user", user);
redisTemplate.opsForValue().set("spring:manager:user", user);
return user;
} /**

*/
@GetMapping("/addSessionInfo/{userId}/{name}")
public User putSession(HttpServletRequest request, @PathVariable("userId") Long userId, @PathVariable("name") String name){
HttpSession session = request.getSession();
User user = new User();
user.setId(userId);
user.setName(name);
log.info(session.getClass());
log.info(session.getId());
session.setAttribute("user", user);
redisTemplate.opsForValue().set("spring:manager:user", user);
return user;
} /**

*/
@GetMapping("/getSessionInfo")
public User getSession(HttpServletRequest request, @RequestParam("userId") String userId){
log.info(request.getRemoteAddr());
HttpSession session = request.getSession();
User user = (User)session.getAttribute("user");
User userOther = (User)redisTemplate.opsForValue().get("spring:manager:user");
log.info(userOther.getName());
return user;
} }

启动两个应用

java -jar test.session-0.1.0.jar –-server.port=9000

java -jar test.session-0.1.0.jar –-server.port=9001

配置前端的Nginx来作为反向代理

upstream backend {
server 127.0.0.1:9000;
server 127.0.0.1:9001;
} server {
listen 80;
server_name localhost; #charset koi8-r; #access_log logs/host.access.log main;
location / {
proxy_pass http://backend;
index index.html index.htm;

# root D:/Project;

#
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
} # proxy the PHP scripts to Apache listening on 127.0.0.1:80
#
#location ~ \.php$ {
# proxy_pass http://127.0.0.1;
#} # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
#

# fastcgi_pass 127.0.0.1:9000;
# fastcgi_index index.php;
# fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name;
# include fastcgi_params;
#} # deny access to .htaccess files, if Apache's document root
# concurs with nginx's one
#
#location ~ /\.ht {
