一、依赖
<!-- Spring集成日志包 --> <dependency> <groupId>ch.qos.logback</groupId> <artifactId>logback-classic</artifactId> </dependency> <dependency> <groupId>ch.qos.logback</groupId> <artifactId>logback-core</artifactId> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-api</artifactId> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>jcl-over-slf4j</artifactId> </dependency> <dependency> <groupId>org.logback-extensions</groupId> <artifactId>logback-ext-spring</artifactId> </dependency> <dependency> <groupId>commons-logging</groupId> <artifactId>commons-logging</artifactId> </dependency>二、日志文件
在resource -- profiles 文件下新建logback.xml文件
<?xml version="1.0" encoding="UTF-8"?> <configuration scan="true" scanPeriod="60 seconds" debug="false"> <property name="project_name" value="com.demo" /> <contextName>${project_name}</contextName> <property name="file_path" value="/logs/${project_name}"/> <!-- 日志输出源，输出日志到文件，不满足某个条件时将日志输出到另一个文件 --> <appender name="ERROR_FILE" class="ch.qos.logback.core.rolling.RollingFileAppender"> <file>${file_path}/error.log</file> <!-- 日志记录器的滚动策略，按日期，按大小记录 --> <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy"> <!-- 每天日志归档路径以及格式 --> <fileNamePattern>${file_path}/log-error-%d{yyyy-MM-dd}.%i.log</fileNamePattern> <timeBasedFileNamingAndTriggeringPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP"> <maxFileSize>100MB</maxFileSize> </timeBasedFileNamingAndTriggeringPolicy> <!--日志文件保留天数--> <maxHistory>30</maxHistory> </rollingPolicy> <!-- 日志格式化器 --> <encoder> <!--格式化输出：%d表示日期，%thread表示线程名，%-5level：级别从左显示5个字符宽度%msg：日志消息，%n是换行符--> <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{50} - %msg%n</pattern> </encoder> <!-- 此日志文件只记录info级别的 --> <filter class="ch.qos.logback.classic.filter.LevelFilter"> <level>ERROR</level> <onMatch>ACCEPT</onMatch> <onMismatch>DENY</onMismatch> </filter> </appender> <!-- 时间滚动输出 level为 INFO 日志 --> <appender name="INFO_FILE" class="ch.qos.logback.core.rolling.RollingFileAppender"> <file>${file_path}/info.log</file> <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy"> <fileNamePattern>${file_path}/log-info-%d{yyyy-MM-dd}.%i.log</fileNamePattern> <timeBasedFileNamingAndTriggeringPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP"> <maxFileSize>100MB</maxFileSize> </timeBasedFileNamingAndTriggeringPolicy> <maxHistory>30</maxHistory> </rollingPolicy> <encoder> <!--格式化输出：%d表示日期，%thread表示线程名，%-5level：级别从左显示5个字符宽度%msg：日志消息，%n是换行符--> <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{50} - %msg%n</pattern> </encoder> <!-- 此日志文件只记录info级别的 --> <filter class="ch.qos.logback.classic.filter.LevelFilter"> <level>INFO</level> <onMatch>ACCEPT</onMatch> <onMismatch>DENY</onMismatch> </filter> </appender> <!-- 时间滚动输出 level为 DEBUG 日志 --> <appender name="DEBUG_FILE" class="ch.qos.logback.core.rolling.RollingFileAppender"> <file>${file_path}/debug.log</file> <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy"> <fileNamePattern>${file_path}/log-debug-%d{yyyy-MM-dd}.%i.log</fileNamePattern> <timeBasedFileNamingAndTriggeringPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP"> <maxFileSize>100MB</maxFileSize> </timeBasedFileNamingAndTriggeringPolicy> <maxHistory>30</maxHistory> </rollingPolicy> <encoder> <!--格式化输出：%d表示日期，%thread表示线程名，%-5level：级别从左显示5个字符宽度%msg：日志消息，%n是换行符--> <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{50} - %msg%n</pattern> </encoder> <!-- 此日志文件只记录info级别的 --> <filter class="ch.qos.logback.classic.filter.LevelFilter"> <level>DEBUG</level> <onMatch>ACCEPT</onMatch> <onMismatch>DENY</onMismatch> </filter> </appender> <!-- 根日志输出器：级别TRACE、DEBUG、INFO、WARN、ERROR、ALL、OFF --> <root level="ERROR"> <appender-ref ref="ERROR_FILE" /> </root> <root level="INFO"> <appender-ref ref="INFO_FILE" /> </root> <root level="DEBUG"> <appender-ref ref="DEBUG_FILE" /> </root> <!--myibatis log configure--> <logger name="com.apache.ibatis" level="TRACE"/> <logger name="java.sql.Connection" level="DEBUG"/> <logger name="java.sql.Statement" level="DEBUG"/> <logger name="java.sql.PreparedStatement" level="DEBUG"/> <logger name="com.cherry.shop" level="DEBUG"/> </configuration>三、代码编写
需要输出日志的类
@Controller @RequestMapping("/jobSummary") public class JobSummaryController { // 为该类打上日志 private final static Logger logger = LoggerFactory.getLogger(JobSummaryController.class); @Autowired private JobSummaryService jobSummaryService; /** * 修改工作总结 * @param params * @param r * @return */ @RequestMapping("/insertJobSummary") @ResponseBody public Result insertJobSummary(@Valid @RequestBody JobSummaryDto params, BindingResult r){ try{ // 参数检测+ if(r.hasErrors()){ return Results.error(); } if(!StringUtils.isBlank(params.getId())){ // 修改 JobSummary jobSummary = jobSummaryService.selectById(params.getId()); jobSummary.setJobContent(params.getJobContent()); jobSummaryService.updateById(jobSummary); } return Results.opOk(); } catch (Exception e) { logger.error("修改工作总结失败！params："+params.toString(),e); return Results.updateError(); } } }四、日志输出
在定义的目录下生成了三个日志文件：
其中我修改了工作总结，日志记录在debug文件里：
