Spring Boot CLI
Spring Boot CLI是一个命令行工具，如果想使用Spring进行快速开发可以使用它。它允许你运行Groovy脚本，这意味着你可以使用熟悉的类Java语法，并且没有那么多的模板代码。你可以通过Spring Boot CLI启动新项目，或为它编写命令。
Spring Boot CLI 安装
下载二进制文件
代码语言：shell复制wget https://repo.spring.io/release/org/springframework/boot/spring-boot-cli/2.3.3.RELEASE/spring-boot-cli-2.3.3.RELEASE-bin.tar.gz -P /usr/local/src
tar zxvf /usr/local/src/spring-boot-cli-2.3.3.RELEASE-bin.tar.gz -C /usr/local/
添加环境变量
代码语言：shell复制tee > /etc/profile.d/spring.sh <<- 'EOF'
export SPRING_HOME=/usr/local/spring-2.3.3.RELEASE
export CLASSPATH=.:${SPRING_HOME}/lib:$CLASSPATH
export PATH=${SPRING_HOME}/bin:$PATH
EOF
source /etc/profile

See 'spring help <command>' for more information on a specific command.
运行脚本
- 启动groovy脚本
[[ -d "/usr/local/src/groovy" ]] || mkdir -pv /usr/local/src/groovy
tee > /usr/local/src/groovy/helloworld.groovy <<- 'EOF'
@RestController
class Hello {
@RequestMapping("/hello")
def hello() {
return "Hello World Groovy!";
}
}
EOF
spring run /usr/local/src/groovy/helloworld.groovy --server.port=9000 &
- 启动java脚本
[[ -d "/usr/local/src/java" ]] || mkdir -pv /usr/local/src/java
tee > /usr/local/src/java/helloworld.java <<- 'EOF'
@RestController
public class Hello {
@RequestMapping("/hello")
public String hello() {
return "Hello World Java!";
}
}
EOF
spring run /usr/local/src/java/helloworld.java --server.port=9001 &
使用docker 运行spring boot项目
创建Dockerfile文件
代码语言：shell复制tee > /usr/local/src/groovy/Dockerfile-spring <<- 'EOF'
FROM openjdk:8-jdk-alpine

ARG JAR_NAME
ENV JAR_NAME=$JAR_NAME
PORT=$PORT

&& rm -rf /usr/local/share/spring-boot-cli-2.3.3.RELEASE-bin.tar.gz
&& rm -rf /var/cache/apk/*
EXPOSE ${PORT}
#CMD ["/bin/bash"]
ENTRYPOINT ["sh","-c","spring run $JAR_NAME -- --spring.config.location=$APPLICATION_DIR --spring.profiles.active=$APPLICATION_ENV"]
EOF
打包docker 镜像
代码语言：shell复制docker build -t spring:v1.0 --build-arg PORT=9000 --build-arg JAR_NAME=helloworld.groovy -f Dockerfile-spring .
运行docker 容器
代码语言：shell复制docker run --rm -itd spring:v1.0 sh
curl -v localhost:9000
初始化项目
执行如下命令，初始化出来一个maven项目工程
代码语言：shell复制spring init -d=web --build=gradle --name devops --java-version 1.8 --groupId cn.jt7t.springboot --artifactId springboot-devops --language java --boot-version 2.3.2.RELEASE --type maven-project --extract
对应参数说明如下
代码语言：text复制1、-d 添加依赖
2、--build 编译类型
3、--java-version java版本
4、--groupId 组织名称，一般为域名 项目名
5、--artifactId 子模块，一般为部分或岗位名称
6、--language 语言类型
7、--boot-version springboot版本
8、--type 项目类型
9、--extract 在当前目录解压
生成的文件目录如下：
代码语言：shell复制.
