阿新 • • 發佈：2018-10-31
1.新增pom.xml的依賴
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>top.ytheng</groupId> <artifactId>springboot-demo</artifactId> <version>0.0.1</version> <packaging>jar</packaging> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.0.5.RELEASE</version> <relativePath/> <!-- lookup parent from repository --> </parent> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding> <java.version>1.8</java.version> </properties> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-thymeleaf</artifactId> </dependency> <!-- 熱部署 --> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-devtools</artifactId> <optional>true</optional> <scope>true</scope> </dependency> <dependency> <groupId>org.mybatis.spring.boot</groupId> <artifactId>mybatis-spring-boot-starter</artifactId> <version>1.3.2</version> <scope>runtime</scope> </dependency> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <scope>runtime</scope> </dependency> <dependency> <groupId>com.alibaba</groupId> <artifactId>druid</artifactId> <version>1.1.6</version> </dependency> </dependencies> <build> <!-- 打包的名稱 --> <finalName>myspringboot</finalName> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> <plugin> <artifactId>maven-compiler-plugin</artifactId> <configuration> <source>1.8</source> <target>1.8</target> </configuration> </plugin> </plugins> </build> </project>
2.新增lockback-spring.xml配置檔案
<?xml version="1.0" encoding="UTF-8"?> <configuration> <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender"> <encoder> <pattern> %d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n </pattern> </encoder> </appender> <!-- 日誌記錄器，日期滾動記錄 --> <appender name="fileInfoApp" class="ch.qos.logback.core.rolling.RollingFileAppender"> <!-- 正在記錄的日誌檔案的路徑及檔名 --> <!-- <file>${LOG_PATH}/warn/log_warn.log</file> --> <!-- 日誌記錄器的滾動策略，按日期，按大小記錄 --> <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy"> <!-- 歸檔的日誌檔案的路徑，例如今天是2013-12-21日誌，當前寫的日誌檔案路徑為file節點指定，可以將此檔案與file指定檔案路徑設定為不同路徑，從而將當前日誌檔案或歸檔日誌檔案置不同的目錄。 而2013-12-21的日誌檔案在由fileNamePattern指定。%d{yyyy-MM-dd}指定日期格式，%i指定索引 --> <fileNamePattern>app_log/log/log-error-%d{yyyy-MM-dd}.%i.log</fileNamePattern> <!-- 表示只保留最近30天的日誌，以防止日誌填滿整個磁碟空間。--> <maxHistory>30</maxHistory> <!--用來指定日誌檔案的上限大小，例如設定為1GB的話，那麼到了這個值，就會刪除舊的日誌。--> <totalSizeCap>1GB</totalSizeCap> <!-- 除按日誌記錄之外，還配置了日誌檔案不能超過2M，若超過2M，日誌檔案會以索引0開始，命名日誌檔案，例如log-error-2013-12-21.0.log --> <timeBasedFileNamingAndTriggeringPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP"> <maxFileSize>2MB</maxFileSize> </timeBasedFileNamingAndTriggeringPolicy> </rollingPolicy> <!-- 追加方式記錄日誌 --> <append>true</append> <!-- 日誌檔案的格式 --> <encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder"> <pattern>===%d{yyyy-MM-dd HH:mm:ss.SSS} %-5level %logger Line:%-3L - %msg%n</pattern> <charset>utf-8</charset> </encoder> <!-- 此日誌檔案只記錄war級別的 --> <filter class="ch.qos.logback.classic.filter.LevelFilter"> <!-- 只保留error日誌 --> <!-- level:debug,info,warn,error --> <level>ERROR</level> <onMatch>ACCEPT</onMatch> <onMismatch>DENY</onMismatch> </filter> </appender> <!-- root節點要放到appender之後 --> <root level="INFO"> <appender-ref ref="STDOUT" /> <appender-ref ref="fileInfoApp" /> </root> </configuration>
3.新增控制器
package top.ytheng.demo.controller; import org.slf4j.Logger; import org.slf4j.LoggerFactory; import org.springframework.web.bind.annotation.GetMapping; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RestController; @RestController @RequestMapping("/api/v1/log") public class LogController { private Logger logger = LoggerFactory.getLogger(this.getClass()); @GetMapping("/test") public Object test() { logger.debug("this is debug level"); logger.info("this is info level"); logger.warn("this is warn level"); logger.error("this is error level"); return "success"; } }
4.新增啟動類
package top.ytheng.demo; import org.springframework.boot.autoconfigure.SpringBootApplication; @SpringBootApplication //等於下面3個 //@SpringBootConfiguration //@EnableAutoConfiguration //@ComponentScan public class DemoApplication { public static void main(String[] args) { SpringApplication.run(DemoApplication.class, args); } }
