配置类(配置信息在yml文件中)

配置类

@Configuration
public class DataSourceConfig {
    /**
     * *注册一个StatViewServlet
     * *@return
     */
    @Bean
    @ConfigurationProperties("datasource.druid.stat-view-servlet")
    public ServletRegistrationBean druidStatViewServle(){
        return new ServletRegistrationBean(new StatViewServlet());
    }

    @Bean
    @ConfigurationProperties("datasource.druid.web-stat-filter")
    public FilterRegistrationBean druidStatFilter() {
        return new FilterRegistrationBean(new WebStatFilter());
    }

}

yml文件

dataSource:
druid:
       stat-view-servlet:
           #是否启用StatViewServlet（监控页面）默认值为false（考虑到安全问题默认并未启动，如需启用建议设置密码或白名单以保障安全）
           enabled: true
           url-mappings: "/druid2/*"
           # 该参数为map, key必须保持该格式
           init-parameters:
               loginUsername: "admin"
               loginPassword: "admin"
               resetEnable: "false"
       # WebStatFilter配置，说明请参考Druid Wiki，配置_配置WebStatFilter
       web-stat-filter:
           #是否启用StatFilter默认值false
           enabled: true
           url-patterns: "/*"
           # 该参数为map, key必须保持该格式
           init-parameters:
               exclusions: "*.js,*.gif,*.jpg,*.png,*.css,*.ico,/druid/*"

注意事项

1. init-parameters在对应实体类中是map,spring读取yml后会直接进行put,所以loginUsername,loginPassword等不可以写成login-username,login-password格式
2. 在设置resetEnable(是否可以重置)后, 页面上方的重置按钮还是可以点击,并返回已重置.但是实际上没有进行操作
