三、SpringBoot整合微服务&gateway&nginx
一、微服务项目集成MybatisPlus
创建自动生成代码子模块
1.基于maven方式创建子模块zmall-generator，用于结合mybatis-plus生成代码。
2. 在zmall-generator中引入mybatis-plus-generator依赖。该模块专用于mybatis-plus的代码生成，所以单独在此引入该依赖即可。
<!-- mybatis-plus-generator依赖 -->
<dependency>
<groupId>com.baomidou</groupId>
<artifactId>mybatis-plus-generator</artifactId>
<version>3.4.0</version>
</dependency>
3. 在src/main/resources下创建templates目录，并导入mybatis-generator生成代码模板页
4.在src/main/java下创建包com.zking.zmall，并导入generator下的CodeGenerator类用于代码生成

-
mpg.setStrategy(strategy);
-
mpg.setTemplateEngine(
new
FreemarkerTemplateEngine());
-
mpg.execute();
-
}
-
}
5.修改CodeGenerator类基本生成参数，并生成代码
-
//数据库连接参数
-
public
static
String
driver
=
"com.mysql.jdbc.Driver";
-
public
static
String
url
=
"jdbc:mysql://localhost:3306/zmall?characterEncoding=utf8&useSSL=false&serverTimezone=Asia/Shanghai&rewriteBatchedStatements=true";
-
public
static String username=
"root";
-
public
static String password=
"123456";
-
//父级别包名称
-
public
static
String
parentPackage
=
"com.zking.zmall";
-
//项目名设置（如果是SpringCloud项目则需要设置，其他为""即可）
-
public
static String projectName=
"/zmall-generator";
-
//代码生成的目标路径
-
public
static
String
generateTo
=
"/src/main/java";
-
//mapper.xml的生成路径
-
public
static
String
mapperXmlPath
=
"/src/main/resources/mapper";
-
//控制器的公共基类，用于抽象控制器的公共方法，null值表示没有父类
-
public
static String baseControllerClassName ;
-
//业务层的公共基类，用于抽象公共方法
-
public
static String baseServiceClassName ;
-
//作者名
-
public
static
String
author
=
"zking";
-
//模块名称，用于组成包名
-
public
static
String
modelName
=
"model";
注意：
修改数据库连接URL中的数据库名、数据库账号和密码；
修改父级别包名称
修改项目名，如果是SpringCloud项目则修改，不是则默认“”
先生成
zmall_product_category,zmall_product
此时直接运行代码生成类会报错，因为还缺少mybatis-plus的依赖
在自动生成代码子模块添加公共模块
此时再运行
就可以生成了
创建商品服务子模块
1.基于Spring Initializr方式创建商品服务模块zmall-product
2.在主模块pom.xml中加入商品服务子模块zmall-product
修改zmall-product的pom.xml
-
<?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 https://maven.apache.org/xsd/maven-4.0.0.xsd">
-
<modelVersion>4.0.0
</modelVersion>
-
<parent>
-
<groupId>com.zking.zmall
</groupId>
-
<artifactId>zmall
</artifactId>
-
<version>1.0-SNAPSHOT
</version>
-

-
<artifactId>zmall-product
</artifactId>
-
<dependencies>
-
<dependency>
-
<groupId>com.zking.zmall

-
<module>zmall-user
</module>
-
<module>zmall-generator
</module>
-
<module>zmall-product
</module>
-
</modules>
3.配置商品服务子模块zmall-product的application.yml配置文件
-
server
:
-
port
:
8020
-
spring
:
-
application
:
-
name
: zmall
-product
-
datasource
:
-
#type连接池类型 DBCP,C3P0,Hikari,Druid,默认为Hikari
-

