SpringBoot1.5.10.RELEASE整合druid

1、先在pom文件中导入druid的jar包

         <dependency>
             <groupId>com.alibaba</groupId>
             <artifactId>druid</artifactId>
             <version>1.1.10</version>
         </dependency>    

2、新建DruidDataSourceConfig 配置类

 package com.wantom.config;

 import com.alibaba.druid.pool.DruidDataSource;
 import com.alibaba.druid.support.http.StatViewServlet;
 import com.alibaba.druid.support.http.WebStatFilter;
 import org.slf4j.Logger;
 import org.slf4j.LoggerFactory;
 import org.springframework.beans.factory.annotation.Value;
 import org.springframework.boot.context.properties.ConfigurationProperties;
 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 javax.sql.DataSource;
 import java.sql.SQLException;

 /**
 * @Name：DruidDataSourceConfig
 * @Description：数据源属性配置
 * @Version：V1.0.0
 * @Author：mYunYu
 * @Create Date：2018/11/6 11:30
 */
 @Configuration
 public class DruidDataSourceConfig {

     private Logger logger = LoggerFactory.getLogger(DruidDataSourceConfig.class);

     @Value("${spring.datasource.url}")
     private String dbUrl;

     @Value("${spring.datasource.username}")
     private String username;

     @Value("${spring.datasource.password}")
     private String password;

     @Value("${spring.datasource.driver-class-name}")
     private String driverClassName;

     @Value("${spring.datasource.initialSize}")
     private int initialSize;

     @Value("${spring.datasource.minIdle}")
     private int minIdle;

     @Value("${spring.datasource.maxActive}")
     private int maxActive;

     @Value("${spring.datasource.maxWait}")
     private int maxWait;

     @Value("${spring.datasource.timeBetweenEvictionRunsMillis}")
     private int timeBetweenEvictionRunsMillis;

     @Value("${spring.datasource.minEvictableIdleTimeMillis}")
     private int minEvictableIdleTimeMillis;

     @Value("${spring.datasource.validationQuery}")
     private String validationQuery;

     @Value("${spring.datasource.testWhileIdle}")
     private boolean testWhileIdle;

     @Value("${spring.datasource.testOnBorrow}")
     private boolean testOnBorrow;

     @Value("${spring.datasource.testOnReturn}")
     private boolean testOnReturn;

     @Value("${spring.datasource.filters}")
     private String filters;

     @Value("${spring.datasource.logSlowSql}")
     private String logSlowSql;

     @Bean
     public ServletRegistrationBean druidServlet() {
         ServletRegistrationBean reg = new ServletRegistrationBean();
         reg.setServlet(new StatViewServlet());
         reg.addUrlMappings("/druid/*");
         reg.addInitParameter("loginUsername", username);
         reg.addInitParameter("loginPassword", password);
         reg.addInitParameter("logSlowSql", logSlowSql);
         return reg;
     }

     @Bean
     public FilterRegistrationBean filterRegistrationBean() {
         FilterRegistrationBean filterRegistrationBean = new FilterRegistrationBean();
         filterRegistrationBean.setFilter(new WebStatFilter());
         filterRegistrationBean.addUrlPatterns("/*");
         filterRegistrationBean.addInitParameter("exclusions", "*.js,*.gif,*.jpg,*.png,*.css,*.ico,/druid/*");
         filterRegistrationBean.addInitParameter("profileEnable", "true");
         return filterRegistrationBean;
     }

     public DataSource druidDataSource() {
         DruidDataSource datasource = new DruidDataSource();
         datasource.setUrl(dbUrl);
         datasource.setUsername(username);
         datasource.setPassword(password);
         datasource.setDriverClassName(driverClassName);
         datasource.setInitialSize(initialSize);
         datasource.setMinIdle(minIdle);
         datasource.setMaxActive(maxActive);
         datasource.setMaxWait(maxWait);
         datasource.setTimeBetweenEvictionRunsMillis(timeBetweenEvictionRunsMillis);
         datasource.setMinEvictableIdleTimeMillis(minEvictableIdleTimeMillis);
         datasource.setValidationQuery(validationQuery);
         datasource.setTestWhileIdle(testWhileIdle);
         datasource.setTestOnBorrow(testOnBorrow);
         datasource.setTestOnReturn(testOnReturn);
         try {
             datasource.setFilters(filters);
         } catch (SQLException e) {
             logger.error("druid configuration initialization filter", e);
         }
         return datasource;
     }

 }

3、再在application.properties配置文件中配置相关参数

 #配置druid数据源
 spring.datasource.driver-class-name=com.mysql.jdbc.Driver
 spring.datasource.url= jdbc:mysql://localhost:3306/dbName?useUnicode=true&characterEncoding=utf8&zeroDateTimeBehavior=round&transformedBitIsBoolean=true&autoReconnect=true&failOverReadOnly=false&allowMultiQueries=true
 spring.datasource.username=root
 spring.datasource.password=123456

 spring.datasource.type=com.alibaba.druid.pool.DruidDataSource
 # 下面为连接池的补充设置，应用到上面数据源中
 spring.datasource.initialSize=5
 spring.datasource.minIdle=5
 spring.datasource.maxActive=20
 # 配置获取连接等待超时的时间
 spring.datasource.maxWait=60000
 # 配置间隔多久才进行一次检测，检测需要关闭的空闲连接，单位是毫秒
 spring.datasource.timeBetweenEvictionRunsMillis=60000
 # 配置一个连接在池中最小生存的时间，单位是毫秒
 spring.datasource.minEvictableIdleTimeMillis=300000
 spring.datasource.validationQuery=SELECT 1 FROM DUAL
 spring.datasource.testWhileIdle=true
 spring.datasource.testOnBorrow=false
 spring.datasource.testOnReturn=false
 # 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
 spring.datasource.filters=stat,wall,log4j
 spring.datasource.logSlowSql=true

访问：http://localhost:8080/springboot/druid进行登录访问。

可以看出，是使用了druid连接池的
