Springboot入门日志管理和缓存支持

一、日志管理

①添加log4j配置文件

#log4j.rootLogger=CONSOLE,info,error,DEBUGlog4j.rootLogger=info,error,CONSOLE,DEBUGlog4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender     log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout     log4j.appender.CONSOLE.layout.ConversionPattern=%d{yyyy-MM-dd-HH-mm} [%t] [%c] [%p] - %m%n     log4j.logger.info=infolog4j.appender.info=org.apache.log4j.DailyRollingFileAppenderlog4j.appender.info.layout=org.apache.log4j.PatternLayout     log4j.appender.info.layout.ConversionPattern=%d{yyyy-MM-dd-HH-mm} [%t] [%c] [%p] - %m%n  log4j.appender.info.datePattern='.'yyyy-MM-ddlog4j.appender.info.Threshold = info   log4j.appender.info.append=true   #log4j.appender.info.File=/home/admin/pms-api-services/logs/info/api_services_infolog4j.appender.info.File=/Users/dddd/Documents/testspace/pms-api-services/logs/info/api_services_infolog4j.logger.error=error  log4j.appender.error=org.apache.log4j.DailyRollingFileAppenderlog4j.appender.error.layout=org.apache.log4j.PatternLayout     log4j.appender.error.layout.ConversionPattern=%d{yyyy-MM-dd-HH-mm} [%t] [%c] [%p] - %m%n  log4j.appender.error.datePattern='.'yyyy-MM-ddlog4j.appender.error.Threshold = error   log4j.appender.error.append=true   #log4j.appender.error.File=/home/admin/pms-api-services/logs/error/api_services_errorlog4j.appender.error.File=/Users/dddd/Documents/testspace/pms-api-services/logs/error/api_services_errorlog4j.logger.DEBUG=DEBUGlog4j.appender.DEBUG=org.apache.log4j.DailyRollingFileAppenderlog4j.appender.DEBUG.layout=org.apache.log4j.PatternLayout     log4j.appender.DEBUG.layout.ConversionPattern=%d{yyyy-MM-dd-HH-mm} [%t] [%c] [%p] - %m%n  log4j.appender.DEBUG.datePattern='.'yyyy-MM-ddlog4j.appender.DEBUG.Threshold = DEBUG   log4j.appender.DEBUG.append=true   #log4j.appender.DEBUG.File=/home/admin/pms-api-services/logs/debug/api_services_debuglog4j.appender.DEBUG.File=/Users/dddd/Documents/testspace/pms-api-services/logs/debug/api_services_debug

②使用aop统一处理web请求日志

添加pom依赖

<dependency>            <groupId>org.springframework.boot</groupId>            <artifactId>spring-boot-starter-aop</artifactId></dependency>

写一个专门处理的工具类

@Aspect@Componentpublic class WebLogAspect {    private Logger logger = LoggerFactory.getLogger(getClass());    @Pointcut("execution(public * cn.iponkan.controller..*.*(..))")    public void webLog() {    }    @Before("webLog()")    public void doBefore(JoinPoint joinPoint) throws Throwable {        // 接收到请求，记录请求内容        ServletRequestAttributes attributes = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();        HttpServletRequest request = attributes.getRequest();        // 记录下请求内容        logger.info("URL : " + request.getRequestURL().toString());        logger.info("HTTP_METHOD : " + request.getMethod());        logger.info("IP : " + request.getRemoteAddr());        Enumeration<String> enu = request.getParameterNames();        //记录其他参数值        while (enu.hasMoreElements()) {            String name = (String) enu.nextElement();            logger.info("name:{},value:{}", name, request.getParameter(name));        }    }    @AfterReturning(returning = "ret", pointcut = "webLog()")    public void doAfterReturning(Object ret) throws Throwable {        // 处理完请求，返回内容        logger.info("RESPONSE : " + ret);    }}

二、缓存支持

①pom依赖

 <dependency>            <groupId>org.springframework.boot</groupId>            <artifactId>spring-boot-starter-cache</artifactId> </dependency>

②ehcahe配置文件

<?xml version="1.0" encoding="UTF-8"?><ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:noNamespaceSchemaLocation="http://ehcache.org/ehcache.xsd"updateCheck="false"><diskStore path="java.io.tmpdir/Tmp_EhCache" /><!-- 默认配置 --><defaultCache maxElementsInMemory="5000" eternal="false"timeToIdleSeconds="120" timeToLiveSeconds="120"memoryStoreEvictionPolicy="LRU" overflowToDisk="false" /><cache name="baseCache" maxElementsInMemory="10000"maxElementsOnDisk="100000" /></ehcache>

③Mapper层添加缓存依赖注解

@CacheConfig(cacheNames = "baseCache")public interface UserMapper{    @Cacheable    User getName(@Param("name")String name);}

④启动类中开启缓存

@EnableCaching//开启缓存

⑤清除缓存

@Controllerpublic class Indexcontroller {    @Autowired    private CacheManager cacheManager;    //清除缓存    @ResponseBody    @RequestMapping("/removeCache")    public  String removeCache(){        cacheManager.getCache("baseCache").clear();        return "success";    }}
