1.导入相关的依赖

<dependencies>     <dependency>        <groupid>org.springframework.boot</groupid>        <artifactid>spring-boot-starter</art所得税汇算清缴ifactid>        <exclusions> <!-- 去掉springboot自带的日志,不然会冲突 -->            <exclusion>                <groupid>org.springframework.boot</groupid>                <artifactid>spring-boot-starter-logging</artifactid>            </exclusion>        </exclusions>    </dependency>     <dependency>        <groupid>org.apache.logging.log4j</groupid>        <artifactid>log4j-core</artifactid>    </dependency>    <!-- log4j-api -->    <dependency>        <groupid>org.apache.logging.log4j</groupid>        <artifactid>log4j-api</artifactid>    </dependency>    <!-- log4j-slf4j-impl -->    <dependency>        <groupid>org.apache.logging.log4j</groupid>        <artifactid>log4j-slf4j-impl</artifactid>    </dependency>    <!-- slf4j-api -->    <dependency>        <groupid>org.slf4j</groupid>        <artifactid>slf4j-api</artifactid>    </dependency>    <!-- slf4j-simple 解决冲突-->    <!--<dependency>-->        <!--<groupid>org.slf4j</groupid>-->        <!--<artifactid>slf4j-simple</artifactid>-->    <!--</dependency>-->     <dependency>        <groupid>org.springframework.boot</groupid>        <artifactid>spring-boot-starter-aop</artifactid>    </dependency>     <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>    <d运动会加油稿件ependency>        <groupid>log4j</groupid>        <artifactid>log4j</artifactid>        <version>1.2.12</version>    </dependency></dependencies>

2.log4j2 日志文件

<?xml version="1.0" encoding="utf-8"?><!--日志级别以及优先级排序: off > fatal > error > warn > info > debug > trace > all --><!--configuration 后面的 status 用于设置 log4j2 自身内部的信息输出，可以不设置，当设置成 trace 时，可以看到 log4j2 内部各种详细输出--><configuration status="info">    <!--先定义所有的 appender-->    <appenders>        <!--输出日志信息到控制台-->        <console name="console" target="system_out">            <!--控制日志输出的格式-->            <patternlayout pattern="%d{yyyy-mm-dd hh:mm:ss.sss} [%t] %-5level %logger{36} - %msg%n"/>        </console>    </appenders>    <!--然后定义 logger，只有定义 logger 并引入的 appender，appender 才会生效-->    <!--root：用于指定项目的根日志，如果没有单独指定 logger，则会使用 root 作为默认的日志输出-->    <loggers>        <root level="info">            <appender-ref ref="console"/>        祝福新人结婚的话</root>    </loggers></configuration>

3.dao层的接口以及实现类

文件路径：com.dzj.dao.urdao.java

package com.dzj.dao; public interface urdao {     void add();     void update();     void delete();     void query();}

文件路径：com.dzj.dao.urdaoimpl.java

package com.dzj.dao; import org.springframework.stereotype.rvice; @rvicepublic class urdaoimpl implements urdao {    @override    public void add() {        system.out.println("执行了添加方法...");    }     @override    public void update() {         system.out.println("执行了修改方法...");    }     @override    public void delete() {         system.out.println("执行了删除方法...");    }     @override    public void query() {         system.out.println("执行了查找方法...");    }}

4.rvice层业务实现类

文件路径：com.dzj.rvice.urrvice.java

package com.dzj.rvice; import com.dzj.dao.urdaoimpl;import org.springframework.beans.factory.annotation.autowired;import org.springframework.stereotype.rvice; @rvicepublic class urrvice {     @autowired    urdaoimpl urdao;     public void add(){        urdao.add();    }    public void update(){        urdao.update();    }    public void delete(){        urdao.delete();    }    public void query(){        urdao.query();    }}

5.controller层接口控制类

文件路径：com.dzj.controller.urcontroller.java

package com.dzj.controller; import com.dzj.rvice.urrvice;import org.springframework.beans.factory.annotation.autowired;import org.springframework.stereotype.controller;import org.springframework.web.bind.annotation.requestmapping;import org.springframework.web.bind.annotati礼仪课程培训on.responbody; @controller@responbodypublic class urcontroller {     @autowired    urrvice urrvice;     @requestmapping("/test")    public string urtest(){         urrvice.add();        return "chenggongle...";    }}

6.编写业务类增强类，加入一个日志文件记录

package com.dzj.advice; import org.aspectj.lang.joinpoint;import org.aspectj.lang.annotation.after;import org.aspectj.lang.annotation.aspect;import org.aspectj.lang.annotation.before;import org.aspectj.lang.annotation.pointcut;import org.slf4j.logger;import org.slf4j.loggerfactory;import org.springframework.stereotype.component;import org.springframework.web.context.request.requestattributes;import org.springframework.web.context.request.requestcontextholder;import org.springframework.web.context.request.rvletrequestattributes; import javax.rvlet.http.httprvletrequest;import java.util.arrays; @component@aspectpublic class advicemethod {     private static final logger log = loggerfactory.getlogger(advicemethod.class);     @pointcut("execution(public * com.dzj.rvice.urrvice.*(..))")    public void weblog(){}     @before("weblog()")    public void before(joinpoint joinpoint){         //这个requestcontextholder是springmvc提供来获得请求的东西        requestattributes requestattributes = requestcontextholder.getrequestattributes();        httprvletrequest request = ((rvletrequestattributes)requestattributes).getrequest();         // 记录下请求内容        log.info("################url : " + request.getrequesturl().tostring());//获取请求的地址        log.info("################http_method : " + request.getmethod());//获取请求的方法        log.info("################ip : " + request.getremoteaddr());        log.info("################the args of the controller : " + arrays.tostring(joinpoint.getargs()));         /**         * getsignature().getdeclaringtypename()   是获取包+类名的         * joinpoint.getsignature.getname()  获取了方法名         * joinpoint.gettarget() 返回的是需要加强的目标类的对象         * joinpoint.getthis())  返回的是经过加强后的代理类的对象         */        log.info("################class_method : " + joinpoint.getsignature().getdeclaringtypename() + "." + joinpoint.getsignature().getname());        log.info("################target: " + joinpoint.gettarget(贵无));        log.info("################this: " + joinpoint.getthis());        system.out.println("方法执行之前...");    }     @after("weblog()")    public void after(){        system.out.println("方法执行之后...");    }}
