SpringCloud（第 048 篇）使用AOP统一处理Web请求日志

-

一、大致介绍 
讯享网1、AOP是Spring框架中的一个重要内容，它通过对既有程序定义一个切入点，然后在其前后切入不同的执行内容，比如常见的有：打开数据库连接/关闭数据库连接、打开事务/关闭事务、记录日志等； 2、基于AOP不会破坏原来程序逻辑，因此它可以很好的对业务逻辑的各个部分进行隔离，从而使得业务逻辑各部分之间的耦合度降低，提高程序的可重用性，同时提高了开发的效率。
二、实现步骤 2.1 添加 maven 引用包 
<?xml version=“1.0” encoding=“UTF-8”?> 
 
   
 
  
    
   http://maven.apache.org/POM/4.0.0” 
  
    
   
  
    
  
讯享网 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <artifactId>springms-aop-weblog</artifactId> <version>1.0-SNAPSHOT</version> <packaging>jar</packaging> <parent> <groupId>com.springms.cloud</groupId> <artifactId>springms-spring-cloud</artifactId> <version>1.0-SNAPSHOT</version> </parent> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-data-jpa</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>com.h2database</groupId> <artifactId>h2</artifactId> <scope>runtime</scope> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-data-solr</artifactId> </dependency> </dependencies>
2.2 添加应用配置文件（springms-aop-weblogsrcmainresourcesapplication.yml） 
server: port: 8350 spring: application: 
讯享网name: springms-aop-weblog #全部小写 
 jpa: 
generate-ddl: false show-sql: true hibernate: ddl-auto: none 
 datasource: 
讯享网platform: h2 schema: classpath:schema.sql data: classpath:data.sql</pre> 
 2.3 添加 H2 数据库脚本（springms-aop-weblogsrcmainresourcesschema.sql）
drop table user if exists; CREATE TABLE USER( 
讯享网id BIGINT GENERATED by default as identity, username VARCHAR(40), name VARCHAR(20), age int(3), balance DECIMAL(10, 2), PRIMARY KEY(id) 
 );
 2.4 插入 H2 数据库一些初始化数据（springms-aop-weblogsrcmainresourcesdata.sql） 
INSERT into user (id, username, name, age, balance) values (1, “user1”, “张三”, 20, 100.00); INSERT into user (id, username, name, age, balance) values (2, “user2”, “李四”, 22, 100.00); INSERT into user (id, username, name, age, balance) values (3, “user3”, “王五”, 24, 100.00); INSERT into user (id, username, name, age, balance) values (4, “user4”, “赵六”, 26, 100.00); INSERT into user (id, username, name, age, balance) values (5, “user5”, “李逵”, 27, 100.00); INSERT into user (id, username, name, age, balance) values (6, “user6”, “张远”, 10, 100.00); INSERT into user (id, username, name, age, balance) values (7, “user7”, “迪拜”, 60, 100.00); INSERT into user (id, username, name, age, balance) values (8, “user8”, “哈士奇”, 40, 100.00); INSERT into user (id, username, name, age, balance) values (9, “user9”, “关羽”, 30, 100.00); 
 2.5 添加访问底层数据模型的DAO接口（springms-aop-weblogsrcmainjavacomspringmscloudrepositoryUserRepository.java） 
讯享网package com.springms.cloud.repository; import com.springms.cloud.entity.User; import org.springframework.data.jpa.repository.JpaRepository; import org.springframework.stereotype.Repository; @Repository public interface UserRepository extends JpaRepository 
   
     
   
