introduction:
Druid appeared (*)druid property for user to setup, which made me find it hard to find it. I checked the official documents and found no problems. Finally found the following solution. Hope it helps you. .
If you have already configured it, directly change druid-1.0.12.jar, directly change the version to: druid-1.0.11.jar or upgrade to the latest version druid-1.0.29.jar (validated on 2017-04-07) , Reboot, save some time and don't have to look down, here are the steps I found to solve the problem.
1. Introduce the jar package in the maven project pom.xml:
<dependency>
<groupId>com.alibaba</groupId>
<artifactId>druid</artifactId>
<version>1.0.12</version>
</dependency>
2. Configure the data source:
<!-- druid setting -->
<bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource"
init-method="init" destroy-method="close">
<property name="driverClassName" value="${ds.druid.driver}"/>
<property name="url" value="${ds.druid.url}"/>
<property name="username" value="${ds.druid.username}"/>
<property name="password" value="${ds.druid.password}"/>
<property name="initialSize" value="${ds.druid.initialSize}"/>
<property name="minIdle" value="${ds.druid.minIdle}"/>
<property name="maxActive" value="${ds.druid.maxActive}"/>
<property name="maxWait" value="${ds.druid.maxWait}"/>
<property name="timeBetweenEvictionRunsMillis" value="${ds.druid.timeBetweenEvictionRunsMillis}"/>
<property name="minEvictableIdleTimeMillis" value="${ds.druid.minEvictableIdleTimeMillis}"/>
<property name="filters" value="stat,wall" />
<!-- optional -->
<property name="proxyFilters">
<list>
<ref bean="stat-filter"/>
</list>
</property>
</bean>
<!-- The optional druid monitoring statistics bean corresponds to the proxyFilters in the dataSource above -->
<bean id="stat-filter" class="com.alibaba.druid.filter.stat.StatFilter">
<property name="slowSqlMillis" value="1000" />
<property name="logSlowSql" value="true" />
<property name="mergeSql" value="true" />
</bean>
3. Find the web.xml under the project and add the following configuration:
<!-- Database monitoring start -->
<servlet>
<servlet-name>DruidStatView</servlet-name>
<!-- The servlet that displays the monitoring page -->
<servlet-class>com.alibaba.druid.support.http.StatViewServlet</servlet-class>
<init-param>
<param-name>profileEnable</param-name>
<param-value>true</param-value>
</init-param>
<init-param>
<param-name>resetEnable</param-name>
<param-value>false</param-value>
</init-param>
<!-- Optional login username and password-->
<init-param>
<param-name>loginUsername</param-name>
<param-value>druid</param-value>
</init-param>
<init-param>
<param-name>loginPassword</param-name>
<param-value>druid</param-value>
</init-param>
</servlet>
<servlet-mapping>
<servlet-name>DruidStatView</servlet-name>
<url-pattern>/druid/*</url-pattern>
</servlet-mapping>
4. After starting the project, enter the following address in the browser, you can see the login interface
http://localhost:8888/druid/
Enter username and password: druid
5. Click "Data Source", and " (*)druid property for user to setup " will appear
6. Reduce the version of the jar package introduced by maven from 1.0.12 to 1.0.11
<dependency>
<groupId>com.alibaba</groupId>
<artifactId>druid</artifactId>
<version>1.0.11</version>
</dependency>
or use:
<dependency>
<groupId>com.alibaba</groupId>
<artifactId>druid</artifactId>
<version>1.0.29</version>
</dependency>
7, start again, as shown below, you're done~~~
