二、日志相关配置

🖊 新增会员模块（member）

@SpringBootApplication
public class TrainMemberApplication {private static final Logger LOG = LoggerFactory.getLogger(TrainMemberApplication.class);@SuppressWarnings("all")public static void main(String[] args) {ConfigurableApplicationContext ioc = SpringApplication.run(TrainMemberApplication.class, args);ConfigurableEnvironment env = ioc.getEnvironment();// http://www.network-science.de/ascii/LOG.info("\n      _                        _                 \n" +"     | |                      | |                \n" +"     | | __ _  __ _  ___   ___| |__   __ _ _ __  \n" +" _   | |/ _` |/ _` |/ _ \\ / __| '_ \\ / _` | '_ \\ \n" +"| |__| | (_| | (_| | (_) | (__| | | | (_| | | | |\n" +" \\____/ \\__,_|\\__, |\\___/ \\___|_| |_|\\__,_|_| |_|\n" +"               __/ |                             \n" +"              |___/  \n" +"会员模块启动成功(*^_^*) \n" +"BaseURL: http://{}:{}{}", env.getProperty("server.address"),env.getProperty("server.port"),env.getProperty("server.servlet.context-path"));}
}

📕 logback-spring.xml：

<?xml version="1.0" encoding="UTF-8"?>
<configuration><!-- 修改一下路径--><property name="PATH" value="./log/member"/><appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender"><encoder><!--<Pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} %highlight(%-5level) %blue(%-50logger{50}:%-4line) %thread %green(%-18X{LOG_ID}) %msg%n</Pattern>--><Pattern>%d{mm:ss.SSS} %highlight(%-5level) %blue(%-30logger{30}:%-4line) %thread %green(%-18X{LOG_ID})%msg%n</Pattern></encoder></appender><appender name="TRACE_FILE" class="ch.qos.logback.core.rolling.RollingFileAppender"><file>${PATH}/trace.log</file><rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy"><FileNamePattern>${PATH}/trace.%d{yyyy-MM-dd}.%i.log</FileNamePattern><timeBasedFileNamingAndTriggeringPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP"><maxFileSize>10MB</maxFileSize></timeBasedFileNamingAndTriggeringPolicy></rollingPolicy><layout><pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} %-5level %-50logger{50}:%-4line %green(%-18X{LOG_ID}) %msg%n</pattern></layout></appender><appender name="ERROR_FILE" class="ch.qos.logback.core.rolling.RollingFileAppender"><file>${PATH}/error.log</file><rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy"><FileNamePattern>${PATH}/error.%d{yyyy-MM-dd}.%i.log</FileNamePattern><timeBasedFileNamingAndTriggeringPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP"><maxFileSize>10MB</maxFileSize></timeBasedFileNamingAndTriggeringPolicy></rollingPolicy><layout><pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} %-5level %-50logger{50}:%-4line %green(%-18X{LOG_ID}) %msg%n</pattern></layout><filter class="ch.qos.logback.classic.filter.LevelFilter"><level>ERROR</level><onMatch>ACCEPT</onMatch><onMismatch>DENY</onMismatch></filter></appender><root level="ERROR"><appender-ref ref="ERROR_FILE"/></root><root level="TRACE"><appender-ref ref="TRACE_FILE"/></root><root level="INFO"><appender-ref ref="STDOUT"/></root>
</configuration>

3、AOP 打印日志

📕 maven 依赖

 <dependency><groupId>com.alibaba</groupId><artifactId>fastjson</artifactId><version>1.2.70</version></dependency><dependency><groupId>cn.hutool</groupId><artifactId>hutool-all</artifactId><version>5.6.0</version></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-aop</artifactId><version>3.0.0</version>
</dependency>

