一.添加依賴

<dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>druid</artifactId>
            <version>1.1.6</version>

</dependency>

使用下面這個 上面那個會使SQL監控沒數據。。 我也不知道why..　　　　　　

<dependency>
    <groupId>com.alibaba</groupId>
    <artifactId>druid-spring-boot-starter</artifactId>
    <version>1.1.6</version>
</dependency>

二.修改application.properties中Druid的配置

druid:
filters: stat
max-active: 20
initial-size: 1
max-wait: 30000
min-idle: 1
time-between-eviction-runs-millis: 60000
min-evictable-idle-time-millis: 300000
test-while-idle: true
test-on-borrow: false
test-on-return: false
pool-prepared-statements: false
max-open-prepared-statements: -1
 

remove-abandoned: true
remove-abandoned-timeout: 180
web-stat-filter-exclusions: ‘*.js,*.gif,*.jpg,*.bmp,*.png,*.css,*.ico,/druid/*,/download/*,/wj/*,/assets/*‘

三.編寫文件

DruidStatViewServlet.java

@SuppressWarnings("serial")
@WebServlet(urlPatterns = "/druid/*",
        initParams={
                //@WebInitParam(name="allow",value="10.238.100.189,127.0.0.1"),
 
// IP白名單 (沒有配置或者為空，則允許所有訪問)
                @WebInitParam(name="allow",value="127.0.0.1"),// IP白名單 (沒有配置或者為空，則允許所有訪問)
                @WebInitParam(name="deny",value="192.168.16.111"),// IP黑名單 (存在共同時，deny優先於allow)
                @WebInitParam(name="loginUsername",value="druid"),// 用戶名
                @WebInitParam(name="loginPassword",value="druid"),// 密碼
                @WebInitParam(name="resetEnable",value="false")// 禁用HTML頁面上的“Reset All”功能
        })
public class DruidStatViewServlet extends StatViewServlet {

}

DruidStatFilter

@WebFilter(filterName="druidWebStatFilter",urlPatterns="/*",
        initParams={
                @WebInitParam(name="exclusions",value="*.js,*.gif,*.jpg,*.bmp,*.png,*.css,*.ico,/druid/*")// 忽略資源
        })
public class DruidStatFilter extends WebStatFilter {

}

四.在程序入口增加註解 @ServletComponentScan 用來掃描Servlet類
