今天完成的事情：

完成memcache代码编写和测试

   applicationContext.xml中配置

<!--定义XMemcachedClientBuilder实例-->
<bean id="memcachedClientBuilder" class="net.rubyeye.xmemcached.XMemcachedClientBuilder">
    <constructor-arg name="addressList" value="localhost:11211">
    </constructor-arg>
    <!--连接超时-->
    <property name="connectTimeout"><value>3000</value></property>
    <!--SASL验证开启 ,如果没有相关环境,请关闭 start-->
    <property name="authInfoMap"><map> <entry key-ref="server1">
        <bean class="net.rubyeye.xmemcached.auth.AuthInfo" factory-method="plain">
        <constructor-arg name="username"><value>xxx</value></constructor-arg>
        <constructor-arg name="password"><value>123</value></constructor-arg>
         </bean></entry></map></property>
    <!--SASL验证开启 end--> <!--设置线程池-->
    <property name="connectionPoolSize" value="2"></property>
    <!--使用二进制协议-->
    <property name="commandFactory">
    <bean class="net.rubyeye.xmemcached.command.BinaryCommandFactory"></bean></property>
    <!--设置序列化方式-->
    <property name="transcoder">
    <bean class="net.rubyeye.xmemcached.transcoders.SerializingTranscoder"></bean></property>
    <!--设置一致性哈希--> <property name="sessionLocator">
    <bean class="net.rubyeye.xmemcached.impl.KetamaMemcachedSessionLocator"></bean> </property></bean>
<!--定义memcachedClient，通过memcachedClientBuilder的build方法-->
<bean name="memcachedClient" factory-bean="memcachedClientBuilder" factory-method="build" destroy-method="shutdown">
</bean>

memcache代码书写

/**
 * ??????
 *
 * @param
 * @param model
 * @return
 */
@RequestMapping("/students")
public String getAllStu(Model model) throws InterruptedException, MemcachedException, TimeoutException {
    if (memcachedClient.get("students") == null) {
        List<Student> students = stu.getGetAll();
        memcachedClient.set("students", 10 * 60 * 1000, students);
    }
        System.out.println("123:" + memcachedClient.get("students"));
        List<Student> students1 = memcachedClient.get("students");
        Iterator<Student> s = students1.iterator();
        while (s.hasNext()) {

            System.out.println("这些人是：" + s.next().toString());

        }
    model.addAttribute("studentList", students1);

    return "all";

}
/**
 * ??????json
 *
 * @param
 * @param model
 * @return
 */
@RequestMapping("/json/students")
public String getAllStuOne(Model model) throws InterruptedException, MemcachedException, TimeoutException {

    if (memcachedClient.get("students") == null) {
        List<Student> students = stu.getGetAll();
        memcachedClient.set("students", 10 * 60 * 1000, students);
    }
    System.out.println("123:" + memcachedClient.get("students"));
    List<Student> students1 = memcachedClient.get("students");
    Iterator<Student> s = students1.iterator();
    while (s.hasNext()) {

        System.out.println("这些人是：" + s.next().toString());

    }
    model.addAttribute("students", students1);
    return "stuJson";
}

  修改的memcache.properties如下

# the pool size(the number of client)
memcached.connectionPoolSize=50  
# in this mode, when a node out, it will throws MemcachedException when call this node
memcached.failureMode=true  
#server1
memcached.server1.host=127.0.0.1  
memcached.server1.port=11211  
memcached.server1.weight=1  
#server2

测试的结果

测试json数据

无缓存json测试

缓存非json测试 测到一般请求卡死了

缓存json测试

缓存json同时修改memcaceh.properties的ip地址的测试

测试结果   有缓存的json同时修改memcaceh.properties的ip地址的测试  90%line为1536ms  吞吐量throughput：59.5/sec数据最好。      
明天计划的事情：负载均衡，  Rigs                         
遇到的问题：以解决                           
收获：缓存memcache的使用
