logback日志配置

logback.xml文件

<configuration dabug="false">
    <appender name="FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">
         <!--日志生成位置-->
        <File>E:/Log/SSM4.3.7.log</File>
        <!--日志生成格式-->
        <encoder>
            <Pattern>%d %5p [%t] %c:%L - %m%n</Pattern>
        </encoder>
        <!--日志生成每天打包压缩一次-->
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <FileNamePattern>E:/Log/SSM4.3.7.log%d{yyyy-MM-dd}.gz</FileNamePattern> 
        </rollingPolicy>
    </appender>

      <!--日志生成级别-->
    <root level="debug">
        <appender-ref ref="FILE"></appender-ref>
    </root>
    <!--需要生成日志的包-->
    <logger name="com.ssm" level="debug"/>
    <logger name="org" level="error"/>

</configuration>

Controller和日志相关主要代码

    //日志
     final Logger logger = LoggerFactory.getLogger(StudentController.class);
    @Autowired  //自动装配ByType
    @Resource(type=StudentService.class)  //自动装配ByName 使用name属性时用byname 使用type时用bytype
    //@Qualifier  //ByNmame注入
    private StudentService studentServices;

    @RequestMapping("/register")
    public String register(Student student){    
        //注册方法
        try {
            studentServices.addStu(student);
            //ModelAndView mv = new ModelAndView();
            //其底层执行的是request.setAttribute()方法
        } catch (Exception e) {
            //把异常添加到日志中
            logger.error(e.getMessage());
        }
        return "jsp/ok";
    }
