高并并发架构：

nginx+tomcat集群+Redis+ActiveMQ

redis缓存案例如下：

test代码：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations={"classpath:spring/applicationContext.xml"})
public class UserDaoRedisTest {
   
        @Autowired
        private UserServiceRedis userServiceRedis;
       
        @Test 
        public void testCrud() { 
            // -------------- Create --------------- 
           
           
            String uid = "u123456"; 
            String address1 = "上海"; 
            User_Redis user = new User_Redis(); 
            user.setAddress(address1); 
            user.setUid(uid); 
            userServiceRedis.save(user);
           
            System.out.println("执行save....");
     
            // ---------------Read --------------- 
            user = userServiceRedis.read(uid); 
               
            assertEquals(address1, user.getAddress());
            System.out.println("执行read...."+user.getAddress()+user.getUid());
     
            // --------------Update ------------ 
            String address2 = "北京"; 
            user.setAddress(address2); 
            userServiceRedis.save(user); 
     
            user = userServiceRedis.read(uid); 
     
            assertEquals(address2, user.getAddress()); 
     
            // --------------Delete ------------ 
            userServiceRedis.delete(uid); 
            System.out.println("执行delete....");
            user = userServiceRedis.read(uid); 
            assertNull(user); 
        } 
}

 

RedisDao：

@Repository
public class UserDaoImplRedis implements UserDaoRedis {

    @Autowired 
    private RedisTemplate redisTemplate;
   
    @Override
    public void save(final User_Redis user) {
        redisTemplate.execute(new RedisCallback
