注意

Maven

Maven 项目打包源文件 *-sources.jar

可以解决本地打包无法下载源码问题

Cannot download sources Sources not found for: com.v0710:do-common:1.0.0

<build>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>

Springboot

1，多模块项目

在Springboot 多模块项目中，不要在父pom文件和其他没有启动类的项目中配置 build 标签。只在需要的子项目的pom文件中配置（一般是web项目）

2，mapper.xml文件

1，mapper.xml放在`非resources`下

1-1，设置pom.xml

<!-- 过滤xml文件-->
<resources>
    <resource>
        <!-- java目录 -->
        <directory>src/main/java</directory>
        <includes>
            <include>**/*.xml</include>
        </includes>
        <filtering>false</filtering> 
    </resource>
     <resource>
          <!-- resources --> 
        <directory>src/main/resources</directory>
        <includes>
            <include>**.*</include>
            <include>**/*.*</include><!-- i18n能读取到 -->
            <include>**/*/*.*</include>
         </includes>
        <filtering>false</filtering>
    </resource>
</resources>

<plugin>
    <executions>
        <execution>
            <goals>
                <goal>repackage</goal><!--可以把依赖的包都打包到生成的Jar包中-->
            </goals>
        </execution>
    </executions>
</plugin>

1-2，配置配置文件配置mapper映射路径

mybatis-plus.mapper-locations=com/yifan/mapper/xml/*.xml

2，mapper.xml 放在`resources`目录下

2-1，设置mapper映射路径

mybatis-plus.mapper-locations=classpath:xml/*.xml

You ran ‘git add’ with neither ‘-A (–all)’ or ‘–ignore-removal’,
whose behaviour will change in Git 2.0 with respect to paths you removed.
Paths like ‘Gitbook.md’ that are

git fetch –all
git reset –hard origin/master
git pull

git config --global user.name "MEliauk"
git config --global user.email "2050781802@qq.com"
git config --global core.autocrlf input
ssh -T git@gitee.com

#拉取最新代码部署
cd /apps/gitbook/
CURRENT=pwd
echo “$CURRENT”
git fetch –all
git reset –hard origin/master
git pull
echo “拉取代码完成。。。。。”

git remote add origin https://gitee.com/MEliauk/note.git

3，springboot项目配置https

SpringBoot自带的是tomcat服务器一般使用的.jks文件配置SSL加密。

配置文件

server.ssl.key-store=classpath:v0710.top.jks
server.ssl.key-store-password=77bo2c1fe56ca3
server.ssl.key-store-type=JKS

在resource目录下放入jks文件

同时配置http和https都能访问

新整配置

#http端口号
http.port=18092

在启动了中添加

// 获取配置端口
@Value("${http.port}")
private Integer httpPort;
 
@Bean
public ServletWebServerFactory servletContainer() {
    TomcatServletWebServerFactory tomcat = new TomcatServletWebServerFactory();
    // 添加http
    tomcat.addAdditionalTomcatConnectors(createStandardConnector());
    return tomcat;
}
 
// 配置http
private Connector createStandardConnector() {
    Connector connector = new Connector("org.apache.coyote.http11.Http11NioProtocol");
    connector.setPort(httpPort);
    return connector;
}

4，SpringBoot项目http访问上传文件接口正常但切到https访问上传文件接口失败

springboot内置的Tomcat存在bug，进行升级即可。（注：之前是9.0.31，升级到了9.0.41，问题得到了解决）

springboot项目在调文件上传接口上传文件时使用http访问请求可以上传成功，但是切换到https请求时就会报错，报错提示:Processing of multipart/form-data request failed. Stream ended unexpectedly。

报错信息

Failed to parse multipart servlet request; nested exception is java.io.IOException: org.apache.tomcat.util.http.fileupload.impl.IOFileUploadException: Processing of multipart/form-data request failed. Stream ended unexpectedly

解决

<properties>
    <tomcat.version>9.0.41</tomcat.version>
</properties>

<dependency>
    <groupId>org.apache.tomcat</groupId>
    <artifactId>tomcat-juli</artifactId>
    <version>${tomcat.version}</version>
</dependency>

1，JSON 转换注意

JSONUtil.toJsonStr(list, JSONConfig.create().setIgnoreNullValue(false))
    
IgnoreNullValue // 是否忽略null值
