1.引入包configurations {providedRuntime   // remove default logger   all*.exclude group: 'org.springframework.boot', module: 'spring-boot-starter-logging'}dependencies { compile('org.springframework.boot:spring-boot-starter-data-jpa') compile('org.springframework.boot:spring-boot-starter-data-redis') compile('org.springframework.boot:spring-boot-starter-data-rest') compile('org.springframework.boot:spring-boot-starter-freemarker') compile('org.springframework.boot:spring-boot-starter-web') compile('org.springframework.boot:spring-boot-starter-web-services') compile('org.mybatis.spring.boot:mybatis-spring-boot-starter:1.3.2') compile('org.springframework.boot:spring-boot-starter-log4j2:2.0.3.RELEASE') compile('org.mybatis.spring.boot:mybatis-spring-boot-starter:1.3.2') compileOnly('org.projectlombok:lombok') runtime('mysql:mysql-connector-java') compile ('com.alibaba:fastjson:1.2.47') testCompile('org.springframework.boot:spring-boot-starter-test')}

2.在路径rescourse下配置log4j2.properties

name = PropertiesConfig#property.filename = target/logsproperty.filename = D:\\log

#appenders = console, file#配置值是appender的类型，并不是具体appender实例的nameappenders = rolling

appender.rolling.type = RollingFileappender.rolling.name = RollingLogFileappender.rolling.fileName=${filename}/automationlogs.logappender.rolling.filePattern = ${filename}/automationlogs-%d{MM-dd-yy-HH-mm-ss}-%i.logappender.rolling.layout.type = PatternLayoutappender.rolling.layout.pattern=[%-5level] %d{yyyy-MM-dd HH:mm:ss.SSS} [%t] %c{1} - %msg%nappender.rolling.policies.type = Policiesappender.rolling.policies.size.type = SizeBasedTriggeringPolicyappender.rolling.policies.size.size=100MBappender.rolling.strategy.type = DefaultRolloverStrategyappender.rolling.strategy.max = 5

rootLogger.level = tracerootLogger.appenderRef.rolling.ref = RollingLogFile

#rootLogger.appenderRef.rolling.ref = rolling

3.java ，其中@Slf4j注解相当于声明变量，可以直接使用log.info()

@WebFilter(filterName = "RequestLog", urlPatterns = "/*")@SpringBootApplication//重点@ServletComponentScanpublic class DemoApplication {启动类}这两个注解相当于配置过滤器

上述是日志的配置情况，下面介绍aop切入日志的的方法@Target({ ElementType.PARAMETER, ElementType.METHOD })@Retention(RetentionPolicy.RUNTIME)@Documentedpublic @interface SystemControllerLog {
