访问日志拦截器

加入 maven 依赖

<dependency>
    <groupId>ch.qos.logback</groupId>
    <artifactId>logback-classic</artifactId>
    <version>1.2.3</version>
</dependency>

加入打包

在 resources 包下面增加 logback.xml 配置

<?xml version="1.0" encoding="UTF-8" ?>
<configuration>
  <appender name="console" class="ch.qos.logback.core.ConsoleAppender">
    <encoder>
      <!--10 代表包名最大允许的长度-->
      <pattern>[%thread] %d %level %logger{10} - %msg%n</pattern>
    </encoder>
  </appender>
  <!--RollingFileAppender: 按天滚动输出的日志文件-->
  <appender name="accessHistoryLog" class="ch.qos.logback.core.rolling.RollingFileAppender">
    <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
      <!--日志文件保存位置-->
      <filenamePattern>/var/log/hello-spring/history.%d.log</filenamePattern>
    </rollingPolicy>
    <encoder>
      <pattern>[%thread] %d %level %logger{10} - %msg%n</pattern>
    </encoder>
  </appender>
    <!--root 最低级别日志输出, 引用 console 格式-->
    <root level="debug">
        <appender-ref ref="console"/>
    </root>
    <!--设置中类产生的日志，都会使用该设置所描述的规则
    additivity:false 表示只会向指定的输出方式输出，否则也会向 console 输出-->
    <logger name="com.ylq.springmvc.interceptor.AccessHistoryInterceptor" level="INFO" additivity="false"/>
</configuration>/>

response.setContentType("text/html;charset=utf-8");

编写拦截类

public class AccessHistoryInterceptor implements HandlerInterceptor {
    private Logger logger = LoggerFactory.getLogger(AccessHistoryInterceptor.class);

    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
        StringBuilder log = new StringBuilder();
        log.append(request.getRemoteAddr());
        log.append("|");
        log.append(request.getRequestURL());
        log.append("|");
        log.append(request.getHeader("user-agent"));
        logger.info(log.toString());
        return true;
    }
}

拦截器配置增加

<mvc:interceptor>
  <mvc:mapping path="/**"/>
  <mvc:exclude-mapping path="/resources/**"/>
  <bean class="com.ylq.springmvc.interceptor.AccessHistoryInterceptor"/>
</mvc:interceptor>
