springboot2配置druid数据库连接池

注意配置以下的依赖：

        <!-- 引入druid数据源-->
        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>druid</artifactId>
            <version>1.1.8</version>
        </dependency>

        <!-- alibaba的druid数据库连接池 -->
        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>druid-spring-boot-starter</artifactId>
            <version>1.1.0</version>
        </dependency>

        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <!-- 注意修改mysql的版本-->
            <scope>8.0.12</scope>
        </dependency>

        <dependency>
            <groupId>log4j</groupId>
            <artifactId>log4j</artifactId>
            <version>1.2.17</version>
        </dependency>

代码如下：

@Configuration
public class DruidConfig {

    @ConfigurationProperties(prefix = "spring.datasource")
    @Bean
    public DataSource druid() {
        return new DruidDataSource();
    }

    // 配置Druid的监控
    // 1、配置一个管理后台的Servlet
    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","localhost"); //默认就是允许所有访问
        initParams.put("deny","192.168.1.103");
        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<>();
        // 配置不拦截的静态资源文件
        initParams.put("exclusion","*.js,*.css,/druid/*");
        bean.setInitParameters(initParams);
        // 拦截所有请求
        bean.setUrlPatterns(Arrays.asList("/*"));
        return bean;
    }
}
