5.E-R图

2.架构设计(三层架构)

3.练题微服务架构搭建

1.创建一个练题微服务模块
1.创建一个maven项目

2.把src删除,只留pom.xml
2.微服务父模块的pom.xml配置
1.配置packaging为pom,指定编译版本,并统一指定SpringBoot版本,统一配置阿里云仓库,使子模块继承
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         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>

    <groupId>com.sun.club</groupId>
    <artifactId>sun-club-practice</artifactId>
    <version>1.0-SNAPSHOT</version>
    <!-- 父模块需要配置这个pom -->
    <packaging>pom</packaging>

    <properties>
        <!-- 指定编译版本 -->
        <maven.compiler.source>8</maven.compiler.source>
        <maven.compiler.target>8</maven.compiler.target>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    </properties>

    <!-- 父模块统一指定SpringBoot版本 -->
    <dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-dependencies</artifactId>
                <version>2.4.2</version>
                <!-- 下面两个配置表示导入spring-boot-dependencies的dependencyManagement的版本 -->
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>


    <!-- 阿里云仓库,在父模块中配置仓库,可以使得所有子模块自动继承这个配置,这样在多模块项目中,每个模块无需单独配置仓库信息,便于管理和维护。 -->
    <repositories>
        <repository>
            <id>central</id>
            <name>aliyun maven</name>
            <url>http://maven.aliyun.com/nexus/content/groups/public/</url>

            <releases>
                <enabled>true</enabled>
            </releases>
            <snapshots>
                <enabled>true</enabled>
            </snapshots>

    </repositories>

</project>
2.type和scope解释
1.type

<type>: 在Maven中,type元素指定了依赖项的包装类型。默认情况下,如果不指定type,Maven会假定它是一个jar文件。在你提供的示例中,type被设置为pom。这意味着被引入的依赖是一个POM类型的项目,通常用于依赖管理而非包含实际的代码库。这种类型的依赖通常用于声明一组库的版本管理,而不是作为代码库直接参与构建。

2.scope

<scope>: scope元素定义了依赖的使用范围。不同的scope值决定了依赖在项目的不同构建阶段以及不同模块间的可见性。常见的scope包括:

  • compile:默认值,表示依赖在编译阶段和运行阶段都是必需的,且会被传递到依赖的项目。
  • runtime:表示依赖不需要在编译阶段,但在运行时需要。
  • provided:表示依赖在编译和测试时需要,但在运行时不需要,因为运行环境已提供该依赖。
  • test:表示依赖仅在测试阶段需要,用于编译和运行测试代码。
  • import(正如你的例子中所用):这是一个特殊的scope,用于只在<dependencyManagement>中有效。它表示当前POM是从其他POM中导入依赖管理信息,通常用于继承和共享一组依赖定义。通过import,可以将其他项目的依赖版本管理集成到自己的项目中,从而保持依赖版本的一致性和可管理性。
3.创建一个练题微服务的api模块
1.创建一个maven项目,删除resource目录和test目录

2.创建一个common包存放Result和Page相关的
1.目录结构

2.PageInfo.java
package com.sunxiansheng.practice.api.common;

import java.util.Objects;

/**
 * Description: 分页请求的入参
 * @Author sun
 * @Create 2024/5/28 16:25

public class PageInfo {

    private Integer pageNo = 1;
    private Integer pageSize = 20;

    public Integer getPageNo() {
        return (pageNo == null || pageNo < 1) ? 1 : pageNo;
    }

    public Integer getPageSize() {
        return (pageSize == null || pageSize < 1) ? 20 : pageSize;
    }

    public PageInfo setPageNo(Integer pageNo) {
        this.pageNo = pageNo;
        return this;
    }

    public PageInfo setPageSize(Integer pageSize) {
        this.pageSize = pageSize;
        return this;
    }

    @Override
    public boolean equals(Object o) {
        if (this == o) return true;

        PageInfo pageInfo = (PageInfo) o;
        return Objects.equals(pageNo, pageInfo.pageNo) &&
                Objects.equals(pageSize, pageInfo.pageSize);
    }

