谷粒商城心得二

由于有很多模块，都需要和数据库进行交互，这样配置p6spy比较麻烦。

查看官网的配置信息

https://p6spy.readthedocs.io/en/latest/configandusage.html#properties-exposal-via-jmx

 于是可以提取到common模块。添加2个配置类

@Configuration
public class P6SpyConfig {

    /**
     * P6数据源包装, 打印SQL语句
     */
    @Bean
    public P6DataSourceBeanPostProcessor p6DataSourceBeanPostProcessor() {
        return new P6DataSourceBeanPostProcessor();
    }

    class P6DataSourceBeanPostProcessor implements BeanPostProcessor, PriorityOrdered {
        @Override
        public Object postProcessBeforeInitialization(Object bean, String beanName) throws BeansException {
            return bean;
        }

        @Override
        public Object postProcessAfterInitialization(Object bean, String beanName) throws BeansException {
            if (bean instanceof DataSource) {
                P6SpyPropertyConfig.init();
                return new P6DataSource((DataSource) bean);
            }
            return bean;
        }

        @Override
        public int getOrder() {
            return Ordered.LOWEST_PRECEDENCE;
        }
    }

}

public class P6SpyPropertyConfig {

    private static final String PRE = "p6spy.config.";

    /**
     * 初始化设置
     */
    public static void init(){
        Properties prop = System.getProperties();
        prop.put(PRE + "autoflush"                      , "false");
        prop.put(PRE + "dateformat"                     , "yyyy-MM-dd HH:mm:ss");
        prop.put(PRE + "appender"                       , "com.p6spy.engine.spy.appender.Slf4JLogger");
        prop.put(PRE + "logMessageFormat"               , "com.p6spy.engine.spy.appender.CustomLineFormat");
        prop.put(PRE + "customLogMessageFormat"         , "%(executionTime)ms | %(sqlSingleLine)");
        prop.put(PRE + "databaseDialectDateFormat"      , "yyyy-MM-dd");
        prop.put(PRE + "databaseDialectTimestampFormat" , "yyyy-MM-dd HH:mm:ss");
        prop.put(PRE + "databaseDialectBooleanFormat"   , "boolean");
        prop.put(PRE + "filter"                         , "true");
        prop.put(PRE + "exclude"                        , "^SELECT 1");
        prop.put(PRE + "excludecategories"              , "info,debug,result,resultset,batch,commit,rollback");
    }
}　　

但是发现的码云生效，需要在各个启动类上，把这个路径扫描进去。

 就会生效了。