     { 
    }
 2.6 添加实体用户类User（springms-aop-weblogsrcmainjavacomspringmscloudentityUser.java） 
package com.springms.cloud.entity; import java.math.BigDecimal; import javax.persistence.Column; import javax.persistence.Entity; import javax.persistence.GeneratedValue; import javax.persistence.GenerationType; import javax.persistence.Id; @Entity public class User { @Id @GeneratedValue(strategy = GenerationType.AUTO) private Long id; @Column private String username; @Column private String name; @Column private Short age; @Column private BigDecimal balance; public Long getId() { 
讯享网return this.id; 
 } public void setId(Long id) { 
this.id = id; 
 } public String getUsername() { 
讯享网return this.username; 
 } public void setUsername(String username) { 
this.username = username; 
 } public String getName() { 
讯享网return this.name; 
 } public void setName(String name) { 
this.name = name; 
 } public Short getAge() { 
讯享网return this.age; 
 } public void setAge(Short age) { 
this.age = age; 
 } public BigDecimal getBalance() { 
讯享网return this.balance; 
 } public void setBalance(BigDecimal balance) { 
this.balance = balance; 
 } }
 2.7 添加Web层日志切面@Order(1)（springms-aop-weblogsrcmainjavacomspringmscloudcontrollerUserController.java） 
讯享网package com.springms.cloud.aop; import org.apache.log4j.Logger; import org.aspectj.lang.JoinPoint; import org.aspectj.lang.annotation.AfterReturning; import org.aspectj.lang.annotation.Aspect; import org.aspectj.lang.annotation.Before; import org.aspectj.lang.annotation.Pointcut; import org.springframework.core.annotation.Order; import org.springframework.stereotype.Component; import org.springframework.web.context.request.RequestContextHolder; import org.springframework.web.context.request.ServletRequestAttributes; import javax.servlet.http.HttpServletRequest; import java.util.Arrays; / 实现AOP的切面主要有以下几个要素： 使用@Aspect注解将一个java类定义为切面类 使用@Pointcut定义一个切入点，可以是一个规则表达式，比如下例中某个package下的所有函数，也可以是一个注解等。 根据需要在切入点不同位置的切入内容 使用@Before在切入点开始处切入内容 使用@After在切入点结尾处切入内容 使用@AfterReturning在切入点return内容之后切入内容（可以用来对处理返回值做一些加工处理） 使用@Around在切入点前后切入内容，并自己控制何时执行切入点自身的内容 使用@AfterThrowing用来处理当切入内容部分抛出异常之后的处理逻辑 使用@Order(i)注解来标识切面的优先级。i的值越小，优先级越高 / / 执行日志顺序： 2017-10-19 20:22:35.810 INFO 9014 — [nio-8350-exec-1] WebLogHeadAspect : (Order(1)) (doBefore) URL : http://localhost:8350/simple/1 2017-10-19 20:22:35.810 INFO 9014 — [nio-8350-exec-1] WebLogHeadAspect : (Order(1)) (doBefore) HTTP_METHOD : GET 2017-10-19 20:22:35.810 INFO 9014 — [nio-8350-exec-1] WebLogHeadAspect : (Order(1)) (doBefore) IP : 127.0.0.1 2017-10-19 20:22:35.811 INFO 9014 — [nio-8350-exec-1] WebLogHeadAspect : (Order(1)) (doBefore) CLASS_METHOD : com.springms.cloud.controller.SimpleProviderUserAopWebLogController.findById 2017-10-19 20:22:35.811 INFO 9014 — [nio-8350-exec-1] WebLogHeadAspect : (Order(1)) (doBefore) ARGS : [1] 2017-10-19 20:22:35.811 INFO 9014 — [nio-8350-exec-1] com.springms.cloud.aop.WebLogFiveAspect : (Order(5))============== (doBefore) URL : http://localhost:8350/simple/1 2017-10-19 20:22:35.811 INFO 9014 — [nio-8350-exec-1] com.springms.cloud.aop.WebLogFiveAspect : (Order(5))============== (doBefore) HTTP_METHOD : GET 2017-10-19 20:22:35.811 INFO 9014 — [nio-8350-exec-1] com.springms.cloud.aop.WebLogFiveAspect : (Order(5))============== (doBefore) IP : 127.0.0.1 2017-10-19 20:22:35.811 INFO 9014 — [nio-8350-exec-1] com.springms.cloud.aop.WebLogFiveAspect : (Order(5))============== (doBefore) CLASSMETHOD : com.springms.cloud.controller.SimpleProviderUserAopWebLogController.findById 2017-10-19 20:22:35.811 INFO 9014 — [nio-8350-exec-1] com.springms.cloud.aop.WebLogFiveAspect : (Order(5))============== (doBefore) ARGS : [1] Hibernate: select user0.id as id1_00, user0_.age as age2_00, user0_.balance as balance3_00, user0_.name as name4_00, user0_.username as username5_00 from user user0_ where user0_.id=? 2017-10-19 20:22:35.853 INFO 9014 — [nio-8350-exec-1] com.springms.cloud.aop.WebLogFiveAspect : (Order(5))============== (doAfterReturning) RESPONSE : User@ 2017-10-19 20:22:35.853 INFO 9014 — [nio-8350-exec-1] com.springms.cloud.aop.WebLogFiveAspect : (Order(5))============== (doAfterReturning) SPEND TIME : 42 2017-10-19 20:22:35.853 INFO 9014 — [nio-8350-exec-1] WebLogHeadAspect : (Order(1)) (doAfterReturning) RESPONSE : User@ 2017-10-19 20:22:35.853 INFO 9014 — [nio-8350-exec-1] WebLogHeadAspect : (Order(1)) (doAfterReturning) SPEND TIME : 43 总结：doBefore 方法先从优先级到低优先级依次执行完，然后 doAfterReturning 方法从低优先级到高优先级依次执行完；也就是进入从高到低，出来从低到高； / /