    @Override

4.创建一个req和vo分别存放入参和出参实体
结构

4.创建一个server子模块
1.创建一个maven项目

2.创建一个config包,暂时先存放mybatis的东西
1.结构

4.MybatisConfiguration.java 注册两个拦截器
package com.sunxiansheng.practice.server.config.mybatis;

import com.baomidou.mybatisplus.extension.plugins.MybatisPlusInterceptor;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class MybatisConfiguration {

    @Bean
    public MybatisPlusInterceptor mybatisPlusInterceptor(){
        MybatisPlusInterceptor mybatisPlusInterceptor = new MybatisPlusInterceptor();
        mybatisPlusInterceptor.addInnerInterceptor(new MybatisPlusAllSqlLog());
        return mybatisPlusInterceptor;
    }

}

5.config下创建登录拦截器和上下文将从Header中获取logId放到ThreadLocal中
1.结构
2.GlobalConfig.java mvc的全局处理,空值不返回,存放自定义拦截器
package com.sunxiansheng.practice.server.config;

import com.fasterxml.jackson.annotation.JsonInclude;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.databind.SerializationFeature;
import com.sunxiansheng.practice.server.config.interceptor.LoginInterceptor;
import org.springframework.context.annotation.Configuration;
import org.springframework.http.converter.HttpMessageConverter;
import org.springframework.http.converter.json.MappingJackson2HttpMessageConverter;
import org.springframework.web.servlet.config.annotation.InterceptorRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurationSupport;

import java.util.List;

/**
 * mvc的全局处理
 */
@Configuration
public class GlobalConfig extends WebMvcConfigurationSupport {

    @Override
    protected void configureMessageConverters(List<HttpMessageConverter<?>> converters) {
        super.configureMessageConverters(converters);
        converters.add(mappingJackson2HttpMessageConverter());
    }
    /**
     * 自定义mappingJackson2HttpMessageConverter
     * 目前实现:空值忽略,空字段可返回
     */
    private MappingJackson2HttpMessageConverter mappingJackson2HttpMessageConverter() {
        ObjectMapper objectMapper = new ObjectMapper();
        objectMapper.configure(SerializationFeature.FAIL_ON_EMPTY_BEANS, false);
        objectMapper.setSerializationInclusion(JsonInclude.Include.NON_NULL);
        return new MappingJackson2HttpMessageConverter(objectMapper);
    }

    /**
     * 将自定义拦截器放进去
     * @param registry
     */
    @Override
    protected void addInterceptors(InterceptorRegistry registry) {
        registry.addInterceptor(new LoginInterceptor());
    }
}
3.LoginContextHolder.java ThreadLocal工具类
package com.sunxiansheng.practice.server.config.context;

import java.util.Map;
import java.util.Objects;
import java.util.concurrent.ConcurrentHashMap;

/**
 * Description: 上下文对象(ThreadLocal)
 * @Author sun
 * @Create 2024/6/15 16:27
 * @Version 1.0
 */
public class LoginContextHolder {

    // 这个ThreadLocal持有一个Map
    private static final InheritableThreadLocal<Map<String, Object>> THREAD_LOCAL
            = new InheritableThreadLocal<>();

    /**
     * 为ThreadLocal持有的Map设值
     * @param key
     * @param val
     */
    public static void set(String key, Object val) {
        Map<String, Object> map = getThreadLocalMap();
        map.put(key, val);
    }

    /**
     * 从ThreadLocal持有的Map取值
     * @param key
     * @return
     */
    public static Object get(String key) {
        Map<String, Object> map = THREAD_LOCAL.get();
        return map.get(key);
    }

    /**
     * 清除ThreadLocal
     */
    public static void remove() {
        THREAD_LOCAL.remove();
    }

    /**
     * 初始化一个ThreadLocal持有的Map,要保证这个Map是单例的
     * @return
     */
    public static Map<String, Object> getThreadLocalMap() {
        // 获取到ThreadLocal的Map
        Map<String, Object> map = THREAD_LOCAL.get();
        // 如果是空的再创建一个Map,然后放进去
        if (Objects.isNull(map)) {
            map = new ConcurrentHashMap<>();
            THREAD_LOCAL.set(map);
        }
        // 放到ThreadLocal中
        return map;
    }

