## springboot配置druid监控 ##

启动类上加上 @ServletComponentScan注解  
如果 配置的多数据源 不用默认的 配置 @SpringBootApplication(exclude=DataSourceAutoConfiguration.class)加上这个注解

### application.properties 配置文件 ###

### 多数据源 配置 ###

在源配置类中 配置

        }

            wfilter.setConfig(wallConfig);
            return wfilter;
        }
