Nginx如何部署SpringBoot項目

1、新建一個yml檔application.yml

# 端口号
server:
  port: 2001

2、寫一個Controler測試類別

package com.example.demo1.controller;


import org.apache.logging.log4j.LogManager;
import org.apache.logging.log4j.Logger;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Component;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;

@RestController
@Component
@RequestMapping("/v1")
public class HelloController {
    final static Logger log = LogManager.getLogger(HelloController.class);
    @Value("${server.port}")
    private int port ;

    @RequestMapping(value = "", method = RequestMethod.GET)
    public String test() {
        return "invoke url /,port="+port;
    }

    @RequestMapping(value = "/test1", method = RequestMethod.GET)
    public String test1() {
        return "invoke url /test1,port="+port;
    }

    @RequestMapping(value = "/test2", method = RequestMethod.GET)
    public String test2() {
        return "invoke url /test2,port="+port;
    }
}

3、寫一個啟動類別

package com.example.demo1;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class Demo1Application {

    public static void main(String[] args) {
        SpringApplication.run(Demo1Application.class, args);
    }
}

4、我用到的pom檔案

<?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">

            <!--                </exclusion>-->

            <!--            </exclusions>-->

            <version>${log4j.version}</version>
        </dependency>
        <!--日志框架-->
    </dependencies>

    <build>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <version>3.7.0</version>
                <configuration>
                    <source>1.8</source>
                    <target>1.8</target>
                    <encoding>UTF-8</encoding>
                </configuration>
            </plugin>
            <plugin>

                <groupId>org.apache.maven.plugins</groupId>

                <artifactId>maven-assembly-plugin</artifactId>

                <version>2.5.5</version>

                <configuration>
                    <archive>
                        <manifest>
                            <mainClass>com.example.demo1.Demo1Application</mainClass>
                        </manifest>
                    </archive>
                    <descriptorRefs>
                        <descriptorRef>jar-with-dependencies</descriptorRef>
                    </descriptorRefs>
                </configuration>
                <executions>
                    <execution>
                        <id>make-assembly</id>
                        <phase>package</phase>
                        <goals>
                            <goal>single</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>
</project>

5、先在本地測試，啟動項目，看到這個就說明啟動成功了

  .   ____          _   .    \       _ _  _    \ c  / ___'_ __ _ _(_)_ __  __ _ \ \ \ \
( ( )\___ | '_ | '_| | '_ \/ _` | \ \ \ \
 \\ /  ___)| |_)| | | | | || (_| |  ) ) ) )
  '  |____| .__|_| |_|_| |_\__, | / / / /
 =========|_|==============|___/=/_/_/_/

6、測試，在瀏覽器中依序輸入

http://127.0.0.1:3001/v1

http://127.0.0.1:3001/v1/test1
#http:/ /127.0.0.1:3001/v1/test2

在瀏覽器中能看到埠號的列印資訊就表示成功了

7、maven編譯打成jar包

8、修改nginx.conf檔案

worker_processes  1;

events {
    worker_connections  1024;
}


http {
    include       mime.types;
    default_type  application/octet-stream;

    sendfile        on;
    
    keepalive_timeout  65;

    server {
        listen       89;
        server_name  nginx_server;

        location / {
            proxy_pass http://server_ip:3001/v1;
        }
        location /edu {
            proxy_pass http://server_ip:3001/v1/test1;
        }
        location /ymd {
            proxy_pass http://server_ip:3002/v1/test2;
        }
    }

}

nginx_server：nginx所在的伺服器的位址

server_ip：反向代理程式的伺服器的位址

#這裡我都是10.161.20.10

7、測試，根據訪問的路徑跳到不同的服務中

瀏覽器中輸入：

http://10.161.20.10 :90/

invoke url /,port=3001

http://10.161.20.10:90/test1

invoke url /test1,port=3001

http://10.161.20.10:90/test2

invoke url /test2,port=3002