📕 切面类

@Aspect
@Component
public class LogAspect {private final static Logger LOG = LoggerFactory.getLogger(LogAspect.class);@Pointcut("execution(public * com.jagochan..*Controller.*(..))")public void controllerPointcut() {}@Before("controllerPointcut()")public void doBefore(JoinPoint joinPoint) {// 开始打印请求日志ServletRequestAttributes attributes = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();HttpServletRequest request = Objects.requireNonNull(attributes).getRequest();Signature signature = joinPoint.getSignature();String name = signature.getName();// 打印请求信息LOG.info("------------- 开始 -------------");LOG.info("请求地址: {} {}", request.getRequestURL().toString(), request.getMethod());LOG.info("类名方法: {}.{}", signature.getDeclaringTypeName(), name);LOG.info("远程地址: {}", request.getRemoteAddr());// 打印请求参数Object[] args = joinPoint.getArgs();// 排除特殊类型的参数，如文件类型Object[] arguments = new Object[args.length];for (int i = 0; i < args.length; i++) {if (args[i] instanceof ServletRequest|| args[i] instanceof ServletResponse|| args[i] instanceof MultipartFile) {continue;}arguments[i] = args[i];}// 排除字段，敏感字段或太长的字段不显示：身份证、手机号、邮箱、密码等String[] excludeProperties = {};PropertyPreFilters filters = new PropertyPreFilters();PropertyPreFilters.MySimplePropertyPreFilter excludeFilter = filters.addFilter();excludeFilter.addExcludes(excludeProperties);LOG.info("请求参数: {}", JSONObject.toJSONString(arguments, excludeFilter));}@Around("controllerPointcut()")public Object doAround(ProceedingJoinPoint proceedingJoinPoint) throws Throwable {long startTime = System.currentTimeMillis();Object result = proceedingJoinPoint.proceed();// 排除字段，敏感字段或太长的字段不显示：身份证、手机号、邮箱、密码等String[] excludeProperties = {};PropertyPreFilters filters = new PropertyPreFilters();PropertyPreFilters.MySimplePropertyPreFilter excludeFilter = filters.addFilter();excludeFilter.addExcludes(excludeProperties);LOG.info("返回结果: {}", JSONObject.toJSONString(result, excludeFilter));LOG.info("------------- 结束 耗时：{} ms -------------", System.currentTimeMillis() - startTime);return result;}}

4、下载开源前端后台管理系统

# clone the project
git clone https://github.com/PanJiaChen/vue-admin-template.git# enter the project directory
cd vue-admin-template# install dependency
npm install# develop
npm run dev

5、添加网关模块

  <dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-starter-gateway</artifactId></dependency>

📕 TrainGatewayApplication.java

spring:cloud:gateway:routes:- id: memberuri: http://127.0.0.1:5200predicates:- Path=/member/**

📕 添加JVM参数，让请求有日志

-Dreactor.netty.http.server.accessLogEnabled=true

6、集成数据库和mp

(1) 添加驱动和mp依赖

   <!-- MySql驱动 --><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId><version>8.0.22</version></dependency><!-- MyBatisPlus --><dependency><groupId>com.baomidou</groupId><artifactId>mybatis-plus-boot-starter</artifactId><version>3.5.3</version></dependency>

(2) 数据库配置

spring:application:name: train-memberdatasource:url: jdbc:mysql://gqok.xyz:3306/unlimited_train?serverTimezone=Asia/Shanghai&useUnicode=true&characterEncoding=utf8&useSSL=falseusername: rootpassword: rootdriver-class-name: com.mysql.cj.jdbc.Driver

(3) 使用MybatisPlus

• MemberMapper 继承 BaseMapper
• MemberService 继承 IService
• MemberServiceImpl 继承 ServiceImpl

7、加密 yaml 文件中的内容

(1) 依赖

  <dependency><groupId>com.github.ulisesbocchio</groupId><artifactId>jasypt-spring-boot-starter</artifactId><version>2.1.0</version></dependency>

(2) 敏感信息加密

/*** 对配置文件中的敏感信息做加密处理*/
public class JasyptUtil {public static void main(String[] args) {StandardPBEStringEncryptor stringEncryptor = new StandardPBEStringEncryptor();// 设置加密密钥（该密钥用于解密和加密）// 项目启动的时候要在JVM参数中配置stringEncryptor.setPassword("thePwdIsUsedToEncrypt");// 设置加密算法stringEncryptor.setAlgorithm("PBEWithMD5AndDES");// 对username进行加密处理, 加密后的字符串是密文, 要放到配置文件中String username = stringEncryptor.encrypt("username");System.out.println("🍀 username = " + username);// 对password进行加密处理, 加密后的字符串是密文, 要放到配置文件中String pwd = stringEncryptor.encrypt("password");System.out.println("🍀 pwd = " + pwd);}
}

(3) 把(2)中的加密字符串放到配置文件中

📕 加密字符串需要用 ENC() 包裹
🖊 如：ENC(thisIsASecret)

spring:application:name: train-memberdatasource:url: jurl: jdbc:mysql://happy.xyz:3306/unlimited_train?serverTimezone=Asia/Shanghai&useUnicode=true&characterEncoding=utf8&useSSL=falseusername: ENC(WWGfxe/CgyS4YnyCIZJvuXHbBn5D2y3XWlTmlKMA0mc=)password: ENC(8LARw5u9e9MkXTh/ZoxuFE8bIoUjwVMc/uDoKnriaZo=)driver-class-name: com.mysql.cj.jdbc.Driverjasypt:encryptor:algorithm: PBEWithMD5AndDES

🖊 启动项目的时候要加 JVM 参数，配置解密密钥：
-Djasypt.encryptor.password=password

🖊 添加启动注解：@EnableEncryptableProperties
