1.SpringBoot中通過AOP整合日志檔案
1.匯入相關的依賴
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter</artifactId>
<exclusions> <!-- 去掉springboot自帶的日志,不然會沖突 -->
<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 解決沖突-->
<!--<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>

</dependencies>
2.log4j2 日志檔案
<?xml version="1.0" encoding="UTF-8"?>
<!--日志級別以及優先級排序: OFF > FATAL > ERROR > WARN > INFO > DEBUG > TRACE > ALL -->
<!--Configuration 后面的 status 用于設定 log4j2 自身內部的資訊輸出，可以不設定，當設定成 trace 時，可以看到 log4j2 內部各種詳細輸出-->
<configuration status="INFO">
<!--先定義所有的 appender-->
<appenders>
<!--輸出日志資訊到控制臺-->
<console name="Console" target="SYSTEM_OUT">
<!--控制日志輸出的格式-->
<PatternLayout pattern="%d{yyyy-MM-dd HH:mm:ss.SSS} [%t] %-5level %logger{36} - %msg%n"/>
</console>
</appenders>
<!--然后定義 logger，只有定義 logger 并引入的 appender，appender 才會生效-->
<!--root：用于指定專案的根日志，如果沒有單獨指定 Logger，則會使用 root 作為默認的日志輸出-->
<loggers>
<root level="info">
<appender-ref ref="Console"/>
</root>
</loggers>
</configuration>
3.dao層的介面以及實作類
檔案路徑：com.dzj.dao.Userdao.java
package com.dzj.dao;
public interface Userdao {
void add();
void update();
void delete();
void query();
}
檔案路徑：com.dzj.dao.UserDaoImpl.java
package com.dzj.dao;
import org.springframework.stereotype.Service;
@Service
public class UserDaoImpl implements Userdao {
@Override
public void add() {
System.out.println("執行了添加方法...");
}
@Override
public void update() {
System.out.println("執行了修改方法...");
}
@Override
public void delete() {
System.out.println("執行了洗掉方法...");
}
@Override
public void query() {
System.out.println("執行了查找方法...");
}
}
4.Service層業務實作類
檔案路徑：com.dzj.service.UserService.java
package com.dzj.service;
import com.dzj.dao.UserDaoImpl;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
@Service
public class UserService {
@Autowired
UserDaoImpl userDao;
public void add(){
userDao.add();
}
public void update(){
userDao.update();
}
public void delete(){
userDao.delete();
}
public void query(){
userDao.query();
}
}
5.Controller層介面控制類
檔案路徑：com.dzj.controller.UserController.java
package com.dzj.controller;
import com.dzj.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
@Controller
@ResponseBody
public class UserController {
@Autowired
UserService userService;
@RequestMapping("/test")
public String userTest(){
userService.add();
return "chenggongle...";
}
}
6.撰寫業務類增強類，加入一個日志檔案記錄
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.ServletRequestAttributes;
import javax.servlet.http.HttpServletRequest;
import java.util.Arrays;
@Component
@Aspect
public class AdviceMethod {
private static final Logger log = LoggerFactory.getLogger(AdviceMethod.class);
@Pointcut("execution(public * com.dzj.service.UserService.*(..))")
public void webLog(){}
@Before("webLog()")
public void before(JoinPoint joinPoint){
//這個RequestContextHolder是Springmvc提供來獲得請求的東西
RequestAttributes requestAttributes = RequestContextHolder.getRequestAttributes();
HttpServletRequest request = ((ServletRequestAttributes)requestAttributes).getRequest();
// 記錄下請求內容
log.info("################URL : " + request.getRequestURL().toString());//獲取請求的地址
log.info("################HTTP_METHOD : " + request.getMethod());//獲取請求的方法
log.info("################IP : " + request.getRemoteAddr());
log.info("################THE ARGS OF THE CONTROLLER : " + Arrays.toString(joinPoint.getArgs()));
/**
* getSignature().getDeclaringTypeName() 是獲取包+類名的
* joinPoint.getSignature.getName() 獲取了方法名
* joinPoint.getTarget() 回傳的是需要加強的目標類的物件
* joinPoint.getThis()) 回傳的是經過加強后的代理類的物件
*/
log.info("################CLASS_METHOD : " + joinPoint.getSignature().getDeclaringTypeName() + "." + joinPoint.getSignature().getName());
log.info("################TARGET: " + joinPoint.getTarget());
log.info("################THIS: " + joinPoint.getThis());
System.out.println("方法執行之前...");
}
@After("webLog()")
public void after(){
System.out.println("方法執行之后...");
}
}
7.運行測驗，查看結果
啟動主啟動器類，在瀏覽器中輸入http://localhost:8080/test，查看控制臺輸出資訊
搞定，結束...
