一、项目介绍(本项目用的编程语言是jdk8,项目源码:https://github.com/zhzhair/spring-boot-druid.git)
  1.引入pom依赖:
  <dependencies>
    <dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-data-redis</artifactId>
    </dependency>
    <dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
    <dependency>
      <groupId>org.mybatis.spring.boot</groupId>
      <artifactId>mybatis-spring-boot-starter</artifactId>
    <version>1.3.2</version>
    </dependency>
    <dependency>
      <groupId>mysql</groupId>
      <artifactId>mysql-connector-java</artifactId>
      <scope>runtime</scope>
    </dependency>
    <dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-test</artifactId>
      <scope>test</scope>
    </dependency>

    <dependency>
      <groupId>com.alibaba</groupId>
      <artifactId>druid-spring-boot-starter</artifactId>
      <version>1.1.14</version>
    </dependency>
  </dependencies>
  由引入的jar包可知,项目用MySQL + mybatis + redis架构,数据库连接池用阿里的druid

  2.配置文件application.yml配置(配置MySQL数据源、druid连接池及监控、redis):
  spring:
    datasource:
    driver-class-name: com.mysql.jdbc.Driver
    url: "jdbc:mysql://127.0.0.1:3306/demo?useUnicode=true&characterEncoding=UTF-8&useSSL=false"
    username: root
    password: 123456
    type: com.alibaba.druid.pool.DruidDataSource
    druid:
      max-active: 100
      min-idle: 10
      max-wait: 60000
      filter:
        stat:
          merge-sql: true
          slow-sql-millis: 200
      test-on-borrow: true
      validation-query: SELECT 1
      use-global-data-source-stat: true
      # 配置监控统计拦截的filters,去掉后监控界面sql无法统计,'wall'用于防火墙
      # http://127.0.0.1:8080/druid2/index.html
      filters: stat,wall,slf4j
      pool-prepared-statements: true
      max-pool-prepared-statement-per-connection-size: 20
    redis:
      host: 127.0.0.1
      password:
      database: 0
      timeout: PT1M1S
      jedis:
        pool.max-active: 200
        pool.max-idle: 50
        pool.max-wait: PT-1S
        pool.min-idle: 10

  table-num: 64

  3.引入druid配置类(sql和uri监控访问地址:http://localhost:8080/druid/index.html,用户名和密码分别是admin和123456):

    package com.example.demo.config.druid;

    import com.alibaba.druid.support.http.StatViewServlet;
    import com.alibaba.druid.support.http.WebStatFilter;
    import org.springframework.boot.web.servlet.FilterRegistrationBean;
    import org.springframework.boot.web.servlet.ServletRegistrationBean;
    import org.springframework.context.annotation.Bean;
    import org.springframework.context.annotation.Configuration;

    @Configuration
    public class DruidConfiguration {
        @Bean
        public ServletRegistrationBean DruidStatViewServle2() {
            //org.springframework.boot.context.embedded.ServletRegistrationBean提供类的进行注册.
            ServletRegistrationBean<StatViewServlet> servletRegistrationBean = new ServletRegistrationBean<>(new StatViewServlet(), "/druid2#zs#");
            //添加初始化参数:initParams
            servletRegistrationBean.addUrlMappings("/druid#zs#");
            //白名单:
    //        servletRegistrationBean.addInitParameter("allow","192.168.1.106");
            //IP黑名单 (存在共同时,deny优先于allow) : 如果满足deny的话提示:Sorry, you are not permitted to view this page.
            // servletRegistrationBean.addInitParameter("deny", "192.168.1.73");
            //登录查看信息的账号密码.
            servletRegistrationBean.addInitParameter("loginUsername","admin");
            servletRegistrationBean.addInitParameter("loginPassword","123456");
            //是否能够重置数据.
            servletRegistrationBean.addInitParameter("resetEnable","false");
            return servletRegistrationBean;
        }
        
