spring boot2.0.4集成druid,用jmeter并发测试工具调用接口,druid查看监控的结果
一、项目介绍(本项目用的编程语言是jdk8,项目源码: https://github.com/zhzhair/mybatis-druid-spring-boot.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/*"); //添加初始化参数:initParams servletRegistrationBean.addUrlMappings("/druid/*"); //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("/*"); //添加不需要忽略的格式信息. filterRegistrationBean.addInitParameter("exclusions","*.js,*.gif,*.jpg,*.png,*.css,*.ico,/druid2/*"); 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); } /** * 模拟手机号 */ 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:
