迁移、升级说明 ​

注意: 此说明仅适用于 2.2.X 版本。

  • 1、依赖更新

    java
    <parent>
        <groupId>com.investoday.boot</groupId>
        <artifactId>spring-boot-starter-parent-x</artifactId>
        <version>2.3.0.X1.RELEASE</version>
    </parent>
    
    <dependency>
            <groupId>com.investoday.boot</groupId>
            <artifactId>common-invest</artifactId>
            <version>2.3.0-SNAPSHOT</version>
        </dependency>
    <parent>
        <groupId>com.investoday.boot</groupId>
        <artifactId>spring-boot-starter-parent-x</artifactId>
        <version>2.3.0.X1.RELEASE</version>
    </parent>
    
    <dependency>
            <groupId>com.investoday.boot</groupId>
            <artifactId>common-invest</artifactId>
            <version>2.3.0-SNAPSHOT</version>
        </dependency>

构建分层jar应用于Docker镜像中 ​

Spring Boot 2.3.0 开始支持jar分层，更好的优化打包镜像过程。 官方文档

  • 开启pom.xml中分层支持

    java
    <plugin>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-maven-plugin</artifactId>
    <configuration>
      <layers>
        <enabled>true</enabled>
      </layers>
    </configuration>
  </plugin>
    <plugin>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-maven-plugin</artifactId>
    <configuration>
      <layers>
        <enabled>true</enabled>
      </layers>
    </configuration>
  </plugin>

  • Dockerfile 修改支持分层

    核心是通过 Spring Boot 提供的 layertools 工具将jar进行拆分,然后通过 COPY指令去分别加载。

    注意: 涉及到环境变量等配置请写到第2个镜像编译中

    bash
    FROM invest/jre3 as builder
ADD test.jar /usr/application.jar
# ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","/usr/test.jar"]

#分层
WORKDIR /usr
RUN java -Djarmode=layertools -jar application.jar extract
FROM invest/jre3
MAINTAINER belkuy
VOLUME /tmp
ENV TIMEZONE=Asia/Shanghai
RUN ln -snf /usr/share/zoneinfo/$TIMEZONE /etc/localtime && echo $TIMEZONE > /etc/timezone
COPY --from=builder /usr/dependencies/ ./
COPY --from=builder /usr/spring-boot-loader/ ./
COPY --from=builder /usr/snapshot-dependencies/ ./
COPY --from=builder /usr/application/ ./

EXPOSE 8390
ENTRYPOINT ["java", "org.springframework.boot.loader.JarLauncher"]
    FROM invest/jre3 as builder
ADD test.jar /usr/application.jar
# ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","/usr/test.jar"]

#分层
WORKDIR /usr
RUN java -Djarmode=layertools -jar application.jar extract
FROM invest/jre3
MAINTAINER belkuy
VOLUME /tmp
ENV TIMEZONE=Asia/Shanghai
RUN ln -snf /usr/share/zoneinfo/$TIMEZONE /etc/localtime && echo $TIMEZONE > /etc/timezone
COPY --from=builder /usr/dependencies/ ./
COPY --from=builder /usr/spring-boot-loader/ ./
COPY --from=builder /usr/snapshot-dependencies/ ./
COPY --from=builder /usr/application/ ./

EXPOSE 8390
ENTRYPOINT ["java", "org.springframework.boot.loader.JarLauncher"]

新特性说明 ​

  • 可以使用来配置Redis的哨兵密码spring.redis.sentinel.password。
  • spring-boot-autoconfigure-processor现在，来自的输出是可重复的，从而使其与Gradle的构建缓存更好地配合。

弃用 ​

  • spring.http. 已经迁移至 server.servlet.encoding.``spring.mvc.和spring.codec.
  • SpringApplication#refresh(ApplicationContext)已被废弃，新路径SpringApplication#refresh(ConfigurableApplicationContext)。
  • server.error.include-stacktrac 的属性值 ON_TRACE_PARAM 被重命名为 ON_PARAM。
  • org.springframework.boot.autoconfigure.elasticsearch.rest.RestClientBuilderCustomizer 已被废弃，新路径 org.springframework.boot.autoconfigure.elasticsearch.RestClientBuilderCustomizer
