swagger 和 druid 使用

1月2号辞职了,离职前看过swagger 和 使用alibaba的druid监控访问.今天大年初一没事干,把步骤记录一下

• 先说swagger把,挺简单的

• 1:使用maven引入 两个jar包

		<!-- swagger 接口文档+ui界面 -->
		<dependency>
			<groupId>io.springfox</groupId>
			<artifactId>springfox-swagger2</artifactId>
			<version>2.9.2</version>
		</dependency>
		<dependency>
			<groupId>io.springfox</groupId>
			<artifactId>springfox-swagger-ui</artifactId>
			<version>2.9.2</version>
		</dependency>

• 2:写一个配置类;使用的springboot,在启动类同级新建一个config包,新建一个 SwaggerConfig 类

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import springfox.documentation.builders.ApiInfoBuilder;
import springfox.documentation.builders.RequestHandlerSelectors;
import springfox.documentation.service.ApiInfo;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;

@Configuration
public class SwaggerConfig {
	public ApiInfo createAI() {
		ApiInfo info = new ApiInfoBuilder().title("短信发送和验证").build();
		return info;
	}
	
	@Bean
	public Docket createDocket() {
		return new Docket(DocumentationType.SWAGGER_2).apiInfo(createAI()).select()
				.apis(RequestHandlerSelectors.basePackage("com.xxx.controller")).build();
	}
}

• 3:使用;在启动类同级 新建一个controler包,新建一个Test类

@Api // swagger会扫描这个@Api注解的类
@RestController
public class AliController {

	@Autowired
	AliService aliService;
	
	@ApiOperation("发送验证码,需要参数:phone(手机号) + cipher(约定密码)")
	@GetMapping("/xxxx")
	public String send(String phone,String cipher) {
		// ...
	}

• 4: 在启动类增加 @EnableSwagger2

@SpringBootApplication
@EnableSwagger2
public class SmsApplication {

	public static void main(String[] args) {
		SpringApplication.run(SmsApplication.class, args);
	}
}

• 5: 启动项目,访问 http://localhost:8080/swagger-ui.html

druid 连接池 以及监控

• 1:引入依赖

		<dependency>
			<groupId>com.alibaba</groupId>
			<artifactId>druid</artifactId>
			<version>1.1.6</version>
		</dependency>

• 2:编写配置类, 新建一个 DruidConfig类

import javax.servlet.Filter;
import javax.servlet.Servlet;

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;

import com.alibaba.druid.support.http.StatViewServlet;
import com.alibaba.druid.support.http.WebStatFilter;

@Configuration
public class DruidConfig {
	/**
	 * /druid/index.html
	 */
	@Bean
	public FilterRegistrationBean<Filter> filterRegistrationBean() {
		FilterRegistrationBean<Filter> frb = new FilterRegistrationBean<>();
		// 设置过滤器
		frb.setFilter(new WebStatFilter());
		frb.addInitParameter("exclusions", "*.js,*.gif,*.jpg,*.png,*.css,*.ico,/druid/*");
		// 过滤路径
		frb.addUrlPatterns("/*");
		return frb;
	}

	@Bean
	public ServletRegistrationBean<Servlet> druidServlet() {
		ServletRegistrationBean<Servlet> srb = new ServletRegistrationBean<>();
		// 设置servlet
		srb.setServlet(new StatViewServlet());
		// 设置触发路径
		srb.addUrlMappings("/druid/*");
		return srb;
	}
}

• 3:启动项目,访问 http://localhost:8080/druid
  可以查看数据源,sql监控,url监控
