druid坐标

spring:
  datasource:
    username: root

    url: jdbc:mysql://localhost:3306/shiro?useUnicode=true&characterEncoding=utf-8&serverTimezone=UTC
    driver-class-name: com.mysql.cj.jdbc.Driver
    type: com.alibaba.druid.pool.DruidDataSource


    #Spring Boot 默认是不注入这些属性值的，需要自己绑定
    #druid 数据源专有配置
    initialSize: 5
    minIdle: 5
    maxActive: 20
    maxWait: 60000

    #配置监控统计拦截的filters，stat:监控统计、log4j：日志记录、wall：防御sql注入
    #如果允许时报错  java.lang.ClassNotFoundException: org.apache.log4j.Priority
    #则导入 log4j 依赖即可，Maven 地址：https://mvnrepository.com/artifact/log4j/log4j

druid 配置:

 1 @Configuration
 2 public class DruidConfig {
 3 
 4     @ConfigurationProperties(prefix = "spring.datasource")
 5     @Bean
 6     public DataSource druidDataSource() {
 7         return new DruidDataSource();
 8     }
 9 
10     //后台监控
11     @Bean
12     public ServletRegistrationBean statViewServlet() {
13 
14         ServletRegistrationBean<StatViewServlet> bean = new ServletRegistrationBean<>(new StatViewServlet(),"/druid/*");
15 
16         //后台需要有人登录的登录密码
17         HashMap<String, String> initParameters = new HashMap<>();
18 
19         //增加配置
20         initParameters.put("loginUsername", "admin");   //登录的key    是固定的  loginUsername  loginPassword
21         initParameters.put("loginPassword", "123456");
22 
23         //允许谁可以访问
24         initParameters.put("allow", "");
25 
26         //禁止谁可以访问
27 //        initParameters.put("kuangsheng", "192.168.11.123");
