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,DEBUG
log4j.rootLogger=info,error,CONSOLE,DEBUG
log4j.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=info
log4j.appender.info=org.apache.log4j.DailyRollingFileAppender
log4j.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-dd
log4j.appender.info.Threshold = info
log4j.appender.info.append=true
#log4j.appender.info.File=/home/admin/pms-api-services/logs/info/api_services_info
log4j.appender.info.File=/Users/dddd/Documents/testspace/pms-api-services/logs/info/api_services_info
log4j.logger.error=error
log4j.appender.error=org.apache.log4j.DailyRollingFileAppender
log4j.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-dd
log4j.appender.error.Threshold = error
log4j.appender.error.append=true
#log4j.appender.error.File=/home/admin/pms-api-services/logs/error/api_services_error
log4j.appender.error.File=/Users/dddd/Documents/testspace/pms-api-services/logs/error/api_services_error
log4j.logger.DEBUG=DEBUG
log4j.appender.DEBUG=org.apache.log4j.DailyRollingFileAppender
log4j.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-dd
log4j.appender.DEBUG.Threshold = DEBUG
log4j.appender.DEBUG.append=true
#log4j.appender.DEBUG.File=/home/admin/pms-api-services/logs/debug/api_services_debug
log4j.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
@Component
public 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
@Controller
public class Indexcontroller {
@Autowired
private CacheManager cacheManager;

//清除缓存
@ResponseBody
@RequestMapping("/removeCache")
public String removeCache(){
cacheManager.getCache("baseCache").clear();
return "success";
}

}
