spring boot之配置druid

不了解druid，请参考这里。

新增文件：

import com.alibaba.druid.pool.DruidDataSource;
import com.alibaba.druid.support.http.StatViewServlet;
import com.alibaba.druid.support.http.WebStatFilter;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.context.embedded.FilterRegistrationBean;
import org.springframework.boot.context.embedded.ServletRegistrationBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import javax.sql.DataSource;
import java.sql.SQLException;

@Configuration
public class DruidConfiguration {
    @Bean
    public ServletRegistrationBean druidServlet() {
        return new ServletRegistrationBean(new StatViewServlet(), "/druid/*");
    }

    @Bean
    public DataSource druidDataSource(@Value("${spring.datasource.driverClassName}") String driver,
                                      @Value("${spring.datasource.url}") String url,
                                      @Value("${spring.datasource.username}") String username,
                                      @Value("${spring.datasource.password}") String password) {
        DruidDataSource druidDataSource = new DruidDataSource();
        druidDataSource.setDriverClassName(driver);
        druidDataSource.setUrl(url);
        druidDataSource.setUsername(username);
        druidDataSource.setPassword(password);
        try {
            druidDataSource.setFilters("stat, wall");
        } catch (SQLException e) {
            e.printStackTrace();
        }
        return druidDataSource;
    }

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

用到的Maven依赖：

<druid.version>1.0.11</druid.version>

<dependency>
    <groupId>com.alibaba</groupId>
    <artifactId>druid</artifactId>
    <version>${druid.version}</version>
</dependency>