-to
-camel
-case
: true
-
#日志配置
-

: debug
4. 在商品服务子模块中启动类上添加
ZmallProductApplication
-
package com.zking.zmall;
-
-
import org.mybatis.spring.annotation.MapperScan;
-
import org.springframework.boot.SpringApplication;
-
import org.springframework.boot.autoconfigure.SpringBootApplication;
-
-
@SpringBootApplication
-
@MapperScan({"com.zking.zmall.mapper"})
-
public
class
ZmallProductApplication {
-
-
public
static
void
main
(String[] args) {
-
SpringApplication.run(ZmallProductApplication.class, args);
-
}
-
-
}
5.将公共子模块中生成的service层代码复制到商品服务子模块zmall-product中，并删除掉非商品相关的service接口及实现类
6.创建junit实现接口测试
zmall-common模块
<!-- 用于test目录下的测试-->
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>4.12</version>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
</dependency>
ProductServiceImplTest
-
@RunWith(SpringJUnit4ClassRunner.class)
-
@SpringBootTest
-
public
class
ProductServiceImplTest {
-
-
@Autowired
-
private IProductService productService;
-
-
@Before
-
public
void
setUp
()
throws Exception {
-
}
-
-
@After
-
public
void
tearDown
()
throws Exception {
-
}
-
-
@Test
-
public
void
queryProduct
() {
-
List<Product> list = productService.list();
-
list.forEach(System.out::println);
-
}
-
}
拿到所有的数据
二、微服务项目集成Freemarker
1.在公共模块zmall-common中引入freemarker依赖
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-freemarker</artifactId>
</dependency>
2.在商品子模块zmall-product中添加首页和商品详情页面及公共资源（js/css/images）
将资料目录中的《易买网网页素材.rar》解压后，将其中Index.html、Product.html和js/css/images等等添加到项目的templates和static目录下，最好请将Index.html、Product.html页面首字母改成小写
导入资料目录中的common目录到项目的templates目录下
将页面中的头部申明<!DOCTYPE html ....>修改成<!DOCTYPE html>（支持H5风格）
在页面中通过<#include>指令引入common目录中的head.html
3.创建ProductController定义请求方法
ProductController
-
package com.zking.zmall.controller;
-
-
import com.baomidou.mybatisplus.core.conditions.query.QueryWrapper;
-
import com.zking.zmall.model.Product;
-
import com.zking.zmall.service.IProductService;
-
import org.springframework.beans.factory.annotation.Autowired;
-
import org.springframework.stereotype.Controller;
-
import org.springframework.ui.Model;
-
import org.springframework.web.bind.annotation.RequestMapping;
-
-
import java.util.List;
-
-
@Controller
-
public
class
ProductController {
-
-
@Autowired
-
private IProductService productService;
-
-
@RequestMapping("/index.html")
-
public String
index
(Model model){
-
//按照商品的销量降序排序获取销量排名Top5的商品
-
List<Product> products = productService.list(
new
QueryWrapper<Product>()
-
.orderByDesc(
"hot")
-
.last(
"limit 5"));
-
model.addAttribute(
"hots",products);
-
return
"index";
-
}
-
-
@RequestMapping("/product.html")
-
public String
detail
(Model model,Integer pid){
-
//根据商品ID查询商品详情信息
-
Product
product
= productService.getById(pid);
-
model.addAttribute(
"product",product);
-
return
"product";
-
}
-
}
运行启动类
4. 在index.html中绑定热门数据和product.html中绑定商品详情数据
index.html
替换为
-
<ul class="featureUL">
-
<#--判断hots是否为空-->
-
<#if hots??>
-
<#--循环遍历热销商品-->
-
<#list hots as it>
-
<li class="featureBox">
-
<div class="box">

效果图：
三、SpringBoot整合微服务&gateway&nginx
gateway
请求链路要求：客户端发送请求先经过nginx，再用nginx转至内部访问网关gateway，最后由网关服务的路由规则转发到微服务的内部服务。
整合微服务之商品服务zmall-product
在公共模块zmall-common中导入微服务相关依赖
-