        @Bean
        public FilterRegistrationBean druidStatFilter2(){
            FilterRegistrationBean<WebStatFilter> filterRegistrationBean = new FilterRegistrationBean<>(new WebStatFilter());
            filterRegistrationBean.setName("druidFilter2");
            //添加过滤规则.
            filterRegistrationBean.addUrlPatterns("#zs#");
            //添加不需要忽略的格式信息.
            filterRegistrationBean.addInitParameter("exclusions","*.js,*.gif,*.jpg,*.png,*.css,*.ico,/druid2#zs#");
            return filterRegistrationBean;
        }

    }

 

  4.在测试类创建表user_*和user_mobile_*:

    @RunWith(SpringRunner.class)
    @SpringBootTest
    public class DemoApplicationTests {

        @Resource
        private TestUserService userService;
        @Test
        public void contextLoads() {
            userService.dropTables();
            userService.createTables();
        }

    }
    
    @Service
    public class TestUserServiceImpl implements TestUserService {
        @Resource
        private UserMapper userMapper;//jdbc操作接口
        @Value("${table-num}")
        private int tableNum;//分表的个数

        @Override
        public void dropTables() {
            IntStream.range(0,tableNum).parallel().forEach(this::dropTables);
        }

        private void dropTables(int i){
            userMapper.dropTable("user_" + i);
            userMapper.dropTable("user_mobile_" + i);
        }

        @Override
        public void createTables() {
            IntStream.range(0,tableNum).parallel().forEach(this::createTables);
        }

        private void createTables(int i){
            String suffix = String.valueOf(i);
            userMapper.createTableUser(suffix);
            userMapper.createTableUserMobile(suffix);
        }
    }

 

  5.编写restful风格的接口(包括登录和注册):

    @RestController
    @RequestMapping("test/user")
    public class TestUserController extends BaseController {
        @Resource
        private TestUserService userService;
        @Resource
        private TokenManager tokenManager;//给登录用户生成token,并放到redis
        @RequestMapping(value = "/loginByMobile", method = {RequestMethod.GET}, produces = {MediaType.APPLICATION_JSON_VALUE})
        public BaseResponse<LoginResponse> loginByMobile() {
            BaseResponse<LoginResponse> baseResponse = new BaseResponse<>();
            Integer userId = userService.getUserIdByMobile();
            if(userId != null){
                baseResponse.setCode(0);
                baseResponse.setMsg("手机号登录成功");
                String token = tokenManager.generateToken(userId);
                LoginResponse loginResponse = new LoginResponse();
                loginResponse.setUserId(userId);
                loginResponse.setToken(token);
                loginResponse.setExpire(System.currentTimeMillis() + 3600 * 1000);
                baseResponse.setData(loginResponse);
            }else{
                baseResponse.setCode(-3);
                baseResponse.setMsg("手机号未注册");
            }
            return baseResponse;
        }

        @RequestMapping(value = "/register", method = {RequestMethod.POST}, produces = {MediaType.APPLICATION_JSON_VALUE})
        public BaseResponse<User> register() {
            BaseResponse<User> baseResponse = new BaseResponse<>();
            Integer userId = userService.getUserIdByMobile();
            if(userId == null){
                User user = userService.register();
                baseResponse.setCode(0);
                baseResponse.setData(user);
                baseResponse.setMsg("注册成功");
            }else{
                baseResponse.setCode(1);
                baseResponse.setMsg("手机号已被注册");
            }
            return baseResponse;
        }
    }
    
    @Service
    public class TestUserServiceImpl implements TestUserService {
        @Resource
        private UserService userService;
        @Value("${table-num}")
        private int tableNum;//分表的个数

        @Override
        public Integer getUserIdByMobile() {
            return userService.getUserIdByMobile(getMobileStr());
        }

        @Override
        public User register() {
            UserRequest userRequest = new UserRequest();
            userRequest.setMobile(getMobileStr());
            userRequest.setIcon("http://127.0.0.1/"+getMobileStr()+".jpg");
            int rand = new Random().nextInt(4);
            userRequest.setNickname(new String[]{"xiaoming","xiaohong","xiaoqiang","xiaoli"}[rand]);
            return userService.register(userRequest);
        }

