SqlSession
调用mapper配置文件,避免编写额外的接口。
application.yml
里配置
server.servlet.context-path
属性为
/api
,所有请求默认带
api
前缀。
property-naming-strategy = SNAKE_CASE
配置。
application.yml
中配置
spring.jackson.property-naming-strategy
的属性为
SNAKE_CASE
,将Java属性的驼峰命名转换为http的标准下划线命名。
使用Duration配置yml文件,允许设置时间单位或者数据单位。参考: Spring Boot官方手册3.0.4 Properties Conversion
配置样例参考配置文件
application.yml
的
jwt.validtiy
属性
jwt:
# 24 hours
validtiy: 24h
代码样例参考
JwtTokenPrivider
的
validtiyInMs
属性
@Value("${jwt.validtiy}")
@DurationUnit(ChronoUnit.MILLIS)
private Duration validityInMs;

主目录创建config、logs两个文件夹
主目录放置start.sh和stop.sh两个脚本文件,并添加可执行权限
config目录下放置application.properties或application*.yml和log4j2.xml文件
修改log4j2.xml文件,增加日志文件输出

参考How to deploy Maven projects to Artifactory with GitLab CI/CD添加.gitlab-ci.yml文件,只做build,test,所以文件配置如下
image: maven:latest
stages:
- build
- test
variables:
MAVEN_CLI_OPTS: "-s .m2/settings.xml --batch-mode"
MAVEN_OPTS: "-Dmaven.repo.local=.m2/repository"
cache:
paths:
- .m2/repository/
- target/
build:
stage: build
script:
- mvn $MAVEN_CLI_OPTS compile
test:
stage: test
script:
- mvn $MAVEN_CLI_OPTS test
为了加速maven仓库访问,在工程中配置.m2/settings.xml
文件,并且在该文件中的仓库镜像配置阿里云maven加速。
<mirror>
<id>alimaven</id>
<name>aliyun maven</name>
<url>http://maven.aliyun.com/nexus/content/groups/public/</url>
<mirrorOf>central</mirrorOf>

先说结论:
服务器操作系统CentOS Linux release 7.6.1810
,仅仅调整session的openfile至10万,未做任何其他参数调整
安装Open JDK11.0.8
,Java进程启动参数-server -Xss256k -Xms8g -Xmx8g
服务器配置:VMWare虚拟化16vCPU,32G,稳定运行在并发3000个请求/秒左右,国外有人测试不调整任何参数能够稳定在5000个并发以内
