一、项目打包：  
1.mvn项目：`./mvnw -Pprod clean package`  
2.gradle项目：`gradle bootRepackage -Pprod`  
3.idea打包：mvn—package  
二、运行已打war包：`java -jar target/*.war`

三、1.导入实体文件：`jhipster import-jdl ./my-jdl-file.jdl`  
2.单独新建实体：`jhipster entity <entityName>`  
3.更新：`yo jhipster:entity 需要修改的实体名`  
具体见文档  
四、`git-commit-id-plugin`报错：

[ERROR] Failed to execute goal pl.project13.maven:git-commit-id-plugin:2.2.4:rev
      ision (default) on project invoiceproject: Execution default of goal pl.project1
      3.maven:git-commit-id-plugin:2.2.4:revision failed: Unable to load the mojo 'rev
      ision' in the plugin 'pl.project13.maven:git-commit-id-plugin:2.2.4'. A required
      class is missing: com/google/common/base/Function

解决示例：

修改`git-commit-id-plugin`版本，可能当前集成的版本兼容不好，修改为可以版本
    
         <groupId>pl.project13.maven</groupId>
           <artifactId>git-commit-id-plugin</artifactId>
         <version>2.1.15</version>

五、liquibase数据库升级

1. Database updates with the Maven liquibase:diff goal:       ./mvnw liquibase:diff
    Modify your JPA entity (add a field, a relationship, etc.)
    Compile your application (this works on the compiled Java code, so don’t forget to compile!)
    Run ./mvnw liquibase:diff (or ./mvnw compile liquibase:diff to compile before)
    A new “change log” is created in your src/main/resources/config/liquibase/changelog directory
    Review this change log and add it to your src/main/resources/config/liquibase/master.xml file, so it is applied the next time you run your application

2.`使用Maven liquibase:diff更新数据库` `./mvnw liquibase:diff`  
3.问题：

2018-07-14 11:50:09.898 ERROR 9344 --- [eapp-Executor-1] i.g.j.c.liquibase.Async
    SpringLiquibase   : Liquibase could not start correctly, your database is NOT re ady: Validation Failed: 1 change sets check sum config/liquibase/changelog/20180711041324_added_entity_FGLFpDetails.xm l::20180711041324-1::jhipster was: 7:da92801ba8e00dea5ecc3b97d1132a29 but is now : 7:bce6e1175a926a4f28d32d87c444b4c6

处理：

./mvnw liquibase:clearCheckSums

4.问题：

default-cli) on project singleapp: Error setting up or running Liquibase: liquib
    ase.exception.DatabaseException: java.sql.SQLException: Access denied for user ' root'@'localhost' (using password: NO) -> [Help 1]

处理：升级没有配置数据库地址等，原为空，修改参照下

<configuration>
               <changeLogFile>src/main/resources/config/liquibase/master.xml</changeLogFile>
                        <diffChangeLogFile>src/main/resources/config/liquibase/changelog/${maven.build.timestamp}_changelog.xml</diffChangeLogFile>
                <driver>com.mysql.jdbc.Driver</driver>
                <url>jdbc:mysql://localhost:3306/singleapp</url>
                <defaultSchemaName>singleapp</defaultSchemaName>
                <username>root</username>
                <password>123456</password>
                <referenceUrl>hibernate:spring:com.xwz.myjhipster.domain?dialect=org.hibernate.dialect.MySQL5InnoDBDialect&hibernate.physical_naming_strategy=org.springframework.boot.orm.jpa.hibernate.SpringPhysicalNamingStrategy&hibernate.implicit_naming_strategy=org.springframework.boot.orm.jpa.hibernate.SpringImplicitNamingStrategy</referenceUrl>
                <verbose>true</verbose>
                <logging>debug</logging>
    </configuration>

六、很难排查问题：  
1.![这里写图片描述][70]  
VO与DTO的set 与get方法报错：  
原因：用了lombok，怎么处理待后续；这里推荐屏蔽lombok，写setget方法  
2.另一种是`maven-compiler-plugin`插件版本有问题