创建并配置网关gateway服务
1.基于Spring initializr方式创建网关模块zmall-gateway
并且将网关模块zmall-gateway和父模块进行关联
2.配置pom.xml添加nacos和gateway的依赖
-
<modelVersion>
4.0
.0</modelVersion>
-
<parent>
-
<groupId>com.zking.zmall</groupId>
-
<artifactId>zmall</artifactId>
-
<version>
1.0-SNAPSHOT</version>
-
</parent>
-
<artifactId>zmall-gateway</artifactId>
-
<dependencies>
-
<!--gateway 注意 此模式不能引入starter-web -->
-
<dependency>
-
<groupId>org.springframework.cloud</groupId>
-
<artifactId>spring-cloud-starter-gateway</artifactId>
-
</dependency>
-
-
<!--nacos客户端-->
-
<dependency>
-
<groupId>com.alibaba.cloud</groupId>
-
<artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
-
</dependency>
-
-
<dependency>
-
<groupId>org.projectlombok</groupId>
-
<artifactId>lombok</artifactId>
-
</dependency>
-
-
<dependency>
-
<groupId>org.apache.commons</groupId>
-
<artifactId>commons-lang3</artifactId>
-
</dependency>
-
</dependencies>
此时网关模块的pom依赖
-
<?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 https://maven.apache.org/xsd/maven-4.0.0.xsd">
-
<modelVersion>4.0.0
</modelVersion>
-
<parent>
-
<groupId>com.zking.zmall
</groupId>
-
<artifactId>zmall
</artifactId>
-
<version>1.0-SNAPSHOT
</version>
-
</parent>
-
<groupId>com.zking
</groupId>
-
<artifactId>zmall-gateway
</artifactId>
-
-
<dependencies>
-
<!--gateway 注意 此模式不能引入starter-web -->
-
<dependency>
-
<groupId>org.springframework.cloud
</groupId>
-
<artifactId>spring-cloud-starter-gateway
</artifactId>
-
</dependency>
-
-
<!--nacos客户端-->
-
<dependency>
-
<groupId>com.alibaba.cloud
</groupId>
-
<artifactId>spring-cloud-starter-alibaba-nacos-discovery
</artifactId>
-
</dependency>
-
-
<dependency>
-
<groupId>org.projectlombok
</groupId>
-
<artifactId>lombok
</artifactId>
-
</dependency>
-
-
<dependency>
-
<groupId>org.apache.commons
</groupId>
-
<artifactId>commons-lang3
</artifactId>
-
</dependency>
-
</dependencies>
-
-
</project>
3.修改启动类，向nacos进行注册
-
package com.zking.zmall;
-
-
import org.springframework.boot.SpringApplication;
-
import org.springframework.boot.autoconfigure.SpringBootApplication;
-
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
-
-
@EnableDiscoveryClient
-
@SpringBootApplication
-
public
class
ZmallGatewayApplication {
-
-
public
static
void
main
(String[] args) {
-
SpringApplication.run(ZmallGatewayApplication.class, args);
-
}
-
-
}
4.配置application.yml设置gateway路由转发规则
server:
port: 8000
spring:
application:
name: zmall-gateway
cloud:
nacos:
discovery:
server-addr: localhost:8848
gateway:
routes:
- id: product_route
uri: lb://zmall-product # lb指的是从nacos中按照名称获取微服务,并遵循负载均衡策略
predicates:
- Path=/product-serv/**
filters:
- StripPrefix=1
5.将易买网网页素材中的公共静态资源js/css/images复制到gateway网关服务中
这里请注意了，之前在商品服务模块zmall-product中已经配置了易买网的静态资源，为什么还要在gateway网关服务中再配置一次呢？这是因为当请求经过gateway网关服务后会进行断言条件匹配和条件路径截取等操作，从而导致gateway网关路由转发后静态资源失效404的问题，所以特此在gateway网关服务中也配置一次易买网网页素材中的公共静态资源js/css/images，确保能正常访问
解决方案：（使用nginx动静分离方式实现） 配置静态资源访问服务器，将各个微服务模块中的静态访问资源迁移到静态资源访问服务器中，然后通过http方式访问即可。
在gateway网关服务中配置一次易买网网页素材中的公共静态资源js/css/images前
在gateway网关服务中配置一次易买网网页素材中的公共静态资源js/css/images后
安装配置Windows版nginx
1.解压nginx-1.18.0.zip至任意目录
下载安装包
双击 以上红框 就可以访问到nginx了
确保nginx是能用的 然后关掉进程 进行配置
此时就访问不到了
2.进入conf目录，并修改nginx.conf配置文件
server
{
listen 80;
server_name zmall.com;
proxy_redirect off;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;location / {
proxy_pass http://127.0.0.1:8000/;
}
}
安装配置SwitchHosts
1.直接双击exe文件即可安装SwitchHosts
桌面就有这个
2. 打开SwitchHosts设置一级域名
出现这种情况
就用管理员身份运行
再次启动nginx（最后运行nginx根目录下的nginx.exe启动nginx ）
如果出现IIS7，那么cmd窗口中执行下列指令
net stop w3svc
请求链路测试
单独访问商品服务：http://localhost:8020/index.html
通过gateway访问：http://localhost:8000/product-serv/index.html
通过nginx访问：http://zmall.com/product-serv/index.html
单独访问商品服务
通过gateway访问
通过nginx访问
