Nginx如何部署SpringBoot项目

本篇内容介绍了“Nginx如何部署SpringBoot项目”的有关知识，在实际案例的操作过程中，不少人都会遇到这样的困境，接下来就让小编带领大家学习一下如何处理这些情况吧！希望大家仔细阅读，能够学有所成！

新建一个yml文件 application.yml

# 端口号server:  port: 2001

编写一个Controler测试类

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;    }}

编写一个启动类

package com.example.demo1;import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.SpringBootApplication;@SpringBootApplicationpublic class Demo1Application {    public static void main(String[] args) {        SpringApplication.run(Demo1Application.class, args);    }}

我用到的pom文件

<?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>org.springframework.boot</groupId>        <artifactId>spring-boot-starter-parent</artifactId>        <version>2.7.6</version>        <relativePath/> <!-- lookup parent from repository -->    </parent>    <groupId>com.example</groupId>    <artifactId>demo1</artifactId>    <version>0.0.1-SNAPSHOT</version>    <name>demo1</name>    <description>Demo project for Spring Boot</description>    <properties>        <java.version>1.8</java.version>        <log4j.version>2.19.0</log4j.version>    </properties>    <dependencies>        <dependency>            <groupId>org.springframework.boot</groupId>            <artifactId>spring-boot-starter</artifactId>        </dependency>        <dependency>            <groupId>org.springframework.boot</groupId>            <artifactId>spring-boot-starter-web</artifactId>            <!--            <exclusions>-->            <!--                <exclusion>-->            <!--                    <groupId>ch.qos.logback</groupId>-->            <!--                    <artifactId>logback-classic</artifactId>-->            <!--                </exclusion>-->            <!--            </exclusions>-->            <exclusions>                <exclusion>                    <groupId>org.springframework.boot</groupId>                    <artifactId>spring-boot-starter-logging</artifactId>                </exclusion>            </exclusions>        </dependency>        <dependency>            <groupId>org.springframework.boot</groupId>            <artifactId>spring-boot-starter-test</artifactId>            <!-- <scope>test</scope> -->        </dependency>        <!--日志框架-->        <dependency>            <groupId>org.apache.logging.log4j</groupId>            <artifactId>log4j-api</artifactId>            <version>${log4j.version}</version>        </dependency>        <dependency>            <groupId>org.apache.logging.log4j</groupId>            <artifactId>log4j-core</artifactId>            <version>${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>

先在本地测试，启动项目，看到这个就说明启动成功了

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

测试，在浏览器中依次输入

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

在浏览器中能看到端口号的打印信息就说明成功了

maven编译打成jar包

修改nginx.conf文件

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所在的服务器的地址

server_ip：反向代理的服务器的地址

这里我都是10.161.20.10

测试，根据访问的路径跳转到不同的服务中

浏览器中输入：

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