    // 以下为获取用户信息的方法
    public static String getLoginId() {
        return (String) getThreadLocalMap().get("loginId");
    }


}
4.LoginInterceptor.java 登录拦截器,从Header中获取logId放到ThreadLocal
package com.sunxiansheng.practice.server.config.interceptor;

import com.sunxiansheng.practice.server.config.context.LoginContextHolder;
import org.apache.commons.lang3.StringUtils;
import org.springframework.web.servlet.HandlerInterceptor;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

/**
 * Description: 处理用户上下文的拦截器
 * @Author sun
 * @Create 2024/6/15 16:20
 * @Version 1.0
 */
public class LoginInterceptor implements HandlerInterceptor {

    /**
     * 当请求到这里了,就说明,网关已经将用户的loginId放到了Header里了
     * @param request
     * @param response
     * @param handler
     * @return
     * @throws Exception
     */
    @Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
        String loginId = request.getHeader("loginId");
        if (StringUtils.isNotBlank(loginId)) {
            // 将loginId放到ThreadLocal里面
            LoginContextHolder.set("loginId", loginId);
        }
        return true;
    }


    /**
     * 在操作结束后清除ThreadLocal,因为如果线程复用并且没清除,这个ThreadLocal还会存在,造成数据污染
     * @param request
     * @param response
     * @param handler
     * @param ex
     * @throws Exception
     */
    @Override
    public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex) throws Exception {
        LoginContextHolder.remove();
    }
}
6.创建controller包
1.结构

2.DemoController.java 测试
package com.sunxiansheng.practice.server.controller;

import lombok.extern.slf4j.Slf4j;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

/**
 * Description: 测试controller
 * @Author sun
 * @Create 2024/6/25 15:38
 * @Version 1.0
 */
@RestController
@RequestMapping("/practice/")
@Slf4j
public class DemoController {

    @RequestMapping("test")
    public String isLogin() {
        return "test";
    }

}
7.创建其余的包
1.结构

2.DruidEncryptUtil.java 用于对yaml中的东西加解密
package com.sunxiansheng.practice.server.util;

import com.alibaba.druid.filter.config.ConfigTools;

import java.security.NoSuchAlgorithmException;
import java.security.NoSuchProviderException;

/**
 * 数据库加密util
 */
public class DruidEncryptUtil {

    private static String publicKey;

    private static String privateKey;

    static {
        try {
            String[] keyPair = ConfigTools.genKeyPair(512);
            privateKey = keyPair[0];
            System.out.println("privateKey:" + privateKey);
            publicKey = keyPair[1];
            System.out.println("publicKey:" + publicKey);
        } catch (NoSuchAlgorithmException e) {
            e.printStackTrace();
        } catch (NoSuchProviderException e) {
            e.printStackTrace();
        }
    }

    public static String encrypt(String plainText) throws Exception {
        String encrypt = ConfigTools.encrypt(privateKey, plainText);
        System.out.println("encrypt:" + encrypt);
        return encrypt;
    }

    public static String decrypt(String encryptText) throws Exception {
        String decrypt = ConfigTools.decrypt(publicKey, encryptText);
        System.out.println("decrypt:" + decrypt);
        return decrypt;
    }

    public static void main(String[] args) throws Exception {
        String encrypt = encrypt("123456");
        System.out.println("encrypt:" + encrypt);
    }

}
8.创建启动类
1.PracticeApplication.java 注意写MapperScan和ComponentScan,还有启动类注解
package com.sunxiansheng.practice.server;

import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;

/**
 * Description: 练题模块
 * @Author sun
 * @Create 2024/6/25 15:48
 * @Version 1.0
 */
@SpringBootApplication
// 扫描mapper接口
@MapperScan("com.sunxiansheng.**.dao")
// 扫描service和controller注解
@ComponentScan("com.sunxiansheng")
public class PracticeApplication {
    
    public static void main(String[] args) {
        SpringApplication.run(PracticeApplication.class, args);
    }

}
9.创建配置文件
1.resource创建一个mapper文件夹

2.application.yml