        #zs#*
         * 模拟手机号
         #fzs#
        private String getMobileStr(){
            String[] strings = {"13","15","16","18"};
            String beginString = strings[new Random().nextInt(4)];
            int a = new Random().nextInt(10_0000_0000);
            String endString = String.valueOf(a);
            int length = 9 - endString.length();
            StringBuilder stringBuilder = new StringBuilder(beginString);
            for (int i = 0; i < length; i++) {
                stringBuilder.append("0");
            }
            return stringBuilder.append(endString).toString();
        }
    }    
    
    @Service
    public class UserServiceImpl implements UserService {
        private final String USER_ID_INC = "USER_ID_INC";
        @Resource
        private UserMapper userMapper;//jdbc操作接口
        @Resource(name = "stringRedisTemplate")
        private RedisTemplate<String, String> redisTemplate;

        @Value("${table-num}")
        private int tableNum;//分表的个数

        @Transactional(isolation = Isolation.REPEATABLE_READ)
        @Override
        public User register(UserRequest userRequest) {
            String usercode = redisTemplate.opsForValue().get(USER_ID_INC);
            Integer userId;
            if(usercode == null){//如果redis的数据丢失,就找出最大的userId,并给USER_ID_INC赋值
                int temp = 0;
                for (int i = 0; i < tableNum; i++) {
                    Integer maxUserId = userMapper.getMaxUserId(String.valueOf(i));
                    if(maxUserId != null && temp < maxUserId){
                        temp = maxUserId;
                    }
                }
                userId = temp + 1;
                redisTemplate.opsForValue().set(USER_ID_INC,String.valueOf(userId));
            }else{
                Long num = redisTemplate.opsForValue().increment(USER_ID_INC,1);
                userId = Integer.valueOf(num + "");
            }
            User user = new User();
            user.setUserId(userId);
            user.setMobile(userRequest.getMobile());
            user.setIcon(userRequest.getIcon());
            user.setNickname(userRequest.getNickname());
            int rem = userId % tableNum;
            userMapper.insertUser(user,String.valueOf(rem));
            int rem0 = Math.abs(userRequest.getMobile().hashCode()) % tableNum;
            String mobile = userRequest.getMobile();
            userMapper.insertUserMobile(mobile,userId,String.valueOf(rem0));
            return user;
        }

        @Override
        public Integer getUserIdByMobile(String mobile) {
            int rem = Math.abs(mobile.hashCode()) % tableNum;
            return userMapper.getUserByMobile(mobile,String.valueOf(rem));
        }

    }

 

二、用jmeter做并发测试(jmeter版本4.0):
  1.双击打开bin目录下的jmeter.bat文件,菜单选简体中文:Options->Choose language->Chinese(Simplified)。点文件夹图标可以选择已有的jmeter脚本。

  2.右键测试计划->添加->Threads(Users)->线程组,然后配置执行线程数、持续时间等信息。登录和注册我都建了单独的线程组,其中:登录的线程数36000,持续时间600秒;注册的线程数6000,持续时间600秒。
  3.右键测试计划->添加->监听器->(查看结果数和聚合报告等,用于分析并发测试结果)。
  4.分别右键选中登录和注册的线程组->添加->sampler->HTTP请求,配置如下:
登录和注册的协议都填http,IP都填127.0.0.1,端口号都填8080。登录的方式选GET,注册的方式选POST。登录的路径填/test/user/loginByMobile,注册的路径填/test/user/register。
  5.点击打开聚合报告,启动项目,点击菜单栏绿色的三角形图标运行,观察聚合报告的结果如下图所示:

 

三、查看druid的sql监控和uri监控:
  jmeter运行时,访问http://localhost:8080/druid/index.html,sql监控和webUI等监控结果如图所示:
