Websphere Application Server(08)--WAS Liberty部署Spring Boot应用

Posted on Aug 18, 2020 By Freud Kang

1. 创建Spring Boot应用

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>org.springframework.boot</groupId>
		<artifactId>spring-boot-starter-parent</artifactId>
		<version>2.6.7</version>
		<relativePath/> <!-- lookup parent from repository -->
	</parent>
	<groupId>com.example</groupId>
	<artifactId>springboot-liberty</artifactId>
	<version>0.0.1-SNAPSHOT</version>
	<properties>
		<java.version>11</java.version>
	</properties>
	<dependencies>
		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-web</artifactId>
		</dependency>

		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-test</artifactId>
			<scope>test</scope>
		</dependency>
	</dependencies>

	<build>
		<finalName>springboot-liberty</finalName>
		<plugins>
			<plugin>
				<groupId>org.springframework.boot</groupId>
				<artifactId>spring-boot-maven-plugin</artifactId>
			</plugin>
		</plugins>
	</build>

</project>

SpringbootLibertyApplication

package com.freud;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

@SpringBootApplication
@RestController
public class SpringbootLibertyApplication {

	@GetMapping("/hello")
	public String hello() {
		return "hello";
	}

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

}

application.yaml

server:
  servlet:
    context-path: /hifreud

2. 安装spring-boot feature

$ cd wlp/bin
# 查看已经安装的所有Features
$ ./productInfo featureInfo
# 安装所需的features
$ ./featureUtility installFeature springBoot-2.0

Successfully installed feature servlet-3.0.
Successfully installed feature jsonp-1.0.
Successfully installed feature jsp-2.2.
All features were successfully installed.
Start product validation...
Product validation completed successfully.

3. 创建对应的server

$ cd wlp/bin
# 创建Server
$ ./server create hifreud

Server hifreud created.

4. 准备server.xml，并将jar包赋值到 wlp/usr/servers/hifreud/apps 目录下

server.xml

<?xml version="1.0" encoding="UTF-8"?>
<server description="CPDS Server">

    <!-- Enable features -->
    <featureManager>
        <feature>springBoot-2.0</feature>
        <feature>servlet-3.1</feature>
    </featureManager>

    <!-- To access this server from a remote client add a host attribute to the following element, e.g. host="*" -->
    <httpEndpoint id="defaultHttpEndpoint"
                  httpPort="9080"
                  host="*" />

    <springBootApplication location="springboot-liberty.jar">
    </springBootApplication>

</server>

生成jar包并拷贝至 wlp/usr/servers/hifreud/apps 目录下

$ mvn clean install

5. 启动并验证

启动服务

$ cd wlp/bin
# 创建Server
$ ./server start hifreud

Starting server hifreud.
Server hifreud started with process ID 38852.

验证

$ curl -v http://localhost:9080/hifreud/hello
*   Trying 127.0.0.1:9080...
* Connected to localhost (127.0.0.1) port 9080 (#0)
> GET /hifreud/hello HTTP/1.1
> Host: localhost:9080
> User-Agent: curl/7.79.1
> Accept: */*
> 
* Mark bundle as not supporting multiuse
< HTTP/1.1 200 OK
< X-Powered-By: Servlet/3.1
< Content-Type: text/plain;charset=UTF-8
< Content-Length: 5
< Content-Language: en-CN
< Date: Tue, 17 May 2022 07:06:07 GMT
< 
* Connection #0 to host localhost left intact
hello%

停止服务

$ ./server stop hifreud 

Stopping server hifreud.
Server hifreud stopped.

6. Docker 方式运行此应用

Dockerfile

FROM docker.io/library/websphere-liberty:20.0.0.9-full-java8-ibmjava

#拷贝jar包
COPY --chown=1001:0  target/springboot-liberty.jar /config/apps/springboot-liberty.jar

COPY --chown=1001:0  server.xml /config/server.xml

# 如果需要root权限执行一些操作的
USER root

# 切回liberty 用户
USER 1001

EXPOSE 9080

server.xml

同上

启动

$ docker build -t hifreud-spring-boot-liberty:latest .
$ docker run --rm -p 9080:9080 hifreud-spring-boot-liberty:latest

验证

$ curl -v http://localhost:9080/hifreud/hello
*   Trying 127.0.0.1:9080...
* Connected to localhost (127.0.0.1) port 9080 (#0)
> GET /hifreud/hello HTTP/1.1
