之前说了单点登录系统的原理，这篇就来点硬货，说下单点登录的一个系统是如何搭建的。
架构分析
表现层：提供手机客户端，或其他系统的调用
表现层的存在意义就是，提供给所有非本系统的其他系统进行登录。具体实现的思路就是，编写一个登录的接口（本系统使用RESTful风格的），让需要该服务的其他系统通过接口提交数据，并获得相应的返回。
服务层：系统内部的调用
这个比较简单了，内部的所有登录，查询的操作都是通过服务层去实现的。
我们本次的搭建使用maven实现的，如果使用其他技术，请自行从网上查找其他资料
服务层
首先是我们的服务层，我们的服务层中总共只有三个子项目：分别是聚合工程的父工程（taotao-sso）还有就是两个子工程，负责提供接口和依赖的接口工程（taotao-sso-interface）和负责真正的业务处理的业务处理工程（taotao-sso-service）。跟其他聚合工程的的服务层相比，它的里面是没有实体层（pojo）和持久层（mapper）的。因为项目中一般所有的数据库表都是有一个专门的团队去维护的（数据库开发工程师），目的是保证数据的安全性、读取速度等。所以对应的实体层（pojo）和持久层（mapper）的编写一般也都是由他们来进行完成的。
而我们的单点登录系统肯定是要使用实体和持久层的，这个时候，我们需要依赖后台的pojo和mapper就可以了。
表现层
表现层主要提供接口给别的系统用，就是一个普通的表现层web工程。
搭建
搭建taotao-sso
创建工程
创建聚合工程父工程
创建聚合工程子工程-interface
创建聚合工程子工程-service
加入依赖（就是pom.xml文件中的代码）
这里依赖的那个parent的包下的xml文件也一并提供下，建工程的过程就不写了，参见taotao-sso

对了，还需要引入之前的redis中写的工具类的包。其实大家可以试着自己写一下，很简单的不过我还是提供下代码：建立的包结构如下：
JedisClusterUtiles.java
1 package com.taotao.manager.redis.impl; 2 3 import org.springframework.beans.factory.annotation.Autowired; 4 5 import com.taotao.manager.redis.RedisUtils; 6 7 import redis.clients.jedis.JedisCluster; 8 9 /** 10 * 集群版redis 11 * @author Administrator 12 * 13 */ 14 public class RedisCluster implements RedisUtils { 15 16 @Autowired 17 private JedisCluster jedisCluster; 18 19 @Override 20 public void set(String key, String value) { 21 this.jedisCluster.set(key, value); 22 } 23 24 @Override 25 public String get(String key) { 26 String result = this.jedisCluster.get(key); 27 return result; 28 } 29 30 @Override 31 public void del(String key) { 32 this.jedisCluster.del(key); 33 } 34 35 @Override 36 public void expire(String key, Integer seconds) { 37 this.jedisCluster.expire(key, seconds); 38 } 39 40 @Override 41 public void set(String key, String value, Integer seconds) { 42 this.jedisCluster.set(key, value); 43 this.jedisCluster.expire(key, seconds); 44 } 45 46 @Override 47 public Long incr(String key) { 48 Long count = this.jedisCluster.incr(key); 49 return count; 50 } 51 }
JedisPoolUtils.java
1 package com.taotao.manager.redis.impl; 2 3 import org.springframework.beans.factory.annotation.Autowired; 4 5 import com.taotao.manager.redis.RedisUtils; 6 7 import redis.clients.jedis.Jedis; 8 import redis.clients.jedis.JedisPool; 9 10 /** 11 * 单机版redis实现 12 * @author Administrator 13 * 14 */ 15 public class RedisPool implements RedisUtils { 16 17 @Autowired 18 private JedisPool jedisPool; 19 20 @Override 21 public void set(String key, String value) { 22 Jedis jedis = this.jedisPool.getResource(); 23 24 jedis.set(key, value); 25 jedis.close(); 26 } 27 28 @Override 29 public String get(String key) { 30 Jedis jedis = this.jedisPool.getResource(); 31 32 String result = jedis.get(key); 33 jedis.close(); 34 35 return result; 36 } 37 38 @Override 39 public void del(String key) { 40 Jedis jedis = this.jedisPool.getResource(); 41 42 jedis.del(key); 43 jedis.close(); 44 45 } 46 47 @Override 48 public void expire(String key, Integer seconds) { 49 Jedis jedis = this.jedisPool.getResource(); 50 51 jedis.expire(key, seconds); 52 jedis.close(); 53 54 } 55 56 @Override 57 public void set(String key, String value, Integer seconds) { 58 Jedis jedis = this.jedisPool.getResource(); 59 60 jedis.set(key, value); 61 jedis.expire(key, seconds); 62 jedis.close(); 63 64 } 65 66 @Override 67 public Long incr(String key) { 68 Jedis jedis = this.jedisPool.getResource(); 69 70 Long count = jedis.incr(key); 71 jedis.close(); 72 73 return count; 74 } 75 }
RedisUtils.java
1 package com.taotao.manager.redis; 2 public interface RedisUtils{ 3 /** 4 * 保存 5 * 6 * @param key 7 * @param value 8 */ 9 public void set(String key, String value); 10 11 /** 12 * 根据key查询 13 * 14 * @param key 15 * @return 16 */ 17 public String get(String key); 18 19 /** 20 * 删除 21 * 22 * @param key 23 */ 24 public void del(String key); 25 26 /** 27 * 根据key设置生存时间 28 * 29 * @param key 30 * @param seconds 31 */ 32 public void expire(String key, Integer seconds); 33 34 /** 35 * 保存并设置生存时间 36 * 37 * @param key 38 * @param value 39 * @param seconds 40 */ 41 public void set(String key, String value, Integer seconds); 42 43 /** 44 * value加一 45 * 46 * @param key 47 * @return 48 */ 49 public Long incr(String key); 50 51 }
