整合Druid数据源

pom依赖：

<!--引入druid数据源-->
<!-- https://mvnrepository.com/artifact/com.alibaba/druid -->
<dependency>
<groupId>com.alibaba</groupId>
<artifactId>druid</artifactId>
<version>1.1.10</version>
</dependency>

配置类：

@Configuration
public class DruidConfig {
      //prefix = "spring.datasource:" 配置文件属性名称
    @ConfigurationProperties(prefix = "spring.datasource")
    @Bean
    public DataSource druid(){
        return  new DruidDataSource();
    }

    //配置Druid监控
    //1，配置管理后台的servlet
    @Bean
    public ServletRegistrationBean statViewServlet(){
        //StatViewServlet 把我们的servlet和要截获的url传进去,url必须写"/druid/*"
        ServletRegistrationBean bean = new ServletRegistrationBean(new StatViewServlet(),"/druid/*");
        Map<String,String> initParams = new HashMap<>();
        //loginUsername，loginPassword不可写错，否则无法登陆
        initParams.put("loginUsername","admin");
        initParams.put("loginPassword","123456");
        initParams.put("allow","");//默认允许所有
        initParams.put("deny","192.168.0.114");
        bean.setInitParameters(initParams);
        return  bean;
    }

    //2,配置一个web监控的filter
    @Bean
    public FilterRegistrationBean  webStatFilter(){
        FilterRegistrationBean bean = new FilterRegistrationBean();
        bean.setFilter(new WebStatFilter());
        Map<String,String> initParams = new HashMap<>();
        initParams.put("exclusions","*.js,*.css,/druid/*");
        bean.setInitParameters(initParams);
        bean.setUrlPatterns(Arrays.asList("/*"));

        return  bean;
     }
}

数据源配置yml：

spring:
  datasource:
    username: root
    password: 123456
    url: jdbc:mysql://192.168.0.113/jdbc
    driver-class-name: com.mysql.jdbc.Driver
    type: com.alibaba.druid.pool.DruidDataSource
#    schema:
#       - classpath:department.sql
#   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
