一,连接池的配置
在pom.xml中添加,druid的maven信息
<dependency> <groupId>com.alibaba</groupId> <artifactId>druid</artifactId> <version>1.1.21</version> </dependency>
数据源设置:
要在init-method设置init方法,才能在监控页面中查看数据源等操作
<!--使用druid数据源--> <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource" init-method="init"> <!--注入连接属性--> <property name="driverClassName" value="${jdbc.driverClass}"/> <property name="url" value="${jdbc.url}"/> <property name="username" value="${jdbc.user}"/> <property name="password" value="${jdbc.password}"/> <!--初始化连接池大小--> <property name="initialSize" value="5"></property> <!--设置最大连接数--> <property name="maxActive" value="10"></property> <!--设置等待时间--> <property name="maxWait" value="5000"/> <!--配置数据源监控的filter--> <property name="filters" value="stat"></property> </bean>
二,数据源监控的配置:
druid数据源监控是通过其support
包下的StatViewServlet
来提供的,所以要在web.xml
进行servlet的配置
StatViewServlet的部分代码如下:
public class StatViewServlet extends ResourceServlet { private static final Log LOG = LogFactory.getLog(StatViewServlet.class); private static final long serialVersionUID = 1L; public static final String PARAM_NAME_RESET_ENABLE = "resetEnable"; public static final String PARAM_NAME_JMX_URL = "jmxUrl"; public static final String PARAM_NAME_JMX_USERNAME = "jmxUsername"; public static final String PARAM_NAME_JMX_PASSWORD = "jmxPassword"; private DruidStatService statService = DruidStatService.getInstance(); private String jmxUrl = null; private String jmxUsername = null; private String jmxPassword = null; private MBeanServerConnection conn = null; public StatViewServlet() { super("support/http/resources"); }
StatViewServlet
其资源路径在
"support/http/resources" 主要是一些静态的前端资源文件,所以要在filter中过滤
web.xml配置
<!-- druid的监控配置 --> <servlet> <servlet-name>StatViewServlet</servlet-name> <servlet-class>com.alibaba.druid.support.http.StatViewServlet</servlet-class> <!--登陆名--> <init-param> <param-name>loginUsername</param-name> <param-value>admin</param-value> </init-param> <!-- 登录密码--> <init-param> <param-name>loginPassword</param-name> <param-value>root</param-value> </init-param> <!--白名单--> <init-param> <param-name>allow</param-name> <param-value></param-value> </init-param> <!--黑名单--> <init-param> <param-name>deny</param-name> <param-value></param-value> </init-param> </servlet> <servlet-mapping> <servlet-name>StatViewServlet</servlet-name> <url-pattern>/druid/*</url-pattern> </servlet-mapping> <filter> <filter-name>WebStatFilter</filter-name> <filter-class>com.alibaba.druid.support.http.WebStatFilter</filter-class> <!--过滤的样式--> <init-param> <param-name>exclusions</param-name> <param-value>*.js,*.gif,*.css,*.ico,*.jpg,*.png,/druid/*</param-value> </init-param> </filter> <filter-mapping> <filter-name>WebStatFilter</filter-name> <servlet-name>StatViewServlet</servlet-name> </filter-mapping> <!--druid监控配置结束-->
配置完成访问项目路径下的 “/druid/就能进入监控页面,登入用户名和密码就是在servlet中配置的
