整合Druid数据源

在pom.xml添加依赖

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

application.properties或者application.yml数据源类型设置为Druid数据源

spring:
  datasource:
#   数据源基本配置
    username: root
    password: ****
    driver-class-name: com.mysql.jdbc.Driver
    url: jdbc:mysql://****:3306/user
    type: com.alibaba.druid.pool.DruidDataSource #设置为Druid
#   数据源其他配置
    initialSize: 5
    minIdle: 5
    maxActive: 20
    maxWait: 60000
    timeBetweenEvictionRunsMillis: 60000
    minEvictableIdleTimeMillis: 300000
    validationQuery: SELECT 1 FROM DUAL
    testWhileIdle: true
    testOnBorrow: false
    testOnReturn: false
    poolPreparedStatements: 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  
    filters: stat,wall #,log4j
    maxPoolPreparedStatementPerConnectionSize: 20
    useGlobalDataSourceStat: true  
    connectionProperties: druid.stat.mergeSql=true;druid.stat.slowSqlMillis=500

导入Durid数据源

@Configuration
public class DruidConfig {
    @ConfigurationProperties(prefix = "spring.datasource")
    @Bean
    public DataSource druid() {
        return new DruidDataSource();
    }
    ///
    @Bean
    public ServletRegistrationBean statViewServlet() {
        ServletRegistrationBean bean = new ServletRegistrationBean(new StatViewServlet(), "/druid/*");
        Map<String,String> initParams = new HashMap<>();
        initParams.put("loginUsername","admin");
        initParams.put("loginPassword","123456");
        initParams.put("allow","");//允许登录账号  默认允许所有访问
        initParams.put("deny","192.168.1.1");//拒绝访问  
        bean.setInitParameters(initParams);
        return bean;
    }
    ///拦截 
    @Bean
    public FilterRegistrationBean webStatFilter(){
        FilterRegistrationBean bean = new FilterRegistrationBean();
        bean.setFilter(new WebStatFilter());

        Map<String,String> initParams = new HashMap<>();
        initParams.put("exclusions","*.js,*.css,/druid/*");///不拦截的请求  静态文件 和 druid的请求
        bean.setInitParameters(initParams);
        bean.setUrlPatterns(Arrays.asList("/*"));
        return bean;
    }
}

配置完成后重启程序
在浏览器中访问http://localhost:8080/druid/

@RestController
public class HelloController {
    @Autowired
    JdbcTemplate jdbcTemplate;
    @RequestMapping("/hello")
    public Map<String,Object> map(){
        List<Map<String,Object>> list = jdbcTemplate.queryForList("SELECT * FROM employee");
        return list.get(0);
    }
}

进行一次接口访问: http://localhost:8080/hello

sql监控

uri监控

记录就都有了
