SpringBoot+MyBatis+Redis实现SSO单点登录系统(二)
三、代码
配置文件配置数据库，redis等相关的信息。
# See http://docs.spring.io/spring-boot/docs/current/reference/html/common-application-properties.html
# Thymeleaf配置
spring.thymeleaf.cache=false
spring.thymeleaf.mode=HTML
spring.main.show-banner=false
spring.thymeleaf.prefix=classpath:/templates
spring.thymeleaf.suffix=.html
logging.level.jdbc=OFF
logging.level.jdbc.sqltiming=DEBUG
logging.level.jdbc.resultsettable=DEBUG
# 数据库配置
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://127.0.0.1:3306/taotao?useSSL=false
spring.datasource.username=root
spring.datasource.password=root
# 日志配置
logging.config=classpath:logback-spring.xml
logging.level.root=info
# MyBatis配置
mybatis.type-aliases-package=cn.hzr0523.entity
mybatis.mapper-locations=classpath:mapper/*.xml
#Redis Cluster
spring.redis.host=127.0.0.1
spring.redis.port=6379
spring.redis.password=123456
spring.redis.maxTotal=30
USER_SESSION_KEY=REDIS_USER_SESSION
SSO_SESSION_EXPIRE=30接着，是jedisConfig的配置，采用java配置方式，取代了xml配置，也是Spring Boot推荐的一种配置方式。
package cn.hzr0523.service.impl;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import redis.clients.jedis.JedisPool;
import redis.clients.jedis.JedisPoolConfig;
@Configuration
public class JedisConfig {
@Value("${spring.redis.maxTotal}")
public Integer maxTotal;
@Value("${spring.redis.host}")
public String host;
@Value("${spring.redis.port}")
public Integer port;
@Value("${spring.redis.password}")
public String password;
@Bean
public JedisPoolConfig jedisPoolConfig() {
JedisPoolConfig jedisPoolConfig = new JedisPoolConfig();
jedisPoolConfig.setMaxTotal(maxTotal);
return jedisPoolConfig;
}
@Bean
public JedisPool jedisPool() {
JedisPool jedisPool = new JedisPool(jedisPoolConfig(), host, port, 30, password);
return jedisPool;
}
}
接下来jedis工具类的编码：
package cn.hzr0523.service;
public interface JedisClient {
String get(String key);
String set(String key, String value);
String hget(String hkey, String key);
long hset(String hkey, String key, String value);
long incr(String key);
long expire(String key, int second);
long ttl(String key);
long del(String key);
long hdel(String hkey, String key);
}
package cn.hzr0523.service.impl;
import cn.hzr0523.service.JedisClient;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import org.springframework.stereotype.Service;
import redis.clients.jedis.Jedis;
import redis.clients.jedis.JedisPool;
/**
* 单个redis
*/
@Service
public class JedisClientSingle implements JedisClient {
@Autowired
private JedisPool jedisPool;
@Override
public String get(String key) {
Jedis jedis = jedisPool.getResource();
String string = jedis.get(key);
jedis.close();
return string;
}
@Override
public String set(String key, String value) {
Jedis jedis = jedisPool.getResource();
String string = jedis.set(key, value);
jedis.close();
return string;
}
@Override
public String hget(String hkey, String key) {
Jedis jedis = jedisPool.getResource();
String string = jedis.hget(hkey, key);
jedis.close();
return string;
}
@Override
public long hset(String hkey, String key, String value) {
Jedis jedis = jedisPool.getResource();
Long result = jedis.hset(hkey, key, value);
jedis.close();
return result;
}
@Override
public long incr(String key) {
Jedis jedis = jedisPool.getResource();
Long result = jedis.incr(key);
jedis.close();
return result;
}
@Override
public long expire(String key, int second) {
Jedis jedis = jedisPool.getResource();
Long result = jedis.expire(key, second);
jedis.close();
return result;
}
@Override
public long ttl(String key) {
Jedis jedis = jedisPool.getResource();
Long result = jedis.ttl(key);
jedis.close();
return result;
}
@Override
public long del(String key) {
Jedis jedis = jedisPool.getResource();
Long result = jedis.del(key);
jedis.close();
return result;
}
@Override
public long hdel(String hkey, String key) {
Jedis jedis = jedisPool.getResource();
Long result = jedis.hdel(hkey, key);
jedis.close();
return result;
}
}
接下来就可以使用redis了
public ResultObject userLogin(UserDTO userDTO, HttpServletRequest request, HttpServletResponse response) {
ResultObject resultObject = new ResultObject();
if (userDTO == null) {
resultObject.setResultCode("0");
resultObject.setResultMessage("参数错误");
return resultObject;
}
//根据登录信息查询学员信息
TbUser user = userMapper.getUserInfo(userDTO.getUserName(), userDTO.getPassword());
if (user == null) {
resultObject.setResultCode("0");
resultObject.setResultMessage("用户名或密码错误");
return resultObject;
}
//登录成功，把用户信息写入redis
//String s = jedisClientSingle.get(USER_SESSION_KEY);
//logger.info("USER_SESSION_KEY: " + s);
//生成一个用户token
String token = UUID.randomUUID().toString();
logger.info(JSONObject.toJSONString(user));
jedisClient.set(USER_SESSION_KEY + ":" + token, JSONObject.toJSONString(user));
//设置session过期时间
jedisClient.expire(USER_SESSION_KEY + ":" + token, SSO_SESSION_EXPIRE);
//添加写cookie的逻辑，cookie的有效期是关闭浏览器就失效。
CookieUtils.setCookie(response, "TT_TOKEN", token, -1);
//返回token
resultObject.setResultCode("1");
resultObject.setResultMessage("登录成功");
resultObject.setResultData(token);
return resultObject;
}简单小demo，也是参考别人写的，在编写过程中也遇到了一些问题，包括redis的安装，jedis的使用。有错才能成长，大家一起进步。
